counterweighted blades and use oil to increase pitch. (See NOTE 4)
(c) Maximum governor output pressure: 350 psi for all propeller models
(d) All governors must be approved as part of the aircraft installation regardless of manufacturer. (See NOTE 10)
NOTE 4: Feathering The -1 models do not feather.
The -2 models incorporate feathering and unfeathering features.
Reversing Not applicable
Piston size The -2R model differs from the -2 model in that the -2R model has a piston area of 20.2 sq. in.
and the -2 has a piston area of 16.25 sq. in.

NOTE 5: Left-Hand Models
The left-hand version of an approved propeller model is approved at the same rating and diameter as listed for the
right-hand model. (See NOTES 1 and 2)
NOTE 6: Interchangeability
(a) Blades
(1) Blades with counterweights (having “C” prefix) can replace non-counterweighted blades on feathering
propellers (hub model suffix -2 or -2R) only, provided the air charge is reduced to 80 psi at 70°F.
Attached decal specifying air charge must be changed accordingly.
(2) Shot-peened blades may replace non shot-peened blades either individually or as a set (See NOTE 2)
(b) Propellers
“F” type propellers with large pitch change knobs are interchangeable with corresponding propellers
with the standard pitch change system. (See NOTES 1 and 2)
(c) Ice Protection Systems
Refer to Hartzell Service Letter HC-SL-30-260 for ice protection system component
interchangeability.
(d) Governors
Hartzell governors with a “Z” suffix in their model designation may be used interchangeably with
corresponding governors without the “Z”. For example, the F-6-24Z is a replacement for the F-6-24
and the F-6-24 is a replacement for the F-6-24Z.
NOTE 7: Accessories
(a) Propeller ice protection system (weight of ice protection equipment extra)
(1) Propeller models listed in this data sheet are approved for use with propeller ice protection equipment
listed in Hartzell Manual 159( ) or in other Hartzell type design data.
(2) All propeller ice protection equipment must be approved as part of the aircraft installation regardless
of manufacturer. (See NOTE 10)
(b) Propeller spinner (weight of spinner extra)
(1) Approved with Hartzell and other manufacturers’ spinners when listed on Hartzell type design data.
(2) All propeller spinners must be approved as part of the aircraft installation regardless of manufacturer.
(See NOTE 10)
NOTE 8: Shank Fairings Not applicable.

NOTE 9: Special Limits
Table of Propeller - Engine Combinations
Approved Vibrationwise for Use on Normal Category Single Engine Tractor Aircraft
The maximum and minimum propeller diameters that can be used from a vibration standpoint are shown below. No reduction
below the minimum diameter listed is permissible, since this figure includes the diameter reduction allowable for repair
purposes.
The engine models listed below are the configurations on the engine type certificate unless specifically stated otherwise.
Modifications to the engine or airframe that alter the power of the engine models listed below during any phase of operation have
the potential to increase propeller stresses and are not approved by this list. Such modifications include, but are not lim ited to,
the addition of a turbocharger or turbonormalizer, increased boost pressure, increased compression ratio, increased RPM, alte red
ignition timing, electronic ignition, full authority digital engine controls (FADEC), or tuned induction or exhaust. Also, a ny
change to the mass or stiffness of the crankshaft/counterweight assembly is not approved by this list.

NOTE 10: Propeller installation must be approved as part of the aircraft Type Certificate and demonstrate compliance with
the applicable aircraft airworthiness requirements.
Propeller models listed herein consist of basic hub and blade models. Most propeller models include additional
characters to denote minor changes and specific features as explained in NOTES 1 and 2. Refer to the aircraft
Type Certificate Data Sheet for the specific propeller model applicable to the installation.
Propellers with composite blades must be evaluated for bird impact resistance prior to approval on any type
aircraft. Hartzell Propeller must perform tests and/or analyses based on aircraft configuration and operating
conditions to determine the potential hazard as a result of a bird impact.
NOTE 11: Retirement Time
(a) Life Limits and Mandatory Inspections
(1) Airworthiness limitations, if any, are specified in Hartzell Manuals 115N, or 145( ).
(2) The propeller Certificate Management Certification Branch must evaluate the propeller
installation for each new aircraft installation to assess possible changes in the airworthiness
limitations.
NOTE 12: Special Notes
(a) Refer to Hartzell Manual no. 202( ) for overspeed and overtorque limits.
(b) Refer to Hartzell Service Letter HC-SL-61-61( ) for overhaul periods.
