Unsafe condition
This AD was prompted by a report of an oil spray nozzle and certain screws that were not installed on the propeller gearbox. The FAA is issuing this AD to detect and address the oil spray nozzle and screws that were not installed on the propeller gearbox. The unsafe condition, if not addressed, could result in an in-flight loss of engine oil, engine in-flight shutdown, and loss of control of the airplane.
Affected ADs
None.
