Date of application for Type Certificate December 31, 1941. Production basis Production Certificate No. 14 NOTE 1. Hub Model Designation Minor change not affecting eligibility SAE propeller shaft size Blade shank size Number of blades Major model type 3 3 E 60 - 101 NOTE 2. Blade Model Designation Nominal reduction from basic diameter in inches Aerodynamic and structural features If used, indicates shank fairing design A 6801 C 18- T If used, indicates telescoped; "S", square cutoff Operational features (may indicate particular deicing assembly), does not affect eligibility 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 Model 6899. Page 3 P-786 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 propellers with basic diameter less than 14 feet or ± 1/4 inch permissible for propellers with basic diameter 14 feet or larger. NOTE 3. Pitch Control. Eligible with Hamilton Standard constant speed governor only. NOTE 4. Feathering. Eligible with full feathering control 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. NOTE 6. Interchangeable Blades. Blades with an "S" or "T" suffix (see NOTE 2) are not interchangeable aerodynamically or vibrationwise with each other or with blades having normal round cutoffs. Only blades listed in the same group of the following groups are areodynamically similar. Only blades listed under the same type in any one group are structurally similar. A higher type number implies a higher strength. This is due to differences in alloys and in cold working of the blade surface. Type 1 includes standard alloy non-surface treated blades; Type 2, hard alloy non-surface treated blades; Type 3, hard alloy blades with cold worked shanks; Type 4, hard alloy blades with cold worked shanks and shot peened surfaces. The following defines the degree to which these blades may be used interchangeably in the same diameter without a flight performance test and without a vibration survey: Type 2 blades may replace Type 1 blades in the same group, but not vice-versa. Type 3 blades may replace either Type 1 or Type 2 blades in the same group, but not vice-versa. Type 4 blades may replace either Type 1, Type 2, or Type 3 blades in the same group, but not vice-versa. Reference should always be made to the ratings of the blades, and blades with different model numbers cannot be incorporated in the same propeller unless the aircraft specification specifically permits this.
