Summary
The FAA proposes to adopt a new airworthiness directive (AD) for Hartzell Propeller, Inc., McCauley Propeller Systems, and Sensenich Propeller Manufacturing Company, Inc. propellers. This proposed AD would require maintenance actions amounting to an overhaul of the affected propellers. This proposed AD results from the investigation of a failed propeller blade and subsequent inspections of various propeller models returned to service by Southern California Propeller Service, of Inglewood, CA. We are proposing this AD to prevent blade failure that could result in separation of a propeller blade and loss of control of the airplane.
