NTSB narrative
During taxiing after landing to the west on a private, up-sloping grass field, the pilot added some power to make a 180 degree left turn to park the airplane. As he started the turn with left rudder and left toe brake, a strong wind gust caught the airplane, and the airplane nosed over. He said the winds were from the east at 10 knots with wind gusts to 18 knots. He said there was no mechanical malfunction with the airplane, and the accident could have been prevented, 'by cutting the engine after roll out and turning the aircraft around by hand.'
Probable cause
Failure of the pilot to maintain control of the airplane. A related factor was the wind gusts.

- 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. 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.
