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, while landing, when the tailwheel touched down, the airplane began to veer left. The pilot attempted to correct the veer and applied brakes; however, the airplane 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.
