NTSB narrative
The non-certificated pilot reported that after touchdown, he "...locked up the right wheel brake..." in an effort to avoid a fence and vehicles located at the end of the runway. Shortly thereafter, the airplane slid to the right and collided with the fence. A witness to the accident reported that the airplane touched down approximately two-thirds of the way along the 2,650-foot turf runway. After touchdown, during the landing rollout, the airplane collided with the fence that crossed (perpendicular) the departure end of the runway. The pilot stated that at the time of the accident the landing surface was wet.
Probable cause
The pilot's improper touchdown point. Factors include a wet landing surface.

- 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.
