P-870 2 Production Basis Production Certificate No. 14 NOTE 1. Hub Model Designation 2 4 2 60 - 300 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 Inboard closure contour, does not affect eligibility Nominal reduction from basic diameter in inches Direction of rotation and tip configuration and minor aerodynamic characteristics Structural and operational features Basic diameter in feet Major aerodynamic characteristics 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 5. Left-Hand Models. The left-hand version of an approved propeller model is eligible at the same rating and diameter limitations as listed for the right-hand model. 3 P-870 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. (2) Fluid. Eligible with Hamilton Standard fluid deicing slinger ring assemblies only. (b) Propeller Spinner. Eligible with spinner supplied by Hamilton Standard. Add 26 1/2 lb. when spinner used.
