Production basis Production Certificate No. 10 NOTE 1. Hub Model Designation Hub model designation HC - 1 3 X 20 - 8 D Denotes minor change not affecting eligibility L denotes left-hand rotation Denotes specific design features SAE No. 20 spline Hartzell blade shank size Number of blades Identifies basic design Hartzell controllable P-888 2 NOTE 2. Blade Model Designation Blade model designation L 84 33 H - 3 Number of inches cut off from basic diameter H when used indicates Hard Alloy. D when used indicates dimensional modification from original design Basic model or template Basic diameter in inches L when used denotes left-hand blade Diameter limits shown are nominal diameters of the assembled propeller and do not include the +1/4 inch to -1/8 inch manufacturing tolerance permissible. NOTE 3. Pitch Control. Eligible with Hartzell manual or constant speed control. Constant speed control includes the Hartzell governor Model A-1-1. Additional weight of governor is 4.5 lb. (NOTE: Some installations require a T-drive adapter for the governor. Additional weight of the Hartzell Model C-253-2 adapter is 2.7 lb.). NOTE 4. (a) Feathering. Not applicable. (b) Reversing. The -5 model incorporates a reversing feature. NOTE 5. Left-Hand Models. The left-hand version of an approved model propeller is eligible at the same rating and diameter as listed for the right-hand model. (See NOTES 1 and 2.) NOTE 6. Interchangeability. (a) 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. Group (a) 8433, 8433H*, 8433A *Hard alloy blades interchangeable only on seaplanes and amphibious aircraft. (b) Propellers. Only propellers listed in this data sheet may be replaced by corresponding propellers listed in Type Certificate Data Sheet No. P1EA provided the propeller model designations are the same except that the identifying basic digit "1" (see NOTE 1) is replaced by the letter "D". NOTES 7 and 8. Not applicable. NOTE 9. 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. Max. Dia. Min. Dia.
