Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, during the landing roll, the airplane encountered a wind gust. He applied right rudder to counter the gust; however, his foot slipped off the right rudder pedal. To prevent a runway excursion to the left, the pilot attempted to use only the right heel brake to realign the airplane's heading; however, he inadvertently depressed both the left and right heel brakes, and the airplane nosed over. The airplane sustained substantial damage to the vertical stabilizer and the rudder. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Factual narrative

The pilot in the tailwheel-equipped airplane reported that during the landing roll, the airplane encountered a wind gust. He applied right rudder to counter the gust, however, his foot slipped "completely off" the right rudder pedal. A runway excursion to the left was imminent, and the pilot attempted to use only the right heel brake to realign the airplane's heading. However, he inadvertently depressed both the left and right heel brakes, and the airplane nosed over. The airplane sustained substantial damage to the vertical stabilizer and the rudder. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
