Probable cause
The pilot's failure to maintain directional control of the airplane on landing roll out in unsuitable terrain. Contributing to the accident was the rough and uneven terrain.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
After touchdown on a mountain top, the pilot lost directional control of the airplane. The airplane then nosed over on its back. The landing area was rough and uneven.
