The -4 models have stub counterweights and use oil to increase pitch. (see NOTE 4) (c) Governors must be approved as part of the aircraft installation regardless of manufacturer. (see NOTE 10) (d) Maximum control pressure for all models: 400 psig 3 of 5 P28EA Revision 10 NOTE 4: (a) Feathering The -1 and -4 models do not feather. The -2 models incorporate feathering and unfeathering features. The -1 and -2 models have counterweights. (b) Reversing Not applicable NOTE 5: Left-Hand Models The left-hand version of an approved model propeller 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 Blades with the suffix “N” in the basic model number may replace those without an “N” either individually or as a set. When the aircraft Type Certificate or Supplemental Type Certificate specifies blades with the letter “N” in the basic model number, the “N” character must be retained in all replacement blade models. For example: Blades without the “N” suffix may be replaced by “N” suffix blades. Blades with the “N” suffix may only be replaced by “N” suffix blades. Only blades listed in the same groups of the following listed groups are sufficiently similar aerodynamically and vibrationwise to permit interchangeability in the same diameter without a flight test. Group (1) R9349, R9350 (b) Propellers The HC-B3R( ) hub assembled with blades prefixed with the letter “R” may replace corresponding HC-93Z, HC-B3Z, and HC-B3W propellers fitted with corresponding blades, and are interchangeable with corresponding models HC-B3P. See table below (read across rows): Propeller models on TCDS P-891 may be replaced by corresponding models on TCDS P28EA HC-93Z30-2 HC-B3R30-2 Propeller models on TCDS P-907 may be replaced by corresponding models on TCDS P28EA HC-B3Z30-2 HC-B3R30-2 Propeller models on TCDS P2EA may be replaced by corresponding models on TCDS P28EA HC-B3W20-4 HC-B3R20-4 HC-B3W30-2 HC-B3R30-2 HC-B3W30-4 HC-B3R30-4 Propeller models on TCDS P28EA are interchangeable with corresponding models on TCDS P29EA HC-B3R20-4 HC-B3P20-4 HC-B3R30-1 HC-B3P30-1 HC-B3R30-2 HC-B3P30-2 (c) Governors (See NOTE 3) 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. (d) Ice Protection Systems Refer to Hartzell service Letter HC-SL-30-260 for ice protection system component interchangeability P28EA 4 of 5 Revision 10 NOTE 7: Accessories (See NOTE 10) (a) Propeller ice protection system (weight of ice protection system 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 manufacturer's 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 limi ted to, the addition of a turbocharger or turbonormalizer, increa sed 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.
