## Summary

The FAA proposes to adopt 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 proposed AD would require removal of the affected propeller governors from service. This proposed AD results from three reports received of failed propeller governors. We are proposing 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.
