Confidence Rating: Accident investigation report completed and information captured
The commercial pilot/owner of the experimental, amateur-built airplane reported that, the day before the accident flight, the airplane experienced a vibration during flight. After landing, he attempted to determine the cause of the vibration without success. The next day, he conducted the accident flight to attempt to duplicate the vibration. Shortly after takeoff, one of the propeller blades separated. The pilot subsequently conducted a forced landing. The engine mounts were substantially damaged due to the unbalanced condition at the hub caused by the separated blade. The separated propeller blade was recovered, and postaccident examination of the propeller blade revealed that it had failed at the hub due to extensive fatigue cracking.
Probable Cause: The failure of a propeller blade at the hub due to fatigue cracking.
