NTSB narrative
The certificated private pilot was attempting a southeasterly departure from an 800 feet long sand bar. He stated that the takeoff run required a correction for a strong left crosswind. During the takeoff run, as the airplane became airborne, a strong gust of wind pushed the airplane to the right, and over an area of soft snow. He said that when the wind decreased, the airplane's main wheels contacted the soft snow, and the airplane nosed over. The airplane sustained substantial damage to the wings and fuselage. The pilot reported wind conditions at the time of the accident to be from the east at 20 knots, with peak gusts to 40 knots.
Probable cause
The pilot's intentional flight into known adverse weather. Factors associated with the accident were the variable crosswind conditions, and the pilot's inadequate compensation for those wind conditions.

- 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.
