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 in a tailwind, he lost directional control on the tail wheeled airplane, and it veered to the left. Subsequently, the main gear exited the runway surface and resulted in the airplane nosing over. The airplane sustained substantial damage to the vertical stabilizer and left-wing strut. The pilot reported that there were no preaccident mechanical failures or malfunctions that would have precluded normal operation.
