NTSB narrative
The pilot made an approach and landing to a 4,094 feet long by 80 feet wide, asphalt runway. During the landing roll, the pilot applied light braking to slow for an upcoming taxiway. While braking, the aircraft drifted left of the runway centerline. The pilot then applied right rudder and right brake which, the pilot believed to be ineffective. The aircraft veered off the runway and collided with a taxiway marker, resulting in the collapse of the left main gear and substantial damage to the fuselage. A post-accident examination of the braking system revealed no malfunction or failure.
Probable cause
The pilot's failure to maintain directional control during the landing roll. Factors include a taxiway marking sign located adjacent to the runway.

- 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.
