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 he was flying a tail-wheel equipped airplane and conducting his second landing at a back country airstrip. During the landing flare, the airplane floated longer than expected and was starting to drift to the left side of the runway. The pilot added full power to go around when the left main landing gear struck a bush and the airplane turned sideways. The right landing gear collapsed and the right wing was substantially damaged when it struck the ground. The pilot reported that after exiting the airplane he noticed that the wind was a gusting right quartering tailwind. The pilot reported no mechanical failures or malfunctions with the airframe or engine that would have precluded normal operations.
