(b) 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.

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 standards.
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 Certification Branch Office 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 recommended overhaul periods.
