336 autopilot
 

i am a new owner of a 336 (N3875U) am looking for a form 337 to install a s-tec autpilot or equivalent

I would think that S-Tec would be the best source for that data, unless they have not certified one of their autopilots in a 336. If they have not, whew, a field approval for that would seem to me to be very difficult if not impossible to obtain.

Wish I had a better answer. Maybe someone else will.
