Richard Another interesting note. While the type certificate of the engine includes all those generators (certifying that the engine can legally and mechanically drive them all), the type certificate of the 415-C only includes the 13 amp, and the type certificate of the 415-D and heavier gross coupes includes the 13, the 20 and the 35 amp generators. Since the type certificate of the plane is more restrictive, it overrides the list of generators on the engine's type certificate. Therefore you need a 337 to install the 20 or 35 amp generators in a 415C, even when they are listed in the engine's TC. That would make sense if the wiring on the 415-C was of a lighter gage than in the 415-D and higher gross coupes, which is not the case. I have been dealing with the FSDO and my IA to install a 20 amp in my 415-C. I had to document all of the above and I am ready to prepare the 337.
