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 limited to, the addition of a turbocharger or turbonormalizer, increased boost
pressure, increased compression ratio, increased RPM, altered ignition timing, electronic ignition, full authority digital
engine controls (FADEC), or tuned induction or exhaust. Also, any 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 strike.
Note 11: Special Limits
(a) Life Limits and Mandatory Inspections
(1) Airworthiness limitations, if any, are specified in Hartzell Manual 480.
