NTSB narrative
The airplane was landing on runway 25, and the wind was out of the north at 10 knots. The pilot said that immediately after touch down, the wind gusted from 20 to 30 knots. He reported that his right wing was lifted up and the airplane veered off the left side of the runway. The pilot said that the left wing impacted a sign and the airplane nosed over. He reported that the vertical stabilizer was bent, the left wing had several ribs bent, and the canopy was broken.
Probable cause
The student pilot's failure to maintain aircraft control during landing roll. A contributing factor was the gusty cross-wind weather condition.

- 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.
