Production basis Production Certificate No. 14 NOTE 1. Hub Model Designation 4 3 E 60 - 300 See * below. SAE propeller shaft size Blade shank size Number of blades Major model type *A dash number of 300 or lower added to the propeller model designation indicates the suitable type of pitch control (see Note 3) and minor changes which do not affect eligibility. Dash numbers of 301 or above include the complete blade assembly and all of the rotating deicing system components, as well as indicating the suitable type of pitch control (see Note 3) and minor changes. NOTE 2. Blade Model Designation A 6895 C - 8 T (If used) indicates telescoped; "S", square cutoff Nominal reduction from basic diameter in inches. Operational features (may indicate particular deicing assembly), does not affect eligibility. Aerodynamic and structural features (If used) indicates shank fairing design. The blade model designation suffixed with "T" indicates a diameter reduction by telescoping. Blade models with square cutoffs in accordance with Hamilton Standard blade drawings are suffixed with "S" except the following blades use square cutoffs not designated by "S": Blade models 6895 6869 (-0 to -4 have round cutoffs, all other diameters are square) 6901 6903 Telescoped blades and blades with a square cutoff are eligible at the same ratings and diameter limits as blades with standard cutoff. Diameter limits shown are nominal diameters of the assembled propeller and do not include the ± 1/8 inch manufacturing tolerance permissible for prpellers with basic diameter less than 14 feet or ± 1/4 inch permissible for propellers with basic diameter 14 feet or larger. *Blade model 6969 is nickel plated. NOTE 3. Pitch Control. Eligible with either Hamilton Standard engine oil control assembly or integral oil control assembly as follows: (a) Hubs having dash numbers of 200 or lower, or 301 through 600 must be used only with engine oil control assemblies. (b) Hubs having dash numbers of 201 through 300, or 601 or higher must be used only with integral oil control assemblies (approximately 65 pounds additional weight). NOTE 4. (a) Feathering. Eligible with full feathering control installed in accordance with the propeller manufacturer's instructions. (b) Reversing. Eligible with reversing controls installed in accordance with the propeller manufacturer's instructions. NOTE 5. Left Hand Models. The left-hand version of an approved model propeller is eligible at the same rating and diameter limitations as listed for the right-hand model. 3 P-871 NOTE 6. Interchangeable Blades. Blades with an "S" or "T" suffix (see Note 2) are not interchangeable with each other or with blades having normal round cutoffs. Only blades listed in the same group in (a) or (b) are interchangeable in the same diameter without a flight test. (a) Interchangeable aerodynamically and vibrationwise; Group (1) 6869 and 6901 (b) Interchangeable aerodynamically only; Group (1) 6895 and 6969 *(nickel plated version of 6895) NOTE 7. Accessories.
