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 landing in a tailwheel-equipped airplane, the airplane bounced and settled back onto the runway in a two-point landing configuration. Subsequently, the airplane suddenly veered to the right. Despite the pilot's control inputs, the airplane ground looped and exited the right side of the runway. Examination of the airplane revealed that the left wing sustained substantial damage. The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
