Airworthiness Directives; Ontic Engineering and Manufacturing, Inc. Propeller Governors, Part Numbers C210776, T210761, D210760, and J210761
The FAA is adopting a new airworthiness directive (AD) for certain serial numbers (S/Ns) of Ontic Engineering and Manufacturing, Inc. propeller governors, part numbers (P/Ns) C210776, T210761, D210760, and J210761. This AD requires removal of the affected propeller governors from service. This AD results from three reports received of failed propeller governors. We are issuing this AD to prevent loss of propeller pitch control, damage to the propeller governor, and internal damage to the engine, which could prevent continued safe flight or safe landing.
