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.

accordance with Hartzell specification H-S-2 or Hartzell Manual no. 133( ).
(2) Approved with Hartzell fluid feed equipment on propeller models for which equipment is available.

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.

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.
