NTSB narrative
The certificated private pilot reported that while on approach for landing on runway 22, he encountered a strong right crosswind. After touchdown, during the landing roll, a gust of wind lifted the right wing, and the airplane veered to the left. The airplane ultimately departed the left side of the runway, rolled down an embankment, and came to rest in an area that contained trees. The airplane sustained substantial damage to the right wing and right horizontal stabilizer. The pilot reported that there were no preaccident anomalies with the airplane.
Probable cause
The pilot's inadequate compensation for wind conditions during the landing roll, which resulted in an inadvertent ground loop/swerve. A factor associated with the accident was a crosswind.

- 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.
