Section A: Explanatory Material

Introduction

0.1. Scope and applicability

CASA is responsible for establishing procedures detailing how applications and approvals
under Part 145 of the Civil Aviation Safety Regulations 1998 (Part 145) are managed.
This CASA Sample Maintenance Organisation Exposition (MOE) Acceptable Means of
Compliance/Guidance Material (AMC/GM) document is applicable to Part145 applicants and
Part-145 Approved Maintenance Organisations (AMO). The provisions of this document are
complementary to the requirements of Part 145 and the Part 145 Manual of Standards made
under the Civil Aviation Safety Regulations 1998 (Manual of Standards) and does not
supersede or replace the associated legislative requirements.

0.2. Purpose
This CASA Sample MOE is designed to be used by:

 maintenance organisations - New applicants to assist them in the production of their

own MOE
 approved maintenance organisations - To assist the AMO with compliance updates etc
and continuous improvement of their own MOE
 CASA - As a comparison document for MOEs submitted for assessment / approval.

0.3. Communication
All documents and correspondences between the maintenance organisation and CASA must
be written in the English language.

General guidance

0.4. Preliminary considerations

The MOE must be developed by each organisation to demonstrate how they comply with:

 Part 145, Manual of Standards and

 Part 42 regulations applicable to maintenance organisations which are not already
referred / mirrored in Part 145.

For each detailed procedure described within the MOE, and to ensure their effectiveness, a
procedure should describe the who, what, when, where, why and how of the task or action to
be carried out. These procedural requirements as applicable can be described as follows:
(a) Who: is responsible; is procedure applicable to (contractor; certifying staff, mechanic etc);
will accomplish the procedure, etc
(b What: is the procedure is about; is to be accomplished; what the person(s) performing the
procedure should do, etc
(c) When: the procedure is to be accomplished (frequency-date / time / hours cycles) etc
(d) Where: the procedure will be carried out (facility type / room / building / location) etc

Part 145 Sample Exposition - 2.0 September 2020

Page 7
(e) Why: the procedure is required to be accomplished (requirements may vary subject to
applicability (who))
(f) How: the procedure will be accomplished according to (AMM, National standards, etc); the
responsible person determines what procedure will be used and if it has been
accomplished.

0.5. Terms in use

For the purpose of this document, the references to the CASA Sample MOE document are
identified by use of following terms:
“MOE Part” is used to identify the main parts of the MOE (e.g. meaning Part 1 Management,
Part 2 Maintenance Procedures, Part L2 Additional Line Maintenance procedures, Part 3
Quality and Safety Management, etc.) as identified in the MOS AMC 145.A.70(a);
“MOE section” is used to identify each section within an MOE Part (e.g. MOE 1.2 Safety and
quality policy, MOE 3.3 Quality audit of aircraft (and / or aeronautical products, etc), as
identified in the MOS AMC 145.A.70(a);
“MOE subsection” is used to identify a subsection within an MOE section (e.g. MOE 1.3.3
"Quality Manager" MOE 3.5.1 “Aircraft certifying staff”, etc.). At the subsection level the
numbering system is not pre-identified in the Part 145 MOS AMC and it is left to the applicability
of the organisation ensuring regulation requirements are addressed. Further division to sub-
subsections may also be used. When an “MOE subsection” is identified in this sample MOE
and is applicable, the same subsections structure is expected to be found in the organisation
MOE.

0.6. CASA sample MOE writing conventions

The document provides for various information, acceptable means of compliance and guidance
material under MOE Parts, sections and subsection headings for an organisations Exposition.
Those Parts and sections relate directly to the Exposition content specified in MOS AMC
145.A.70.
The text provided under each section or subsection of this sample MOE provides suggested
subject headings and / or additional guidance, comments, examples etc for the nature of
contents to be included. No sample Exposition can meet the needs of all types and sizes of
organisation or, indeed, reflect the different organisational structures. The sample MOE
provides recommended / specimen text. It is the responsibility of the maintenance organisation
to identify applicable content for that organisation and the sections and subsections should be
further developed according to the complexity of the organisation, its processes, and
procedures.
To facilitate the reading and understanding for use of this sample MOE, the following writing
conventions apply to each MOE section.
Regulatory references
Reference to the applicable regulatory requirement are identified at MOE sections / subsections
as applicable and should be considered with applicable MOS AMC/GM.
A "compliance matrix" cross-reference table between MOE sections / subsections versus the
regulations / AMC / GM references is provided for further development as applicable to the
organisation, contained at MOE section 6.6.

Part 145 Sample Exposition - 2.0 September 2020

Page 8
CASA recommends the organisation correlates the content of the Exposition with a compliance
matrix/check list to demonstrate to CASA that they have fully addressed all applicable
legislation requirements of CASR Parts 42, 145 and Part 145 MOS. An accurately completed
compliance matrix/checklist will benefit the AMO as a component of their QMS compliance
requirements and aid future MOE changes.
Specimen content
The Normal Font text other than the described "Examples" and "Comments" provides
information to develop suitable content, to utilise for expanding the subject headings, bullet
point text etc and addressing any applicable explanatory comments or guidance. This text
illustrates the nature of the content required. The organisation should carefully consider the
information and content provided for suitability and applicability to the organisation.
Examples:

 when major examples are being made to better visualise the type of MOE content, the
term “Examples” in bold capital letters will proceed the example made
 In case of a minor example within a text, which is done only to clarify the meaning of
the text, the example is contained in brackets and preceded by the abbreviated term
“in example”, such as (e.g. text of the example, etc.).

Comments: Comments and supporting information are inserted in “italics” font. They are not
supposed to be themselves an expected content but only intended to provide additional
clarifications.

0.7. Structure and content of the MOE

The MOE may be produced in the form of a single document format or may consist of several
separate documents.

 Single document: The standard MOE, produced in accordance with MOS AMC
145.A.70 (a), is a unique and complete document. It must contain all the information
required to show compliance with the applicable legislation including detailed
maintenance procedures and detailed quality and safety system procedures.
 Several documents: The MOE must contain at least the information as detailed in MOS
AMC 145.A.70 (a) Part 1 Management - the management sections 1.1 to 1.11 which
reflect applicable requirements of the legislation MOS 145.A.70(a). The additional
material may be published in separate documents which must be referenced from the
MOE. The referenced documents form part of the Exposition and are subject to the
same requirements and controls as the Exposition. In this case:
 The MOE must cross refer to the associated procedures, documents, appendices,
forms and all other lists which are managed separately (e.g. the list of certifying
staff, the capability list, the list of sub-contractors, etc).
 Therefore, the MOE section 1.11 is expected to contain a summary of all
associated documents / procedures / lists etc and their references. (refer to the
MOE section 1.11 for further guidance).
 All associated documents form part of the MOE therefore must be subject to the
same controls, procedures and legislative requirements as described for the MOE.
 All associated document(s), procedure(s) and form(s) etc. must be provided to and
approved by the CASA (as part of the MOE).

For standardisation purposes and to facilitate the production of the MOE by the maintenance

Part 145 Sample Exposition - 2.0 September 2020

Page 9
organisation, CASA recommends adoption of the standardised MOE Table of Contents
provided in this sample MOE document “Table of Contents” (e.g. MOE Part 1 to Part 6)
consistent with the MOS AMC 145.A.70. The maintenance organisation should customise the
document to suit their organisation and may add pages/paragraphs as necessary.
Processes and procedures etc included or referred to must be of adequate depth and include
enough details to demonstrate they establish compliance with the applicable legislation
requirements.
For some organisations certain Parts, section or subsection headings defined within MOS AMC
145.A.70(a) and / or this sample MOE may be ‘not applicable’. In this case they should be
annotated as such within the MOE.
The assigned CASA inspector will refer to this sample MOE and assessment criteria when
reviewing the applicant's submitted MOE. Where the applicant's MOE format differs from this
document sample MOE, this will result in additional workload and time, therefore the
maintenance organisation is strongly recommended to follow the MOE structure described in
MOS AMC 145.A.70(a) and this CASA Sample MOE.
Where the applicants MOE uses a different format, the Exposition should contain a cross
reference annex utilising the list within the MOS AMC 145.A.70(a) or this sample MOE
documents Parts, sections, subsection headings as an index with an explanation as to where in
the applicant's MOE the subject matter can be found.

The MOS AMC 145.A.70(a) 3rd paragraph states: “Where an organisation uses a different
format, for example, to allow the Exposition to serve for more than one approval, …”
To further explain, this MOS AMC must be read in conjunction with the applicable Australian
regulations, therefore limiting the use of the Part 145 MOE for CASA approvals covered by the
legislation. Consequently, the CASA Part 145 MOE, associated procedures and lists must only
make reference and be dedicated to applicable CASR Parts 42, 145 and associated legislation
unless the legislation also permits and specifies National Aviation Authorities (NAA)
arrangements.

0.7.1 Exposition pages - Presentation

Each page of the MOE must be identified (this information may be added in the header or
footer), as applicable depending on how the organisations Exposition implements revision
controls and ensures consistency with MOE section 1.11 procedures for managing the
Exposition. (Refer to the Examples provided at the CASA sample Exposition Section C: MOE
Structure and Content, subsection C2 "LEP" and C3 "Amendment Record" for further
information).

 the name of the organisation (official name as defined on the CASA approval
certificate)
 the Issue number of the MOE
 the Issue date
 the Revision number of the MOE
 the Revision date
 the MOE section (e.g. 1.3)
 the page number
 the name of the document "Maintenance Organisation Exposition”.

Part 145 Sample Exposition - 2.0 September 2020

Page 10
Part 145 Sample Exposition - 2.0 September 2020
Page 11
The cover page of the volume should specify:

 the title “Part 145 Maintenance Organisation Exposition”

 Unique identification number given to the MOE (e.g. AMONAME-CASA-DOC1).

A unique identification number is expected for each document which is part of the CASA
approval. It is particularly helpful when managing approvals of documents.

 The name of the organisation (the official one defined on the CASA approval
certificate)
 The principal address (main location), telephone, fax numbers and the e-mail address
(generic) of the organisation
 (The generic email address prevents additional administrative changes as it remains
independent should respective persons in charge leave the company)
 The copy number from the distribution list
 The approval reference of the Part 145 organisation.

0.8. MOE Initial assessment / approval process

0.8.1. First Submission - Initial “Draft” MOE
Prior to submission of the applicant's draft MOE to CASA for assessment / approval, the
Accountable Manager must sign and date the Corporate Commitment Statement (MOE section
1.1). This confirms that they have read the document and understand their responsibilities
under the approval. Change of the Accountable Manager will require the new incumbent
manager to sign the document and submit a suitable amendment to CASA for approval.
0.8.2. Tracking Changes to the Initial Draft MOE
Following the receipt of the first “draft” MOE, CASA will review and assess the draft and
formulate remarks in writing to the maintenance organisation.
On receipt of such remarks, the maintenance organisation is expected to revise the first “draft”
and produce a second “draft” MOE, where all the remarks have been addressed. In order to
have a clear tracking of the changes and to allow the review of the revised MOE by CASA
following is expected:

 The maintenance organisation replies in writing to each remark explaining how it has
been addressed and in which MOE section/subsection
 The maintenance organisation issues a second “draft” MOE, which clearly identifies
the introduced changes. This can be achieved by:
 Maintaining the MOE “draft” identified as “initial” (i.e Issue 1, Rev. 0), but changing
the date to identify the new draft issued
 Identifying clearly the text modified in each MOE section/subsection (e.g. using
vertical bars, highlighting text with a specific colour, etc.).

This process will continue with the issue of a third, fourth, etc. “draft” MOE as required, until the
Exposition is considered acceptable by CASA in order to proceed further with the technical
investigation process.
Important note: The same principle applies to the successive revisions of an approved MOE
and also to the documents associated to the Exposition such as procedures and lists which are
also subject to approval.

C3. Amendment record

This section should set out the amendment record of the Exposition. The control of
amendments must be consistent with the procedures for managing changes to the Exposition
detailed in MOE section 1.11.
In order to properly monitor the approval, it is essential that the organisation clearly identifies
the initial edition of the Exposition and each subsequent change. Any change to the approved
MOE is identified (depending on the numbering system / convention chosen) such as:

 A new Issue and/or Revision number

 A new Issue and/or Revision date
 Clear identification of the modified text in each MOE Part / section / subsection (e.g.
using vertical change bars, highlighting text with a specific colour, text track changes,
etc.).
Depending on the complexity and need of the organisation, the following two examples provide
possible recommended options:
The chosen option must reflect the procedures detailed in MOE section 1.11.

Example 1
This option is intended to relate to an MOE identified by both an Issue number and a Revision
number, in particular, each time the Issue number is changed, the Revision number will start
again from “0”.
There may be various reasons to choose this option of double identification, for example to
identify significant changes (Major) of the organisation with a change of the issue number and
each change which is not significant (Minor) by changing the Revision number.

Part 145 Sample Exposition - 2.0 September 2020

Page 18
The following table is given as an example:
Issue Issue Revisio Revisio Revisio Reason for change
No Date n No n Date n Type
1 22/11/13 0 22/11/13 INITIAL N/A
1 26/01/14 Minor Update to tooling procedure
2 30/06/19 0 30/06/19 Major Change to A1 scope of approval

Example 2
This option is less flexible than "Example 1", because any change to the MOE will be identified
only by a change in the defined (Revision (or) Issue) number.
The numbering of the (Revision (or) Issue) will start with “0” and increase for each amendment.
The following table is given as an example:
Revisio Revisio Revisio Reason for change
n (or) n (or) n (or)
Issue Issue Issue
No No Date No Type
0 22/11/13 INITIAL N/A
1 26/01/14 Minor Update to tooling procedure
2 30/06/19 Major Change to A1 scope of approval

C4. Distribution list

This section should include a distribution list to ensure proper distribution of the Exposition and
to demonstrate to CASA that all employees involved in maintenance have access to the
relevant information. This does not mean that all employees have to be in receipt of a complete
Exposition but that a reasonable number of copies are distributed within the organisation so
that employees may have quick and easy access to this Exposition.
Alternately, if the manual is available electronically this section should set out how the
electronic version is available throughout the organisation and to individuals outside the
organisation.

(a) and subparagraph 145.A.70 (a) 1 of the Part 145 MOS refers)

The Accountable Manager's Exposition statement should include the intent of the following
paragraphs. The following statement may be used without amendment. Any changes to the
statement should not alter the intent.
I, the Accountable Manager have the corporate authority to ensure that all maintenance
services required by the customer can be financed and provided to the standard required and
that all necessary resources are available to enable compliance with this Exposition.
I will establish and promote policies for safety management and quality systems for this AMO
and its employees in accordance with this Exposition.
This Exposition defines the procedures upon which the CASR Part 145 approval of
[organisation name] as an AMO is based.
The Exposition, along with the procedures contained in it, are approved by CASA and must be
complied with as applicable, in order to ensure that all the activities involving the provision of
maintenance services, including maintenance of aircraft and aeronautical products, are
provided to the standard required under the legislation.
The procedures included or referred to in this Exposition do not override the necessity of
complying with any new or amended regulations published by CASA from time to time where
these new or amended regulations are in conflict with these procedures.
The AMO approval will continue whilst CASA is satisfied that these procedures are being
followed. CASA reserves the right to suspend, vary or cancel the AMO approval of the
organisation, as applicable, if CASA has evidence that the procedures are not being followed
and the standards are not being upheld.

  Type of documents (evidences).

The list(s) may be directly inserted in this section of the MOE or managed as a separate
associated list(s). For example, it is possible to cross-refer from this MOE section 1.5 to
another record (including a computer record) where a list of the authorisation holders are kept.
In this case an explanation of where the list is maintained and how it is updated must be
included in this paragraph thereby meeting the intent of the CASA requirement.
This list(s), whether included to or separately referenced from the MOE, is an integral part of
the approval. This means that it is approved (directly by CASA on initial approval, via approval
of a significant change or by the organisation through a procedure which has been previously
approved by CASA where the change to the list would not constitute a significant change (refer
to Chapter MOE sections 1.9, 1.10, 1.11).

1.5.7 Certifying staff (NAA licence holder other than CASR Part 66)

Part 145 MOS refers)

This section should demonstrate how the organisation ensures the AMO has sufficient
employees to plan, perform, supervise, inspect and certify for maintenance and audit the AMO
for compliance and safety in accordance with the Quality and Safety Management Systems
required by paragraphs 145.A.65 (c) and (d) of the Part 145 MOS for each maintenance
function and location. The AMOs policies relating to the number of employees required under
various types of maintenance and the levels of supervision required between individual
maintainers and Certification Authorisation holders should be shown here consistent with the
Production Planning system.
The organisation must be able to demonstrate that they have adequate manpower resources to
support and justify the entire scope of approval. The details should be sufficient to explain the
support at each facility / location and each function as required by MOS 145.A.30(d).
The organisation should not declare a percentage of staff used but indicate the number of staff
needed to comply with Part 145 requirements so a clear picture is given without the need for
amendment to this section as a result of insignificant routine staff fluctuations. The organisation
must however be able to highlight any significant re-deployment or loss of staff or any staff

Part 145 Sample Exposition - 2.0 September 2020

Page 33
change having impact on the approval. These changes must be captured and notified to CASA
according to the criteria specified in the MOE 1.9.

 Summary indication of the total number of staff inclusive of all the staff categories
listed below.
The number of staff declared in this MOE must remain consistent unless otherwise notified /
approved by CASA as applicable via the AMO change management procedures (MOE sections
1.9, 1.10, 1.11).

(CASR regulation 42.310, paragraph 145.A.10, 25 and subparagraphs 145.A.70 (a)8,
10, and 15 of the Part 145 MOS refers)

This section is required to describe each of the facilities, in some detail, at which the
organisation intends to carry out maintenance. All the facilities need to be identified in this Part.
This will provide a clear picture of what CASA is being asked to assess and approve. All
facilities and their locations must be covered; however, a different emphasis can be placed on
each site dependent on the level of work undertaken.
The system of protection against weather, dust and other airborne contaminants (paint, smoke
etc...), heating/air conditioning, lighting, noise protection, safety system (limited accesses, fire,
staff security etc...) should be described either in the facility layout diagrams or in associated
text.

 Principal Address:
 This is the main location where the organisation provides maintenance services.
These details may also be included on the MOE cover page.
 The Principal address of the main location will be included in the CASA approval
certificate.
 Registered Business Address:
 This is the official head office address of the business. (The official address if
registered with Australia Securities and Investments Commission (ASIC)).
 Postal (surface mail and e-mail) Address:
 Clearly identify the postal address of the maintenance organisation to be used by
CASA for formal mail communication.

Part 145 Sample Exposition - 2.0 September 2020

Page 34
  In addition, to ensure an efficient and stable communication channel between
CASA and the maintenance organisation, it is recommended to include a “generic”
email address. The generic email address prevents additional administrative
changes as it remains independent should respective persons in charge leave the
company.

1.7.1 Base maintenance facilities

This section should describe specific requirements for Base Maintenance facilities in
accordance with the Part 145 MOS. These include:

 Hangar accommodation:
 Include Hangar layout(s) specifying the various allowed aircraft parking
configurations, as applicable to the aircraft type(s) included in the scope of
approval.
As a minimum, this information must clarify for any approved Hangar, the maximum number of
aircraft which can be accommodated at the same time (including any Base and/or Line
Maintenance activity), the maximum number of aircraft which can undergo Base Maintenance
at the same time and which is the biggest aircraft type which can be accommodated.

 Aircraft access equipment/platforms/docking

 Specialised workshops
 Environmental provisions
 Office accommodation for: (planning, technical records, Quality, technical reference
area, Storage, etc)
 Storage of aeronautical products / materials etc (only to identify storage location(s), the
storage facility requirements / conditions is covered in MOE sections 2.3, 2.7).
Note: The Hangar visit plan may be referenced from here, however due to its association and importance with
the man-hour planning requirements it is expected to be in the MOE section 2.21.

1.7.2 Line maintenance facilities

(Paragraph 145.A.75 (c) of the Part 145 MOS refers)

This section should describe facilities utilised at each location, to provide evidence that the
facilities are appropriate for the maintenance services to be provided at that location and are
appropriate for the scope of Line Maintenance as approved for the organisation.

 Hangar availability (specify if rented or owned)

For line maintenance of aircraft, Hangars may be required. In this case the availability of a
suitable Hangar should be demonstrated, particularly in the case of inclement weather for
minor scheduled work and lengthy defect rectification.
In case the Hangar facility is not available at the location, this must be clearly stated. As
general guidance in such case, the scope of work of the particular line station should not
exceed the weekly check. Inclusion of other minor scheduled maintenance tasks is subject to
detailed assessment that they can be carried out safely to the required standards at the
designated line maintenance station.
This MOE subsection links with MOE section 6.3 List of line maintenance locations and
addresses.

Part 145 Sample Exposition - 2.0 September 2020

Page 35
1.7.3 Aeronautical product maintenance facilities
This section should describe the workshop facilities in adequate detail for the scope of work in
accordance with the requirements of the Part 145 MOS.

 Engine / APU / Aeronautical Product workshop accommodation:

 Include facility layout(s) and with the similar considerations for the requirements
specified at MOE subsection 1.7.1 (e.g. Equipment areas, environmental
provisions, office and storage accommodation, specialised work areas etc)
consistent for the scope of approval.

1.7.4 Layout of premises

(Subparagraphs 145.A.70 (a) 8 and 15 of the Part 145 MOS refers)

This section should show floor plans and diagrams of the facilities, including proposed
accommodation of aircraft and aeronautical products, workshops, storage facilities and office
accommodation.
Where the accommodation is not owned by the organisation, as in the case of a Hangar where
space is rented or shared, proof of tenancy/access may be required and CASA may wish to
have this included in an Appendix or Supplement to the MOE.

1.8 Scope of maintenance services to be provided

(CASR paragraph 145.025 (3) (b) and regulation 145.070, section 145.A.10 and
subparagraphs 145.A.70 (a) 9 and 10 and Appendix I of the Part 145 MOS refers)

An AMOs approved scope of maintenance will be broadly defined by the Approval Certificate
and detailed within the Exposition approved by CASA. The Approval Certificate will list the main
locations, Classes, Ratings and their limitations for the Maintenance Services that the AMO is
approved to provide.
The Part 145 MOS requires the AMO to specify in its Exposition the scope of maintenance it
has the capability to perform at each of its locations. This section should also relate to MOE
sections 1.7 and 6.3 facilities and locations in such a way that it can be clearly seen which
specific scope of work is performed at each location.
Limits to the scope of approval ratings will apply to small organisations. (refer to Appendix I of
the Part 145 MOS)

The following considerations to define the maintenance level:

 The limitation relative to the maintenance checks/tasks must use the naming
convention as referenced in TC Holder data (e.g. MRB/MPD).
 In case of unforeseen maintenance such as but not limited to major repairs and
modifications that is not already described within this chapter, the maintenance
organisations should contact CASA.
 The maintenance level is intended to specifically identify the maximum extent of
routine maintenance allowed. Defect rectification, out of phase tasks, SB, deferred
items, etc., are considered included in the line and/or base maintenance scope of
work, subject to the decision making process to be described in the MOE section 2.27
production planning procedure. Maintenance organisations not intending to perform
defect rectification must specify as such. (example provided in this MOE subsection
1.8.1 table 2 above).
 Limitations to unscheduled line maintenance or base maintenance capability must be
stated (e.g. excluding structural repairs, excluding landing gear replacement, etc.)
 In the case of line maintenance, a clear definition of the line maintenance as
applicable to the particular organisation, taking into account the defined parameters
included in MOS AMC 145.A.10 and the actual capability held.

This list(s), whether included to or separately referenced from the MOE, is an integral part of
the approval. This means that it is approved (directly by CASA on initial approval, via approval
of a significant change or by the organisation through a procedure which has been previously
approved by CASA where the change to the list would not constitute a significant change (refer
to MOE sections 1.9, 1.10, 1.11).

1.8.4 Specialist maintenance

(CASR subparagraph 145.025 (3) (b) (ii) and Part 145 MOS Appendix I refers)

1.8.4.1 NDT with D1 Rating

When the organisation intends to perform NDT tasks and release such tasks using a CASA
Form 1, the rating D1 is necessary. Under the D1 rating, the capability to perform maintenance
is determined by the “NDT method” listed in the approval certificate schedule, regardless of the
specific aircraft, engine or aeronautical product which is subject to the NDT inspection method.
This section must further define the limitations to the approval schedule.
Example:
Rating Limitation Detail of limitation
D1 Liquid penetrant (PT) techniques in accordance with the AMO NDT Manual
Magnetic particle(MT) reference XXXXX, approved by the appointed /
Eddy Current ( Nominated responsible NDT level 3
Ultrasonic (UT)
Radiography (RT)
Thermography (IRT)
Shearography (ST)

 For D1 rating, include:

 in column Rating: D1
 in column Limitation: specify the NDT method(s) (amend as necessary)
 in column Detail of Limitation: reference to approved AMO NDT manual for
specific techniques / capabilities – (also refer to MOE sections 1.3.6 and 3.14 for
further details).
1.8.4.2 NDT without D1 Rating (“in the course of maintenance”)

Part 145 Sample Exposition - 2.0 September 2020

Page 41
When the organisation intends to perform NDT tasks under another approved rating (e.g. as
part of the maintenance carried out on aircraft under rating A1, engines under rating B1,
aeronautical products under a C rating) the NDT tasks are considered done in the “course of
maintenance”.

 In this case, even if the organisation does not need to hold a D1 rating, the various
NDT methods applied during maintenance must be listed in this subsection (e.g. the
Example table above as the basis without the D1 rating). When the organisation holds
a fixed NDT capability (e.g. personnel, facility, equipment) at different specific sites or
workshops, the information must be stated.
It must be noted that the same requirements in place for being approved under the D1
rating remain applicable.
1.8.4.3 Welding with D2 Rating
When the organisation intends to perform Welding tasks and release such tasks using a CASA
Form 1, the rating D2 is necessary. Under the D2 rating, the capability to perform maintenance
is determined by the “Welding process(es)” listed in the approval certificate schedule,
regardless of the specific aircraft, engine or aeronautical product which is subject to the
Welding process(es). This section must further define the limitations to the approval schedule.
Example:
Rating Limitation Detail of limitation(s)
Type / PMG
D2 Type 1 - Gas welding. / Group #  Specify parent metal groups
Type 2 - Braze welding. / Group # (PMG) applicable for each
Type 3 - Manual Metal Arc Welding. type

 For D2 rating, include:

 in column Rating: D2
 in column Limitation: specify the Welding Type(s) (This may include combination
parent metal groups - amend as necessary)
 in column Detail of Limitation: specify further detail to clarify approval scope
capability (refer to MOE section 3.14 for further details).
1.8.4.4 Welding without D2 Rating (“in the course of maintenance”)
When the organisation intends to perform Welding tasks under another approved rating (e.g. as
part of the maintenance carried out on aircraft under rating A1, engines under rating B1,
aeronautical products under a C rating) the Welding tasks are considered done in the “course
of maintenance”.

 In this case, even if the organisation does not need to hold a D2 rating, the various
Welding process(es) applied during maintenance must be listed in this subsection (e.g.
the Example table above as the basis without the D2 rating). When the organisation
holds a fixed Welding capability (e.g. personnel, facility, equipment) at different specific
sites or workshops, the information must be stated.

Part 145 Sample Exposition - 2.0 September 2020

Page 42
 It must be noted that the same requirements in place for being approved under the D2
rating remain applicable.
1.8.4.5 Other Specialised Activities without D rating (“in the course of maintenance”)

 Each specialised maintenance tasks such as but not limited to composite repairs,
painting, machining, NDI, must be detailed in this subsection.
Note: The “D” rating is not applicable to all specialist maintenance as specified by subparagraph 145.A.30(f)3
of the Part 145 Manual of Standards.

 These specialised services / maintenance task activities must be detailed for each
approved site and workshop
It has to be noted that those specialised maintenance tasks may need to be carried out under
specific conditions (e.g. aircraft painting is considered to be a base maintenance task and
therefore an Aircraft base maintenance scope of approval is required in addition to listing such
activity in this section).

1.8.5 Fabrication in the course of maintenance

(Section 145.A.43 of the Part 145 MOS refers)

If an AMO has been approved to maintain aircraft or aeronautical products under CASR Part
145, it may only fabricate a part for an aircraft or aeronautical product covered by its certificate
of approval, and only if it has the capability to fabricate the particular part with respect to
appropriate facilities, tools, equipment, data and trained and competent employees.
If the AMO is required to fabricate parts in the course of maintenance, this section of the
Exposition will specify such applicability and be subject to the conditions referenced and
specified in the MOE section 2.9 procedures to be used to ensure all requirements of section
145.A.43 of the Part 145 MOS are complied with.
The MOS AMC 145.A.43 provides the principles and conditions for the extent of fabrication in
the course of maintenance for the provisions within the Part 145 MOS.

1.8.6 Maintenance away from the approved locations

(Paragraph 145.A.75 (b) of the Part 145 MOS refers)

Only if applicable, this subsection should make reference to the fact that the organisation may
perform works away from the approved locations, subject to the condition specified in MOE
section 2.23 (specific maintenance procedure for works away from the approved locations).
It must be noted that this privilege, is approved by CASA based upon the ability of the Quality
and Safety Systems to deal adequately with the Part 145 requirements. The ability of those
systems cannot therefore be demonstrated at entry control for initial approvals or for recently
approved organisations where only limited surveillance has occurred.
Therefore, subject to the CASA surveillance cycle and/or events whereby the AMO can
sufficiently demonstrate ability of their quality and safety systems, only then can CASA
consider assessment of proposed procedures for this AMO privilege to control aircraft
unserviceability’s at any location.
Exceptions may be considered on a case by case basis whereby the CAMO and contracted
AMO have a justified need to work outside the approved locations immediately after initial
approval.

Significant changes to the organisation require approval by CASA in accordance with CASR
regulation 145.055. Significant changes are defined in CASR subregulation 145.010(2).
This section should set out the procedure that the AMO must follow for making significant
changes to the organisation. In particular, it should set out how the changes are initiated and
assessed, how applications are made, how the organisation ensures that the change is fully
incorporated and who within the organisation is responsible for managing these changes. (SMS
management of change)

1.9.1 Notification of proposed changes

The organisation must notify CASA of any proposal to carry out any of the changes listed below
before such changes take place. (refer MOE subsection 1.11.3)
The use of a table is recommended as per the example below which should be customised as
applicable to the scope of activity of the maintenance organisation.
In addition, this procedure should detail:

 When to notify the change for CASA approval

 What documentation is to be submitted for CASA approval (e.g. MOE, procedures,
CASA forms etc)
 Safety risk assessment for change / record for the changes
 Cases when an internal audit by the Quality system is required
 Who in the maintenance organisation should be involved with the management of the
change(s)
 Who in the maintenance organisation is responsible for notification to CASA.

For any change of approval applications, the organisation should manage the safety risks
related to any changes to the organisation. The SMS management of change documented
processes should identify external and internal changes that may have an adverse effect on
safety. The organisation should make use of existing hazard identification, risk assessment and
mitigation processes. The safety risk assessment documentation should be made available to
CASA upon request.
In addition to addressing any safety risks, the change management must ensure continued
compliance with the Part 145 requirements. To ensure this is achieved and subject to the
extent of proposed change(s) for approval, satisfactory compliance with all applicable Part 145
requirements may be achieved and demonstrated by the organisation conducting an internal
pre application audit. The audit report should be recorded in accordance with MOE Part 3 and
the documentation made available to CASA upon request.
The intent of the internal audit ensures that the organisation has verified its compliance with the
Regulations. This permits the organisation to demonstrate the extent to which the applicable
requirements are complied with, and to provide assurance that the organisation systems are
established to a level that is sufficient to perform the scope of maintenance activities.
The requirement to have such internal audit carried out as part of any application for change,
should be addressed in a procedure under this MOE section 1.9.

(CASR 145.060 and subparagraphs 145.A.70 (a) 12 and 145.A.70 (b) of the Part 145
MOS refers)

The organisation should manage the safety risks related to any changes to the organisation.
The management of change should be a documented process to identify external and internal
changes that may have an adverse effect on safety. It should make use of the organisation’s
existing hazard identification, risk assessment and mitigation processes.
Changes to the organisation and Exposition that are not significant changes may be made by
the AMO in accordance with CASR 145.060 without prior approval by CASA. However, those
changes not requiring prior approval by CASA must be managed and notified to CASA in
accordance with a procedure which has been approved by CASA.
The relevant MOE procedure must define both the scope of such changes and describes how
such changes will be managed and notified.
For initial applicants, the scope of this procedure may be limited by CASA for the first period of
operation. An extension of such a limited scope may be considered later; depending on the
compliance and safety performance of the organisation and in particular, on its capability to
manage the safety risks related to changes.
This section should set out the procedure that the AMO must follow for making changes to the
organisation that are not significant changes. In particular, it should set out the scope of such
changes, how they are assessed, how applications are made, how approvals are given, how
the organisation ensures that the change is fully incorporated, how the organisation notifies
CASA and who within the organisation is responsible. (SMS management of change)

Part 145 Sample Exposition - 2.0 September 2020

Page 47
1.10.1 Notification of changes
The organisation must notify CASA of any organisational and MOE related changes that are
defined as changes that are not significant which the organisation has approved procedures to
manage. (refer MOE section 1.11.3)
The use of a table may be developed to define the scope of such changes, (basic example
below) which should be customised as applicable to the scope of activity of the maintenance
organisation.
In addition, this procedure should detail:

 When to notify the change to CASA

 What documentation is to be submitted to CASA (e.g. MOE, procedures, CASA forms
etc)
 Cases when a Safety risk assessment of the change is required
 Cases when an internal audit by the Quality system is required
 Who in the maintenance organisation should be involved with the management of the
change(s)
 Who in the maintenance organisation is responsible for notification to CASA.

1.11 Exposition
(CASR paragraph 145.015(2)(c) refers)

1.11.1 Providing employees with exposition

(CASR 145.080 refers)

This section should set out how the organisation ensures employees have access to the parts
of the Exposition that relate to their duties and responsibilities, and who is responsible for this.

1.11.2 Keeping the exposition up-to-date and compliant

(Paragraph 145.A.70(b) of the Part 145 MOS)

This section should identify how the organisation ensures that the Exposition is kept up to date
and it complies with requirements of CASR 42, 145 and Part 145 MOS in relation to its content
and who is responsible for this.
The Quality Manager is responsible for reviewing the MOE on a regular basis and amending if
necessary, this includes the associated procedure manuals, and the submission of
amendments to CASA (proposal of Significant change(s) requiring CASA approval and
notification of changes which are not significant if the organisation has an approved procedure).
The MOE and associated documents and lists must be amended as necessary to remain an
up-to-date description of the organisation. (Refer also MOE subsection 1.11.3 and as
applicable MOE sections 1.9, 1.10)
1.11.2.1 Compliance to applicable regulations and associated material
The quality system is responsible to assess any revision of the applicable regulations. Manual
of Standards and associated compliance and guidance material for their impact on the
organisation’s MOE procedures/lists etc. CASA expects that traceable evidence is in place to
record implementation of this process to be confident that the organisation’s MOE
procedures/lists finally comply with any applicable requirement.

 Description of the process in place to control amendment due to applicable regulation

changes etc, assess their impact on the organisation’s procedures/lists and when
applicable revise those procedures/lists within any established entry into force date.
 (Optional) this paragraph may be used to list the applicable regulations and associated
material, together with their revision status, which are considered for the development
of the current revision of the MOE and associated procedures/lists.

1.11.3 Changes to AMO exposition

(CASR 145.050, 145.060 and subparagraphs 145.A.70(a) 12 and 145.A.70 (b) of the
Part 145 MOS refers)

A Part 145 maintenance organisation approval includes approval of the MOE, whether in a
single or several document structure / format (Refer to the Section A: Explanatory Material,
subsection "General Guidance - 0.7 Structure and content of MOE".
Part 1 of the MOE contain details which include management, organisation, manpower
resources, facilities, scope of maintenance services and change management (organisation

Part 145 Sample Exposition - 2.0 September 2020

Page 49
and MOE) and the other Parts whether included or reference from Part 1 for the various
procedures, manuals, lists etc all form the basis of the approval. Any significant change will
affect the conditions under which the organisations approval was issued and has been allowed
to continue.
This section should set out how the MOE is managed, how any proposed change to the
Exposition is initiated, distinction between significant changes and changes that are not
significant, who is responsible for assessing the proposed change to determine whether the
change needs to be approved by CASA, or whether it may be made in-house. The section
should set out the procedures for making applications for changes to CASA or if applicable, the
procedures for making changes in-house by the AMO. It should also identify the individual who
is responsible for incorporating the change in the Exposition once it is approved.
1.11.3.1 MOE Amendment
Exposition amendment procedure:

 Person responsible for amending the Exposition.

 Definition of amendments (Significant / Not Significant) to the Exposition and related
approval process.

MOE amendments may be initiated from any part of the organisation but must be monitored for
compliance with Part 145 requirements by the Quality Manger who should also be the focal
point for submitting amendments to CASA. It is recommended to only make submissions from
one source within the organisation.

 Definition of criteria / control for new Issue and/or Revision (refer to subsection C3.
Amendment record, Examples 1 and 2).
 The record of the Part-145 approval certificate and approval of the MOE and
subsequent amendment needs to be described:
 Approval letter from CASA as applicable
 Part 145 approval certificate and/or appendix amendments following change of the
scope of activity and/or change of the locations and/or a new issue of the MOE
etc.
1.11.3.2 Associated procedures, lists and forms
The minimum documentation / procedures / lists etc to be considered are all those required by
MOS 145.A.70(a) identified in MOS AMC 145.A.70, which are therefore an integrally part of the
Exposition. In addition, the MOE together with the associated procedures must cover all
aspects of carrying out maintenance, including the provision and control of specialised services
and lay down the standards to which the organisation intends to work.
This procedure should address:

 Summary table of MOE associated documents, procedures and lists:

The summary of documents comprising the complete Exposition may be by means of
a tabled list such as the Example but may also include a diagrammatic illustration to
show their inter-relation.

* When a procedure is approved to manage changes, which are not significant changes, it is
important that the MOE section 1.10 and subsection 1.11.3.3 describes the limits of the
approval privilege. Even if a document is subject to an organisational approval for changes
which are not significant, in the case of a change affecting the scope of work this document
must be approved by CASA (e.g. amending the capability list to add a P/N belonging to a new
C rating)
** when the organisation develops second level procedures (for example to describe the details
of maintenance processes in each area/workshop), those procedures must be collected into a
separate manual (e.g. associated procedures manual) also listed in this table.

 Definition of criteria for new Issue and/or Revision

1.11.3.3 Approval process

 CASA approval:
 The procedure should at least describe the process followed to achieve approval
from CASA.
 If applicable - organisation approval of changes which are not significant changes (see
MOE section 1.10):
 the list of documents etc for which the organisation has an approved procedure to
manage (list applicable documents in the table provided in paragraph 1.11.3.2).
 For each of the above mentioned documents, the procedure must at least include:

Part 145 Sample Exposition - 2.0 September 2020

Page 51
  definition of amendments (Significant / Not Significant). In particular, the defined
scope of such changes for each document that can be approved by the
organisation (may be directly identified in the table provided in paragraph 1.11.3.2,
refer to the example).
 the person responsible for the internal organisational approval of the related
documents (may be directly identified in the table provided in paragraph 1.11.3.2,
refer to the example).
 the notification of such internal organisational approval (not significant) to CASA.
 the record of such organisational approval.

The scope and approval of this procedure to manage changes that are not significant may be
limited for the initial organisation approval. This is based upon substantiating the ability of the
Quality and Safety Systems to deal adequately with the Part 145 requirements which cannot be
demonstrated at the time of the initial approval. (MOE section 1.10 refers)

1.11.4 Direction by CASA to change expositions

(CASR 145.065 and 145.085 refers)

This section should set out the how the AMO incorporates changes to its Exposition to comply
with a direction given by CASA. The individuals responsible for this should be identified.
Subject to the significance of such direction, this subsection may also refer to the MOE
sections 1.9, 1.10 and the above subsections 1.11.2, 1.11.3 for incorporating and managing
such MOE changes.

Part 145 Sample Exposition - 2.0 September 2020

2 Part 2: Maintenance Procedures
(CASR 42.310,CASR 145.070 and paragraph 145.A.65 (b) of the Part 145 MOS
refers)

This part should set out, in detail, how the AMO provides the maintenance services it is
approved and required to provide in order to ensure that it meets its obligation under
CASR Parts 42, 145 and Part 145 MOS.
It is acceptable to refer to other documents and manuals of the AMO in order to prevent the
Exposition from becoming unmanageably large. However, if this is done, then the other
documents and manuals become subject to the same requirements and controls as the
Exposition e.g. CASA approval and change management.

2.1 Supplier evaluation and subcontract control procedure

(Subparagraphs 145.A.65 (c) 5, 145.A.70 (a) 16 and145.A.75 (a) of the Part 145 MOS
refers)

The use of the following terms is made in this subsection to standardise the nomenclature for
the possible various providers of aeronautical products/parts/materials and providers of
maintenance services.
Provider Any source of aeronautical products, material,
maintenance services external to the maintenance
organisation. Any provider may fall in one of the
following category:

 Supplier
 Contracted organisation
 Subcontracted organisation.
Supplier Any source providing aeronautical products,
standard parts or materials to be used for
maintenance. Possible sources could be: Part-145
organisations, Part-21 organisations, operators,

another approved maintenance organisation.

The list of contracted organisations are included in

the MOE section 6.4 required by MOS
145.A.70(a)16.
Subcontracted organisation An organisation, not itself appropriately approved to
Part-145 that carries out aircraft line maintenance
or minor engine maintenance or maintenance of
other aircraft aeronautical products or a specialised
service as a subcontractor for an organisation
appropriately approved under Part-145, refer to
MOS 145.A.65(c)5; 145.A.75(a).

The list of subcontracted organisations are included

in the MOE section 6.2, required by MOS
145.A.70(a)16.

 Definition of Suppliers of materials, standard parts, aeronautical products:

 Sources of supplies (e.g. constructor, original equipment manufacturer (OEM),
distributor approved by the manufacturer, retailer, airline, ...).
 Types of supplies (e.g. aeronautical products, consumables, standard parts,
materials, etc.).
 Definition of Contracted organisations:
 Sources of services (e.g. CASA Part 145 approved maintenance organisation and
related approved ratings).
 Types of services (e.g. specialised work, line maintenance, aeronautical product
maintenance, etc.).
 Definition of Subcontracted organisations:
 Sources of services (non- Part 145 approved organisation and related
qualification).
 Types of services (e.g. specialised work, line maintenance, aeronautical product
maintenance, etc.).

2.1.2 Monitoring the suppliers

Supplier evaluation may depend on different factors such as the type of aeronautical product,
whether or not the supplier is the manufacturer of the aeronautical product, the TC holder or a
maintenance organisation, or even specific circumstances such as aircraft on ground. This
evaluation may be limited to a questionnaire from the Part-145 organisation to its suppliers, a
desktop evaluation of the supplier’s procedures, an on-site audit or combination, if deemed
necessary.

 Initial approval of each type of provider:

 Selection processes
 Internal acceptance process
 Issuance of the internal authorisations (e.g. scope of authorisation, validity, ...)
 Producing the list of suppliers, contracted organisations and subcontractors
 Internal distribution of the list – access / authorisation of computerised list.
 Monitoring of the lists of each type of provider versus internal authorisation:
The list of suppliers are managed under the control of the Quality Department.

  Incoming inspection results, audit results, possible internal limitation
 Assessment of the service provided
 Updating of the list
 Withdraw of the internal authorisation, when applicable.
 Management of the purchase orders according to the approved providers.
 Records of providers information:
 Files
 Duration / location
 Type of documents (Certificates, audit reports, incoming inspection results, …).

2.1.3 Monitoring the contracted organisations

A process similar to the case of monitoring the suppliers may be adopted.

 Initial approval of each contracted organisation.

 Monitoring of the lists of each type of contracted organisation versus internal
authorisation (refer to MOE section 6.4).
 Management of the purchase orders according to the approved contracted
organisation.
 Records of contracted organisations information.

2.1.4 Monitoring subcontractors

The acceptance and monitoring process must comply with MOS 145.A.65(c)5; and 145.A.75.
(a), also refer to Part 145 AMC/GM.

 Initial approval of each subcontractor:

 Pre-audit before approval and inclusion in the internal audit plan.
 Approved maintenance organisation expertise and procedures to control the sub-
contractor.
 Supervision of the inspection and release from the sub-contractor.
 Contract to allow access of CASA to the sub-contractor.
 Monitoring of the lists of each type of subcontractors versus internal authorisation
(refer to MOE section 6.2).
 Management of the purchase orders according to the approved subcontractors;
 Records of subcontractors information.

2.2 Receipt / inspection / acceptance of aeronautical products

(CASR Subpart 42.E and section 145.A.42 of the Part 145 MOS refers)
This section should describe the procedures for receiving aeronautical products, parts,
materials etc from outside the organisation, such as for example from suppliers, contracted
organisations, etc.

2.2.1 Classification and definitions

 Serviceable aeronautical products
 Unserviceable aeronautical products (CASR 42.460)
 Standard parts (CASR 42.445)

Part 145 Sample Exposition - 2.0 September 2020

Page 55
  Raw and Consumable material (CASR 42.455)
 Unsalvageable aeronautical products (CASR 42.465)
 Suspect unapproved parts (CASR Subpart 42.E.4).

2.2.2 Aeronautical product / Part / Material certification.

This subsection is expected to identify the certification / release documents required for the
acceptance of each type of aeronautical product / part / material depending on their status
(new/used). It is recommended to develop a table listing all the cases, for easy reference to
receiving inspection personnel.
Advisory Circular AC 20-03 Identification and management of aeronautical products - provides
additional information and guidance.
Example - New Parts:
Status "New"
Type: Aeronautical Product / Part / Material Expected Documentation
Aeronautical products Option 1: CASA Form 1.

Option 2: Other NAA's equivalent release

documents for new parts as acceptable under the
CASR 1998: such as for example (not exhaustive):

Example:
 FAA Form 8130-3 with status “new”
 TCCA Form One with status “new”.
Standard Parts / Materials Option 1: when the part/material is purchased
(raw materials and/or consumables) directly from the manufacturer, the Certificate of
Conformity issued by the manufacturer is expected.
For Standard Parts mentioned in CASR 42.445
and Materials mentioned in CASR 42.455 and Option 2: when the part/material is purchased thru
their eligibility refer to applicable definitions: a third party supplier (e.g. distributor, operator,
maintenance organisation, etc.) the documentation
• Dictionary Part 1 of CASR 1998 . accompanying the part/materials must contain:
• For eligibility to fit Standard Parts and use
Materials refer to CASR 42.015 Definitions.  conformity certification to the
part/material applicable
standard/specification
 identification of the manufacturing
source
 Identification of the supplier source.

For Option 2, the information above may be

included in one single Certificate of Conformity
(CoC) issued by the supplier (containing cross
reference to the manufacturer CoC) or be
composed by more documents, such as for
example the CoC issued by the manufacturer plus
a statement from the supplier source.

In any case, the manufacturer CoC must be made

available upon request.

Part 145 Sample Exposition - 2.0 September 2020

Example - Maintained Parts
Status "Maintained"
Type: Aeronautical Product / Part Expected Documentation
Aeronautical products Option 1: CASA Form 1: (CASR 42.H.4 - CRS).

Option 2: Other NAA's equivalent release

documents for parts maintained outside Australia
as acceptable under the CASR 1998: such as for
example (not exhaustive):

Example:
 FAA Form 8130-3 with status “new”
 TCCA Form One with status “new”.
Components CASA Form 1: (CAR 42WA - RTS) - Control of
parts for aircraft operated under CAR 1988.

Depending on the type of components, the organisation must additionally describe the specific
requirements applicable to APMA / PMA parts, Life Limited parts, used parts, etc.

2.2.3 Receiving inspection procedure

 Receiving inspection For Aeronautical Products / Materials/ Standard Parts received
from external sources
The procedures for acceptance of aeronautical products, standard parts and materials must
have the objective of ensuring that the aeronautical products, standard parts and materials are
in satisfactory condition and meet the organisation’s requirements. These procedures need to
be based upon incoming inspections.
 physical inspection of aeronautical products, standard parts and/or materials:
o verify the general condition of aeronautical products / parts and their
packaging in relation to damages that could affect their integrity
o verify that any applicable shelf life of the aeronautical products has not
expired
o verify that items are received in the appropriate package in respect of the type
of aeronautical products: e.g. correct ATA 300 or electrostatic sensitive
devices packaging, when necessary
o verify that the aeronautical products have all plugs, caps, blanks, covers etc
appropriately installed to prevent damage or internal contamination. Care is

2.2.4 Installation of aeronautical products/standard parts/materials

 Procedure for verification prior to installation of aeronautical products/standard
parts/materials
Aeronautical products, standard parts and materials must only be fitted when specified in the
applicable ICA/maintenance data. This could include parts catalogue (IPC), service bulletins
(SB), aircraft maintenance manual (AMM), etc. So, the installation of a aeronautical product,
standard part and material can only done after checking the applicable maintenance data.
This check must ensure that the part number, modification status, limitations, etc., of the
aeronautical product, standard part or material are the ones specified in the applicable
ICA/maintenance data of the particular aircraft or aeronautical product (i.e. IPC, SB, AMM,
CMM, etc.) where the aeronautical product, standard part or material is going to be installed.
The organisation must establish procedures to ensure that this check is performed before
installation
 Verification the applicable maintenance data specifies the particular aeronautical
product, standard part or material.
 Verification of satisfactory condition and appropriate document for installation.

Part 145 Sample Exposition - 2.0 September 2020

Page 58
  Verification that, an aeronautical product is eligible to be fitted when different
modification and/or airworthiness directive configuration may be applicable.
 Verification prior to installation of standard parts on an aircraft or component (e.g.
traceability, applicable standard as per ICA/maintenance data requirement).
 Verification prior to use any raw or consumable material on an aircraft or
component (e.g. shelf life / due dates, applicable specification as per
ICA/maintenance data requirement).

identification data and any information useful to define actions necessary to be taken. Such
information must state, as applicable, in-service times, maintenance status, preservation
status, failures, defects or malfunctions reported or detected exposure to adverse
environmental conditions, and if the part was installed on an aircraft involved in an accident or
incident. Measures should be provided to prevent unintentional separation of this tag from the
part.
 Standard parts
 Raw and Consumable material
 Unsalvageable components
 Mutilation before disposal

Part 145 Sample Exposition - 2.0 September 2020

Page 59
Mutilation must be accomplished in such a manner that the part become permanently unusable
for their original intended use. Mutilated parts should not be able to be reworked or
camouflaged to provide the appearance of being serviceable, such as but not limited to re-
plating, shortening and rethreading long bolts, welding, straightening, machining, cleaning,
polishing, or repainting etc..
When in agreement with the aeronautical product owner, the part is disposed of for legitimate
non-flight uses, such as training and education aids, research and development, or for non-
aviation applications, mutilation may not be appropriate. In such case, the part may be marked
permanently indicating that it is unsalvageable, the original part number or data plate
information removed and a record kept of the disposition of the component.

(b) In the case of operator/customer provided data, the AMO has direct access to TCH/OEM to
verify the revision status of the documentation provided by the customer (e.g. typical example
would be that the TCH/OEM provides this information freely available in its website). In
addition, the conditions specified below apply:
1. A contract is in place detailing the responsibilities for ensuring the availability, the
update of the maintenance data from the customer/operator and formal authorisation
for the use of such data.
2. The maintenance data is available at the time of the audit by CASA.
3. The MOE section 1.8 is limited as necessary (to the specific customer/operator) and
an application is done according to MOE section 1.9 when the contract is
terminated/cancelled because this may directly affect the approval.

2.8.2 Documentation / maintenance instructions issued by the maintenance

organisation
This procedure if applicable should describe the various types of maintenance instructions
which may be developed by the maintenance organisation starting from the maintenance data
(e.g. AMM, CMM, etc.).
It has to be noted that the MOE section 2.12 only describes the templates and their use in the
maintenance process, while this MOE section 2.8 is intended to cover the procedure on how to
ensure that maintenance data are correctly transcribed into work instructions.

response)
 Modification control — (requirements and approval).

2.12 Maintenance documentation in use and its completion

(CASR subparagraph 42.310(1) (a) (i) and paragraph 145.A.45 and 145.A.55 of Part
145 MOS refers)

It is recommended to structure this section in separate subsections as indicated below with

clear differentiation between each individual rating in the scope of work (e.g. aircraft, engines,
aeronautical products, specialised services).

2.12.1 Templates in use to record maintenance

This procedure should identify the process of issuing and updating all the various templates in
use by the maintenance organisation to record maintenance, such as work sheets, job cards,
non-routine cards, deferred items, etc.
With regards to job cards and work sheets the MOE section 2.12 only describes the templates
and their use in the maintenance process, while the MOE section 2.8 is intended to cover the
procedure on how to ensure that maintenance data is correctly transcribed into work
instructions.

 Identification of the templates in use to record maintenance.

This procedure may refer to the MOE section 6.1 where the forms and templates in use by the

Part 145 Sample Exposition - 2.0 September 2020

Page 65
maintenance organisation are included.

 Analysis and implementation of Manufacturer data revisions.

 Initial approval and revision of the template.

2.12.2 Composition of the work package

This procedure must describe the composition of a standard work package as applicable to the
scope of work of the organisation (e.g. for aircraft maintenance will be routine work cards, non-
routine cards, ADs, SBs, MEL, deferred items, coordination (tally) sheet, maintenance
certifications and certificate of release to service, etc.)

 List of maintenance documents which build up a standard work package (e.g. front
page with General information, list of tasks required, work cards, associated work
orders, expected CRS…)
 Assembly of work packages for issue to maintenance activity
 Worksheets for non-routine task
 Assembly of completed work package for certification
 Control and use of customer supplied work card/worksheets.

2.12.3 Completion of maintenance documentation

This procedure must describe the completion of each of the documents identified in the
previous subsection. This may be done by reference to MOE section 6.1 where the related
sample document is included together with its related filling / completion / user instructions.

 Process of declaring a task not applicable including conditional tasks

 Process of recording test results and dimensions
 Process of recording specific tooling / equipment on task (MOS 145.A.55(a)2) (e.g.
complement control out of tolerance / calibrated tools - MOE section 2.5)
 Process of recording materials/parts replaced together with the related traceability to
the accompanying documents
 Record and management of additional works
 Record and management of deferred items
 Process to correct a maintenance record incorrectly entered during the performance of
maintenance. This process cannot be done after CRS issue
 Worksheet / work card completion and maintenance sign-off / performance of
maintenance certification / independent inspection verification
 procedure to ensure correct completion of customer provided work cards (e.g.
training on customer paperwork, etc.)
 Use of personal stamps
 Authorised personnel - stage / task completion - Sign-off policy:
Example - Summary table for tasks sign-off / maintenance certification / CRS policy
“Authorised personnel” means qualified / competent personnel (e.g. Mechanics etc.) formally
authorised by the maintenance organisation approved under Part-145 to sign for (sign-off) the
stage / task of work they performed. “Authorised personnel” are not necessarily “certifying staff”
A “Sign-off” is a statement by the competent person performing the work, that the stage / task
has been correctly performed. A sign-off relates to one step in the maintenance process and is
therefore different from the certifying staff issued with a certification authorisation to perform as
Part 145 Sample Exposition - 2.0 September 2020
Page 66
applicable task Maintenance Certification / CRS. E.g. In the case of aircraft base maintenance,
B1, B2, certifying staff as applicable, must ensure that all relevant tasks or inspections have
been carried out to the required standard and performed maintenance certifications before the
category C certifying staff issues the aircraft CRS.
The procedure must clearly indicate when a task is to be considered signed-off and by which
mean (e.g. use of personal stamp, use of signature, combination of stamp plus signature, etc.).
The sign-off policy is established to assign clear responsibilities for the performance of
allocated maintenance tasks, even when a task comprises of multiple sign-offs by more than
one person (e.g. complex tasks / large structural repair) prior to appropriate staged and final
task maintenance certifications.
The “authorised personnel” performing and signing for the stage / task is responsible for their
work.
The use of a sign-off summary table is recommended which must be consistent to the
procedures in MOE section 2.24 “Procedure to minimise the risk of multiple errors and
preventing omissions” and to the job descriptions identified within the maintenance organisation
Exposition (e.g. certifying staff in MOE section 3.5, mechanics in MOE section 3.13, qualifying
inspectors in MOE section 3.12, etc.).

plus the associated CRS in the aircraft technical logbook system must be kept on records by
the maintenance organisation.
 Copy of detailed records and associated repair and modification data
 Release documents of aeronautical products, standard parts installed and
consumable / raw materials used
Where the release documents are not included with the associated maintenance records the
organisation must demonstrate traceability is available in the maintenance records to the
release documents and that they can be retrieved at any time for all the period to which the
records retention requirements apply.
In the case of release documents related to aircraft aeronautical products, the
customer/operator agreement is necessary where those documents are only traceable but not
included with the maintenance records provided to the customer/operator.

 Format of the maintenance records (System):

 Paper and/or
 Computer system and related backup.
 Records storage conditions (ensure protection from damage, destruction, fire, flood etc
fire extinguisher system, fire detection) and retrieval of records (paper or computer
based).
 Control of access to records (paper and / or computer based records).
 Lost or destroyed records (reconstruction and CASA acceptance). This procedure
should only be proposed to CASA in case of the actual need arises.

Part 145 Sample Exposition - 2.0 September 2020

Page 68
  Retention of records:
 Periods
 Methods and security (identification, legibility and archiving and protection from
interference, tampering etc).
Minimum records retention period is two years from the date the aircraft or aeronautical product
to which the work relates was released by the maintenance organisation. Ensure all documents
which relate to the maintenance record are retained for the same period to substantiate the
record.

 Procedure for control and commitment that all retained maintenance records covering
the retention period must be distributed to the last owner or customer of the respective
aircraft or aeronautical product in case the maintenance organisation terminates its
operation.

  Need to complete a maintenance work order which leaves the aircraft / engine /
aeronautical products in non-approved configuration (e.g. CRS of an aircraft
where the maintenance organisation is only ordered to remove an engine).
 Need to issue a CRS for a maintenance check flight, where an STC has been
incorporated which is not yet approved (e.g. parts installed in “prototype status”,
maintenance performed using data pending approval, etc.) AMC 42.420(5)(a)(i).
 The specificities of CASA Form 1. This procedure needs to at least address the
following issues:
 The address to be recorded in the CASA Form 1 “Block 4” is the principal address
(main location) which is reflected in the first page of the CASA Approval
Certificate. However, to allow the identification of the maintenance site where the
CASA Form 1 is issued (in the case this is different from the main location), the
organisation needs to ensure a system is in place to retrieve the information of the
maintenance site where the CASA Form 1 was issued, starting from the Form
tracking number of the CASA Form 1 “Block 3”.
 Describe the Form tracking numbering system of CASA Form 1 demonstrating a
unique number is used.
 Describe an identification system which enables tracking the location where the
maintenance has been released to service.

2.21 Man-hours planning versus scheduled maintenance

(Paragraph 145.A.30 (d) and section 145.A.47 of Part 145 MOS refers)

 Maintenance man-hour plan (taking into account also maintenance activities carried
out outside the scope of the Part-145 approval).
 Reviewed at least every 3 months and updated when necessary.
 Covering all staff (e.g. certifying staff, inspectors, mechanics, planners, quality
auditors, etc.).
Particular attention must be given to the situation when the same person is acting with different
roles during a particular maintenance check (e.g. a person who is acting at the same time as
aeronautical product certifying staff and mechanic staff during particular aeronautical product
workshop maintenance, etc.). In such cases the man-hour plan for the particular maintenance
check should take into account this aspect to ensure the person is allocated enough time to
carry out the necessary activities required for each of the different roles he/she undertakes and
appropriate consideration is given to human performance limitations.

 Hangar visit plan versus man-hour plan.

The "Hangar visit plan" must be made available to demonstrate sufficiency of Hangar space to
carry out planned base maintenance. The relationship between the Hangar visit plan and the
man-hour plan must be described and include other approved activities.

 Notification to the Quality Manager and Accountable Manager of deviations exceeding

25% between the work load and the man hour availability.

2.22 Control procedure for critical tasks

(CASR division 42.D.5 and subparagraph 145.A.65 (b) 8 of Part 145 MOS refers)

Suggested subject headings:

 Independent verification — inspection procedures

 Critical task procedures and control
 Critical task list

2.22.1 Critical maintenance tasks

 Definitions for “critical control system maintenance" / "critical maintenance task”:

Critical control system maintenance, for an aircraft:

means maintenance carried out on the aircraft control system for the aircraft that, if not carried
out correctly, may result in a failure, malfunction or defect of the system that will endanger the
safe operation of the aircraft; and does not include optional dual flight control maintenance.

Aircraft control system, for an aircraft, means the system of the aircraft by which the flight path,
attitude or propulsive force of the aircraft is changed.

 Procedure to identify a list of “critical control system maintenance tasks” defined by the
maintenance organisation (e.g. tasks that affect aircraft flight path, attitude such as
flight control adjustments, tasks that affect the propulsive force of the aircraft including
installation of engines/propellers/rotors, this may also consider tasks that affect flight
path, attitude stability such as autopilot, fuel transfer systems etc.)
 Person responsible to amend the list
 Data sources used to identify and amend the list of “critical maintenance tasks”
(TCH data, occurrence reporting, results of audit, feedback from training, etc.).

This procedure is required to ensure that critical control system maintenance tasks are
reviewed to assess the impact on safe operation of the aircraft. The list of tasks should be
customised to the scope of work of the organisation and may contain any other identified
critical tasks peculiar only to certain aircraft or aeronautical products. This list may be included
into a separate document under the control of the Quality Manager

The list of tasks should be subject to continuous evaluation and when necessary amended by
the organisation as the result of maintenance errors investigations, audit, TCH data analysis,

Part 145 Sample Exposition - 2.0 September 2020

Page 76
etc.
When the operator/customer defines its own list of critical control system maintenance tasks
and any other tasks they deem critical, the effective independent inspection tasks to be carried
out are the independent inspections required by the Part-145 MOE and the tasks required by
the customer/operator.

2.22.2 Error-capturing methods

This paragraph should identify and detail the management of each possible error-capturing
method in use by the organisation subject to the defined maintenance task.

 Identification of the error-capturing method(s) to be used:

 Independent inspection
 The planning method - different individuals for similar tasks in different systems
 Additional inspection (Re-inspection) - (limited to unforeseen cases when only one
person is available for similar tasks on more than one system on the same aircraft)
 Independent inspection procedure
This paragraph must address the requirements of Division 42.D.5 of CASR for independent
inspection.
 Definition of independent inspection
 Personnel authorised for the independent inspections (Independent Individual).
The qualification of this personnel. Reference can be made to applicable MOE sections such
as MOE section 3.5 Certifying employees.

 How to perform an independent inspection:

 What has to be checked (e.g. all those parts of the system that have actually been
disconnected or disturbed must be inspected for correct assembly, locking, full
and free range operating in the correct sense etc.).
 How a task requiring independent inspection is verified and recorded.
(Consistency with the MOE section 2.12 requirements for maintenance records completion
including stage / task sign-off, maintenance certifications / CRS.)

 Additional inspection (reinspection) procedure (limited to unforeseen cases when only

one person is available for similar tasks on more than one system on the same aircraft
MOS 145.A.65(b)8):

staff, trainees) is appropriately supervised and certified.

2.24.2 Procedure to minimise the risk of errors being repeated in identical

maintenance tasks compromising more than one system or function
 Criteria to define the identical maintenance tasks.
The objective of the procedure is to ensure no single person is required to perform a
maintenance task such as removal/installation or assembly/disassembly of several components
of the same type fitted to more than one system on the same aircraft or component during a
particular maintenance check, whereby possible failure or malfunction could endanger the safe
operation of the aircraft.

2.24.3 Identification of methods in use to minimise the risks

 Planning method (only applicable to similar / identical maintenance tasks).
This subsection is intended for procedures describing how the planning method is used to
minimise the risk of errors being repeated in identical maintenance tasks by planning the
performance of the same task in different systems by different authorised individuals.

 A clear work order or contract has been agreed between the maintenance
organisation and the customer/operator to clearly establish the maintenance to be
carried out
 the requested maintenance remains within the approved scope of approval
 need of special facilities.

The main driver to determine whether the requested maintenance is within the scope of
approval, must be the content of the specific maintenance activity ordered. Additional tasks or
constraints may be also associated to the requested activity such as deferred items,
rectification of defects, inspection requesting skilled workers, qualification of the certifying staff,
environmental conditions, overall length of the tasks etc. Therefore a “decision making process”
is necessary to assess whether the content of the maintenance activity is within the scope of
approval. In addition, access to special facilities (e.g. Hangar for line maintenance, etc.) must
be part of the decision making.

 Verification that the maintenance work package job cards provided by the customer
can be is utilised by the maintenance organisation. In any case the organisation must
issue an internal work package as detailed in MOE section 2.12:

Part 145 Sample Exposition - 2.0 September 2020

Page 80
  Case 1: customer job cards to be used (with appropriate training).
 Case 2: work package to be developed and prepared by the maintenance
organisation based on the customer work order.
 Control of the availability and update of maintenance documents (list + MM / job
cards /…).
 Procedure for establishing all necessary resources are available before
commencement of work (e.g. Hangar (visit plan), manpower with required capabilities,
staff, facilities, tools, equipment, parts, documentation, etc.).
 Procedure for outsourcing contractors as necessary.
 Procedure for organising maintenance personnel and providing all necessary support
during maintenance.
 Consideration of human performance limitations (Circadian rhythm / 24 hours body
cycle...).
 Planning of all maintenance tasks (Including complex, critical, independent
verifications etc).

  Principles of annual audit procedure planning.
 Grouping of audits.
 Dates and timescales.
 Audit of the Quality system by an independent auditor, being either:
 A person employed by the maintenance organisation and working in another
department (e.g. production), or;
 A person contracted by the maintenance organisation (part-time basis or short
time contract based on the 145.A.30 (d) contracted personnel) to perform audits
on the quality system procedures. This case does not mean subcontracting the
quality system.
 Audit of contracted organisations / Subcontractors / suppliers, as applicable depending
to the monitoring criteria defined in MOE section 2.1.
 Scheduled audits and unannounced audits to be carried out during maintenance
including night shifts.
 Validation/internal approval of the audit program and management of changes to the
program
 Follow up of the audit program: scheduled, performed, audit report issued, open/close
– link with MOE section 3.3
 Company Audit Policy including compliance audit:
 Audit notification
 Audit reports (documents used, writer, issue, points checked and deviations noted,
deadline for rectification)
 Reference can be made to MOE section 3.3 detailing the process to manage
findings
 Allocation of resources to the audit (audit team, team leader, etc.)
 Principles when deviations are noted on a line of product
 Quality audit reports / retention
 Duration (At least duration of 2 years from the date of the findings closure) /
location
 Type of documents (notification, audit reports, check list, audit programs)
 An audit report must be raised each time a system audit is carried out describing
what was checked and the resulting findings against applicable requirements,
procedures and products.
Example:
The purpose of this example is to provide an acceptable audit plan (there is any number of
other acceptable working audit plans). The following criteria must be met:

 The audit plan is intended to monitor compliance with the applicable requirements and
at the same time review all areas of the organisation, where such requirements are
applicable.
 In order to achieve this objective, as a first element, the organisation needs to identify
all the regulatory requirements, AMC and CASA guidance material applicable to the
activity and scope of work under consideration, to allow the audit plan to focus on the
relevant subject matters. Each subject matter (e.g. facilities, personnel, etc.) should be
cross-referred with the relevant requirement and the related organisation procedure in
the Exposition, where the particular subject matter is described.

Part 145 Sample Exposition - 2.0 September 2020

Page 85
  As a second element, all functional areas of the organisation in which Part-145
functions are intended to be carried out, including subcontracting, need to be listed
with the objective of identifying the applicability of any subject matter in each functional
area.
 A matrix can be used (refer to TABLE 1 below), capturing the two above-mentioned
elements. This is intended to be a living document to be customised by the particular
organisation depending on its scope of work and structure. This matrix would
represent the overall compliance of the audit system and would need to be amended,
as necessary, based upon any change to applicable regulations, AMC and CASA
guidance material, organisation procedures and functional areas of the organisation
(e.g. change of the scope of work to include line maintenance, etc.).
 The audit plan (refer to TABLE 2 below), can be finally presented as a simplified
schedule, showing the operational areas of the organisation against a timetable to
indicate when the particular area is scheduled for audit and when the audit was
completed. The number of product audit and subcontractors audit directly depends on
the number respectively of product lines and subcontracted organisations in use. The
audit plan should also identify some unannounced audits during on-going maintenance
(including unannounced audits which also consider varying shift patterns, eg. Night
shift).
 The audit of each operational area will review all the subject matters which are
applicable to the relevant functional area. For each subject matter, the audit should
check that the particular Part-145 requirement is documented in the corresponding
Exposition procedure and that the Exposition procedure is effectively implemented in
the operational area subject to the audit. In addition, the audit should also identify any
practice/process implemented in the particular operational area which has not been
documented in any Exposition procedure.

3.10 Competence assessment of employees

(CASR 42.315 and Paragraph 145.A.30 (e) of the Part 145 MOS refers)

This MOE section 3.10 applies to all maintenance personnel involved and however defined in
the Part-145 AMO activities (management personnel, certifying staff, mechanics, inspectors,
quality auditor, engineering staff, production planning staff, store inspectors, tools
administrators, purchasers, etc.).
The qualification requirements to be assessed for each category of staff (as they differ between
staff categories) is expected to be found in the relevant MOE sections (e.g. MOE section 1.3 for
management personnel, MOE section 3.5 for Certifying employees, MOE section 3.7 for quality
auditor, MOE section 3.13 for mechanics, etc.).
The organisation should develop a procedure describing the process of competence
assessment of personnel. The procedure should specify:

 persons responsible for this process

 when the assessment should take place
 how to give credits from previous assessments
 how to validate qualification records
 means and methods to be used for the initial assessment
 means and methods to be used for the continuous control of competence including
feedback on personnel performance
 the aspects of competences to be observed during the assessment in relation to each
job function
 the actions to be taken when assessment is not satisfactory
 how to record assessment results.

For example, according to the job functions and the scope, size and complexity of the
organisation, the assessment may consider the following Example Table 3 below (the table is a
non-exhaustive list and should be developed accordingly):

 Management of competence assessment:

 Assessment procedures for initial, extension and renewal of an authorisation
(process/method used)
 Person responsible for this process on behalf of the organisation
 When the assessment takes place
 Assessors
 Commission / examination
 Actions to be taken when the assessment is not satisfactory.
 The competence assessment includes:

Part 145 Sample Exposition - 2.0 September 2020 Page 95

 APPROVED MAINTENANCE ORGANISATION

 Verification that all the applicable qualification requirements for the specific
category of staff as detailed in the relevant MOE section/job description are
satisfied (e.g. MOE 3.5 for certifying staff, etc.)
 Verification of the specified competences associated with job function (refer to
Example Table 3) and include verification of:
o Relevant knowledge skills and experience on the product/technical area as
applicable to the job function.
o Appropriate attitude towards safety and observance of procedures (including
organisational Drug and Alcohol Management Plans).
o Knowledge of the procedures (e.g. handling and identification of components,
MEL use, etc.) as applicable to the job function.
 The competence assessment is based on:
 Review of personnel records
 Interview
 Evaluation of competence “On-the-Job performance” and/or testing of knowledge
by appropriately qualified staff (e.g. in the case where the assessment is related to
a new activity for which the maintenance organisation is not yet approved such as
a new aircraft type, new products / parts, new maintenance level / scope, etc.),
 Assessment records:
 Location
 Type of documents
 Clear identification of the scope of the assessment (initial, extension or renewal of
a Part-145 individual certification authorisation). This means for example:
Example:

 For aircraft certifying staff, which is/are the category(s) (e.g. B1 line maintenance
certifying staff, B1 base maintenance certifying staff, C base maintenance certifying
staff, A line maintenance certifying staff, etc.) and which is/are the aircraft type (s)
being assessed for endorsement in the authorisation (initial or extension of privileges).
 For aeronautical products certifying staff, which is/are the rating(s) (e.g. C14, C6, C5,
etc.) and the specific aeronautical products associated to each rating (e.g. Landing
Gears P/N, Battery P/N, etc.) being assessed for endorsement in the authorisation
(initial or extension of privileges).
 For quality auditor, which is the scope of the auditor authorisation (e.g.
system/procedures or product audit).
 Etc.
 Procedure to take credit of experience/training for new maintenance personnel joining
the maintenance organisation (ref. MOS GM 145.A.35(f)).
 Procedure to identify and assess the need for additional training for the various
categories of maintenance personnel, when applicable to the scope of approval of the
organisation. (E.g. TCH - ICA requirements for adherence to tasks such as EWIS /
FTS CDCCL) (Continuation training requirements are identified within the relevant
MOE sections for the various categories of personnel.)

3.12 Qualifying inspectors

(Paragraph 145.A.30(e) of the Part 145 MOS refers)

This section is dedicated to the qualification and authorisation of the “inspectors” which
undertake inspection functions and sign-off the related task(s).

Part 145 Sample Exposition - 2.0 September 2020 Page 98

 APPROVED MAINTENANCE ORGANISATION

 Identification of the various types of inspectors in the maintenance organisation

The various types of “inspector” personnel, as applicable to the organisation, need to be
addressed (e.g. aircraft inspector, aeronautical product inspector, engine inspector, store
receiving inspector, etc.). Clear differentiation is expected for each different ratings in the scope
of work (e.g. aircraft, engines, aeronautical products, specialised services).
It is recommended that a roster listing all maintenance personnel formally authorised to sign-off
/ certify as applicable for tasks as “inspectors” is available in the maintenance organisation
under the control of the Quality Manager.
They may be authorised:
Example:

 As aeronautical product/engine inspectors, in order to sign-off / certify for the tasks

performed under supervision (e.g. work performed by trainees).
 As aeronautical product/engine inspectors, in order to sign-off / certify the independent
inspection tasks.
 As store incoming inspectors, to perform and attest the receiving inspection of
aeronautical products / materials as per MOE section 2.2 procedure.

Aircraft/aeronautical product/engine inspectors are not authorised to issue a certificate of

release to service for aircraft or aeronautical product or engine, unless he/she are also holding
a “certification authorisation for issue of CRS”.
In the aircraft maintenance environment if the inspectors function does not correspond to the
B1, B2 certifying staff function a further inspection stage is necessary by the B1, B2, as
applicable for task maintenance certification. B1, B2 certifying staff, as applicable, must ensure
that all relevant tasks or inspections have been carried out to the required standard before the
category C certifying staff issues the certificate of release to service.
When the staff member is holding more than one authorisation (e.g. mechanic, inspector and
certifying staff), the different authorisations must be clearly distinguished. A person may be at
the same time:
Example:

 mechanic on the A320(CFM56), B777 (GE90) and ERJ-170 (GE CF34)

 inspector on the A320(CFM56) and B777 (GE90)
 holding a certification authorisation as certifying staff only for the B777 (GE90).

Experience, training and competence requirements:

 Aeronautical and practical experience

 General training (human factor, MOE, standard practices, when identified FTS,
CDCCL, EWIS etc)
 Specific training requirements applicable to the scope of activity (aeronautical product,
aircraft, engine, specialist service, store etc.)
 Authorisation type (define) and requirements for initial issue, extension (scope of
authorisation / limitations), renewal, withdrawal of the authorisation (revoking)
procedures
 Continuation training procedures including:

3.13 Qualifying mechanics

(Paragraph 145.A.30(e) of the Part 145 MOS refers)
This section refers to the different specialities of mechanics (e.g. airframe mechanics,
powerplant mechanics, avionics, sheet metal workers, cabin, fuel, engines, painters, welders,
cleaners, aeronautical products, NDT staff, composites, line maintenance, etc...), as applicable
to the organisation. Those personnel authorised by the maintenance organisation approved
under Part-145 to sign for stage / tasks that they have personally performed. Consistency must
be ensured with the maintenance documentation completion and certification requirements
described in MOE sections 2.12, 2.15. An authorised mechanic is not authorised to issue a
maintenance certification or CRS release to service for aircraft or aeronautical product or
engine or NDT, unless he/she is also appropriately qualified and holding an applicable
“certifying staff certification authorisation”.

 Identification of the various types of mechanics in the maintenance organisation.

It is recommended that a roster / list of listing all maintenance personnel formally authorised to
sign for stage / tasks as “mechanics” is available in the maintenance organisation under the
control of the Quality Manager.
When the staff hold more than one authorisation (e.g. mechanic, inspector and certifying staff),
the different authorisations must be clearly distinguished.
A person may be at the same time:
Example:

 mechanic on the A320(CFM56), B777 (GE90) and ERJ-170 (GE CF34)

 inspector on the A320(CFM56) and B777 (GE90)
 holding a certification authorisation as certifying staff only for the B777 (GE90).

Clear differentiation is expected for each different rating in the scope of work (e.g. aircraft,
engines, aeronautical products, specialised services)

 Experience, training and competence requirements.

 Aeronautical and practical experience.
 General training (human factor, MOE, standard practices, when identified FTS,
CDCCL, EWIS etc).
 Specific training requirements applicable to the scope of activity (aircraft, engine, etc.)

 Authorisation type (define) and requirements for initial issue, extension (scope of
authorisation / limitations), renewal, withdrawal of the authorisation (revoking)
procedures.
 Continuation training procedures including:
 Training program (MOE and associated procedures, PART 145, human factors,
specific technical requirements, …)
 Technical training
 Duration, intervals.
 Retention of records:
 Duration / location
 Type of documents.

The competence assessment process for issuance, extension, renewal of the Part 145
Authorisation is expected to be described in the MOE 3-10 “Competence Assessment”.

3.14 Qualification procedure for specialist maintenance such as

non-destructive testing, welding…and various specialised
activities such as painting, machining…etc
(Paragraphs 145.A.30(e) and (f) of the Part 145 MOS refers)

This section refers to the qualification of personnel performing specialist maintenance as

defined in the MOS 145.A.30(f) and any additional specialised services staff / tasks requiring
defined qualification standards and competences.
The section applies to all the specialist maintenance and additional specialised services within
the scope of approval capabilities identified in MOE subsection1.8.4 (e.g. NDT, Welding,
painting, machining, NDI etc).
It is recommended to structure this section to provide qualification requirements for each group
of specialist maintenance / specialised services staff in separate subsections.
The recognised NDT standards require that an NDT written practice must be in place to define:

 The qualification and authorisation of NDT staff to meet the requirements of the
recognised standards. (Refer to MOS AMC 145.A.30(f).).
 The specific technique(s) for each NDT method used in the maintenance organisation.

For the purpose of Part-145 the following document is required to address the NDT written
practice requirements:

 A procedure detailing the qualification and authorisation of the NDT staff to be

included directly in the MOE section 3.14.
 When a separate document to the MOE is utilised, the document must be associated
to the MOE to be referred as “AMO NDT manual” only detailing the technical
compliance of NDT activities/techniques under the control and approval of the
responsible NDT level 3 to be referred in the MOE section 1.8. In addition, the related
approval process is to be described in the MOE section 1.11.
