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 in a tailwheel-equipped airplane, the main landing gear wheels encountered an area of rough and uneven terrain, causing a bounce, and the airplane briefly became airborne again. After touching down again, the pilot applied heavy braking, and the airplane nosed over, resulting in substantial damage to the rudder and right wing lift strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
