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 a wheel landing to the turf adjacent to an asphalt runway. Prior to the tailwheel contacting the ground, the pilot moved his toes to top the rudder pedals and inadvertently applied the brakes. The airplane then nosed over and came to rest inverted, which resulted in substantial damage to the left-wing strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
