NTSB narrative
After an uneventful touchdown, the tailwheel-equipped aircraft began veering to the right during the landing roll. Although the pilot applied full left rudder, the aircraft did not respond. The pilot therefore applied partial left braking along with the full left rudder deflection. Although this caused the aircraft to begin tracking straight, the tail lifted off the ground and it began to nose over. When it started to nose over, the pilot released the brake application, but the aircraft continued over onto its back. It was later determined that the right brake was dragging/binding during the landing roll, and the amount of left brake necessary to keep the aircraft tracking straight resulted in the aircraft nosing over.
Probable cause
The binding/grabbing of the right main gear braking system during the landing roll.

- 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.
