NTSB narrative
During the landing roll, the airplane yawed to the right, and the pilot overcorrected to the left. He then applied right brake, and the airplane nosed over, coming to rest in an inverted position. The vertical stabilizer and rudder were substantially damaged. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot's failure to maintain airplane control during the landing roll and his excessive use of right brake, which resulted in a noseover.

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.
- API snapshot SHA-256: 8da1e0a2a26ee3ac3e9d77b5c3812a9da0902438945f9bab9d0ba26dbc6dd050; retrieved 2026-09-15T21:28:38.682Z.
