Models approved to the original certification basis include the following: HC-92ZF-1, -2, -6; HC-92ZK-1, -2, -6, -8; HC-92ZL-2; BHC-92ZF-1, -8 The following models were approved under Delegated Option Authorization Procedures of 14 CFR Part 21, Subpart J. Models added, updated or revised in accordance with 14 CFR Part 35 effective April 3, 1967 with amendments 35-1 and 35-2 include the following: BHC-92ZF-3 Date of application for Type Certificate: April 15, 1955. Production Basis: Production Certificate no. 10 NOTE 1: Hub Model Designation B HC- 9 2 Z F - 2 A L denotes left hand rotation Any other character denotes a minor change not affecting eligibility Denotes specific design features (see NOTE 4) -1: constant speed with counterweighted blades and 11.2 sq. in. piston area -2: constant speed and feathering with counterweighted blades and 11.2 sq. in. piston area -3: constant speed and reversing with counterweighted blades and 11.2 sq. in. piston area -6: constant speed with non-counterweighted blades and 23.0 sq. in. piston area -8: constant speed with non-counterweighted blades and 11.2 sq. in. piston area F denotes special flange with six 1/2” bolts and two 1/2” dowels on a 4” bolt circle K denotes SAE no. 2 flange with six 1/2” bolts and four 3/4” bushings on a 4-3/4” bolt circle L denotes SAE no. 2 flange with six 7/16” bolts and four 3/4” bushings on a 4-3/4” bolt circle Hartzell blade shank size (see NOTE 6) Number of blades Identifies basic design Hartzell Controllable Indicates dowel location with respect to centerline through blade sockets when viewing hub from flange mounting face (“F” flange hubs only) Blank: 90 and 270 deg. clockwise B: 30 and 210 deg. clockwise Page 3 of 6 P-892, Revision 20 NOTE 2: Blade Model Designation L 84 47 A - 3Q Number of inches cut off from basic diameter Q when used denotes special 1” x 90 deg. factory-bent tip for cutoff diameter A when following the dash number indicates a thinner and narrower tip R when used denotes specifically rounded tip for cutoff diameter * A denotes 0° sweepback * B or K denotes deicing boots N denotes shank modification (see NOTE 6) Any other character denotes a minor change not affecting eligibility Basic model or template Basic diameter in inches L when used denotes left hand blade * Some blades which use square or rounded tip shapes may not contain the letters “S” or “R” in their model designation. These characters are used to distinguish blades when two or more tip shapes are available at the dame diameter. Blades identified with an “A” following the model designation denote 0° sweepback (otherwise sweepback is 1°). Diameter limits shown are nominal diameters of the assembled propeller and do not include the + 1/8 inch manufacturing tolerance permissible for propellers with basic diameter less than 14 feet. NOTE 3: Pitch Control (a) Approved with Hartzell governors per drawings C-4770 and C-4772. Wt.: 4.5 lb. D - 1 - 4 Z Governor Model Designation L when used indicates left hand rotation Z when used indicates drive coupling type (see NOTE 6) Any other character denotes a minor change not affecting eligibility Minor adjustment not affecting eligibility Minor adjustment to obtain engine/propeller/governor compatibility Basic body and major parts modification (b) The -1, -2 and -3 models have counterweighted blades and use oil to decrease pitch. The -6 and -8 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 and Reversing (a) Feathering The -2 model incorporates feathering and unfeathering features. The -1, -3, -6 and -8 models do not feather. (b) Reversing The -3 model is approved for installation as a reversing propeller with appropriate reversing controls. 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) P-892, Revision 20 Page 4 of 6 NOTE 6: Interchangeability (a) Blades (1) 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. (2) 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 (a) 8447(N)-8 to -14, 8447A(N)-8 to -14 Group (b) 8447(N)-12A to -16A, 8447A(N)-12A to -16A Group (c) 8447(N)-12R to -16R, 8447A(N)-12R to -13R (b) Governors (See NOTE 3) (1) 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. (2) The Hartzell B-0 is the only model which is interchangeable with the Hamilton Standard 1M12 and 1Q12. Other Hartzell models are not interchangeable with any Hamilton Standard model without modification of the latter. (c) Propellers (See NOTES 1 and 2) (1) The following propeller models may be replaced by corresponding propellers listed in Type Certificate Data Sheet P16EA as indicated below. Propellers listed in this data sheet are not approved to replace propellers listed in P16EA. For example (B)HC-92W( ) models using blades with a “W” prefix may replace corresponding (B)HC-92Z( ) models using blades with no prefix.

(2) Approved with Hartzell fluid feed equipment on propeller models for which equipment is available. (b) Propeller deicing (weight of deicing system extra) (1) Approved with Goodrich electrical deicing kit 5EXXXX, 7EXXXX, 77-XXX, 67-XXX or 65-XXX when installed in accordance with Goodrich Report no. ATA 30-60-07. (2) Approved with Goodyear Ice Guards (electrical propeller deicer) when installed in accordance with instructions outlined in Goodyear Report no. AP-147 dated October 23, 1961. (3) Approved with ice protection equipment when listed on Hartzell type design data. (c) Propeller spinner (weight of spinner extra) Approved with Hartzell and other manufacturers’ spinners when listed on approved type design data. 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 c onfigurations on the engine type certificat e unless specifically stated otherwise. Modifications to the engine or airframe that alter the power of the engine models listed be low during any phase of operation have the potential to increase propeller stresses and are not approve d by this list. Such modi fications include, but are not limited to, the addition of a turbocharger or turbonormalizer, increased boost pressure, increas ed 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. Hub Blade Max. Dia. Min. Dia.
