This character is used to distinguish between two or more tip shapes available at the same diameter. Certain blades use “S” to denote shot peening of the exterior surface. (See Note 6) ** Diameter limits are nominal diameters of the assembled propeller. They do not include the + or – 1/8 inch manufacturing tolerance the FAA allows for propellers with a basic diameter of less than 14 feet. Note 3: Pitch Control (See Notes 4 and 10) (a) Approved with Hartzell governors per drawings C-4770, C-4771 and C-4772. Wt.: 4.5 lb.

The -1 models do not have 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 and -4 models do not feather. The -2 and -5 models incorporate feathering and unfeathering features. The -5 model is turbine oil compatible. Reversing Not applicable Piston size Piston area is 17.7 sq. in. except as noted in Note 1. Page 9 of 12 P25EA, Revision 35 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) Propellers (1) “F” type propellers with large pitch change knobs are interchangeable with corresponding propellers with the standard pitch change system. ( See Notes 1 and 2) (2) HC-C3YR models may replace corresponding HC-C3YK models. (See Note 1) (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. (c) Blades (1) Shot-peened blades may replace non shot-peened blades either individually or as a set (See Note 2) (2) N7605C( ) blades may replace N7605( ) blades either individually or as a set. N7605( ) blades may not replace N7605C( ) blades. (d) Ice Protection Systems Refer to Hartzell Service Letter HC-SL-30-260 for ice protection system component interchangeability. Note 7: Accessories (See Note 10) (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. P25EA, Revision 35 Page 10 of 12 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, altered 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. Hub Blade Max. Dia. Min. Dia.

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 113( ), 115N, 117( ) 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 overhaul periods.
