NTSB narrative
According to the pilot in the tailwheel-equipped airplane, he had performed two previous touch-and-go takeoffs and landings. During the third landing roll, the tailwheel settled on the runway, and then the airplane nosed over. He reported that he was “not certain whether I accidentally stepped on the brakes or the brakes seized."
The airplane sustained substantial damage to the vertical stabilizer and the rudder.
A Federal Aviation Administration inspector’s postaccident examination of the brake system revealed no preimpact mechanical malfunctions or failures that would have precluded normal operation.
Probable cause
The pilot's improper brake application during the landing roll, which resulted in a nose-over.

- 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.
