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 of the tailwheel-equipped airplane was performing the last approach after a series of touch-and-go takeoffs and landings. The airplane bounced after the main wheels touched the runway, and veered to the left. The pilot applied rudder and aileron control inputs; however, the airplane continued to pull to the left. As the airplane approached the runway edge, the pilot applied the brakes, but the airplane departed the runway and nosed over. The airplane sustained substantial damage to both wings and the aft fuselage structure during the accident sequence. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. She further stated that the accident could have been avoided if she had reacted to the divergence sooner and applied full aft elevator control during the roll.

Factual narrative

The private pilot of the tailwheel equipped airplane was performing the last approach after a series of touch-and-go landings. The airplane bounced after the main wheels touched the runway, and the airplane veered to the left. The pilot applied rudder and aileron control inputs, however, the airplane continued to pull to the left. As the airplane approached the runway edge, she applied the brakes, and the airplane subsequently departed the runway and nosed over. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation. She further stated that the accident could have been avoided if she reacted to the divergence sooner, and applied full aft elevator control during the roll. Winds at the time of the accident were calm. The airplane sustained substantial damage to both wings and the aft fuselage structure during the accident sequence.
