## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for Pratt & Whitney Canada (PWC) PT6A-60A and PT6A-65B turboprop engines. This proposed AD would require replacing Woodward propeller governor assemblies, part number (P/N) 8210-212H. This proposed AD is prompted by six incidents during airplane acceptance flight testing where directional control of the airplane was difficult to maintain during landing. The actions specified in this proposed AD are intended to prevent loss of directional control and damage to the airplane.
