(d) Maximum control pressure for all models: 400 psig
NOTE 4. (a) Feathering The -2 models incorporate feathering and unfeathering features.
(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
(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) Hard and soft alloy blades of the same model designation are interchangeable. (See NOTE 2)
(b) 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.

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, increas ed
RPM, altered ignition timing, electronic ignition, full authority digital engine controls (FADEC), or tuned induction or exha ust.
Also, any change to the mass or stiffness of the crankshaft/counterweight assembly is not approved by this list.
