NTSB narrative
The pilot reported that upon landing, the airplane veered as if the left brake was locked and the airplane exited the runway, incurring substantial damage to the left wing. The pilot also reported that after the accident, when the left brake caliper assembly was disassembled, a metal shaving was found in the bleed valve port. The non-ferrous metal shaving appeared to be the remnant of drilling operations as evidenced by its spiral shape. There was no flattening of the spiral shape that would indicate that the shaving had become jammed between the caliper piston and its bore. Examination of the brake caliper revealed no malfunctions or failures that would have precluded normal operation. Based on the lack of available evidence that the brake had become locked, it is likely that the loss of directional control was for non-mechanical reasons.
Probable cause
The pilot’s failure to maintain directional control during landing.

Source notes (4)
- 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.
