Probable cause
The failure of the two fuel control unit drive bearings for reasons that could not be determined based on the available evidence, which resulted in an uncommanded engine acceleration and subsequent overspeed condition. Contributing to the accident was the pilot’s improper autorotation, which resulted in a hard landing.
