NTSB narrative
The airplane sustained substantial damage on impact with terrain and an object following a gear collapse during landing roll. The pilot was uninjured. A mechanic stated, "When lifted the Right wing the gear fell down and locked. I jacked the left wing to engage the lock, the left gear was down but, was not locked. The nose gear would not fall down due to the gear doors were bent, so I used the hydraulic pump to push it down and it locked." FAA inspectors found that the airplane landed long and touched down on the left side of the centerline. An inspector stated, "Photographs indicate that the aircraft immediately began a hard right turn. Shortly before exiting the runway, skid marks show that the right main landing gear started to fold up. The aircraft came to rest on the east side of the runway with the nose and right main gear retracted. One runway light was broken off after it was struck with the left wing. The pilot reported, "As I turned from base to final, I again ordered a pre-landing checklist noting that the gear was showing 3 green lights on the panel. The initial phase of the landing and touch down seemed normal but after a short period (I cannot define how need) as the aircraft proceeded down the centerline, I noticed the right side of the aircraft descending as though the right gear was collapsing and the right wing descending toward the pavement."
Probable cause
The gear collapse for undetermined reasons during the landing roll. A factor was the pilot not using a proper touchdown point by landing long.

- 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.
