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, "I am 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 post-accident airplane examination performed by a Federal Aviation Administration Inspector revealed that no issues with the brake system was found.
