NTSB narrative
The pilot stated that, after a 15-minute flight, he landed the airplane on a familiar, gravel runway at a slow groundspeed. Immediately thereafter, the airplane began to veer right, and the pilot used the brakes and aileron inputs in an effort to return to the runway center. Despite the pilot's attempts to regain directional control, the airplane continued off the right side of the runway, struck a ditch, and then came to rest inverted.
The pilot reported that the loss of directional control was precipitated by a landing gear malfunction and that a brake likely seized after touchdown. Although the brakes could not be operated with the pedals during postaccident examination of the braking system, it could not be determined whether this was a result of the accident and/or the subsequent recovery.
Probable cause
The loss of braking action during the landing roll on a gravel runway for reasons that could not be determined based on the available information.

- 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.
