NTSB narrative
During a cross-country flight the pilot said he listened to the automated weather report a few miles west of his destination and noted crosswinds at 17 knots, gusting to 20 knots. The pilot continued the approach to landing and reported the touchdown was "uneventful," but during the landing roll a gust of wind rotated the nose 90 degrees into the crosswind. Subsequently, the airplane departed the runway surface and impacted a ditch adjacent to the runway, causing the nose wheel to collapse. The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Examination of the airplane revealed substantial damage to the engine firewall.
Probable cause
The pilot's failure to maintain directional control during landing. Contributing to the accident was the pilot's inadequate compensation for the crosswind during landing.

- 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.
