NTSB narrative
The pilot reported that he made a normal landing on the runway. During rollout, he felt a vibration coming from the landing gear. When he exited the runway, the airplane turned abruptly to the left, as if the left brake had locked up. The uncommanded sharp left turn resulted in the airplane exiting the pavement and impacting a cement culvert. The examination of the runway revealed witness marks consistent with a locked left wheel brake. An examination of the airplane's left wheel assembly revealed that the tire rotated freely. No external evidence of brake failure was found. The reason for the intermittent anomaly associated with the brake assembly or cylinder was not determined.
Probable cause
The pilot's loss of directional control during landing resulting from binding of the left wheel's brake actuating system for an undetermined reason.

- 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.
