Aircraft involved
Probable cause & findings
The pilot's incorrect brake application during taxi, which resulted in a nose over.
Factual narrative
The pilot of a tailwheel equipped airplane reported that during the taxi after landing, he "applied the brakes to slow down further" and suddenly the airplane nosed over. He further reported that he recently replaced the 29 inch Alaska Bushwheels with smaller 6.00x6 tires. According to the pilot, this made the Cleveland double puck brakes "very sensitive." A postaccident examination revealed substantial damage to the right wing and vertical stabilizer. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
