NTSB narrative
The pilot was landing on a remote off-airport site in a tailwheel-equipped airplane. He stated that the landing area was on a 15-degree slope. The landing was uneventful, but shortly after stopping the airplane, a gust of wind turned the airplane so the nose was pointing down the hill. The airplane began rolling down the slope, and then nosed over. The airplane sustained substantial damage to the vertical stabilizer, rudder, and wing. The pilot reported that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation.
Probable cause
The pilot's selection of unsuitable terrain for takeoff/landing and failure to maintain control of the aircraft.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
