NTSB narrative
While performing a touch-and-go, the pilot stated that he was applying power for his go-around when the right wing started “dropping” and the airplane ground looped, coming to a stop facing west. The pilot commented that he looked straight ahead and saw his right main landing gear laying on the ground. The airplane sustained substantial damage to the main landing gear mounting plate, lower wing strut attach fitting, and surrounding structure. Postaccident inspection revealed that the right inboard mounting bolt and the right outboard forward landing gear strut attachment bracket bolt hold-down nut failed. Subsequently, the hold-down bracket bent, and the right main landing gear separated from the fuselage upon landing..
Probable cause
Failure of the right main landing gear attachment bolt and hold-down nut, resulting in the right main landing gear collapsing.

- 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, 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.
