INTRODUCTION
PURPOSE: To provide a concise, standardized set of instructions and
procedures to assist U.S. Army Accident Investigation/Installation-level
accident (CAI/IAI) boards. This handbook is designed to supplement DA
PAM 385-40, as a daily use guide for accident investigations.

APPLICABILITY: The manual is intended for use by accident investigation

boards and as a guide for field accident investigators who are appointed
by their local command. Contents of this guide are intended for
both aviation and non-aviation (ground) accidents. Unless otherwise
stated, information pertains to either type accident. Where necessary,
differences have been delineated. Additionally, this guide does not cover
all circumstances. Contact the operations officer, USACRC, DSN 558-
3410/2660, commercial (334) 255-3410/2660 for special instructions
concerning situations and circumstances not covered in this handbook.

For a digital copy of this handbook and additional information for use
during an accident investigation, type “USACRC” into a Web search
engine. Once at the U.S. Army Combat Readiness Center’s webpage
click the drop down arrow on “REPORTING & INVESTIGATION” then click
“Tools” for downloadable information and investigation tools.

Point of contact for accident investigations and this guide is U.S. Army
Combat Readiness Center, chief, Accident Investigations Division, DSN
558-2194, commercial (334) 255-2194.

CHAPTER 1

Getting Started
1-1. NOTIFICATION.

CH 1
a. General. By nature of an accident being an unplanned event,
notification and lead time for preparations are very short. Board
members can expect 24 hours or less from notification to forming a local
Installation-level Accident Investigation (IAI) Board or the deployment
of a Centralized Accident Investigation (CAI) from the U.S. Army Combat
Readiness Center.

b. Initial Actions. After initial notification, the board president or

recorder sends the accident unit’s point of contact (POC) a checklist
(see Appendix A) of actions and materials needed for the board. This
checklist helps focus the unit POC and assists the board in preventing
unnecessary delays to the investigation.

1-2. ARRIVAL.
a. General. Upon arrival, the board president and recorder meet with
the unit POC, set up the board room, form the board, visit the accident
site, if possible, and conduct in-briefs with the appointing authority/
chain of command.

b. Unit POC. Unit POCs are your primary conduit for data collection
from the accident unit, scheduling of interviews, and communication
with the chain of command. In most cases the POC is the installation or
unit safety officer. During your initial meeting with the unit POC, check
on scheduling an in-brief with the appointing authority and accident
unit’s battalion and brigade commanders. Additionally, check on
orders for the board. The board is operating under the authority of the
appointing authority and the absence of orders can sometimes delay the
gathering of important data.

c. Board Room. The board room is your primary work and interview
area during the investigation. It’s important to establish the board’s
working area as quickly as possible. In cases of remote accident
sites, this may not always be possible. If the accident site is near the
installation or designated work area, the board president may elect to
establish the work area after ensuring that the preliminary accident site
investigation is ongoing. An ideal board room is similar to a conference
room with enough room to work and seat all the board members,
away from common work areas, to facilitate confidentiality of the
investigation.

1-1
 d. Forming the Board. One of the team’s first challenges is to
assemble the board. In most cases, the board members do not arrive
simultaneously. Its members may be provided by the host installation
or may be required to travel from other locations. Selection, notification
and travel of other board members may require days instead of hours.
CH 1

Whatever the circumstance, the board president and recorder must

develop a plan to gain control of other board members and advisors
immediately upon arrival. Administrative orders and costs that are
associated with the travel of board members are the responsibility
of the accident unit and should be controlled and coordinated by the
accident unit.

e. Accident Site. Get to the accident site as quickly and safely as

possible. There are two important reasons. First, the board must
gain control of the accident site and record any evidence that may be
perishable. Trained safety personnel usually attempt to preserve the
site to the degree possible, however well-intentioned, but uninformed
interested personnel often feel the need to inspect the scene personally
and may inadvertently destroy evidence in the process. Impending
inclement weather is an obvious scenario where the board may find it
necessary to view the site even during periods of darkness. The board
checks the weather at the accident site and makes a determination with
the unit POC and equipment subject matter expert (SME) as to whether
or not fluid samples will be compromised by the effects of inclement
weather. If so, have the unit POC coordinate with maintenance
personnel to take the required samples prior to the onset of inclement
weather. These samples are sequestered with the equipment’s records
and logbooks and made available to the board upon arrival. Second,
display a sense of professional urgency to begin the investigation.

f. In-briefs. The board president should in-brief the appointing

authority as soon as possible. The appointing authority in-brief is
informal and does not require media support or a briefing room. Often,
it is done in the appointing authority’s (or designated representative’s)
office. The purpose is to inform the appointing authority regarding
the board’s mission, composition and requirements (see Appendix
B). On occasion, the appointing authority may provide additional
guidance regarding areas that he feels need particular emphasis. The
board restricts their comments to the process the investigation will
undertake and the specific roles and responsibilities of each subject
matter expert (SME) assigned to the board. Discuss the materiel,
human and environmental factors teams. Avoid speculation about any
preliminary data gathered either en route to the accident or during any
initial communications with members of the accident unit. Reinforce
1-2
the investigative process and that it is not until the board conducts
deliberations that its findings are developed. Inform the commander
that the board will advise the unit of any immediate safety concerns that
are identified during the process of the investigation. It is important
to note that the decision to continue flight or ground operations is a

CH 1
commander’s decision and the board does not make that determination
on behalf of the unit.

1-3. ORGANIZATION & PLANNING. (See DA PAM 385-40, Paragraph 2-1)

a. Board In-brief. Before starting the investigation, it is important to
ensure that all board members understand the investigation concept
and plan (see Appendix C). The investigation plan is a systematic process
that ensures continuity of effort from the preliminary examination of the
accident site to the submission of the final report. The plan is divided
into four phases-

(1) Organization and preliminary examination (two days)

(2) Data collection (eight days)

(3) Data analysis and deliberations (two days)

(4) Completing the technical report (two days)

b. Phase 1 - Organization and preliminary examination. This phase

provides the opportunity for the board president to organize the
board personnel into materiel and human factors board members
for the investigation. This is accomplished in a board meeting before
departing for the accident scene. This meeting ensures that every board
member understands the areas of the investigation for which they are
responsible, the initial tasks to be accomplished (see paragraphs below)
and the data elements to be collected to complete the report. The
board is also briefed by the unit/installation safety director/officer on
the status of preliminary actions. Once the board arrives at the accident
site, its members make a controlled entry (ensuring the site, to include
ground scar/mark, is not disturbed) to get a “mental picture” of the
physical layout. This orientation usually requires less than 30 minutes. If
the board cannot arrive at the scene with adequate daylight remaining,
the preliminary examination may be delayed until the following
morning.

c. Phase 2 - Data collection. Human, environmental and materiel

1-3
 factors are interrelated as each influence the performance of man and
machine. Divide data collection into the following areas:

(1) Environmental Factors. Collection of environmental evidence

is simultaneous and inclusive with the human and materiel factors
CH 1

evidence collection.

(2) Materiel Factors (see Appendix F). Materiel factors concerns

gathering data necessary to evaluate the performance or design of the
vehicle, aircraft, buildings, ground support equipment or other material
involved. The materiel factors team also conducts a thorough review of
previous maintenance performed on the accident equipment to check
for inadequate maintenance procedures.

(3) Human Factors (see Appendix G). Human factors are primarily
concerned with gathering data necessary to evaluate the job
performance of all personnel who influenced the operation that resulted
in the accident. Data collection should enable analysis focused on the
five dimensions of human factors (individual, leader, training, support,
and standards failures). To accomplish this the human factors team
gathers all associated training records, unit SOPs, authorized briefer
memos, unit training calendars and plans, unit manning documents and
critical shortage MOSs, the mission brief and risk assessment.

d. Phase 3 - Data Analysis. The analysis function is an ongoing process

throughout the data collection phase. Conclusions derived from the
analysis are the basis for developing findings and recommendations.
The analysis is thorough and focuses on determining why the accident
occurred. This drives the analytical effort throughout the investigation,
so that findings and recommendations can be developed that have the
best potential for preventing similar accidents. (See Chapter 4 for a
detailed discussion of data analysis).

e. Phase 4 - Completing the technical report. In this phase, the board

ensures all relevant evidence gathered is carefully recorded (Chapter
10 provides detailed instructions on completing the report). It is not
unusual for some of the evidence to be contradictory. Contradictory
evidence is discussed and resolved to the extent possible in the analysis.

Investigation Process.
(See DA PAM 385-40, Paragraph 1-5 & Chapter 2)

2-1. OVERVIEW.

CH 1 CH 2
a. 3W Approach. The on-site accident investigation process utilizes
the “3W” approach. The “3W” approach reveals adverse interactions
of man, machine and environment, which caused or contributed to the
accident.

(1) What happened (mistake/error, materiel failure, and/

or environmental factor). Identify key factors (human, materiel,
environmental), which caused or contributed to the accident. In the case
of injuries, explain how they happened. (See DA PAM Tables B-1 through
B-6 for additional information/guidance)

2-1
 (2) Why it happened (root cause(s)/system inadequacy(ies)). Identify
the system inadequacy(ies) that permitted the mistake/error to occur,
the materiel to fail/malfunction or the environment to become a
factor in the accident. Identifying and resolving root causes/system
inadequacies are the keys to preventing future accidents. It’s important
to remember the purpose of Army accident investigation is to identify
underlying causes and contributing factors that led or will lead to
future accidents and not fault. Fault is a function more appropriate for
collateral boards or legal inquiries and can often be a distraction to CAI/
CH 1 CH 2

IAIs during the conduct of an investigation. Identifying who is at fault

does little or nothing in pointing out how to prevent a similar accident in
the future. Focus on why, not who.

(3) What to do about it (recommendations). Identify the

recommended actions and identify the proponent activity or lowest
level of command that is most responsible for taking action targeted at
eliminating/correcting the system inadequacies/root causes (both at
the unit and, if applicable, Army levels). It is important to provide the
local commander with recommendations to address his local situation,
but it is equally important to provide the Department of the Army with
recommendations to address Armywide hazards. Recommendations are
based on the circumstances as they existed at the time of the accident.
Often units make immediate changes based on the early understandings
of an accident. While that is a unit commander’s prerogative and
certainly appropriate it does not affect the resulting findings and
recommendations. If the circumstances existed in this organization
they most likely exist in other organizations and it is the responsibility of
the CAI/IAI to ensure the widest dissemination of accident prevention
information possible, through their report. Additionally, the appropriate
activity responsible for correcting each identified system inadequacy
is notified by the U.S. Army Combat Readiness Center. This process is
continually followed up to ensure recommendations have been adopted
by the field and that appropriate measures are in place to ensure
accident prevention.

2-2. DATA COLLECTION.

a. Crucial to any investigation is the gathering of data and physical
evidence. Tactical situation determines the level of detail collected
in a combat zone. The data/evidence collected during an accident
investigation becomes the very basis of the accident investigation
board’s analysis and conclusions. Therefore, a thorough effort to collect
all relevant data and evidence must be made.

2-2
 b. Data and evidence collected during an investigation should include:

(1) Physical evidence - Matter related to the accident such as

equipment, parts, debris, hardware, voice recorders and other physical
items. NOTE: It is critical to preserve digital source data from aircraft/

CH 1 CH 2
vehicle recording devices (See Appendix J).

(2) Verbal evidence - Witness statements and observations.

(3) Documentary evidence - Paper and electronic information, such as

records, reports, policies and procedures, photos, videos, accident site
graphs, duty logs, board proceedings and notes, board member notes,
etc.

CH 3 CH 4
(4) Recording of anomalies – Through the course of collecting data and
evidence there are those factors uncovered by the board that deviate
from the norm or expectations. The board records these anomalies for
discussion and analysis during the analysis phase of the investigation.
Typically, anomalies are recorded under the headings of environmental,
human and materiel factors.

c. The collection of evidence and data comes from six major areas-

CH 5 CH 6
(1) The Accident Scene. Prepare a site diagram that captures positions
of debris, equipment, tools, body parts and injured persons. Also,
check with the host organization’s designated representative to see if
any photographs, diagrams, videos or other pictorial representations
of the scene have been collected and are available for viewing. When
feasible, visit the accident site at the time of day commensurate with
the accident time and under the same conditions. Doing so gives the
investigators a more accurate picture of the existing environmental
CH 7

conditions at the time of the accident (glare, traffic, road conditions,

etc.). These observations should be recorded in notes, diagrams and
photographs so that investigators avoid relying on their memories.
CH 8 CH 9 CH 10

(2) Witness Interviews. Although witness interviews provide

insightful information, witness recollection rapidly deteriorates and can
be inadvertently tainted through media exposure and from comparing
stories with other witnesses. Statements taken from witnesses located
immediately after the accident are more reliable. To ensure witness
statements are accurate, detailed and as authentic as possible, witness
interviews are given a high priority. (See DA PAM Paragraph 2-3 for
interview techniques)

2-3
 (3) Command Data. Command factors at all levels are evaluated to
determine if command influence or lack thereof, contributed to the
cause of the accident or could play a role in preventing future accidents.
Collecting both documentary and verbal evidence helps investigators
determine whether personnel in the organization had knowledge of the
policies and procedures as well as the organization’s enforcement of
policies and procedures. Risk management is assessed with respect to
the accident under investigation. Determine what decisions were made
which may have “set up” the accident and the authority level of the
CH 1 CH 2

person making that decision, starting from the accident itself back (to
include DA level decisions, if appropriate).

(4) Environmental Data. Data pertaining to environmental

conditions (at the time of the accident) is collected to evaluate its
impact or influence on the performance of the individuals and/or
equipment involved. Environmental conditions include terrain, noise,
electromagnetic effects (E3), lighting, glare, space, quality of air, lunar
illumination (moonrise/moonset) for night or NVG missions, IR crossover
times for FLIR and weather/meteorological (humidity, pressure,
temperature, wind and illumination) conditions. To determine if an
environmental factor should be assessed as a causal factor, the central
questions to ask are: did this factor adversely influence human and/or
equipment performance and was the environmental element unknown
or unavoidable at the time of the accident? (See DA PAM 385-40,
Paragraph 2-6)

(5) Materiel Data. Collect data necessary to evaluate the performance

and survivability of the vehicle, aircraft, equipment (including life
support equipment (LSE) and protective equipment), buildings, and or
other support materiel. At a minimum, collect data from the historical
records for the past six months such as work orders, modification
work orders, services and periodic inspection records, as well as other
relevant records.

NOTE: For the purpose of accident classification any component

failure resulting from maintenance procedures performed prior to the
Army taking possession of the aircraft is considered a materiel failure
accident. Any component failure resulting from maintenance procedures
performed after the Army takes possession of the aircraft is considered a
human error accident.

(6) Personnel Data. Gather data that provides insight into the
performance, health, qualification and training of the individuals

2-4
involved in the accident. Those individuals include those directly
involved, those who influenced the operation, and those suspected to
have a role in the accident. Sources of information include, but are not
limited to individual records, interviews, and autopsy/medical records.

CH 1 CH 2
2-3. ANALYSIS. (See DA PAM 385-40, Paragraph 2-8)
a. General. The board conducts a systematic analysis of data collected
during the investigation to determine causes and develop findings
and recommendations. Findings and recommendations are derived
from the board’s analysis and deliberations. With few exceptions (for
example, insufficient data to make conclusive findings), findings and
recommendations are directly supported by the analysis of data. It
is acknowledged that informal analysis occurs throughout the data

CH 3 CH 4
collection phase as investigators pursue information. However, formal
analysis begins when the board president determines sufficient data has
been collected for the board to arrive at findings and recommendations.

b. Purpose. Analysis can be accomplished in many ways. Often the

board reviews collected data to ensure it is accurate and complete. This
may then be followed by individual, group teams (materiel/human/
environmental), or board level discussions of the data. This is designed
to ensure all data is placed in its appropriate area (human/materiel/

CH 5 CH 6
environmental) within the investigation. The end state of analysis is
to first provide all group members a full understanding of the facts
and circumstances surrounding the accident. It is also used to prepare
for deliberations and ensure the completeness of the investigative
process. This phase of the investigation may be formal or informal, but
is accomplished to ensure deliberations proceed without jeopardizing
the quality of the board’s findings and recommendations. It is during
this process that the board president ensures the analysis portion of
CH 7

the preliminary report is complete and contains all factual information

surrounding each identified anomaly.

c. Methodology. The “what happened” (mistake/error, environmental

factor, materiel failure) is often clear. The “why it happened” (system
CH 8 CH 9 CH 10

inadequacy/root cause) is usually more complex and difficult

to determine. The reasons people make errors, materiel fails,
environmental factors contribute, or injuries occur in an accident are
the keys to accident prevention. It is also likely that a combination of
active and latent failures contributed. Identification of latent failures
can be particularly challenging. A structured and meticulous analysis of
the data provides the best opportunity for the board to reach accurate
conclusions. Analysis can be accomplished in many ways. The following
is a standard method used during analysis:
2-5
 (1) Establish a chronology. The board develops two timelines.
The first, a macro timeline includes significant training events, unit
milestones, and other activities that could have led to a cultural or
latent error. The second, a micro timeline identifies critical time stamps
that involved the accident equipment, personnel and mission. These
timelines allow the board to analyze policies and events in the proper
context and weigh the role each played in the resulting accident.

(2) Identify Contributing Factors. Examine environmental conditions,

CH 1 CH 2

materiel failure, and human factors that caused or contributed to the

accident. Continually ask the question “why” until you have identified
all the contributing factors that led to an error, failure, or mistake.

(3) Review Anomalies. Anomalies are a deviation from the normal

or common order or from a rule. Anomalies can be positive events as
well as negative events. List all anomalies and group by environmental,
materiel, and human factors. (This is done periodically throughout
all phases of the investigation and recorded by each member in their
investigative notes.)

(4) Evaluate Anomalies. Evaluate anomalies as to their relationship to

the accident to determine mistakes, materiel failures and environmental
influences. Through this process each factual piece of data needs to be
continually analyzed and placed in its appropriate category. Additionally,
as new information is collected some anomalies are deleted as
insignificant or explained. The important part is to capture all the
anomalies, no matter if they seem insignificant, until a determination
can be made.

(5) Determine Root Causes. The last part of analysis is conducted

during deliberations. Remaining anomalies are categorized into
task errors and the reasons for the errors are identified by system
inadequacies (root causes) for the mistake, materiel failure and/or
environmental influences.

2-4. DELIBERATIONS.
a. General. Deliberations are the final stage of analysis and result in
the development of findings and recommendations. Deliberations are
conducted to:

(1) Identify mistakes/errors, materiel failures, environmental factors

(what happened).

(2) Identify root causes (why it happened).

2-6
 (3) Develop recommendations (what to do about it).

b. Preparation. The facility used to conduct the deliberations and

analysis should be secure, free from distractions, and allow for complete
privacy. The board president and recorder are the key personnel to

CH 1 CH 2
facilitate and record the analysis and deliberations. It is important that
all board members review witness statements, unit and Army-level
documents pertinent to the operation, as well as equipment, training
and medical records, and note any anomalies. Board members should
review their notes as well as Paragraph 2-8 of DA Pam 385-40 prior to
the analysis and deliberation session.

The president chairs the meetings and guides the proceedings. The

CH 3 CH 4
recorder ensures the products (timelines, anomalies) are posted in such
a manner that all board members can see them. All relevant information
remains readily accessible. The recorder also prepares charts prior to
beginning deliberations to capture the findings and recommendations as
the board reaches its conclusions. Each board member reviews and has
on hand a list of task error and system inadequacy codes (Appendix B
from DA PAM 385-40) prior to conducting deliberations.

c. Conduct of Deliberations. Deliberations are a formalized process

CH 5 CH 6
by which members of the board agree upon the resulting findings and
recommendations of an accident. The findings and recommendations
are the enduring foundation of the investigation and are the mitigating
tools to prevent future accidents. Each member provides input to each
finding and assists in the development of recommendations. The board
president may opt to conduct a vote to ensure that a majority of the
board members agree on a finding and that the task error and system
inadequacies correctly describe the circumstances of the accident. It
CH 7

is important that each board member participate to the fullest extent

possible and arrives to deliberations with a full understanding of the
facts associated with the accident.
CH 8 CH 9 CH 10

2-5. PRELIMINARY REPORT.

a. General. The narrative of the investigation consists of four sections:
history of events/flight, human factors, materiel factors, and analysis.
Two of these sections are required in the preliminary report: history of
events/flight and analysis. The history contains factual data only while
the analysis is reserved for the board’s documentation of its conclusions,
suspicions and opinions concerning the accident cause relationships.

2-7
 b. History of Events/Flight. The history presents a sequential snapshot
of the activities and events of the mission leading up to the accident,
the accident, and the immediate actions following the accident. The
timeline established during the investigation assists in writing this
paragraph. It includes enough detail to give the reader an accurate
description of events. Typical errors in this section include not clearly
identifying the units involved, not detailing the planning in preparation
for the mission, including analytical statements, and including findings.
Writers of this paragraph, normally the board president, include only
CH 1 CH 2

statements of fact.

NOTE: Names of the individuals are used in the history; however names
are not to be used in the analysis or findings.

c. Analysis. The analysis is the documentation of board deliberations.

It clearly shows the cause and effect relationship of the evidence
gathered during the accident investigation. Not only does the analysis
show clear cause and effect of an accident, but also eliminates plausible
accident causes the board determined did not cause or contribute to the
accident. In comparison to the findings, the analysis presents all relevant
data as the basis of the findings and recommendations.

CHAPTER 3
Board President
3-1. GENERAL. (See DA PAM 385-40, Paragraph 2-1)

CH 1 CH 2
a. The duties and responsibilities of the president of an accident
investigation board include, but are not limited to the following:

(1) Manage the investigation IAW DA PAM 385-40.

(2) Convene the board at the earliest possible time.

(3) Organize the board and assign areas of investigative responsibility

to each member.

CH 3 CH 4
(4) Take control of the accident site after the area is declared safe for
entry.

(5) Verify that adequate guards are on site to ensure the preservation
of evidence.

(6) Coordinate for equipment necessary to conduct the investigation.

CH 5 CH 6
(7) Dispatch board members to perform their duties and
responsibilities.

(8) Request additional technical assistance as required.

(9) Ensure all pertinent data is gathered before closing the field portion
of the investigation.

(10) After coordination with the collateral board, authorize recovery

CH 7

of the wreckage from the accident site when the field examination is
complete. Release wreckage/equipment for disposition to the owning
organization when the investigation is completed.

(11) Conduct frequent meetings of the board to update progress,

CH 8 CH 9 CH 10

exchange information and adjust assignments as necessary.

(12) Ensure accident information is released only to appropriate

authorities (i.e., appropriate command, staff, safety and investigation
personnel).

(13) Advise appropriate safety and public affairs officers to contact

local legal advisors in cases involving potential claims against the U.S.
government for personal injury or property damage.

3-1
 (14) Ensure data is correctly analyzed and conclusions are supported
by evidence.

(15) Ensure suitable recommendations are made and that a thorough

and accurate report is completed and submitted IAW AR 385-10 and DA
PAM 385-10.

(16) If applicable, coordinate with the local Criminal Investigation

Division (CID).

(17) Write the history of events/flight, analysis, findings and

recommendations for the technical report.

b. Backwards planning. Before meeting with the board, prepare a

CH 3

timeline. The timeline is crucial, because it helps identify benchmarks

that otherwise may not be noted without its preparation.

c. Daily meetings. Normally there is a morning and afternoon board

meeting. These meetings are a tool for the board president to create
shared understanding with the board, manage daily assignments, and
record/discuss anomalies discovered by the board. The time selected
for the meetings are synced with the accident unit’s beginning and end
of the duty day. As a technique, one of these meetings can be used to
meet with the unit point of contact in order to schedule interviews and
request data.

3-2. COLLECTION MANAGMENT.

a. Data collection. Crucial to any investigation is the gathering of
data/physical evidence. METT-T analysis determines the level of detail
collected in a combat zone. The data collected during an accident
investigation becomes the very basis of the accident investigation
board’s analyses and conclusions. To ensure a thorough effort is made
to collect all relevant data, the board president provides guidance and
direction on data collection during the Board’s daily meetings.

b. Data release. The board president authorizes the release of factual

information to individuals that are not board members (See AR 385-10
Paragraphs 3-27 through 3-31).

c. Data collected during an investigation include:

(1) Physical evidence - Matter related to the accident such as

equipment, parts, debris, hardware, voice recorders and other physical
items.

3-2
 (2) Verbal evidence - Witness statements and observations.

(3) Documentary evidence - Paper and electronic information, such as

records, reports, policies and procedures, photographs, videos, accident
site graphs, duty logs, board proceedings and notes, board member

CH 1 CH 2
notes, etc.

(4) Recording of anomalies – Through the course of collecting data

and evidence there are those factors uncovered by the board that
deviate from the norm or expectations. The board immediately records
these anomalies for discussion and analysis during this phase of the
investigation.

3-3. PRELIMINARY REPORT.

CH 3 CH 4
a. Narrative. The narrative of the investigation consists of four
sections: history of events/flight, human factors, materiel factors and
analysis. Two of these sections are written by the board president and
required in the preliminary report: history of events/flight and analysis.
Outlines for these sections are presented below. The history contains
factual data while the analysis is reserved for the board’s conclusions,
suspicions and opinions, concerning the accident cause relationships.
Additionally, the board president is responsible for writing the findings

CH 5 CH 6
and recommendations of the board.

b. History of Events/Flight. This paragraph presents a sequential

snapshot of the activities and events of the mission leading up to the
accident, the accident and the immediate actions following the accident.
Only include factual information in this paragraph. The timeline
established during the investigation assists in writing this paragraph.
It includes enough detail to give the reader an accurate description of
CH 7

events. Typical errors in this paragraph include not clearly identifying the
units involved, not detailing the planning in preparation for the mission,
including analytical statements, and including findings. Names of the
individuals may be used in the history; however names are not to be
used in the analysis. Below is an outline of the information included in
CH 8 CH 9 CH 10

the history of events/flight:

History of Events/Flight Outline

a. Pre-accident phase
- type of mission, activity or event (task and purpose)
- how the organization became tasked with the mission
- who authorized the mission
- individual(s) involved in the accident/injury or occupational illness

3-3
 - individual’s duty, unit/organization assigned
- how personnel were selected for the mission
- how they were selected for and informed of the mission, activity or
event
- actions of the personnel involved in preparing for the mission,
activity or event to include planning, application of RM, orders, and/or
briefings
- vehicle/equipment/vessel/structure involved, to include type, serial/
lot numbers, inspections conducted and the dispatching process
- Describe facts which may indicate whether or not an undue sense of
urgency was associated with the mission, activity, or event and if there
were any delays prior to the onset of the operation
CH 3

b. Accident phase.
- when the vehicle/personnel departed on the mission, activity or
event, and continue until the accident occurred
- if the mission, activity or event involved more than one routine
segment, requiring multiple activities, functions, or stops before the
accident occurred, concisely summarize these events until addressing
the segment involving the accident
- if the segment involving the accident contained an emergency:
• where and when it occurred/onset of the emergency occurred
• symptoms
• warnings, indications and instrument readings.
- describe actions/reactions of the personnel between the time of the
emergency and its conclusion.

c. Post-accident phase.
- describe the condition of the equipment/vehicle/structure/vessel,
to include whether or not the equipment was still operating and the
condition of personnel immediately after the accident. Reserve details
of damage to various equipment/vehicle/structure components for the
materiel factors portion of the narrative.
- if a post accident fire occurred, so indicate and explain how and
when it was extinguished, if applicable
- describe how the accident site was located
- summarize rescue and first-aid efforts, to include:
• who notified rescue/medical/police of accident
• response time
• type of equipment used in the evacuation
• who administered first aid/cardiopulmonary resuscitation and their
medical qualifications

3-4
 - briefly summarize:
• egress of occupants from vehicle/equipment
• time of arrival at the medical facility
• medical facility providing treatment
• time of death, if applicable

CH 1 CH 2
• Reserve details of the egress, rescue and evacuation for rescue
operations portion of the narrative

c. Analysis. This paragraph clearly shows the cause and effect

relationship of the evidence gathered during the accident investigation.
Not only does the analysis show the clear cause and effect relationship
of the accident, but it also eliminates plausible accident causes the
board determined did not cause or contribute to the accident. Below

CH 3 CH 4
are outlines of the required sections of the analysis paragraph for both
aviation and ground investigations:

 d. Analysis Paragraph Directions. Before starting the sub-paragraphs
of the analysis, begin the paragraph by specifying the scope and
conclusions of the investigation. In all cases, begin the paragraph with
the words: “After analyzing the human, materiel and environmental data
collected during the investigation, the board concluded the accident
was caused by ….” complete the sentence specifying the factors (human,
materiel, environmental) that caused the accident.

(1) Accident Sequence. Include a description of the accident that

includes the board’s estimate of how the accident occurred. This
paragraph creates a picture in the reader’s mind of how the aircraft
crashed or how the vehicle rolled over, etc. It is not a repeat of the
history, but includes details of the accident dynamics. Include the
CH 3

board’s analysis of how and why the accident happened as it did.

(2) Environmental Factors. Include meteorological and non-

meteorological factors. Use the key words under Table B-4 of DA PAM
385-40, describing the environmental phenomena present during the
accident when applicable, along with the results. Environmental factors
can be present at the time of the accident but not be causal. There can
be no present and contributing finding against environmental factors if
the board concludes they were not causal.

(3) Materiel Factors. This sub-paragraph includes all materiel

factors. Use the key words under Table B-3 of DA PAM 385-40 to
describe what happened to a particular part, piece of equipment,
system, or component. Refer to reports written by board advisors,
like manufacturer representatives. Develop a separate paragraph for
each major component or system. Each statement of materiel failure is
followed by the cause of the failure. Also describe the consequences of
the failure and identify the part number or NSN of the part that failed.
Explain why the board ruled out a part, system, or component that could
have caused the mishap. Design or maintenance issues that originated
or occurred at the manufacturer are considered materiel issues.

(4) Human Factors. This sub-paragraph includes all human factors.

Use the key words on Table B-5 of DA PAM 385-40 to describe issues
associated with each of the human factors system inadequacies/
root causes. Develop a separate paragraph for each of the basic root
causes/system inadequacies and discuss the result of the deficiency. In
each case, develop analytical statements and then support them with
statements of fact.

3-6
 a. Support. Describe issues relating to resourcing, facilities, services,
equipment (design-induced error, etc.), numbers of personnel and other
support type factors.

b. Standards. Describe the adequacy of written guidance for a

CH 1 CH 2
particular task. All findings refer to a standard of some type. Be sure
to explain any standards shortcomings and the consequences of those
shortcomings. If the board concluded all documents were adequate,
explain it that way. The presence of a standard in an Army publication
suffices as a standard if not included in the unit SOP. Not restating the
standard from the Army publication in the unit SOP is not a shortcoming.

c. Training. Describe the training an individual may have received

CH 3 CH 4
either in an MOS-producing school, unit, or other. A Soldier without
adequate experience or with some sort of negative habit transfer
is considered to have a training deficit. For other than active duty
Army Soldiers, i.e. National Guard, or other service soldiers, discuss
mobilization or familiarization training.

d. Leader/Command.
-Leader Factors. Describe what an individual did in his or her
capacity as a leader. Table B-5, DA PAM 385-40 discusses leader failure

CH 5 CH 6
as a lack of supervision, but also consider it a leader issue when a leader
chose not to enforce a standard, did not make an informed decision, or
was not where he or she should have been.
-Command Factors. Assess the influence of command activity, or
lack thereof, in relation to the accident. Apply the risk management
5-step process. Look at each decision point in the accident sequence of
events (from pre-mission planning to the actions immediately following
the accident) and the authority level of the person making that decision.
CH 7

The goal is to determine if informed decisions were made at the

appropriate level of authority.

e. Individual. Discuss the board’s conclusions relative to an individual

CH 8 CH 9 CH 10

Soldier in terms of the error or the indiscipline that caused the accident
or permitted the Soldier to make the error, along with the results of his/
her actions. Include the injuries to the Soldier in the results portion of
the discussion. Although each injury does not need its own paragraph,
injuries which are the result of an anomaly are described.

(5) Other. In this paragraph include special observations (i.e., factors

that in no way contributed to the accident but identify local conditions
or practices that should be corrected).

3-7
 NOTE: If a potential safety issue has Armywide implications, making the
finding a PBNC rather than a special observation ensures the problem
has visibility above the accident unit level.

3-4. FINDINGS & RECOMMENDATIONS.

a. General. Finding and recommendations are formulated during
deliberations. Each finding is substantiated in the analysis paragraph
of the report narrative. Immediately following the finding, the
recommendations are written. Recommendations answer the question,
“what to do about it?” The recommendations target the root causes/
system inadequacies.

b. Findings. DA Pam 385-40 groups findings into four categories:

CH 3

present and contributing, present but not contributing, present and

contributing to the severity of injury/extent of property damage and
suspected present and contributing. The most common error in an
accident investigation report is an improperly written present and
contributing finding. Present and contributing findings are an integral
part of the accident reporting process and are imperative in identifying
the task errors (what happened) and system inadequacies (why it
happened). If the findings’ author does not clearly identify “why”
the accident occurred he/she cannot formulate properly directed
recommendations (what to do about it) addressing the root cause of the
accident. There are three accident causal factors: human error, materiel
failure and environmental factors. Present and contributing findings
must be written using the elements described in DA Pam 385-40. For an
aviation accident, use the instructions for DA Form 2397-2 and Table 3-1.
For ground accidents, use the instructions for block 65 of the DA Form
285 found in Paragraph 4-3. The elements of a present and contributing
finding give the investigator a standardized way to present the finding.

(1) Elements of a Present and Contributing Finding:

Element 1: An explanation of when and where the error, materiel
failure, or environmental factor occurred in the context of the accident
sequence of events; e.g., “during preflight,” “during takeoff,” “while
employing,” etc.

Element 2: Identification of the individual involved by duty

position; or the name and part number (PN) or national stock number
(NSN) of the part, component, or system that failed; or a description of
the environmental factor, as appropriate.

Element 3: For human error, identification of the task or function

the individual was performing and an explanation of how it was
3-8
performed improperly. Refer to DA PAM 385-40, Appendix B, Table
B-1 for task error categories. The error could be one of commission
or omission, e.g., an individual performed the wrong task, incorrectly
performed the correct task, or failed to perform a required task or
function. In the case of a materiel failure, identify the mode of failure;

CH 1 CH 2
e.g., corroded, burst, twisted, decayed, etc., refer to Appendix B, Table
B-3 and for environmental conditions see Table B-4. NOTE: Identify only
one task error per finding.

Element 4: Identification of the directive, i.e., ATM, SOP, FM or

common practice governing the performance of the task or function. In
lieu of a written directive, the error may represent performance that is
contrary to common practice.

CH 3 CH 4
Element 5: An explanation of the consequences of the error,
materiel failure, or environmental effect. An error may directly result in
damage to equipment or injury/occupational illness to personnel, or it
may indirectly lead to the same end result. A materiel failure may have
an immediate effect on equipment or its performance, or it may create
circumstances that cause errors resulting in further damage/injury or
occupational illness inevitable.

CH 5 CH 6
Element 6: Identification of the reasons (system inadequacy(ies))
the human, materiel, environmental conditions contributed to the
accident. Refer to the list and examples of system inadequacy(ies)
provided in DA PAM 385-40, Appendix B, Table B-5. NOTE: The finding
may contain multiple system inadequacies (training, individual, leader,
etc.).

Element 7: A brief explanation of how each reason contributed to

CH 7

the error, materiel failure, or environmental factor.

Present and contributing human error findings contain at a minimum

the seven elements of information identified above. The first five
elements relate to the task error, with element six and seven identifying
CH 8 CH 9 CH 10

the system inadequacies. Materiel failure and environmental factors

basically contain the same elements as human error finding with a few
differences. DA Form 285 ground accident report follows the same
element requirements as the aircraft accident report.

Human Error - When writing a present and contributing human error

finding the two most important elements are the task error (element
3 above) and the system inadequacy (element 6 above). These two
elements define the root cause of the accident. The aviation (UAS
3-9
 included) human task errors are located in DA Pam 385-40, Appendix
B-1 and the ground task errors in Appendix B-2. When writing a present
and contributing human error finding, use only one of the individual task
errors. It is not a requirement to use the exact wording of the task error
in a particular finding, but if there is any doubt which task error you are
trying to describe, use its basic descriptor, e.g., failed to properly scan
(Code P01) or improper use of equipment (Code 06). Again, you may
only use one task error per finding.

The most overlooked element in a present and contributing finding is

the system inadequacy (element 6 above). Common to both aviation
and ground accidents, the system inadequacy is an essential element
of the finding because it tells why the individual made the mistake. If
CH 3

an individual failed to scan which is a task error, why did he/she fail
to scan? One of the five system inadequacies answers that question:
leader, training, standards, support and individual. As in the task
error above, it is not a requirement to use the exact wording of the
system inadequacy in a finding, but if there is any doubt which system
inadequacy you are trying to describe, use the system inadequacy’s
basic descriptor, e.g., overconfidence in abilities (Code 16). you may
only use one task error per finding but the use of multiple system
inadequacies in a single finding is acceptable if more than one system
inadequacy identifies why the individual made the mistake.

NOTE: For Class A and B accidents substantiate the findings by analysis,

as described in the completion instructions for the DA Form 2397-3
and the DA Form 285 Paragraph 4-4. Manned aircraft Class C, aircraft
ground A/B and UAS accidents do not require a formal analysis, support
the findings by entering a concise summary of events from the initial
onset of the emergency until the aircraft is at rest, to include injuries
resulting from the accident. Specify and discuss in the narrative of the
summary the actual error/failure/effects and the root causes to support
the present and contributing finding(s).

(2) Human Error System Inadequacy Definitions:

Leader Failure - This occurs when leaders fail to monitor mission

execution and planning, correct inappropriate behavior, take appropriate
action or emphasize correct procedures that allowed subordinates to
commit task errors or results in a materiel failure. A leader failure cause
factor is identified by the leader failure system inadequacy (element 6)
not by the leader/supervisory errors identified in the (element 3).

3-10
NOTE: A leader failure system inadequacy does not identify why the
leader failed. The leader failure system inadequacy explains a leader’s
lack of supervision that allowed a subordinate to make a mistake. If a
finding includes a leader failure system inadequacy there is a follow-on

CH 1 CH 2
finding on that leader describing how a leader fails to properly supervise
a subordinate (see example findings).

Training Failure - This occurs when training is incorrect, incomplete or

insufficient for an individual to perform a task to standard. A common
mistake is to identify inexperience as an individual failure when DA Pam
385-40, Table B-5, identifies inexperience as a training failure.

Standards Failure - This occurs when standards do not exist or they are

CH 3 CH 4
unclear, impractical, or inadequate. Failure to follow an established
standard does not constitute a standards failure.

Support Failure - This occurs when the type, amount, capabilities,

condition of the support is insufficient to correctly perform the mission.
Support includes personnel, equipment, materiel, supplies, services,
or facilities. A piece of equipment that fails because the mechanic did
not service it properly because the proper tools were not available
would not be a materiel failure. The piece of equipment failed because

CH 5 CH 6
of human error: support failure. Additionally, if an individual makes
an accident causing mistake due to the way a piece of equipment is
manufactured or designed, the finding would be classified as a human
error on the individual that made the mistake with a support failure
system Inadequacy. A support failure due to inadequate/improper
design (Code 11) would be when an operator intended to use a switch
and its location, size, shape, method, or operation is similar to another
switch with a different function. The mere failure of a component or
CH 7

part due to design or manufacture is not a support failure (see materiel

failure).

Individual Failure - This occurs when the individual knows the standard
CH 8 CH 9 CH 10

and is trained to standard but elected not to follow the standard.

(3) Elements of a Present and Contributing Materiel Failure Finding:

1. Explanation of when and where the materiel failure/malfunction

occurred in the context of the accident sequence of events.

2. Name and part number (PN) or national stock number (NSN) of the
part, component or system that failed.

3. Mode of failure (corroded, burst, twisted, decayed, etc.)(see DA

PAM 385-40, Appendix B, Table B-3 for definitions and examples) NOTE:
only one task error failure per finding.

4. Consequences of the materiel failure.

5. Identification of reasons (root causes/system inadequacies) materiel

failure/malfunction caused or contributed to accident. NOTE: The
finding may contain multiple system inadequacies (design, manufacture,
etc.)

6. Brief explanation of how each reason (root cause/system

inadequacy) contributed to the materiel failure/malfunction.

Materiel failure and malfunction causes/system inadequacies. The

identification of a materiel failure is of little value until “why” the
failure occurred is determined. After the “why” is determined, develop
corrective measures to elevate or implement controls reducing the
possibility of recurrence. Identify materiel failures/malfunctions in
terms of one or more system inadequacy(ies). DA Pam 385-40 defines
materiel system inadequacy as a tangible or intangible element that did
3-14
not operate to design specifications and caused, allowed, or contributed
to a materiel failure or malfunction. The system inadequacies
associated with materiel failure are design, manufacturer, fair wear and
tear (FWT) and maintenance applicable to both aviation and ground
accidents.

CH 1 CH 2

Design. Equipment design becomes an issue when equipment failure
occurs because of inadequate design specifications. A design issue
may be the result of inadequate materiel composition, equipment size,
shape, location, or operational characteristics opposite to common
practice operation. Accident investigators often overlook design
influence on human performance resulting in accidents. Evaluate all
possible design issues in order to implement corrective measures.

CH 3 CH 4

Manufacture. Equipment manufacture becomes an issue when the
failure results from equipment development processes not conforming
to design specifications. A manufacture issue may be the result of using
substandard material, improper assembly, or other anomalies occurring
during the manufacturing process.

Fair, Wear and Tear (FWT). FWT becomes an issue when equipment
fails due to use. Any item of equipment exposed to a repetitive motion

CH 5 CH 6
is subject to failure. FWT can occur in conditional items as well as time
between overhaul/change items.

Maintenance. Maintenance becomes an issue when failure or
malfunction occurs because of improper maintenance or lack of
maintenance. When the Army does not have control or oversight of the
maintenance operation and improper maintenance caused the accident,
write a materiel failure finding. When the Army exercises control of
CH 7

the maintenance operation, classify materiel failures due to improper

maintenance as human errors and document them as a human error
finding.

CH 8 CH 9 CH 10

NOTE: For Class A and B accidents, substantiate all findings by an

analysis, as described in the completion instructions for the DA Form
2397-3 and Paragraph 4-4 for the DA Form 285. Manned aircraft Class C,
aircraft ground A/B and UAS accidents do not require a formal analysis,
support the findings by entering a concise summary of events from
the initial onset of the emergency until the aircraft is at rest, to include
injuries resulting from the accident. Specify and discuss in the narrative

1. Explanation of when and where the environmental factor occurred in
the context of the accident sequence of events.

CH 5 CH 6
2. Aircraft and, if applicable, the individual(s) involved by duty position.

4. Consequences of environmental effect.

5. Explanation/identification of reason(s) environmental conditions

CH 7

Environmental factors are those environmental elements or conditions

such as noise, illumination, space and weather conditions (For example,
precipitation, temperature, humidity, pressure, wind and lightning)
CH 8 CH 9 CH 10

having an adverse effect on the performance of the individual or

equipment so that an accident results or could result. Assessment of
environmental elements (For example, contaminants, noise, vibration,
artificial illumination, acceleration, deceleration, radiation, adequacy
of work surface/space and weather conditions) is accomplished to
determine their influence on human and/or materiel performance.
Contaminants (fumes, chemicals) can lead to respiratory problems;
noise (radio static, engine and transmission noise) can distract attention,
interfere with effective communications and lead to fatigue.

 Inadequate illumination can cause reduced visibility. Inadequate
work space (cluttered, poorly designed driver compartment) can
contribute to procedural errors or limit outside visibility. Knowledge of
environmental elements does not eliminate them as factors influencing
errors, injuries, or failures.
NOTE: To determine if an environmental factor should be assessed
as a causal factor, the central questions to ask are: did this factor
adversely influence human and/or equipment performance and was
the environmental element unknown or unavoidable at the time of
the accident/injury/occupational illness? Environmental factors can
be divided into those which could not have been avoided, and those
which could have been avoided or precautions implemented to reduce
CH 3

or eliminate its adverse effects on personnel and/or equipment. An

environmental deficiency is not assessed as a causal factor if it was
known and could have been avoided before the accident.

NOTE: For Class A and B accidents, all findings are substantiated in
the analysis, as described in the completion instructions for the DA
Form 2397-3 and Paragraph 4-4 for the DA Form 285. Manned aircraft
Class C, aircraft ground A/B and UAS accidents do not require a formal
analysis but is supported by entering a concise summary of events from
the initial onset of the emergency until the aircraft is at rest, to include
injuries resulting from the accident. The actual error/failure/effects
and the root causes are specified and discussed in the narrative of the

CH 5 CH 6
summary in order to support the present and contributing finding(s).

(5) Example Aviation Present and Contributing Findings and

Recommendations with Multiple System Inadequacies
You may combine multiple system inadequacies in one finding, but
only one task error per finding. Please note that a leader failure in the
second paragraph below (system inadequacy paragraph) requires an
additional present and contributing finding on why the leader failed to
CH 7

properly supervise the subordinate. (See findings 1 and 2 below)

FINDING 1 (Present and Contributing: Human Error – Training,

Individual and Leader Failure):
CH 8 CH 9 CH 10

While executing an approach to an unimproved LZ in mountainous

terrain in a heavily loaded UH-60L, the pilot (PI), on the flight controls,
did not recognize the hazardous conditions. That is, the PI failed to
recognize the conditions produced by the combined effects of high gross
weight and tail winds at the higher altitude. The PI did not recognize the
critical condition and execute a go-around as required by TC 1-237, Task
1058, before he lost control of the aircraft. As a result, the aircraft main
rotor RPM drooped and the aircraft crashed. The aircraft was severely
damaged and two crew members sustained minor injuries.
3-19
 The board concluded the PI’s actions were a result of his lack of
experience operating in this type of environment and overconfidence
in his ability to operate in that environment. The PI had executed
similar approaches to this LZ days prior to the accident, but not with the
conditions present during the accident. The board also concluded the
PI’s actions were due to improper supervision by the pilot in command
(PC).
RECOMMENDATION 1:
a. Unit Level Action: Commander, 1-999th Avn Regt, during simulator
periods ensure a scenario is developed and instituted that replicates the
high power demands required during mountainous approaches with full
CEFS tanks on. Further, develop the scenario to rehearse circumstance
CH 3

where jettisoning the CEFS is the most logical outcome to avoid an

accident. This will give crews the experience in what effect jettisoning
the CEFS will have on the aircraft.

b. Higher Level Action: None.

c. Army Level Action: None.

NOTE: The following finding (Finding 2) is the result of finding 1 above

identifying why the leader (pilot in command) contributed to the pilot’s
error.

FINDING 2 (Present and Contributing: Human Error – Individual and

Training Failure):
While preparing to land in an unimproved mountainous LZ in a heavily
loaded UH-60L, the PC did not properly conduct in-flight planning. That
is, the PC did not modify the approach and landing plan based on the
environmental conditions IAW Training Circular (TC) 1-237, Task 1058,
Perform Visual Meteorological Conditions Approach. The PC did not
use the tabular data or evaluate the winds accurately. As a result, as
the PI executed the approach, the aircraft’s main rotor drooped and
the aircraft crashed. The aircraft was severely damaged and two crew
members sustained minor injuries.
The board concluded the PC’s actions were a result of his
overconfidence in the pilot’s (PI) ability to safely conduct the approach
and landing, his overconfidence in his ability to correct any error the
PI might make, and improper mountain training conducted by the unit
standardization instructor pilot.

3-20
RECOMMENDATION 2:
a. Unit Level Action: Commander, 1-999th Avn Regt, utilize High
Altitude Army Aviation Training Site, Mountain Training Course, and
trained instructor pilots, to serve as unit trainers to train other unit
instructor pilots on mountain, pinnacle, ridgeline and terrain flight in

CH 1 CH 2
mountainous environments.

b. Higher Level Action: Commander 999 CAB, forecast and fund one
slot per year to allow an instructor pilot from 1-999th Avn Regt to attend
the Army High Altitude Army Aviation Training Site approved Mountain
Flying Course.

c. Army Level Action: PEO-Avn, ensure tabular data in the operator’s

NOTE: When ‘leader’ is identified as a system inadequacy/root cause,
this leads to a second finding, in which case a mistake/error is assigned
to the leader/command and the root cause(s)/system inadequacy(ies) for
the mistake identified. When a finding is written on a leader/command,
it is important to determine why that mistake/error was made so that,

CH 1 CH 2
if necessary, the problem can be brought to the attention of senior
Army leadership. For example, if inadequate risk management is
identified, was it due to a support problem (lack of sufficient resources),
a standards problem, etc.

(6) Additional Example of a Ground Present and Contributing Finding

and Recommendations

FINDING 1 (Present and Contributing: Environmental):

While conducting a daytime interdiction mission, area reconnaissance
of the northwest Area of Operation (AO) Falcon, the third vehicle in a
three-vehicle patrol, an M1114 up-armored high mobility multipurpose
wheeled vehicle (HMMWV), rolled into an irrigation canal when the
road collapsed into the canal. That is, the board concluded that the road
was saturated with water due to three days of constant rain prior to the
day of the mission. When the roadway collapsed, the vehicle rolled into
the canal and came to rest inverted. As a result, one Soldier received
fatal injuries and the vehicle received significant damage.

The board determined that the driver’s actions did not cause or
contribute to the accident. The board concluded that the right side of
the road collapsed due to being saturated from previous days of heavy
rainfall. It is also possible that the other two vehicles weakened the
road to the point of collapsing.

RECOMMENDATION 1:
a. Unit Level Action: Commander, Company D, 2d Battalion, 9999th
Infantry Regiment, brief all assigned and attached personnel on the facts
and circumstances surrounding this accident. Emphasize the guidance
in GTA 55-03-030, GTA 55-03-031, and Safety of Use Message (SOUM)
050004 prior to all missions.

b. Higher Level Action: Commander, 2d Brigade Combat Team, brief

3-26
all assigned and attached personnel on the facts and circumstances
surrounding this accident. Emphasize the guidance in GTA 55-03-030,
GTA 55-03-031, and SOUM 050004 during these briefings. Recommend
usability surveys of all unimproved roads.

CH 1 CH 2
c. Army Level Action: Commander, U.S. Army Combat Readiness
Center, disseminate the facts and circumstances surrounding this
accident.
When to use a Suspected Present and Contributing Finding. A
suspected present and contributing finding is used when the accident
investigation board cannot positively determine or reasonably conclude
what caused the accident. In these cases, the board must develop a
hypothetical explanation for why an accident occurred. Using whatever

CH 3 CH 4
evidence is available, it is acceptable for the accident investigation
board to deduce that a certain event could have been or was the most
likely cause of the accident. The discussion in the analysis must be
very detailed and must discount any other plausible explanations of
why the accident occurred and support the cause the board suspects
actually caused the accident. For example, an aircraft is found crashed
in an area in which there were known to be thunderstorms around the
time of the accident, but the crew did not survive the accident and

CH 5 CH 6
there were no witnesses. Radar showed the aircraft was in vicinity of
the thunderstorm area, but not close to or in any storm at the time
of the accident. The impact appeared to have a significant vertical
component. Teardown analysis and records reviews show no problems
with the aircraft components or maintenance and the engine appeared
to be operating normally. All aircraft components were found to be
attached and appeared fully functional at impact. The board may
suspect the aircraft was involved in a downburst event, based on the
CH 7

physical evidence at the scene, the weather report and radar tracks of
thunderstorms in the vicinity, and the lack of any evidence indicating
otherwise.
Present and Contributing to the Severity of Injury/Extent of Property
CH 8 CH 9 CH 10

Damage. This type of finding covers factors that did not cause the
accident, but contributed to the severity of the injuries or extent
of damage. Personnel injuries attributable to defects in life support
equipment, personal protective clothing/equipment, or aircraft/vehicle
crashworthiness design should also be summarized as findings in this
category. These findings are written in the same format as the present
and contributing finding using the applicable elements for the three
causal factors (human, materiel and environmental). These findings are
preceded by the following statement.

the following statement.

THE FINDINGS LISTED BELOW DID NOT DIRECTLY CONTRIBUTE TO THE

CAUSAL FACTORS IN THIS ACCIDENT; HOWEVER, IF NOT CORRECTED,
CH 3

THEY COULD ADVERSELY AFFECT THE SAFETY OF FUTURE OPERATIONS.

FINDING 5 (Present But Not Contributing):

The accident crews failed to complete pre-mission planning

requirements by departing with an expired weather briefing void time.
The Accident Investigation Board investigating another recent CAB, 22ID,
accident noted that the accident crew also departed with an expired
weather briefing void time. Furthermore, the board reviewed flight
briefings for the week of 31 December 2005 through 5 January 2006
and noted that 74 flights took off with an expired weather briefing
void time. Although the board concluded that weather conditions did
not contribute to this accident, these uncorrected weather planning
deficiencies could jeopardize the safety of future flights.

RECOMMENDATION 5:
a. Unit Level Action: Commander, 1-22th Attack Reconnaissance
Battalion, Combat Aviation Brigade, 22th Infantry Division, enforce rules
and regulations regarding weather briefing requirements.

b. Higher Level Action: Commander, Combat Aviation Brigade, 22th

Infantry Division, enforce rules and regulations regarding weather
briefing requirements.

c. Army Level Action: None.

c. Recommendations. Each present and contributing finding is

followed by recommendations having the best potential for correcting
or eliminating the reasons (system inadequacy(ies)) for the error,
materiel failure, or environmental factor that caused or contributed to
the accident. Additionally, recommendations follow each finding that
3-28
was present but not contributing to the accident; i.e., a factor that could
adversely affect the safety of continued operations if left uncorrected.
Recommendations do not focus on punitive steps addressing an
individual’s failure in a particular case. To provide a broad application
at preventing accidents in the future, state recommendations in broad

CH 1 CH 2
terms. Refer to the list of remedial measures in DA PAM 385-40
Appendix B-6 for both ground and aviation accidents. The board should
not allow existing budgetary, materiel, or personnel restrictions to
influence their recommendations. In developing the recommendations,
view each recommendation in terms of its potential effectiveness.
For example, design improvement of a part that has a history of
recurring failure is a better solution than recommending procedures to
accommodate the deficiency. Direct each recommendation at the unit,

CH 3 CH 4
command, or activity having proponency for and which is best capable
of implementing the actions contained in the recommendation. The
actions required at “Unit Level” (company, troop, battalion), “Higher
Level” (brigade, division, corps, Army Headquarters), and “DA Level” (to
include Army Headquarters with Army-level proponency) is addressed
by each recommendation. If one or more of these three command
levels had no action requirement, a negative report is required. For
example, “DA Level Action: None.” (See example recommendations in

CH 5 CH 6
this document).

3-5. INTERNAL Board STAFFING. After completing the initial draft of the
board president’s portion of the report narrative, designate a time for
the board to carefully read the draft history, analysis, and findings and
recommendations. A suggested technique is to make separate copies
for all board members and allow them enough time to thoroughly read
the written product. The intent is to review the documents for clarity
and accuracy of content. An additional benefit is that the review also
CH 7

identifies major grammatical and spelling errors. Installation accident

investigation (IAI) board presidents may contact the USACRC G-3
operations at 334-255-2660/3410 (DSN: 558) to have investigators
assist the board with review of their products and provide advice on the
CH 8 CH 9 CH 10

presentation of their investigation material.

3-6. TERMINOLOGY. There is specific terminology used in the board

president’s part of the report narrative. The following terms and phrases
are not found in DA PAM 385-40, but are accepted terminology:
In contravention to – This phrase is used to convey deviation for a
published or well-known common practice. It is used in the analysis
paragraph and findings.

3-29
 Suspected - This term is used to convey the board was unable to
agree on the exact origin or cause, but the data indicates what or
why something happened. In these cases there may be more than
one plausible cause and the board suspected one more strongly than
another. In deliberations and analysis, the board takes a lot of time
to discount other plausible causes and to justify their final cause or
contributing factors. (Critical information is unavailable)

Concluded - This term is used to convey the board agreed the

preponderance of data is enough to judge what or why something
happened (analysis is required).

Determined - This term is used to convey, based on documented

CH 3

evidence, the board easily discovered and is resolute in what or why

something happened. There is typically a very clear cause and the board
is not obligated to discount other plausible causes. (The facts are self-
evident)

Habit Interference - An error is made because task performance was

interfered by:
a. The way the person usually performs similar tasks
b. The way the person performs the same task under different
conditions or with different equipment (e.g., a particular control is
operated in one direction for early models, but reversed in subsequent
models)

Negative habit transfer - Negative transfer of training; i.e., it is more

difficult to learn Task B as a result of having learned Task A.

CHAPTER 4
Board Recorder
(See DA PAM 385-40, Paragraph 2-1)

4-1. GENERAL.

CH 1 CH 2
a. USACRC-trained recorders are mandatory for all Centralized Accident
Investigations (CAI). The responsibilities and duties of the recorder are
as follows:

(1) Receive and administratively process data gathered by the

members of the board.

(2) Monitor report processing requirements and stages of completion.

CH 3 CH 4
(3) Assign tasks and monitor work of supporting clerical personnel.

(4) Ensure all necessary substantiating data are collected and posted to
the technical report.

(5) Assemble the final technical report.

(6) Ensure the human and materiel narrative of the technical report is
complete.

CH 5 CH 6
(7) Document the accident site (photographs & diagram).

(8) Review unit safety program and life support equipment (LSE)
program.

(9) Perform other duties as assigned by the board president.

4-2. DATA MANAGEMENT.

CH 7

a. The data collected during an accident investigation becomes the very

basis of the accident investigation board’s analyses and conclusions.
The board recorder is responsible for the disposition of all data acquired
during the investigation.
CH 8 CH 9 CH 10

b. Data and evidence collected during an investigation includes-

(1) Physical evidence - Matter related to the accident such as

equipment, parts, debris, hardware, voice recorders and other physical
items.

(2) Verbal evidence - Witness statements and observations.

(3) Documentary evidence - Paper and electronic information, such as

4-1
 records, reports, policies and procedures, photographs, videos, accident
site graphs, duty logs, board proceedings and notes, board member
notes, etc.

(4) Recording of anomalies – Through the course of collecting data and

evidence there are those factors uncovered by the board that deviate
from the norm or expectations. The board records these anomalies for
discussion and analysis during the analysis phase of the investigation.
Typically, boards record anomalies under the headings of environmental,
materiel and human factors.

c. The collection of data comes from six major areas-

(1) The Accident Site

(2) Witness Interviews

(3) Command Data

CH 1 CH 3 CH 4

(4) Environmental Data

(5) Materiel Data

(6) Personnel Data

d. Usually, the accident unit’s parent organization designated safety

representative initiates the gathering and preservation of data and
evidence. To ensure the appropriate measures are taken, the board
recorder requests the on-site safety representative to initiate the
gathering of data and evidence as outlined in Appendix A, POC checklist.
A copy of the checklist can be emailed or faxed to the designated safety
representative.

e. Once the board assembles at the accident location, the on-site safety
representative briefs the board on actions taken prior to the board’s
arrival. All data collected by the on-site safety representative is turned
over to the board recorder with the appropriate documentation.

f. Although the initial gathering of data begins with the on-site safety
representative, the majority of the data is collected by the board once
they assemble. Generally, the gathering of data is a simultaneous
effort by various work groups and is an ongoing process. Preliminary
evaluation of data by the board leads to subsequent data collection.

4-2
4-3. ACCIDENT SITE. (See DA PAM 385-40, Paragraph 2-2)
Evidence may be inadvertently moved, removed or destroyed, especially
if the situation does not permit preservation of the accident scene.
Therefore, the on-site safety representative, after recording initial
witness information and statements, develops a diagram of the accident

CH 1 CH 2
site/wreckage distribution. The site diagram captures the position of
debris, equipment, tools, body parts and injured persons.

a. It is imperative that all members of the board view the accident site
as soon as possible after being briefed in order to have a general mental
picture of what occurred. Consider the following issues before visiting
the site:

CH 3 CH 4
(1) If there is daylight left every effort should be made to visit the site.

(2) Consider whether or not the accident involved composite or other

hazardous materials and ensure the appropriate precautions are taken
prior to and while visiting the site.

(3) Check with the host organization’s designated representative to see

if any photographs, diagrams, videos or other pictorial representations

CH 5 CH 6
of the scene was collected and are available for viewing.

(4) When feasible, visit the accident site at the same time of day as
the accident and under the same conditions. Doing so will give the
investigators a more accurate picture of the existing environmental
conditions at the time of the accident (glare, traffic, road conditions,
etc.).
CH 7

(5) In the event of an accident on a public roadway and the scene has
been cleared away; investigators should maximize local resources such
as state, local, or military police reports and site diagrams.

b. Photographing the scene. The board recorder has the responsibility

CH 8 CH 9 CH 10

for ensuring that all necessary photographs are taken. If an installation

photographer is provided, the board member in charge of photography
should supervise him. Remember: It is always better to have too many
photos than not enough.

(1) A recommended photographic checklist is shown below:

- Aerial view from four directions (N, S, E, W)
- Ground view from four directions (N, S, E, W)

4-3
 - General overview of wreckage beginning at the nose and circling
site every 45 degrees
- Photographs of any ground scars
- Photographs of major components/controls/parts
- Instrument panel and consoles
- Cockpit/cabin/cab areas (include seats and restraining systems)
- Canopy
- Detailed photographs of suspected failed parts
- Disassembly of parts/equipment (if done)
- Other photographs deemed necessary

(2) As photographs are taken, a log should be completed noting the

scene/subject, date, time, direction, and orientation of photographs, as
well as the photographer’s name.

c. Inspecting physical evidence at the scene. After diagramming and

CH 1 CH 3 CH 4

photographic recording, a systematic inspection of physical evidence can

begin. The inspection involves-

(1) Survey the involved equipment, vehicles, structures, etc., to

ascertain whether there is any indication that component parts were
missing or out of place before the accident.

(2) Note the absence of any parts of guards, controls, or operating

indicators (instruments, position indicators, etc.) among the damaged or
remaining parts at the scene.

(3) Identify as soon as possible any equipment or parts that must

be cleaned prior to examination or testing and transfer them to a
laboratory or to the care of an expert experienced in appropriate testing
methodologies.

(4) Note the routing or movements of records that can later be traced
to find missing components.

d. These observations are recorded in notes, diagrams, and

photographs so that investigators avoid relying on their memories.
Some investigators find a small recorder useful in recording general
descriptions of appearance and damage; however, the potential failure
of a recorder and limitations of verbal description require their use in
conjunction with notes, diagrams and photographs.

4-4
 e. Before inspecting or removing physical evidence, follow these
guidelines:

(1) Obtain concurrence among board members before any wreckage or

equipment is moved or removed to ensure observations are complete.

CH 1 CH 2
However, final approval lies with the board president.

(2) Complete site documentation prior to removing or moving any

wreckage or equipment (measurements for maps, photographs and
video made).

(3) Be aware that the accident site may be unsafe due to hazardous
materials or weakened structures.

CH 3 CH 4
(4) Do not start recovery/removal until witnesses have been
interviewed, since visual reference to the accident site can stimulate
one’s memory.

(5) Mark locations of removed wreckage or equipment with spray

paint or wire-staffed marking flags. Annotate the marking flags to
identify wreckage or equipment that was removed and to allow later
measurement.

CH 5 CH 6
(6) Use care during recovery/removal and preliminary examination to
avoid defacing or distorting impact marks and fracture surfaces.

f. Following inspection of the scene, investigators may need to remove

items of physical evidence. To ensure the integrity of evidence for later
examination, the extraction of parts is controlled and methodical. Before
evidence is removed from the accident scene, it is carefully packaged
and clearly identified.
CH 7

(1) Equipment, parts or subassemblies thought to be defective,

damaged, or improperly assembled are removed from the accident
scene for technical examination. Document the removal using position
CH 8 CH 9 CH 10

maps/diagrams and photographs to display the part in its final, post-

accident position and condition. If improper assembly is suspected,
investigators ensure the part or equipment is photographed and
documented as each subassembly is removed.

(2) Items suspected of failure or malfunction are wrapped or boxed to

prevent loss or further damage. Suspected metal failure surfaces should
be washed with 90 percent isopropyl (rubbing) alcohol, which can be
purchased at any drug store. Pour the rubbing alcohol over the fracture

4-5
 surface to remove any dirt or mineral salts, do not rub the surface, and
then blow dry. After washing, apply water resistant uncontaminated
grease to the surface. If there is any question about the grease, use
Vaseline. Carefully tag and mark (place, date, and serial number of the
equipment) all parts so they are easily identified with the accident and
their location at the accident scene. Ensure the tag contains a brief
statement regarding the suspected relationship of the parts to the
cause of the accident. Both the part and the outside of the package are
labeled. Examples of parts that may be preserved for a more detailed
examination are—
(a) Parts suspected of failure.
(b) Parts that appear to be improperly designed or contain faulty
workmanship.
(c) Lines, fittings, wiring, or controls not properly supported and
subjected to excessive strain or vibration.
(d) Ruptured plumbing or fittings.
CH 1 CH 3 CH 4

(e) Faulty wiring, electrical or radio equipment.

(f) Defective engines, drive shafts, transmission and accessories,
such as carburetors, fuel controls, governors and generators.
(g) Defective hydraulic system components.

NOTE: Do not attempt to mate separated items. This will destroy

evidence.

(3) Extreme discretion is used in disassembling parts or components

in the field. If it is known that parts and components will be submitted
for teardown and analysis, disassembly should be avoided, as it tends
to compromise the analysis by destroying or obliterating bits and
shreds of evidence, the value of which may be known only to the
analyst. However, when detailed disassembles are made, all parts
are tagged with complete information to include nomenclature, part
number, locations, and any other significant information. Document all
disassembly with photographs. Assistance in disassembly and inspection
of components, parts, fuel and oil may be obtained from the next higher
echelon of maintenance, U.S. Army depots or other experts identified by
the safety investigation board.

g. A product quality deficiency report (PQDR) is completed for items

suspected of causing or contributing to the accident and submitted to
the proponent agency.

4-6
 h. Check with the on-site safety representative for a copy of the police
report, if applicable.

i. Reassembly of wreckage. It may be necessary to reassemble

wreckage to determine the accident causes or to support a theory in

CH 1 CH 2
an accident that is difficult to evaluate. When the entire system has
been reconstructed, it may afford positive proof of the accident causes.
Wreckage layout should resemble the original equipment as closely as
possible. This gives the investigator a better overview of separations,
fire damage and control system. A detailed and documented inspection
of the wreckage layout will often lead the investigator to the areas or
system that played a role in the accident. The layout also assists the
investigator in developing the sequence of events that occurred in the

CH 3 CH 4
accident.

4-4. VERBAL EVIDENCE/WITNESS INTERVIEWS. (See DA PAM 385-40,

Paragraph 2-3)
a. One of the greatest tools the investigator has in determining
the sequence of events and accident causal factors is interviewing
witnesses. There are three categories of witnesses—

(1) Participants - Individual(s) personally involved in the accident.

CH 5 CH 6
(2) Background witnesses – personnel whose information can aid
the investigation. They include manufacturers, air traffic control (ATC)
personnel, crash rescue personnel, friends and peers, supervisors,
weather briefers, mechanics, etc.

(3) Eyewitnesses - persons who directly observed the accident or

conditions preceding or following the accident as well as persons
CH 7

who heard or saw anything relevant to the subject matter of the

investigation.

b. Locating witnesses. Although witness interviews provide insightful

information, witness recollection rapidly deteriorates and can be
CH 8 CH 9 CH 10

inadvertently tainted through media exposure and from comparing

stories with other witnesses. Statements taken from witnesses located
immediately after the accident are more reliable. To ensure witness
statements are accurate, detailed and as authentic as possible, witness
interviews should be given a high priority.

(1) On-site designated representative and emergency response

personnel (to include MP/CID, local and state police, firefighters,
and paramedics, if applicable) can name the person who provided

4-7
 notification of the incident and those present on their arrival, as well as
provide the most complete list available of witnesses and all involved
parties. Witness statements from police should be obtained for review.

(2) Individuals involved in the accident and eyewitnesses may be able

to help develop a list of others directly or indirectly involved in the
accident.

(3) First-line supervisors can provide information about individuals

involved and provide insight into the planning and preparation phases of
the mission prior to the accident.

(4) Staff in nearby facilities may have assisted or responded to the

accident scene.

(5) News media may have access to witness information and

photographs or videos of the post-accident scene. Obtain copies of local
newspapers, especially if the team gets there a day after. Local media
CH 1 CH 3 CH 4

may have already interviewed eyewitnesses and this gives the board
an initial list of witnesses and a summary of what they saw. Also, check
with the media for video coverage of the wreckage or accident scene.
Most media sources will provide a copy of the video coverage if they
know it will help the investigation. Use caution when using cell phones
around the media. Many of them have scanners that can pick up cell
phone conversations and intentions of the board can be compromised.

c. Interview preparation. Much of the investigation’s fact-finding

occurs in interviews. Therefore, to elicit the most useful information
possible from witnesses, interviewers must be well prepared and have
clear objectives for each interview. Interviews are conducted after the
board has established the areas to be covered and after the board
president has reviewed with the board the objectives of the interviews,
and strategies for obtaining useful information.

(1) Identify all witnesses. Initial contact information should

be provided to the board president from the on-site designated
representatives. The board recorder completes the “Summary of
Witness Interview” form (DA FORM 285-W, for Ground and DA Form
2397-4, for Aviation).

(2) Select a location. The location should present a comfortable

atmosphere, free of distraction and environmental noise when possible.

(3) Schedule an interview with each witness.

4-8
 (4) Select and prepare the interviewer. The number of board
members present during the interview is at the discretion of the
board president. However, more than two or three investigators could
intimidate some witnesses. One investigator should conduct the
interview and maintain eye contact with the witness while another

CH 1 CH 2
monitors and records the interview, and takes notes.

(5) Determine if the Witness is authorized to be offered a ‘promise

of confidentiality.’ (See AR 385-10, Chap 3-10 for clarification and
scope thereof.) The board first determines if the safety investigation
and final report are deemed LIMITED USE or GENERAL USE, depending
on the nature of the accident or the type of equipment or training
involved. AR-385-10 defines both of these categories in Chap 3-10 a

CH 3 CH 4
and b, respectively. Paragraph a identifies LIMITED USE as applicable
to all aviation (flight, aircraft-ground, and flight-related) and friendly-
fire accidents and goes on to stipulate ‘complex systems, operations,
exercises and military-unique items.’ (See AR 385-10, Chap 16-3
for further clarification of the latter.) If the board experiences any
ambiguity with applicability to their accident, verify with the USACRC as
to which category the safety investigation falls because ‘confidentiality’
is restricted to LIMITED USE only.

CH 5 CH 6
(a) If deemed a LIMITED USE safety investigation/report, the
board is encouraged to offer confidentiality to all witnesses associated
with the accident in the interview process. The promise is read to the
witness verbatim, as prescribed in DA Form 2397-4, Block 14, Section
a, for aviation, and DA Form 285-W, Block 14, section for ground
accidents. Note that each of these forms features express verbiage
to delineate the scope of that promise. This is to ensure the witness
understands that, if he/she prefers ‘confidentiality,’ that person can
CH 7

expect the statement to be protected from release outside the DoD,

either to members of the public or the press under the Freedom
of Information Act (FOIA), or state or local governments or federal
agencies. In addition, the person can expect the U.S. Army to oppose
CH 8 CH 9 CH 10

in court, to the fullest extent, any legal order or court order for release
of any witness account/summarization made under the promise of
confidentiality.

(b) If the scope of the investigation does not fall under the caveats
of the LIMITED USE category, then the associated safety report defaults
to the GENERAL USE category. If this is the case, the ‘promise of
confidentiality’ does NOT apply to witnesses. The board does, however,
read to the witness, verbatim, the verbiage in DA 2397-4, Block 14,

4-9
 Section b, for an aviation accident investigation, and DA Form 285-W,
Block 14, Section b, for a ground accident investigation. This is to relay
to the witness that his/her statement will be summarized for accident-
prevention purposes only, within the scope of the safety investigation,
but that the summary may be released to the public pursuant to a
Freedom of Information Act request, with the exception of personally
identifiable information (PII).

(c) If a witness declines confidentiality pursuant to a LIMITED

USE investigation/report, the board communicates to the witness that
the statement/summary, while NOT to be used for administrative or
disciplinary actions within the DOD, may subsequently be released to
the public pursuant to a Freedom of Information Act request, with the
exception of personally identifiable information (PII).

(6) Develop a standardized list of points or objectives to be addressed

in the interview. Ensure all board members understand the objectives
CH 1 CH 3 CH 4

and strategies and use consistent interviewing methods. Read written

witness statements taken by police, CID, or the unit safety officer
prior to the interview. Use the statements to formulate questions to
clarify points or verify witness credibility. Do not limit the focus of the
interview to the accident itself. Use interviews to capture information
pertaining to unit and personnel practices, planning, training, etc. Ask
several witnesses the same questions to corroborate facts.

(7) Develop sketches and diagrams for use during the interview to
pinpoint locations of witnesses, equipment, etc.

(8) Test audio equipment before the interview. Use of an audio

recorder (digital or tape) is the preferred method of recording witness
interviews and should be used unless the interviewee objects. Using
this device allows the interviewer and interviewee to focus on the
content of the interview. Ensure the individual conducting the
interview is familiar with the operation of the recorder.

d. Conducting the interview. It is important to create a comfortable

atmosphere in which witnesses are not rushed to recall their
observations. Witnesses are informed that they are a part of the
investigation effort and that their input is used to prevent future
accidents and not to assign blame. Before and after questioning,
witnesses are notified that follow-up interviews are a normal part of
the investigation process and that further interviews do not mean
that their initial statements are suspect. They are also encouraged to

4-10
contact the board whenever they can provide additional information or
have any concerns. (See Appendix D, Pre-interview Checklist)

4-5. COMMAND DATA.

Determine what decisions were made which may have “set up” the

CH 1 CH 2
accident and the authority level of the person making that decision,
starting from the accident itself back (to include DA level decisions if
appropriate). Collection sources include, but are not limited to:

a. Command Climate Assessments

b. Interviews and observations

c. Records of past unit assessments and inspections

CH 3 CH 4
d. Defense Readiness Reporting System – Army (DRRS-A)/Unit Status
Reports

e. Quarterly training briefs (QTB)

f. ARAP Data

g. Unit policies and procedures for

CH 5 CH 6
(1) Risk Management (risk approval levels)

(2) Pre-mission planning and briefings

(3) Training

(4) Utilization of personnel including rest/sleep plan and operator/crew

selection and training
CH 7

(5) Equipment/vehicle/aircraft suitability and utilization

(6) Pre-deployment or RIP/TOA training documentation

CH 8 CH 9 CH 10

(7) Mobilization/de-mobilization training

(8) Suitability and availability of life support equipment (LSE) and

protective equipment

(9) Maintenance and dispatch procedures

(10) Information flow

4-11
 (11) Pre-accident plan/emergency action plan

(12) Copies of the actual mission briefing and risk assessment

worksheets

h. Collecting both documentary and verbal evidence helps investigators

determine whether personnel in the organization had knowledge of the
policies and procedures as well as the organization’s enforcement of
policies and procedures.

4-6. ENVIRONMENTAL DATA. (See DA PAM 385-40, Paragraph 2-6)

Data pertaining to environmental conditions (at the time of the
accident) is collected for evaluation of its impact or influence on
the performance of the individuals and/or equipment involved.
Environmental conditions include terrain, noise, electromagnetic effects
(E3), lighting, glare, space, quality of air, lunar illumination (moonrise/
moonset) for night or NVC missions, AT for FLIR aircraft and weather/
meteorological (humidity, pressure, temperature, wind and illumination)
CH 1 CH 3 CH 4

conditions. Sources include:

a. Observations from personnel in the vicinity.

b. Weather/meteorological and moon illumination reports from local

forecasters.

c. Radar plot location and altitude data from air traffic control (ATC)
facilities.

d. Maps (topographical and other). Photographs – if needed, satellite

and aerial photos are often available from the installation in both digital
and paper forms.

e. FMs, TMs, and unit policies and procedures.

f. Subject matter experts (SMEs) for evaluation of specific

environmental concerns (occupational health/industrial hygiene
specialist for analysis of workspace and quality of air).

4-7. DATA ANALYSIS. (See DA PAM 385-40, Paragraph 2-8)

The board president and recorder are the key personnel to facilitate
analysis. It is important that all board members review witness
statements, unit and Army-level documents pertinent to the operation,
as well as equipment, training and medical records and note any
anomalies. Ensure board members review their notes as well as

4-12
paragraph 2-8 of DA Pam 385-40 prior to conducting analysis. The
responsibilities and duties of the recorder are as follows:

(1) Post anomalies for review.

CH 1 CH 2
(2) Ensure the macro and micro timelines are posted.

(3) Ensure all documents are organized and available for discussion.

(4) Ensure witness interviews are available to reference.

4-13
 CHAPTER 5
Human Factors Team
5-1 GENERAL.
a. The Human Factors Team usually consists of the medical officer and
other subject matter experts (SMEs) in the mission or training being
conducted when the accident occurred.

b. Medical Officer. The medical officer’s duties and responsibilities are

as follows:

(1) Lead the medical, physiological, and psychological analysis of the

human factors investigation. AR 40-21 (Medical Aspects of Army Aircraft
Accident Investigation), AR 40-2, (Army Medical Treatment Facilities
General Administration) and appropriate chapters of this handbook
govern the investigation and reporting of these factors.

(2) Evaluate accident survival, emergency egress and rescue portions

of the human factors investigations.

(3) Ensure the board is advised of medical/human factors

related to the cause(s) of the accident, the reason therefore, and
CH 5

recommendations for corrective action.

(4) In case of off post accidents or where local coroners/medical

examiners are involved, promptly recover the remains for autopsy
(if applicable), specimen collection, records, etc.. For assistance
coordinating with local coroners/medical examiners contact the Armed
Forces Medical Examiner’s office at 302-346-8648 (DSN: 366).

(5) Investigate and report data concerning personnel injuries this

includes collecting all medical and treatment records and procedure
reports.

(6) Collect and evaluate life support equipment (LSE), and personal
protective clothing and equipment (PCE).

(7) Ensure the human factors narrative for the technical report is
complete.

(8) Determine the medical qualification/status of the personnel

involved and rescue personnel.

(9) Perform other duties as assigned by the board president.

5-1
 c. Subject Matter Experts. Individuals who have considerable
knowledge and expertise in the required fields (instructor pilot, master/
senior/equipment operator, etc.) The duties of other board members
are as assigned by the board president. Other duties include, but are not
limited to the following:

CH 1 CH 2
(1) Examine and record all factors involving operations of the
equipment, to include assignment of personnel, mission planning and
the history of events from mission assignment to the time the accident
occurred.

(2) Investigate and record the status of personnel/individual training,

experience, operating regulation, instructions and unit directives.

CH 3 CH 4
Recommend and prepare changes to ARs and TMs, if required.

(3) Investigate the activities of all personnel involved in the accident,

determine if it had an influence on the mission, or played a role in the
accident.

(4) Assist the board recorder in preparing a sketch of the accident site.

(5) Conduct and summarize witness interviews as necessary for

CH 5 CH 6
inclusion in the technical accident report.

(6) Assist with the writing of the technical report as required.

5-2. MEDICAL & PERSONNEL DATA.

Gather data that provides insight into the performance, health,
qualification and training of the individuals involved in the accident.
Individuals involved include those directly involved, those who
CH 7

influenced the operation, and those suspected to have a role in the

accident. Sources of information include, but are not limited to:

a. Verbal evidence from supervisors, peers, and operations, training

CH 8 CH 9 CH 10

and maintenance personnel.

b. Individual records.

(1) Training and qualification records. National guard and reserve

soldiers’ records are often not brought to theater and must be
requested early in the investigation to allow for transmittal time.
Records include ORB and all NG records maintained by hand at home
station.

5-2
 (2) Equipment/vehicle operator training record

(3) Performance counseling.

(4) Personnel (ORB/ERB) records.

(5) Medical records (include any hospital reports related to the

injuries)

(6) Blood and urine results (as required).

(7) Previous accident history.

c. Evaluating injuries is part of the investigation and therefore autopsy

information is very important.

5-3. HUMAN FACTORS INVESTIGATION.

a. Support. Examine all areas of resource management in order
to determine if adequate support was available to accomplish the
mission or task to standard. The higher headquarters provides the
support; resource management (personnel, money, and equipment/
facilities), organizational climate (structure, policies, and culture), and
CH 5

the operational process (operations, procedures, and oversight) that

ultimately set subordinate commands (and their soldiers) up for success
or failure. Areas to examine include:

(1) Personnel

(2) Equipment

(3) Money

(4) Services

(5) Supplies

(6) Facilities

NOTE: Support includes manufacturing, quality control and design.

Materiel failures are deficiencies created when the materiel is
manufactured. (See DA PAM 385-40, Table B-5 for definitions of support
failures)

b. Standards. Determine if adequate written procedures or guidance

exist to support the mission or task. While the analysis usually focus
5-3
at the immediate task-condition-standard level, the board conducts a
review of all applicable publications-

(1) Field manuals

CH 1 CH 2
(2) Army regulations / Unit policy letters

(3) ACOM and installation regulations

(4) Technical manuals

(5) Training circulars

(6) Graphic training aids

CH 3 CH 4
(7) Division/brigade/battalion/company standing operating procedures
(SOPs)

NOTE: A failure to follow a written procedure is not a standards failure.

A standards failure is the absence of written guidance, errors in the
guidance, or unclear written guidance.

c. Training. Determine if the training was correct, complete, and

CH 5 CH 6
sufficient to enable the individual to perform to established standards.
All applicable individual and collective training should be examined to
ensure appropriate documentation in the individual training folder and
appropriate visibility and tracking at the unit level. This may include
analysis of training received in basic training, military occupational
specialty (MOS)-producing schools, officer basic courses, flight school,
etc. Areas to examine include:
CH 7

(1) Individual training

(2) Crew training

(3) Crew coordination training

CH 8 CH 9 CH 10

(4) Residual training (negative habit transfer)

(5) Weapons training (individual, crew, collective)

(6) Drivers training

(7) Readiness level progression

(8) Pilot-in-command selection and training

5-4
 (9) Unit collective training

(10) TRADOC (schoolhouse) training

(11) Risk management training

(12) Maintenance training

(13) Planning for training

(14) Resourcing training

(15) Unit specific required training (mobilization/demobilization)

c. Leader/Command

(1) Examine the leadership’s role in the accident to determine if

the accident causing mistake can be attributed to a leader’s failure
to enforce standards. Determine if risk management was conducted
properly. Areas to address include:

(a) Unrecognized hazards or hazardous operation

CH 5

(b) Inadequate documentation/procedures

(c) Inadequate supervision

(d) Crew endurance policy

(e) Personnel utilization

(f) Planned inappropriate operation

(g) Failure to correct known problem

(h) Supervisory violations

NOTE: A leader failure can be found when the plan is inadequate.

(2) Assess the influence of command activity, or lack thereof, in

relation to the accident. Apply the risk management 5-step process.
Look at each decision point in the accident sequence of events (from
pre-mission planning to the actions immediately following the accident)
and the authority level of the person making that decision. What
decisions were made along the way that set up the accident? You will
not always be able to determine the cause of an accident, but you can

5-5
determine what allowed it to happen. This provides the unit’s command
solid information, which can be used to implement corrective action
and prevent future accidents. This may also help to identify DA-level
decisions (OPTEMPO, PERSTEMPO, etc.) that set that unit up for failure.
The ultimate goal is to determine if informed decisions were made at

CH 1 CH 2
the appropriate level of authority. As a minimum, investigators analyze
the following:

(a) Overall organizational climate (positive, negative, or indifferent)

(b) Command priorities (training, maintenance, other)
(c) Outside influences on the organization
(d) Application of risk management procedures

CH 3 CH 4
(e) Organizational process (policies, procedures, controls)
(f) Communications (one-way only, open, etc.)
(g) Character of the organization (professional, excessive
centralized control, excessive decentralized control, etc.)
(h) Formal versus informal leadership
(i) Appropriate authority delegated with assigned responsibility
(j) Adherence to established policies

CH 5 CH 6
(k) Mentoring/counseling programs
(l) Command inspection programs

e. Individual. If it is determined that adequate standards existed

and were known to the individual, that the individual was trained to
standard (i.e., training was adequate), and that support was adequate
to perform the task to standard, and the unit’s leadership was adequate
CH 7

the source of the error is probably the individual. Individuals fail to

follow standards for a variety of reasons (lack of professional/self-
discipline, complacency, haste, loss of composure, fatigue, etc.).

NOTE: Reference DA PAM 385-40, Chapter 2, Figure 2-1 to determine

CH 8 CH 9 CH 10

the root causes/system inadequacies of human failure.

5-6
 CHAPTER 6
Materiel Factors Team
6-1 GENERAL.
a. The Materiel Factors Team usually consists of the maintenance
officer and other subject matter experts (SMEs) in materiel accident
investigation and/or other technical advisors for the equipment being
used when the accident occurred.

b. Maintenance Personnel. When possible, maintenance specialists

are assigned to the board. The responsibilities and duties of the
maintenance member(s) are as follows:

(1) Evaluate maintenance forms/records to determine the pre-accident

status of the equipment.

(2) Determine if equipment failed and could have contributed to or

caused the accident.

(3) Research equipment records for adequacy of inspections and

correction of discrepancies. Determine if discrepancies existed that may
have caused or contributed to the accident.

(4) Supervise preparation and shipment of items selected for

teardown/analysis.
CH 6

(5) Monitor equipment recovery if accomplished before completion of

the investigation.

(6) Review unit’s maintenance procedures and record discrepancies.

(7) Ensure all maintenance/materiel factor requirements for the

technical report are complete.

(8) Assist with the preparation of accident scene diagram(s).

(9) Write the materiel factors narrative for the technical report.

(10) Perform other duties as assigned by the board president.

6-2. MATERIEL DATA.

NOTE: for the purpose of accident classification any component
failure resulting from maintenance procedures performed prior to the
Army taking possession of the aircraft is considered a material failure
accident. Any component failure resulting from maintenance procedures
6-1
performed after the Army takes possession of the aircraft is considered a
human error accident.

a. Collect data necessary to evaluate the performance and survivability

of the vehicle, aircraft, equipment (including Life Support and protective

CH 1 CH 2
equipment), buildings, and or other support material. If materiel
evaluation exceeds local capabilities contact USACRC Operations for
assistance at 334-255-2660/3410 (DSN: 558).

b. Equipment records.

(1) As a minimum, collect data from the historical records for the past
six-months such as work orders, modification work orders, services and

CH 3 CH 4
periodic inspection records, as well as other relevant records. Include
information pertaining to—

(a) Component times, replacement schedules and compliance with

modification work order(s) (MWO).
(b) Safety-of-use messages, safety advisory messages, safety-of-
flight messages, ground precautionary messages, maintenance advisory
messages and technical bulletins.

CH 5 CH 6
(c) Current and delayed discrepancies records. Gather all
deficiencies and discrepancies noted for correlation against other
materiel/maintenance factors uncovered during the investigation.
(2) Dispatch/logbook records and the daily inspection

b. Technical reports relevant to the equipment.

CH 7

c. ECODs

d. Lab analysis reports from equipment/component teardown,

fluids, digital source collectors or other like equipment.
CH 8 CH 9 CH 10

e. Technical manuals and technical bulletins related to operation

and maintenance of the equipment involved.

f. Commercial service bulletins, equipment manufacturers,

contractors and other DoD service components with like equipment.

6-3. MATERIEL FACTORS INVESTIGATION.

a. Performance. Determine if the equipment functioned as designed,
and if the design was adequate/appropriate for use. Materiel factors

6-2
 analysis is primarily concerned with evaluating the performance of
the aircraft, vehicle, facility, ground support equipment, land/or other
support material. Data concerning how operational conditions affected
vehicle/ system/equipment performance is also collected. In accordance
with AR 385-10, a Priority Quality Deficiency Report (PQDR) must be
submitted to address materiel failures found during the investigation,
even if it is suspected. The owning unit is responsible for completing the
PQDR and a copy is submitted with the accident investigation report.

b. Appropriate use of equipment. Analysis of materiel factors also

leads investigators to examine if the required equipment was available,
if it was used, and if it was used correctly. If the equipment was not used
appropriately it is not a materiel failure and is assessed as human error.

c. Adequacy of Life Support Equipment (LSE) and Protective Clothing

and Equipment (PCE). Examine the applicable LSE/PCE to determine
if the equipment performed in the manner that was expected or if it
contributed or caused injury. Identify shortfalls in LSE/PCE that should
be addressed.
CH 6

6-3
CHAPTER 7
Advisors
7-1 GENERAL.
a. Advisors can be a general subject matter expert or a technical

CH 1 CH 2
advisor for the equipment used during the accident. Additionally, they
can be part of human factors, materiel factors, or a separate part of the
investigation depending on their expertise.

b. Advisors are not voting members of the board. The board president
has to exercise discretion with reference to the type of information
shared with advisors. As a general rule, advisors are not allowed to
participate in witness interviews. A manufacturer’s representative is not

CH 3 CH 4
bound by Army regulations. Therefore, manufacturer’s representatives,
and anyone else not bound by Army regulations regarding promises
of confidentiality, are not permitted in interviews where promises of
confidentiality are granted. If the advisor has specific questions for the
crew or operator that is deemed necessary to determine equipment
functionality, then a board member may ask that question for him
during the interview.

c. Any outside technical assistance requests or requests to attend a CAI

CH 5 CH 6
in an observer status for the purpose of initial or continuation training is
routed through USACRC operations at 334-255-2660/3410 (DSN: 558).

7-2 TECHNICAL ADVISORS.

a. Technical advisors are usually part of the materiel factors portion
of the investigation and can be Department of Defense personnel or
industry subject matter experts.
CH 7

b. Duties of technical advisors include, but are not limited to:

(1) Provide technical expertise to evaluate equipment.

(2) Assist in detailed teardown analysis.

CH 8 CH 9 CH 10

(3) Coordinate assistance from manufacturer’s facilities.

(4) Complete a technical field report for inclusion in the final report.

7-3 GENERAL ADVISORS.

a. General advisors are usually part of the human factors portion of the
investigation and can be Department of Defense personnel or industry
subject matter experts.

7-1
 b. Duties of general advisors include, but are not limited to:

(1) Provide subject matter expertise to assist in the evaluation of data.

(2) Educate board members on their subject matter expertise.

(3) Provide data for use in the final report.

(4) Advise board members on information needed for the final report.

NOTE: During investigations that involve sensitive and classified

information, add an advisor to the board familiar with what is
authorized or not authorized for disclosure in an unclassified medium.
Information that is not classified can be combined with other
unclassified data to make it classified. For this reason, use caution in a
deployed environment.
CH 7

7-2
CHAPTER 8
Deliberations
8-1. GENERAL.
a. Deliberations are the final stage of analysis and result in the

CH 1 CH 2
development of findings and recommendations. Deliberations are
conducted to:

(1) Identify mistakes/errors, materiel failures, environmental factors

(What happened).

(2) Identify root causes (why it happened).

CH 3 CH 4
(3) Develop recommendations (what to do about it).

b. Every investigation thoroughly examines environmental factors and

materiel performance as potential causes of the accident. However,
the focus of this chapter is on determining human error, both at the
command and individual levels. There are several reasons for this focus.
First, records show human error causes approximately 85 percent of
all accidents. Second, identifying human error is the least objective of
all the causal factors. Third, human error is often present in accidents

CH 5 CH 6
caused by environmental factors and materiel failures. Finally, the
complex nature of human behavior and organizational culture mandates
a systematic approach to investigations to ensure that all areas are
thoroughly addressed.

8-2. PROCEDURES.
The board president chairs the meetings and guides the proceedings.
The recorder ensures products (timelines, anomalies) are posted in such
CH 7

a manner that all board members can see them. All relevant information
remains readily accessible. (See Appendix H)

8-3. PREPERATION.
The recorder prepares butcher charts or dry erase boards prior to
CH 8 CH 9 CH 10

beginning deliberations to capture the findings and recommendations as

the board reaches their conclusions. Prior to deliberations, the recorder
and president brief the board on the use of the charts/tables in DA PAM
385-40 to reach a consensus on the findings (See Appendix H). After the
brief, each board member reviews and has on hand a copy of the task
error and system inadequacy codes from Appendix B of DA PAM 385-40,
prior to conducting deliberations.

8-1
 NOTE: Prior to conducting deliberations, the Board completes their
analysis, agrees on the timeline, remaining anomalies, and the accident
sequence.

8-4. CONDUCT OF DELIBERATIONS.

Deliberations are a formalized process by which members of the board
agree upon the resulting findings and recommendations of an accident.
The findings and recommendations are the enduring foundation
of the investigation and are the mitigating tools to prevent future
accidents. Each member provides input to each finding and assists in
the development of recommendations. The board president may opt to
conduct a vote to ensure that a majority of the board members agree
on a finding and that the task error and system inadequacies correctly
describe the circumstances of the accident. It is important that each
board member participate to the fullest extent possible and arrives to
the deliberation with a full understanding of the facts associated with
the accident.

a. Review anomalies to determine if they were present in the accident

sequence. Active failures are readily apparent, but latent failures require
more analysis. As the factors that were present in the accident sequence
are isolated, place them into the written timeline to develop an event
chart. Then analyze them to determine if they-

(1) Contributed to the accident (present and contributing).

(2) Suspected to have contributed to the accident (suspected present

and contributing).

(3) Did not contribute to the accident, but contributed to the severity
of injuries or extent of property damage (present and contributing to
the severity of the injuries/extent of property damage).

(4) Did not contribute to the accident, but could adversely affect the
safety of future operations (present but not contributing).
CH 8

(5) In no way contributed to the accident, but identify local conditions

or practices that should be corrected or is noteworthy of praise (special
observation).

NOTE: If a potential safety issue has Armywide implications, making the

finding a PBNC rather than a special observation will ensure the problem
has visibility above the accident unit level.

8-2
 b. Task Error identification. Select the most descriptive mistake/error
that caused or contributed to the accident from the list in DA PAM
385-40 Appendix B (Table B-1 for aviation human error or Table B-2 for
ground human error). The more specific the error, the easier it is to
determine the system inadequacies or root causes of that error and the

CH 1 CH 2
corrective actions required. Also, specific mistakes/errors help USACRC
accurately identify accident trends. Regardless of the task involved,
the explanation of how it was improperly performed identifies the
directive, standard, and the performance deviated from or not complied
with. The fact that an error occurred in itself has little meaning until its
consequences and relevance to the accident are also explained. This is a
key concept to understand during the actual writing of the findings and
recommendations. Therefore, the defining and explanation process for

CH 3 CH 4
human errors is not complete until:

(1) It is determined when and where the mistake/error occurred.

(2) The equipment and individual (by duty position) involved is

identified.

(3) The mistake(s) is identified in relation to the deviation from a

performance standard and the proper procedure for performing the task

CH 5 CH 6
is identified.

(4) The directive or common practice governing the performance of

the task is identified.

(5) Consequences of the mistake (the effect) are explained.

c. The mistake/error makes up the first part of the finding. There is

only one mistake/error per finding, but there can be multiple system
CH 7

inadequacies setting the stage for that one mistake/error.

NOTE: In the event of a materiel failure, cite the part number. The
standard is the “mil spec” requirements concerning the manufacture and
CH 8 CH 9 CH 10

utilization of the component. Materiel failures often have human system

inadequacies that can result in a human error finding (failures with
respect to improper maintenance, improper installation and improper
utilization).

d. The next step is to determine the root causes or system inadequacies

that set the stage for the mistake/error and place them into the timeline
(Table B-5 DA PAM 385-40). Again these could be latent failures that
occurred hours, days, or months prior to the accident that set the

8-3
 condition for failure. The best way to identify system inadequacies is
to work backwards from a mistake/error by asking why until an “aha”
moment is reached. Remember that the system inadequacy may have
occurred minutes, hours, days, weeks, or even months before the
mistake/error.

(1) The best source of information is the individual who made the
error or the supervisor(s) of the individual. The interview transcripts
may need to be reviewed and the recordings listened to again. These
individuals may need to be re-interviewed for specificity of detail.
Records and orders may need to be re-examined. The human factors
team also has information from other sources. These include individual
records, unit records, and other people who may have knowledge about
the individual or the accident. A post-accident medical examination may
identify physiological factors (acute fatigue, alcohol, carbon monoxide,
drugs, impaired vision, etc.). The analysis should include a review
of the previous command inspections, FORSCOM Aviation Resource
Management Surveys (ARMS), previous accidents, safety council
minutes, Quality Deficiency Reports (QDRs), etc. for any trends of known
deficiencies and the corrective actions taken by the command.

(2) Select the most descriptive system inadequacy code that set the
stage for the mistake/error or materiel failure from the list in DA PAM
385-40, Appendix B (Table B-5).

(3) The explanation of how the system inadequacy caused or

contributed to the mistake/materiel failure becomes part two of the
finding. Ensure this is added to the timeline/event chart.

e. Develop recommendations that can correct the system inadequacies,

not the mistake/errors. These recommendations are developed for
the appropriate level of command to take action to correct identified
hazards.

(1) When the board reaches a consensus on each significant factor

CH 8

involved in the accident, develop corrective actions having the best

potential for remedying each system inadequacy. The goal is to send
accurate information and timely recommendations to the appropriate
command level for an informed decision. When the board reaches
a consensus concerning corrective actions, the command or activity
having proponency for correcting the system inadequacies is identified.
When this is accomplished, corrective actions can then be directed to
the activity and level of command best capable of accomplishing them.
To achieve the goal of accident prevention, recommendations do not
8-4
focus on specific punitive or administrative actions that deal with the
shortcomings of a particular individual in a specific case. Rather, the
recommendations address the issue on a broader level.

(2) Each recommendation identifies the actions to be taken at the

CH 1 CH 2
appropriate level-of-command, such as unit-level actions, higher-level
actions, DA-level action, or the agency/activity most appropriate to fix
the system inadequacies. Recommendations to division and corps level
are often focused on the METL and War Fighting Function (WFF) that
can rapidly respond to a division commander’s immediate corrective
guidance. Army-level recommendations are focused on doctrine,
organizations, training, materiel, leadership & education, personnel, and
facilities (DOTMLPF) at the Army level and often take months or years to

CH 3 CH 4
respond to corrective input.

(3) The recommendations are written in conjunction with the findings

and included in the technical report of the accident. It is important to
provide the local commander with recommendations to address his
local situation, but it is equally important to provide the chief of staff,
Army (CSA) with recommendations to address the Army wide hazards or
systemic deficiencies.

CH 5 CH 6
(4) Recommendations/Remedial Measures/Countermeasures Code
Identification. Select the most descriptive recommendation code from
the list in DA PAM 385-40, Appendix B (Table B-6) that has the best
potential for correcting the system inadequacies.

(5) The board president does not allow unresolved issues to be

debated indefinitely during deliberations. If a board consensus on
an issue cannot be reached within a reasonable amount of time, the
CH 7

board president decides the issue and continues with the proceedings.
Board members that do not agree with the president’s ruling can file
the reasons for their objections using a minority report. Provisions for
submitting a minority report are in Paragraph 2-1h of DA Pam 385-40.
CH 8 CH 9 CH 10

NOTE: This can be a lengthy process. Analysis can take a day in itself, as
can deliberations. While it is important to not become bogged down, the
board president ensures the board does not rush to conclusions or fail to
find significant mistakes/errors and systemic deficiencies.

(6) It may become apparent during the deliberations that evidence is

conflicting. In such cases, the board usually has two choices:

8-5
 (a) They may further question personnel involved or other
witnesses. If this approach is used, it is probably best to come directly to
the point. Inform the personnel being questioned of the conflict and ask
for an explanation.

(b) If the first approach does not resolve the conflict, it may be
possible to rationalize why the conflict exists and then develop an
explanation. In any case, the board is responsible for resolving conflicts
and carefully weighs the evidence and decides what is most credible.

(7) Once all anomalies are reviewed and findings and

recommendations drafted, the board president and recorder, in
consonance with the board members, work to complete the written
history, narrative, analysis, findings and recommendations IAW
Paragraph 1-7 of DA PAM 385-40. The board reviews the completed
work for technical accuracy and consistency. Any discrepancies are
corrected.
CH 8

8-6
CHAPTER 9
Outbrief
9-1. GENERAL.
At the conclusion of the investigation, the board president prepares

CH 1 CH 2
and presents an outbrief to inform the appointing authority of the
board’s findings and recommendations. It may be 60 days or longer
before the final report is submitted for distribution through command
channels. In most cases, the outbrief is an execution document for the
appointing authority to implement corrective actions. Therefore, the
brief is as thorough and clear as possible. Make it clear the outbrief
is a preliminary report based on information currently available to
the board. Based on the circumstances of the accident, ensure that

CH 3 CH 4
the appointing authority understands that the report may change if
new information is made available (e.g., teardown analysis reveals
unsuspected materiel failure). Assure the appointing authority that the
results of additional analysis are reflected in the final report. The final
report is staffed at a later date after the investigation is closed and all
remaining analysis is complete.

9-2. ATTENDANCE.

CH 5 CH 6
The appointing authority is the primary audience of the outbrief. With
the exception of the board, all other attendees are at the direction of
the appointing authority. In many cases, the installation or unit POC
will ask the board president for advice on who else should attend. As
a general rule, the chain of command down to battalion-level should
be present. In aviation accidents, brigade or battalion-level ASOs, SPs
and/or MEs are normally appropriate. In ground accidents, command
sergeants major or other senior NCOs (e.g., master gunner) may be
appropriate. This brief is not for the general public or other personnel
CH 7

not in the chain of command or in the safety business. All information

contained within the outbrief is for official use only and can only be used
in the prevention of future accidents. The information is not intended
for use as a briefing tool for next-of-kin or family members. Surviving
CH 8 CH 9 CH 10

service members from the accident are briefed as part of their unit and
not as an individual.

NOTE: Pre-briefing the chain of command is not a requirement. Based

on the circumstances, the board president decides if it is appropriate
to pre-brief the brigade and battalion commanders. This is done when
specific command-related or controversial findings are to be presented.
A pre-brief is not conducted if the brigade or battalion commanders
are possible witnesses for the collateral board or have interests in
9-1
 the accident other than accident prevention. The board president
does NOT leave a copy of the briefing after the pre-brief. All available
board members attend the outbrief and the board president ensures
they are prepared to field questions in their areas of expertise. Advise
board members that they represent the convening authority, not their
respective units.

9-3. PREPARING THE OUTBRIEF.

The board president should not wait until the end of analysis before
preparing the outbrief. You can begin preparing the briefing early in
the investigation. Many of the slides can be developed before analysis
begins. Examples include the board members, pre and post-accident
timelines, photographic slides and diagrams, drawings or other
pictures that you may expect to use to discuss analysis. The more
completed before deliberations, the more time you have to develop
a polished product. Inquire early in the investigation as to who might
attend the outbrief, where the brief will take place, and what audio
visual equipment is available. Finalize the briefing after the board
deliberations are completed. This avoids making the slides and writing
the script or briefing note cards the night before when you should
be rehearsing the briefing or relaxing. Personally conduct a recon of
the briefing site a few days prior to eliminate as many unknowns as
possible. Normally, the briefing is given to the command group on the
installation. After the board president has prepared and rehearsed
the briefing, he presents it to the board members. This serves two
purposes: first, it serves as a quality review to resolve any problems,
solicit comments for improvement, and ensure all information is
presented accurately; second, it provides the board president an
opportunity to prepare the board members for possible questions
that may arise during the actual briefing. All board members attend to
provide technical support to the board president.

9-4. RECOMMENDED STRUCTURE.

The board president may utilize the following format for the command
out-brief (see Appendix I). Slides are listed in standard order of
presentation:

9-5. PRESENTATION.
CH 9

The board recorder documents the names and duty positions of

personnel briefed at each briefing conducted, as well as any questions
and comments, to include respective board responses. At no time
is a copy of the briefing left with anyone other than the appointing
authority without approval from the USACRC chain of command.

9-2
If the USACRC chain of command approves a request for additional
copies of the briefing, the briefing is labeled “For Accident Prevention
Purposes Only. This briefing is not for distribution.” Additional approval
is required from the USACRC chain of command to leave a digital
copy of the outbrief with the appointing authority. Upon completion

CH 1 CH 2
of the presentation, the recorder and board president document the
outbrief through a written AAR memorandum for record using the issue,
discussion and recommendation format.

9-6. TIPS FOR EFFECTIVE PRESENTATION.

To assist the board president in presenting the most professional
briefing possible, the following recommendations are made:

CH 3 CH 4
• The board president should write a script for the briefing. Using the
notes pages allows the board president to maintain continuity during
the briefing and assists him in finding his place in the event of a question
or untimely interruption. If you decide to brief from note cards, make
sure you know the briefing thoroughly. Briefing using note cards can
lead to presenting unintended remarks. It is possible to say things you
didn’t want to say and dig yourself into a hole that’s hard to get out of.

• When constructing the briefing slides, use text that is large enough

CH 5 CH 6
for the audience to read. Use a dark colored background with light
colored text or a light colored background with dark colored text.
Slides are very difficult to read when using dark colored text on a
dark colored background or using light colored text on a light colored
background. Remember also, if you have to construct a slide that is not
listed in Appendix I, keep it simple. “Busy” slides make it difficult for the
audience to discern the point you are trying to make.
CH 7

• The board president conducts a practice briefing in front of the

board members. This allows the board members to provide input to the
briefing to ensure all possible questions are answered in the briefing.
Additionally, minor errors, such as spelling, incorrect times, or sequence
of events, can be corrected. Remember “practice, practice, practice.”
CH 8 CH 9 CH 10

The following tips are listed to assist the board president in his
presentation:

• Recon the briefing room.

• Know your audience. Remember, they may have just lost a Soldier.

• Rehearse, rehearse and rehearse again.

9-3
 • Be yourself, be natural, be flexible and be mature.

• Listen. If a question or comment is raised, ensure you have addressed

it before you continue your briefing.

• Be professional. No profanity or off color jokes. Use proper grammar,

pronunciation and enunciation.

• Speak loudly, vary the rate of delivery and avoid monotone.

• Do not be condescending or argumentative. Do not come across

as a “know-it-all.” Discussions with personnel that are not the primary
audience are conducted after the briefing.

• Avoid turning your back to the audience and speaking to the screen.

• Maintain eye contact, scan the audience and look at everyone.

• Do not walk or lean in front of overhead projector.

• Do not pace. Stand behind a podium and use an assistant to change

slides.

• Arrive at the briefing site early. Check all audio visual equipment.
Ensure spare bulbs are available and the seating arrangement is
appropriate for the audience.

CHAPTER 10
Red Book Preparation
10-1. NARRATIVE.
a. DA PAM 385-40 requires the investigation board to report, in

CH 1 CH 2
narrative form, the facts, conditions and circumstances, as established
during the investigation. This portion of the report is the “Narrative
of the Investigation” and is completed for all on-duty Class A and B
accident reports. The narrative is prepared on letter size paper for
ground accidents (Paragraph 4-4, DA Pam 385-40) and on a DA Form
2397-3 (Paragraph 3-6, DA Pam 385-40) for aviation accidents.

b. The narrative of the investigation consists of four sections, the

CH 3 CH 4
history of events/flight, human factors, materiel factors and the analysis.
The first three sections of the report contain factual data and if properly
written are releasable in an un-redacted format under the Freedom
of Information Act (FOIA). The analysis, is reserved for the board’s
documentation of its conclusions, suspicions and opinions concerning
the accident cause and effect relationships.

c. Each section has specific considerations for the board. The board
comments on each of these specific areas, regardless whether causal/

CH 5 CH 6
contributory. In the history, human factors and materiel subordinate
paragraphs, the board can be brief and say the “board concluded not a
factor” when appropriate. However, each subordinate paragraph in the
analysis section includes sufficient information to substantiate areas not
identified as causal or contributory.

d. Outlines of aviation and ground accident narratives are presented

below in Figures 10-1 and 10-2 respectively.
CH 7

(1) Paragraph 1 (History of Events/Flight) presents a sequential

snapshot of the activities and events of the mission leading up to
the accident, the accident, and the immediate actions following the
accident. The timeline established during the investigation assists in
CH 8 CH 9 CH 10

writing this paragraph. It includes enough detail to give the reader

an accurate description of events. Detailed instructions for this can
be found in Figure 3-5 of DA PAM 385-40 for aircraft accidents and
Figure 4-2 for ground accidents. Typical errors in this paragraph include
not clearly identifying the units involved, not detailing the planning
in preparation for the mission, including analytical statements and
including findings. Writers of this paragraph, normally the board
president, include only statements of fact.

10-1
 (2) Paragraph 2 (Human Factors Investigation) is described on Figure
3-5 of DA Pam 385-40 for aviation accidents and on Figure 4-2 for
ground accidents. The medical officer and SME, with assistance from the
board recorder, are responsible for writing this paragraph.

(a) The number one error in this paragraph is not including

information for all personnel involved in the accident. A good rule of
thumb, air or ground, is if there is a finding concerning someone or if
they are a crewmember on board an aircraft at the time of the accident,
include them in this paragraph.

(b) The next most prevalent error is not including enough

information on the individuals listed. Go into as much detail as possible
in the paragraph discussing personnel background information and
personnel management. For example, it is not enough to say that “the
Soldier was assigned to the unit on 1 December 2014” and nothing
more.

(c) In each of the remaining paragraphs, list the required

information as listed in DA Pam 385-40.

 (d) The items below are those DA PAM 385-40 paragraph
4-4c(1) and 4-4c(2) require the board to address in the human factors
investigation portion of the narrative on all individuals involved in the
accident:
1. Briefly summarize service background, to include date of

CH 1 CH 2
service entry (or civilian equivalent), training, experience, type of
assignments, and qualifications acquired prior to joining current unit.

2. Report evidence of safety/traffic violations and prior accident

experience on the primary personnel involved. If involved in a prior
accident, explain their role.

3. Describe experience in mission/duty/activity relative to the

CH 3 CH 4
accident mission/duty/activity, also describe whether the individual
received his/her qualifications by on-the-job training (OJT) or attending
a school. Discuss only those pre-service activities/experiences which are
accident related.

4. Review how the unit/organization has managed the individual

involved. Begin with date of assignment to current unit/organization.

CH 5 CH 6
5. Review experience, training and qualifications upon
assignment and report how individual was tasked, trained, and
otherwise managed up to the date of the accident.

6. Describe how the unit/organization prepared the individual

with qualifications and readiness to perform the mission/activity/event.
Indicate whether or not the individual was qualified to perform the
mission/activity/event involved in the accident.
CH 7

7. Explain irregularities in the individual’s training folder.

8. Also discuss whether the individual was medically qualified to

perform the mission/activity/event involved in the accident.
CH 8 CH 9 CH 10

9. Discuss additional duties and the percentage of time given

them versus their primary duty.

10. Report qualifications acquired since assignment to unit such

as OJT and schooling.

11. Review the procedures involved in selecting the personnel

involved for the mission/activity/event.

10-5
 12. Describe timelines of notification, compatibility of
personnel for the mission/activity/event and their relative experience
for the mission/activity/event.

13. Describe involved personnel in terms of their professional

reputations in the unit, opinions of peers, subordinates and others who
have worked with/for them.

14. Describe the individual’s sleep, work, and dietary habits

and use of alcohol and nicotine. Review unit sleep/rest policy. Report
whether or not a sleep/rest policy was in effect, being monitored, and
complied with.

15. Highlight weaknesses in proficiency, if appropriate,

especially the performance of tasks duplicating those involved in the
accident.

16. Discuss if the individual was receiving medication before

the accident. Report type, source, dosage, side effects and possible
effect on performance.

17. Summarize the findings of the post accident medical

examination. If the individual sustained injuries, give a brief description
of the injuries and how they occurred. If the individual sustained fatal
injuries, briefly summarize autopsy report (if available), to include
cause of death.

(3) Paragraph 3 (Materiel Factors Investigation), The maintenance

officer with assistance from the board recorder is responsible for
writing this paragraph. The principal objective of this paragraph is to
establish the equipment’s condition and serviceability prior to the
accident.

(4) Paragraph 4 (Analysis) is normally written by the board president.

Instructions for writing the analysis are located in DA PAM 385-40,
Paragraph 2-8. For more detailed instructions in DA PAM 385-40 refer
to Paragraph 3-25b(1) for an aviation accident and paragraph 4-4e for
a ground accident. The board president may modify the order of the
environmental, materiel, and human factors sections but makes entries
for each.

(a) The analysis paragraph summarizes the narrative and discusses

CH 10

the opinions, suspicions, and conclusions of the board. The analysis is

10-6
the documentation of board deliberations. It clearly shows the cause
and effect relationship of the evidence gathered during the accident
investigation. Not only does the analysis show the clear cause and effect
of accident causes, but also eliminates plausible accident causes the
board determined did not cause or contribute to the accident.

CH 1 CH 2
(b) The following are required paragraphs for the analysis. The
board makes an entry for each. In each paragraph, develop an analytical
statement or statements and then articulate statements of fact that
support the analysis.

(1) Begin the paragraph by specifying the scope and conclusions of

the investigation. In all cases, begin the paragraph by the words: After

CH 3 CH 4
analyzing the human, materiel, and environmental data collected
during the investigation, the board concluded the accident was caused
by ….” Complete the sentence specifying the factors (human, materiel,
environmental) that caused the accident.

(2) Accident sequence. Include a description of the accident that

includes the board’s estimate of how the accident occurred. This
paragraph creates a picture in the reader’s mind of how the aircraft

CH 5 CH 6
crashed or how the vehicle rolled over, etc. It does not repeat the
history, but includes details of the accident dynamics. Include the
board’s analysis of how and why the accident happened.

(3) Environmental Factors. This paragraph includes meteorological and

non-meteorological factors. Use the key words under Table B-4 of DA
PAM 385-40, describing the environmental phenomena present during
the accident when applicable, along with the results. Environmental
factors can be present at the time of the accident but not causal. There
CH 7

is no present and contributing finding against environmental factors if

the board concludes they were not causal.

(4) Materiel Factors. This paragraph includes all materiel factors.

CH 8 CH 9 CH 10

Use the key words under Table B-3, of DA PAM 385-40 to describe
what happened to a particular part, piece of equipment, system, or
component. Refer to reports written by advisors to the board like
manufacturer representatives. Develop a separate paragraph for each
major component or system. Each statement of materiel failure is
followed by the cause of the failure. Also describe the consequences of
the failure. Identify the part number or the NSN of the part that failed.
Explain why the board ruled out a part, system, or component that could
have caused the mishap. Design or maintenance issues that originated

10-7
 or occurred at the manufacturer are considered materiel issues.

(5) Human Factors. This paragraph includes all human factors. Use
the key words in Appendix B of DA PAM 385-40 to describe issues
associated with each of the human factors system inadequacies/root
causes. Develop a separate paragraph for each of the basic root causes/
system inadequacies and discuss the result of the deficiency. In each
case, develop analytical statements and then support with statements of
fact--
1. Support. Describe issues relating to resourcing, facilities,
services, equipment, number of personnel and other support type
factors.
2. Standards. Describe the adequacy of written guidance for
a particular task. All findings refer to a standard of some type. Be sure
to explain any standards shortcomings and the consequences of those
shortcomings. If the board concluded all documents were adequate,
explain it that way.
3. Training. Describe the training an individual may have
received either in an MOS-producing school, unit, or other. A Soldier
without adequate experience or with some sort of negative habit
transfer is considered to have a training deficit.
4. Leader/Command.
• Leader Factors. Describe what an individual did in his or her
capacity as a leader. Table B-5, DA PAM 385-40 discusses leader failure
as a lack of supervision, but also consider it a leader issue when a leader
chose not to enforce a standard, did not make an informed decision, or
was not where he or she should have been.
• Command Factors. This paragraph discusses topics like risk
management, command climate, unit morale, deployment information,
unit training status, OPTEMPO, command priorities, formal versus
informal leadership, general equipment status, communication up and
down the chain of command, and other issues relevant to the accident.

5. Individual. Discuss the board’s conclusions relative to an

individual Soldier in terms of the error or the indiscipline that caused
the accident or permitted the Soldier to make the error, along with the
results of the Soldier’s actions. Include the injuries to the Soldier in the
results portion of the discussion.
CH 10

6. Other. In this paragraph include special observations (i.e.,

10-8
factors that in no way contributed to the accident but identify local
conditions or practices that should be corrected).

NOTE: If a potential safety issue has Armywide implications, make

the finding a PBNC rather than a special observation this ensures the

CH 1 CH 2
problem has visibility above the accident unit level.

10-6. COMMON ERRORS.

a. Improper Marking: The front of the accident report folder was
not marked with the proper identifying information IAW DA Pam 385-40,
paragraph 4-6e.
CH 8 CH 9 CH 10

b. Report incorrectly labeled as a Limited Use report: Normally

flight, flight related, fratricide, or friendly fire accidents are designated
Limited Use IAW AR 385-10, Paragraph 3-10a. Other complex weapon
systems, equipment, and military unique items may be designated
Limited Use at the approval of the commander, USACRC.

c. The Army Headquarters Reviewing Authority: The Army

headquarters commander or their designated representatives
provides written concurrence or non-concurrence for each finding and

10-15
 recommendation made by the accident investigation board IAW AR 385-
10, Paragraph 3-17c. Additionally, a signature block is required in this
block.

d. Missing Forms: IAW DA Pamphlet 385-40 personnel involved,

meaning any person who was injured or who took actions or made
decisions that generated a present and contributing finding to the
accident, require a separate DA Form 285 or 2397-9.

e. Task Errors: When describing mistakes, use mistakes/task errors

listed in Appendix B to identify the specific mistakes made by the
individual and included the results of the mistake.

f. Findings and Recommendations:

(1) All elements of a finding were not present and the task errors and
root causes were not clearly identified in the findings.

(2) Names are not used to identify individuals in the findings.

Individuals are identified by duty position.

(3) DA Level recommendations should have been directed at the

unit, command or activity which was best capable of implementing
the actions contained in the recommendations IAW DA Pam 385-40,
Paragraph 4-3f(4).

(4) A present and contributing finding is not a standards failure if

a clear standard published. Failure to adhere to the standard is an
individual failure, not a standards failure.

g. Narrative of Investigation. The analysis identifies errors that

occurred in the accident sequence and contains an explanation of the
system inadequacies that caused or permitted an error, failure, or injury
to occur.

h. Summary of Witness Interview:

(1) A promise of confidentiality can only be made in a Limited Use
accident investigation and cannot be offered in a general use accident
investigation IAW AR 385-10, Paragraph 3-10 and DA Pam 385-40,
Paragraphs 2-3a(4).

(2) Witness summaries are not a verbatim copy of questions and

answers used in the interview. Questions and answers are summarized

 APPENDIX C
APPENDIX C: Board in-brief
GENERAL. In most cases, this is the first time any of the board
members have performed an accident investigation. It is important
that everyone understand the mission and end result of the accident
investigation. The initial board briefing, conducted by the president,
should include the following:

a. Introductions (office/telephone number).

b. Ensure board is comprised of personnel qualified in the system

under investigation; i.e., technical inspector (TI), maintenance officer,
medical doctor (per DA PAM 385-40).

c. Explain (and ensure understanding) that they are to be dedicated to

the investigation (reschedule calendars for three weeks).

d. Explain investigative mission:

(1) For accident prevention purposes only.

(2) Human/materiel/environmental causes.

(3) Approximate duration of investigation (2-3 weeks).

(4) Recap date/time/summary of accident.

(5) Review DA Pam 385-40 as a guide for completing the forms.

e. Explain investigation:

(1) Data collection phase- Collection of factual information. Stress the

need for organization of data and the use of an investigator’s notebook
to assist in organizing data and providing the complete context in
which it was collected. This will prevent delay during analysis and
deliberations.

(2) Analysis phase- Analysis of the factual information to determine

its relevancy/correlation to the accident. Additional data collection may
ensue pursuant to those issues raised during this phase.

(3) Deliberations phase- The board’s proceedings to collectively

identify the cause of the accident, determine why it occurred, formulate
the findings, and present recommendations to prevent recurrence.
APPENDIX C
f. Assign work groups/leaders:

(1) Human factors (doctor, instructor pilot/training SME)

(2) Materiel factors (test pilot, technical inspector/maintenance

technician)

(3) Environmental factors (as required).

g. Explain report preparation

h. Assign responsibility for report sections:

(1) History of flight/events (president)

(2) Human factors

(3) Materiel factors

(4) Analysis (president)

(5) Findings/recommendations (president)

(6) DA Form 2397/285 series (all groups)

i. Establish a daily meeting time(s) to exchange information

j. Allow work groups organization time

k. Request for support personnel (i.e., CCAD, Natick Lab, AMCOM, etc.)
is coordinated through USACRC operations, DSN 558-2660/3410

president)

m. Discuss work relationships with technical advisors (e.g.,

manufacturers)

n. Discuss work relationship with the collateral investigation board

o. Collection of all notes, materials, etc. at completion

p. Use of cell phones and potential release of information. Type of

information appropriate for cell phone: facts only. Do not discuss
findings, recommendations, analysis, opinions, etc.
 APPENDIX D
APPENDIX D: Pre-interview checklist
GENERAL. It is important to create a comfortable atmosphere in which
witnesses are not rushed to recall their observations. Witnesses are
told that they are a part of the investigation effort and that their input
is used to prevent future accidents and not to assign blame. Before and
after questioning, witnesses are notified that follow-up interviews are
a normal part of the investigation process and that further interviews
do not mean that their initial statements are suspect. Also, encourage
the witness to contact the board whenever they can provide additional
information or have any concerns.

(1) Create a relaxed atmosphere-

(a) Conduct the interview in a neutral location that was not
associated with the accident.
(b) Introduce yourself and shake hands.

(c) Be polite, patient and friendly.

(d) Treat witnesses with respect.

(e) Determine whether the witness has any issues that might
interfere with conducting an effective interview (language, vision,
hearing, seating, need for frequent breaks, etc.).

(2) Prepare the witness (board recorder)-

(a) Describe the investigation’s purpose: to prevent accidents, not
to assign blame, and the promise of confidentiality, if appropriate.

(b) Stress how important the facts given during interviews are to
the investigation.

(c) Explain that witnesses may be interviewed more than once.

(d) Let the witness know the interview session will be recorded
unless they object.

(e) Using the witness interview summary form, complete the

form’s header information and brief the witness using the appropriate
statement from block 15. If offered a promise of confidentiality, have the
witness initial the appropriate statement in Block 16 of the form.

(3) Things to avoid during the interview (review with board)-

(a) DO NOT rush the witness while he/she is describing the
accident or answering questions.
APPENDIX D
(b) DO NOT judge, display anger, refute, threaten, intimidate, or
blame the witness.

(c) DO NOT suggest answers.

(d) DO NOT make promises that cannot be kept (for example,

unrestricted confidentiality).

(e) DO NOT use inflammatory words (violate, kill, lie, stupid, etc.).

(f) DO NOT omit questions because you think you already know the
answer.

(g) DO NOT ask questions that suggest an answer, such as “Was the
odor like rotten eggs?”

(h) DO NOT embarrass a witness by reacting to obvious errors.

(i) DO NOT interrupt the witness.

(4) The interview-

(a) Start the audio digital recorder and begin the interview by
obtaining the “header” information. Ensure the information is stated out
loud (in case more than one interview will be digital recording on the
same tape).

 APPENDIX H
APPENDIX H: Deliberations process
FINDINGS. Determine findings using the following methodology:
1. Group anomalies into three categories:
- Environmental, materiel or human

2. Review anomalies to determine if they were present in the accident.

Then analyze to determine if they were:

- Present & Contributing (PC) - Contributed to the accident.

- Present & Contributing to Severity of the Injury or Damage (PC

S/D) - Did not cause the accident, but contributed to a more severe
injury or greater damage

- Present but not Contributing (PBNC) - Did not contribute, but could
cause an accident in the future

- Suspected PC- Suspected to have contributed to the accident

- Special Observation (SO) - In no way contributed, but the board
determined the chain of command should be informed (positive or
negative)
- Freebie (F) - Minor discrepancies that are brought to the chain of
command, but are not in the final report.
3. Refer to DA PAM 385-40, Appendix B to determine a task error for
the anomaly
(One per finding):
- Table B-1: Aviation Human Task Errors

- Table B-2: Ground Human Task Errors

- Table B-3: Materiel Failures/Malfunctions

- Table B-4: Environmental Conditions

4. For human task errors, refer to DA PAM 385-40, Figure 2-1 in

conjunction with Table B-5 to determine root cause/system inadequacy
(there can be multiple system inadequacies).

5. Record the following information to assist in writing the finding using

Table 3-1 in DA PAM 385-40:

- When and where the mistake/error occurred

APPENDIX H
- Equipment and individual (by duty position) involved

- Identify the mistake/error in relation to a deviation from a standard,

directive, or common practice governing the performance of the task

6. Develop recommendations using DA PAM 385-40, Table B-6

 APPENDIX I
APPENDIX I: Outbrief standards
OUTBRIEF STRUCTURE:
1. Introduction. Start with the appropriate greeting, “Good morning
or good afternoon, sir” and an introduction of yourself. Continue by
stating, “This will be an information briefing on the aircraft or vehicle
accident that took place at (location) on (date).” Continue with your
slides from this point.
This introductory slide includes:

- Aircraft, vehicle, equipment or task involved in the accident

- Classification
- Location
- Date
2. Disclaimer. Inform the audience this is a preliminary briefing
and that there may be minor adjustments to the findings and
recommendations based on additional information that may become
available to the board. This slide also serves as an opportunity to excuse
from the audience any JAG or 15-6 personnel.

3. Board Members. Use this slide to introduce your board members.

4. Background. The appointing authority may be familiar with much

of the information on this slide. He/she knows the unit, equipment,
date and location. Be brief. However, he/she may not know the extent
of injuries and total cost. Summarize the mission or task. Often, this
provides you an opportunity to talk at the macro level as a lead-in to
your next slide.

5. Personnel Involved. Use this slide when the linking of duties and
the associated injuries supports the findings and recommendations.

6. Seating Diagram. Use a diagram of the vehicle/aircraft/formation

to depict individual locations if it helps to present a clear picture of the
conditions just prior to the accident.

7. Pre-accident Timeline. Similar to the written history paragraph, this

slide frames the accident. Include data that is relevant to the accident.
Show when training occurred (or didn’t occur), some important personal
or unit history, etc. Talk through the sequence of events until the
accident occurs, this makes a good transition into the next slide.
APPENDIX I
8. Accident Site Photographs. A series (2-4) of photographs, start with
the big picture and narrow down to a close-up of the accident. Identify
relevant data in a lower block on the photographs. From the macro view
photograph, begin to show more detailed photographs of the accident
site. Use accident site photographs, to include aerial photographs that
allow the audience to get a clear picture of the site. Additionally, the
photographs orient the audience to the direction of travel, impact angle,
and include a compass rose. You may insert other sketches, diagrams
or drawings. Make the determination if they belong here or in the
analysis section. If the photograph shows “what happened” put it here.
Photographs are included to illustrate and support your findings.

9. Post-Accident Timeline. Used to show how the unit or installation

reacted to the accident. Medical response timelines are highlighted.

10. Analysis. Don’t spend an inordinate amount of time on this slide.

Use subsequent findings and recommendations to present your analysis.

11. Summary of Findings. Use this slide to briefly summarize the

findings of the investigation. This allows your audience time to process
key information before reviewing the findings and recommendations
that are written using required terms from DA PAM 385-40.

12. Findings and Recommendations. Allow the appointing authority

time to read the each slide before you talk. After he/she reestablishes
eye contact, summarize what he/she read. Unlike the findings, cover key
points to each recommendation on this slide to ensure the appointing
authority understands the intent of the recommendation.

13. Conclusion. Inform the appointing authority that this concludes

your briefing and ask them if there are any questions or comments. The
recorder takes good notes on the appointing authority’s questions and/
or comments.

APPENDIX K
APPENDIX K: Media guidance
GENERAL. The level of media interest varies depending on the severity
of the accident. It may range from no interest at all to concentrated
national attention. The appropriate course of action is to allow the
installation or the nearest local public affairs officer to address media
requests. If a PAO is not immediately available, the board president
may be required to interface with the press at the accident site. The
following guidelines govern the president’s handling of the media:

a. The board president is the sole interface with the media. Board
members refer requests for information to the board president.

b. Cooperate with the media to the extent possible.

c. Do not speculate as to the cause of the accident. The following

statement is all that should be provided: “An investigation of this
accident is now ongoing; please refer all of your requests for information
to the local installation, U.S. Army Combat Readiness Center, or
Department of the Army Public Affairs Office.”

NOTE: Give the name and contact number of local PAO; if not known,
be courteous and get the name and number for the reporter. This
shows good faith and an attempt to be as helpful as allowed within the
scope of the mission and regulations. If you can’t get access to local
PAO information, give the name and number of the U.S. Army Combat
Readiness Center or Department of the Army Public Affairs Office to the
reporter (U.S. Army Combat Readiness Center: Public Affairs Office, 334-
255-3770; Department of the Army Public Affairs Office: Media Relations
Division, 703-697-7550).

d. In most cases, news reporters understand that it is too early in

the investigation to determine what happened and that you will
not speculate about the cause of the accident. Without giving the
appearance of trying to conceal anything or pass questions off lightly,
the board president should advise reporters that the post or local PAO is
the point of contact for responding to all of their future questions.

e. Accident investigation boards are not authorized to provide periodic

updates in the form of news releases or press conferences to either
media representatives or local PAOs. Board presidents should ask PAOs
to seek information from other sources to use in responding to media
requests for updates. Board presidents guides PAOs in the direction
of the collateral board for obtaining information to be released to
 APPENDIX K
the media. One of the primary intents of a collateral investigation is
to provide a means of answering the public’s concerns regarding the
accident.

f. No attempt is be made to tell reporters what should be written in

their stories or to restrict them from interviewing civilian witnesses.
However, do advise military personnel against making statements,
expressing opinions, or giving out information concerning the accident.

g. In many instances, the news reporters are able to provide a great

deal more information than they receive. Sometimes reporters are
among the first persons to arrive at the accident site, and they may have
talked to several witnesses before the rescue party arrives. This fact may
not be apparent from their conversations, which probably will consist
primarily of questions. Rather than strain relations at an accident scene
by quoting regulations as the reason why you cannot provide reporters
with accident details, attempt to be cordial and helpful, yet firmly refer
reporters to a public affairs officer. Remember you may find it necessary
later to interview the reporter as well.

h. In most cases, the reporters are happy to pass their information

along to the individual in charge of the accident scene and give the
investigation team further assistance as needed if they understand
the value of their efforts to the safety program. If the news agency
is asked to provide photographs or film clips, be advised that a fee is
usually involved, so arrangements for financing are made before making
this kind of request for assistance. The same caution applies to other
nonmilitary agencies (police, fire departments, etc.).

i. When an accident occurs on nonmilitary property, media personnel

should be allowed complete freedom in taking photographs from
outside the secured area. If classified material is involved, the
photographer should be advised of such. If necessary, the photographer
may further be advised that the photographing of classified material
may constitute a violation of Federal law (18 U.S. Code, Section 797).
Any such classified material is either covered or removed before
photographs are taken. Although no restriction is placed on the
photographer, a tactful request usually prevents use of photographs that
would violate propriety. Media personnel should also be advised that
the notification of next-of-kin may not have been accomplished.
