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 a tailwheel-equipped airplane reported that the airplane touched down on the runway without incident. Shortly after touchdown, the airplane encountered a sudden wind gust and turned to the left. The pilot attempted to correct with aileron and rudder input. However, the airplane continued to turn left about 180° and came to rest upright. He stated that his aileron input was incorrect and exaggerated the left turn. In addition, he reported he was an inexperienced tailwheel pilot and the accident was "100% a case of pilot error." The airplane sustained substantial damage to the right wing and aileron. The pilot reported no preaccident mechanical failures or malfunctions that would have precluded normal operation.
