Default Dynon Servo Pulley Service Bulletin

Has anyone researched this Servo Pulley Bulletin? I don't think that it is applicable to our auto pilot system............Tom

I researched it, and spent more time doing so than was necessary because I began by looking in the wrong places. My RV-12 is an ELSA which means that my plane’s servos were purchased directly from Van’s. The plane’s Avionics Log shows that it is equipped with two Dynon SV-32 autopilot servos. The Dynon Service Bulletin lists SV-32 servos among those that are “not” affected.

They are not on any SLSA, or part of any RV-12 avionics kit that was sold by Van's
