NTSB narrative
The pilot of the tailwheel-equipped airplane reported that as she applied throttle for takeoff the nose veered to the right, she corrected with left rudder pedal. However, the airplane continued to veer to the right, the pilot added more throttle which worsened the right turn. Subsequently the pilot closed the throttle and applied left brake, the airplane turned to the left, ground looped and exited the runway. The airplane came to rest in a ditch adjacent to the runway, the two occupants were able to egress from the airplane without further incident. The airplane sustained substantial damage to the right wing and tail section. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot’s failure to maintain direction control during takeoff roll which resulted in a ground loop, and subsequent runway excursion.

- 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: local date, investigation status, coordinates, cause areas. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2025-07-12.
