Probable cause
The pilot-in-command's failure to select suitable terrain for landing. 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
During the landing roll on a rough and uneven gravel bar, the airplane's right main landing axle failed. The airplane traveled approximately 150 feet before ground looping. Examination of the broken axle revealed no mechanical malfunction or failure.
