NTSB narrative
The pilot reported that, during landing on an uphill runway, the airplane touched down, veered slightly to the side, and then veered the other direction and back. Subsequently, the airplane exited the left side of the runway, the landing gear collapsed, and the stabilizer and elevator were substantially damaged. During postaccident examination, the left landing gear upper trunnion was found fracture separated. The investigation could not determine whether the upper trunnion fracture separation caused the airplane to veer from one direction to the other or whether the trunnion was fractured due to the landing gear collapsing.
Probable cause
A loss of directional control while landing, which resulted in a runway excursion and landing gear collapse for reasons that could not be determined.

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, cause areas. 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.
