Weight of additional furnished equipment: Weight, lb. (a) Ignition coils (4) 4.1 (b) Selenium rectifier .65 (c) Voltage regulator .7 NOTE 4. The Model H-63C engine has been approved specifically for helicopter applications and the Model H-63CP engine has been approved specifically for fixed-wing applications. NOTE 5 The crankshaft of the Model H-63CP engine has not been substantiated at stress levels higher than those encountered with a fixed pitch propeller resulting in a full throttle static r.p.m. of 4000 r.p.m. or more. Accordingly, this engine is not eligible for use with any controllable propellers or with any fixed pitch propellers resulting in a full throttle static r.p.m. of less than 4000 r.p.m. Before this engine can be eligible for use with such propellers, the crankshaft must be substantiated endurance wise at at least the maximum stress levels which will be encountered with the particular propeller in question. ...END... ``` ## ADs None name its models. ## STCs approved under this data sheet (1) - [STC SE04651CH](https://openairdocs.org/stc/SE04651CH): To allow use of l00R grade aviation fuel meeting Swift Fuel, LLC specification SPEC-l00R-22.
