See  *  below
SAE propeller shaft size
Blade shank size
Number of blades
Major model type
*A dash number added to the propeller model designation indicates minor changes which do not affect
  eligibility.  If number is above 300 it also indicates the complete blade assembly and all of the rotating
  deicing system components.
NOTE 2. Blade Model Designation
A 2 J 17 M 3 -    8 W

Hamilton Standard shank size
Balance master, affects interchangeability but not
  eligibility.
*Blade models 2J17Z3 and 2J17AH3 are nickel plated.
Diameter limits shown are nominal diameters of the assembled propellers and do not include the +5/16,
-1/16 inch manufacturing tolerance permissible for propellers with steel blades.
NOTE 3. Pitch Control.  Eligible with Hamilton Standard constant speed control only.
NOTE 4. (a) Feathering.  Eligible with full feathering controls installed in accordance with the propeller
manufacturer's instructions.
(b) Reversing.  Eligible with reversing controls installed in accordance with manufacturer's
instructions.

NOTE 6. Interchangeable Blades.  Only blades listed in the same group of the following listed groups are
sufficiently similar aerodynamically and vibrationwise to permit interchangeability in the same
diameter without a flight test.  Blades with different model numbers should not be incorporated in
the same propeller, except as noted below, and reference should always be made to the ratings of
blades.
Group (a) 2J17B3, 2J17F3, 2J17H3, 2J17AG3, 2J17B3/SK31339** and 2J17F3/SK31339**
NOTE:  These blades can be used interchangeably in the same propeller provided
the prefix letter and cut-off dash numbers of the model designations are the same.
Group (b) 2J17Z3 and 2J17AH3  *(Nickel plated blades)
NOTE: These blades can be used interchangeably in the same propeller provided
the prefix letter and the cut-off dash numbers of the model designations are the
same.  Further, when specifically indicated on the pertinent aircraft specification,
the 2J17Z3 and 2J17AH3 blades can be used interchangeably in the same
propeller with those blades listed in Group (a) of NOTE 6 of this specification,
provided the 2J17Z3 or 2J17AH3 blades are used in pairs and installed in opposite
area, or one 2J17Z3 and one 2J17AH3 are used as a pair and installed in opposite
area, and that the prefix letters for opposite blades and the cut-off dash numbers for all
blades are the same.
**SK-31339 concerns reworking stiffener type blades to fairing type.
NOTE 7. Accessories.
(a) Propeller Deicing.
(1) Electric.  Eligible only with Hamilton Standard electrical deicing equipment installed
in accordance with the propeller manufacturer's instructions.
