1. General (Rev. 1)
A. Statement of Purpose
(1) This manual has been reviewed and accepted by the FAA. Additionally, this
manual contains data that has been approved in a manner acceptable to the
FAA administrator.
(2) This manual provides maintenance and overhaul procedures for use in
propeller repair stations by personnel that are trained and experienced with
Hartzell Propeller Inc. products.
(a) This manual does not provide complete information for an inexperienced
technician to attempt propeller overhaul without supervision.
(3) This manual is intended to be the primary source of maintenance and overhaul
information for the applicable Hartzell propeller/component models.
(a) Propeller models addressed in this manual may be Type Certificated by
the FAA, or may be experimental. Experimental parts must not be installed
on a Type Certificated propeller. Always use the current illustrated parts
list for the assembly of any propeller. Always refer to the aircraft Type
Certificate (TC) or Supplemental Type Certificate (STC) to determine
installation eligibility of any propeller. If installation eligibility is not
identifiable, an additional installation approval, such as FAA form 337 field
approval or Supplemental Type Certificate may be required. If in doubt,
contact Hartzell Propeller Inc. Product Support.
(b) Information published in Service Bulletins, Service Letters, Service
Advisories, and Service Instructions may supersede information published
in this manual. The reader must consult active Service Bulletins, Service
Letters, Service Advisories, and Service Instructions for information that
may have not yet been incorporated into the latest revision of this manual.
(4) This manual makes reference to other Hartzell Propeller Inc. manuals
that provide important details for procedures such as anodizing, penetrant
inspection, and overhaul procedures for hub units.
(5) Where possible, this manual is written in the format specified by
ATA iSpec 2200.

B. Item References
(1) Item references throughout the text in this manual refer to item numbers in
the Illustrated Parts List chapter of this manual. The item numbers appear in
parentheses directly following the part name. Only the item base number will
appear in the text of the manual. Item base numbers and the alpha variants of
the base numbers will appear in the illustrated parts list. There are two reasons
for the use of alpha variants:
(a) A part may be superseded, replaced, or obsoleted by another part. For
example, the pitch change block unit (105733) that is item 320 was
superseded by the pitch change block unit (105733-1) that is item 320A.
(b) An Illustrated Parts List may contain multiple configurations. Effectivity
codes are used to distinguish different part numbers within the same list.
For example, one configuration may use a piston (B-2419) that is
item 80, yet another configuration uses a piston (104256) that is
item 80A. Effectivity codes are very important in the determination of parts
in a given configuration.

2. Reference Publications
A. Hartzell Propeller Inc. Publications
(1) Information published in Service Bulletins, Service Letters, Service Advisories,
and Service Instructions may supersede information published in this manual.
The reader must consult active Service Bulletins, Service Letters, Service
Advisories, and Service Instructions for information that may have not yet been
incorporated into the latest revision of this manual.
(2) In addition to this manual, one or more of the following publications are required
for information regarding specific recommendations and procedures to maintain
propeller assemblies that are included in this manual.

3. Personnel Requirements (Rev. 1)

A. Service and Maintenance Procedures in this Manual
(1) Personnel performing the service and maintenance procedures in this manual
are expected to have the required equipment/tooling, training, and certifications
(when required by the applicable Aviation Authority) to accomplish the work in
a safe and airworthy manner.
(2) Compliance to the applicable regulatory requirements established by the
Federal Aviation Administration (FAA) or international equivalent is mandatory
for anyone performing or accepting responsibility for the inspection and/or
repair of any Hartzell Propeller Inc. product.
(a) Maintenance records must be kept in accordance with the requirements
established by the Federal Aviation Administration (FAA) or international
equivalent.
(b) Refer to Federal Aviation Regulation (FAR) Part 43 for additional
information about general aviation maintenance requirements.

4. Special Tooling and Consumable Materials (Rev. 1)

A. Special Tooling
(1) Special tooling may be required for procedures in this manual. For further
tooling information, refer to Hartzell Propeller Inc. Illustrated Tool and
Equipment Manual 165A (61-00-65).
(a) Tooling reference numbers appear with the prefix “TE” directly following

5. Safe Handling of Paints and Chemicals (Rev. 1)

A. Instructions for Use
(1) Always use caution when handling or being exposed to paints and/or chemicals
during propeller overhaul and/or maintenance procedures.
(2) Before using paint or chemicals, always read the manufacturer’s label on
the container(s) and follow specified instructions and procedures for storage,
preparation, mixing, and/or application.
(3) Refer to the product’s Material Safety Data Sheet (MSDS) for detailed
information about physical properties, health, and physical hazards of any paint
or chemical.
6. Calendar Limits and Long Term Storage (Rev. 2)
A. Calendar Limits
(1) The effects of exposure to the environment over a period of time create a
need for propeller overhaul regardless of flight time.
(2) A calendar limit between overhauls is specified in Hartzell Propeller Inc.
Service Letter HC-SL-61-61Y.
(3) Experience has shown that special care, such as keeping an aircraft in a
hangar, is not sufficient to permit extension of the calendar limit.
(4) The start date for the calendar limit is when the propeller is first installed on an
engine.
(5) The calendar limit is not interrupted by subsequent removal and/or storage.
(6) The start date for the calendar limit must not be confused with the warranty
start date, that is with certain exceptions, the date of installation by the first
retail customer.
B. Long Term Storage
(1) Propellers that have been in storage have additional inspection requirements
before installation. Refer to the Packaging and Storage chapter of Hartzell
Propeller Inc. Standard Practices Manual 202A (61-01-02).

7. Component Life and Overhaul (Rev. 2)

WARNING: CERTAIN PROPELLER COMPONENTS USED IN NON-AVIATION

APPLICATIONS ARE MARKED WITH DIFFERENT PART
NUMBERS TO DISTINGUISH THEM FROM COMPONENTS
USED IN AVIATION APPLICATIONS. DO NOT ALTER THE
PART NUMBERS SHOWN ON PARTS DESIGNATED FOR NON-
AVIATION APPLICATIONS OR OTHERWISE APPLY THOSE PARTS
FOR USE ON AVIATION APPLICATIONS.
A. Component Life
(1) Component life is expressed in terms of hours of service (Time Since New, TSN)
and in terms of hours of service since overhaul (Time Since Overhaul, TSO).
NOTE: TSN/TSO is considered as the time accumulated between rotation
and landing, i.e., flight time.
(2) Time Since New (TSN) and Time Since Overhaul (TSO) records for the
propeller hub and blades must be maintained in the propeller logbook.
(3) Both TSN and TSO are necessary for defining the life of the component.
Certain components, or in some cases and entire propeller, may be "life
limited," which means that they must be replaced after a specified period of use
(TSN).
(a) It is a regulatory requirement that a record of the Time Since New (TSN)
be maintained for all life limited parts.
(b) Refer to the Airworthiness Limitations chapter in the applicable Hartzell
Propeller Inc. Owner's Manual for a list of life limited components.
(4) When a component or assembly undergoes an overhaul, the TSO is returned to
zero hours.
(a) Time Since New (TSN) can never be returned to zero.
(b) Repair without overhaul does not affect TSO or TSN.
(5) Blades and hubs are sometimes replaced while in service or at overhaul.
(a) Maintaining separate TSN and TSO histories for a replacement hub or
blade is required.

12. Definitions (Rev. 4)

A basic understanding of the following terms will assist in maintaining and operating
Hartzell Propeller Inc. propeller systems.

Term Definition
Annealed Softening of material due to overexposure to heat
Aviation Certified Intended for FAA or international equivalent type
certificated aircraft applications. A TC and PC number
must be stamped on the hub, and a PC number must be
stamped on blades.
Aviation Experimental Intended for aircraft/propeller applications not certified
by the FAA or international equivalent. Products marked
with an “X” at or near the end of the model number or
part number are not certified by the FAA or international
equivalent and are not intended to use on certificated
aircraft.
Beta Operation A mode of pitch control that is directed by the pilot rather
than by the propeller governor
Beta Range Blade angles between low pitch and maximum reverse
blade angle
Beta System Parts and/or equipment related to operation (manual
control) of propeller blade angle between low pitch blade
angle and full reverse blade angle
Blade Angle Measurement of blade airfoil location described as the
angle between the blade airfoil and the surface described
by propeller rotation
Blade Centerline An imaginary reference line through the length of a blade
around which the blade rotates
Blade Station Refers to a location on an individual blade for blade
inspection purposes. It is a measurement from the blade
“zero” station to a location on a blade, used to apply blade
specification data in blade overhaul manuals.
Note: Do not confuse blade station with reference blade
radius; they may not originate at the same location.
Blemish An imperfection with visible attributes, but having no
impact on safety or utility
Brinelling A depression caused by failure of the material in
compression

Page 13

 HARTZELL PROPELLER OVERHAUL MANUAL
113B

Term Definition
Bulge An outward curve or bend
Camber The surface of the blade that is directed toward the front
of the aircraft. It is the low pressure, or suction, side of the
blade. The camber side is convex in shape over the entire
length of the blade.
Chord A straight line distance between the leading and trailing
edges of an airfoil
Chordwise A direction that is generally from the leading edge to the
trailing edge of an airfoil
Co-bonded The act of bonding a composite laminate and
simultaneously curing it to some other prepared surface
Composite Material Kevlar®, carbon, or fiberglass fibers bound together with,
or encapsulated within an epoxy resin
Compression Rolling A process that provides improved strength and resistance
to fatigue
Constant Force A force that is always present in some degree when the
propeller is operating
Constant Speed A propeller system that employs a governing device to
maintain a selected engine RPM
Corrosion (Aluminum) The chemical or electrochemical attack by an acid or
alkaline that reacts with the protective oxide layer and
results in damage of the base aluminum. Part failure can
occur from corrosion due to loss of structural aluminum
converted to corrosion product, pitting, a rough etched
surface finish, and other strength reduction damage
caused by corrosion.
Corrosion (Steel) Typically, an electrochemical process that requires the
simultaneous presence of iron (component of steel),
moisture and oxygen. The iron is the reducing agent (gives
up electrons) while the oxygen is the oxidizing agent (gains
electrons). Iron or an iron alloy such as steel is oxidized
in the presence of moisture and oxygen to produce rust.
Corrosion is accelerated in the presence of salty water or
acid rain. Part failure can occur from corrosion due to loss
of structural steel converted to corrosion product, pitting,
a rough etched surface finish and other strength reduction
damage caused by corrosion.

 HARTZELL PROPELLER OVERHAUL MANUAL
113B

Term Definition
Corrosion Product A white or dull gray powdery material that has an
(Aluminum) increased volume appearance (compared to non-corroded
aluminum). Corrosion product is not to be confused with
damage left in the base aluminum such as pits, worm
holes, and etched surface finish.
Corrosion Product When iron or an iron alloy such as steel corrodes, a
(Steel) corrosion product known as rust is formed. Rust is an
iron oxide which is reddish in appearance and occupies
approximately six times the volume of the original material.
Rust is flakey and crumbly and has no structural integrity.
Rust is permeable to air and water, therefore the interior
metallic iron (steel) beneath a rust layer continues to
corrode. Corrosion product is not to be confused with
damage left in the base steel such as pits and etched
surface finish.
Crack Irregularly shaped separation within a material, sometimes
visible as a narrow opening at the surface
Debond Separation of two materials that were originally bonded
together in a separate operation
Defect An imperfection that affects safety or utility
Delamination Internal separation of the layers of composite material
Dent The permanent deflection of the cross section that is
visible on both sides with no visible change in cross
sectional thickness

not removed
Distortion Alteration of the original shape or size of a component
Edge Alignment Distance from the blade centerline to the leading edge of
the blade
Erosion Gradual wearing away or deterioration due to action of the
elements
Exposure Leaving material open to action of the elements

1. General (Rev. 1)
A. Propeller/Blade Model Designation
(1) Hartzell Propeller Inc. uses a model number designation system to identify
specific propeller and blade assemblies. The propeller model number and
blade model number are separated by a slash ( / ).
(a) Example: propeller model number / blade model number
(2) The propeller model number is impression stamped on the propeller hub.
(a) For additional information about the propeller model number designation
system, refer to the applicable Hartzell Propeller Inc. owner's manual.
(3) The blade model number is impression stamped on the butt end of the blade,
and also identified by a label on the cylinder.
(a) For additional information about the model number designation system
for composite blades, refer to Hartzell Propeller Inc. Composite Blade
Overhaul Manual 135F (61-13-35).
(b) For additional information about the model number designation system for
aluminum blades, refer to Hartzell Propeller Inc. Aluminum Blade Overhaul
Manual 133C (61-13-33).

DESCRIPTION AND OPERATION 61-10-13 Rev. 52 Apr/23
 HARTZELL PROPELLER OVERHAUL MANUAL
113B

2. Operation
A. Compact Constant Speed Non-Feathering Propellers (-1 )
(1) Constant speed non-feathering propellers utilize oil pressure from an engine
mounted governor to move the blades into high pitch or reduced RPM. A spring
and centrifugal twisting moment of the blades moves them to low pitch in the
absence of governor oil pressure.
B. Constant Speed Aerobatic Propellers (-4)
(1) Constant speed aerobatic propellers utilize oil pressure from an engine
mounted governor to move the blades into low pitch to increase engine
RPM. Counterweights on the blade shanks move the propeller to high pitch
to decrease engine RPM. This arrangement is necessary because aerobatic
aircraft occasionally encounter situations where the engine is supplying little
or no oil pressure. If sufficient oil pressure for blade pitch control is lost at any
time, the propeller blade pitch will move to high pitch to avoid overspeeding.
Movement to high pitch occurs because the blade counterweights are no longer
opposed by hydraulic oil pressure. The blade counterweights are then free to
increase blade pitch toward high pitch.
(2) Constant speed aerobatic propellers utilizing an accumulator (HC-C3YR-1A)
work in the same manner as constant speed non-feathering propellers. Oil
pressure from an engine mounted governor moves the blades to high pitch or
reduced RPM. The centrifugal twisting moment of the blades moves them to
low pitch in the absence of governor oil pressure. During inverted flight or in
maneuvers which cause engine oil pressure to be less than the pressure from
the accumulator, a check valve allows accumulator oil to be supplied to the
governor to maintain the appropriate pitch and prevent overspeed.

3. Model Designation System

A. Propeller Model Designation
(1) Hartzell Propeller Inc. uses a propeller model number designation system to
identify specific propeller and blade assemblies. An example of a propeller
model number would be HC-C3YR-1RF/F8468A-6R, with the slash mark
separating the propeller designation from the blade designation.
(2) The propeller model number is impression stamped on the propeller hub. The
blade model number is impression stamped on the butt end of the blade, as
well as ink stamped or identified by a label on the camber side of the blade.
(3) Refer to Hartzell Propeller Inc. Application Guide Manual 159 (61-02-59) or the
applicable owner's manual for additional information about the model number
designation system.
B. Blade Shank Designation
(1) For more information about blade shank designs, refer to Hartzell
Propeller Inc. Aluminum Blade Overhaul Manual 133C (61-13-33) or Composite
Blade Overhaul Manual 135F (61-13-35).

4. R-flange Hub Substitution for K-flange Hub

A. Hub Substitutions
(1) Two similar flange designs have been used to mount Hartzell propellers to
Lycoming engines -- the K-flange and the R-flange. The flange type is part of
the propeller model designation system.
(2) Hartzell Propeller Inc. has been manufacturing an improved design of the
R-flange propeller hub for installation on K-flange and R-flange applications.
This permits the manufacturing of one flange shape without requiring the
Aircraft Type
Certificates to be changed to add additional propeller model designations.
(3) R-flange propeller hubs will fit and operate properly on K-flange engines;
however, K-flange propellers manufactured with the original hub design will not
fit on R-flange engines.
(4) If the replacement of the hub is required, the overhauling facility must make sure
that the propeller model designation, i.e., K or R, is correct according to the
aircraft type certificate. Overhaul facilities may reidentify R-flange hubs as
K-flange hubs (when required by the model designation) by restamping the hub
model designation.
(5) Converting an original design K-flange to an R-flange hub is not permitted.

5. Lightweight Compact Propellers

A. Description of a Lightweight Compact Propeller
(1) A lightweight compact propeller has a unique structure that is only compatible
with certain blade models.
(a) For example, a three-blade lightweight compact propeller uses
9 hub clamping bolts instead of 15 hub clamping bolts that are
used for a compact hub.

(a) Obtaining a measurement outside the specified tolerance at any point of
measurement is cause for retirement of the part when a minimum of two
measurements are taken.
(b) Alternately, take eight evenly spaced measurements, unless specified
differently.
1 Obtaining a measurement outside the specified tolerance on three
or more measurements is cause for retirement of the part when eight
measurements are taken (two of eight measurements may be out of
specified tolerance).
2 This alternate method may not be used to accept a diameter that has
obvious damage beyond repairable (serviceable) limits.
(2) When measuring the diameter of a part with a three point measuring
instrument, take one measurement. A measurement outside the specified
tolerance is cause for retirement of the part.
B. Decimal Places
(1) Inspect the part features to the number of decimal places specified. If three
decimal places are specified, inspect the part to three decimal places only.

threaded fasteners is dependent upon proper torque application.
(a) Vibration can cause an incorrectly tightened fastener to fail in a matter of
minutes.
(b) Correct tension in a fastener depends on a variety of known load factors
and can influence fastener service life.
(c) Correct tension is achieved by application of measured torque.
(2) Use accurate wrenches and professional procedures to make sure of correct
tensioning.
(3) For the torque values to use when assembling a Hartzell Propeller Inc.
propeller, refer to Table 8-1, "Torque Values" in this chapter.
(4) When an adapter is used with a torque wrench, use the equation in Figure 8-1

6. Two Bladed Propeller Improvements

A. Two Bladed -1, -1A, and -1B Propeller Models
(1) The part lists for propeller models specified in this illustrated parts listing are of
the latest configurations produced by Hartzell Propeller Inc. Some models were
produced as -1 or -1A models (Example: HC-C2YK-1). Improvements were
made in the production of these propellers and are denoted by the -1B
(Example: HC-C2YK-1B). The improvements included a new spring, pitch
change rod, pitch change fork, and cylinder. The -1 and -1A models are not
obsolete; however, replacement parts may not be available. The -1B model
propellers are identical to -1 or -1A models except for substituting the parts as
listed in Table 10-1.
B. Two Bladed -1( ) and -1( )F Propeller Models
(1) Improvements were made in the production of two-bladed propeller models
in the form of the F-knob blade. Propeller models using blades with the
strengthened pitch change knob are denoted by the addition of an "F" at the

7. Three Bladed Propeller Improvements

A. New Hub Part Numbers
(1) Improvements were made in the production of three-bladed propeller models
in the form of an improved three-bladed compact propeller hub. Improved style
hubs have new part numbers and are identifiable by the suffix letter "B" at the
end of the hub serial number and the propeller serial number. The improved
style hubs are visibly different from previous hubs due to material added to the
forging in the blade retention area.
B. Three Bladed -1( ) and -1R( ) Propeller Models
(1) Hartzell Propeller Inc. currently produces hub units for only -1R( ) propeller
models. Hub units for the -1( ) propeller models are no longer procurable.
The hydraulic units of the -1( ) propeller models are incompatible with the
new -1R( ) propeller hub unit and must be changed if a new hub is installed.
By incorporating the new design hub and the accompanying hydraulic
components, the -1( ) propeller becomes a -1R( ) propeller and uses the parts
listed for the -1R( ) propeller.

8. A-3204 and A-3204-2 Set Screws

A. Removal of Set Screws from Stock
(1) A-3204 and A-3204-2 set screws with a certain hardness are to be removed
from field stocks.
NOTE: There have been several reports of broken A-3204 set screws. Two
contributing factors are the hardness and, in some screws, the depth
of the hex recess on the end of the screw (used for the internal
wrench) was aligned with the end of the external jam nut, which
combined to form a highly stressed area in the screw thread.
B. Identifying Set Screws Removed from Stock
(1) New screws with the desired hardness are color coded with a dull “olive green”
color. Any screws with “olive green” color are serviceable.
(2) Previous screws were a bright “bronze” color. Any screws of the “bronze”
color are not to be used and may be returned to Hartzell (via the source of
procurement) for credit or replacement.
