NTSB narrative
During the landing roll, the right landing gear steel fitting welds broke, and the axle, brake, wheel, and wheel fairing separated from the airplane. The right landing gear strut dug into the sod and the airplane cartwheeled, coming to rest inverted in the center of the runway. The left wing separated from the airplane, and the vertical and horizontal stabilizers were crushed. No other anomalies were found that would have precluded normal operation of the airplane.
Probable cause
Failure of the steel weld fittings on the right main landing gear.

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. 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.
