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 reported that, during short final, just before he initiated a landing flare, he lost sight of the dirt airstrip and initiated a go around. Shortly after, the pilot turned right, but he quickly realized that he would not be able to outclimb several treetops, so he lowered the nose attitude. Subsequently, the right wing struck a tree, the airplane impacted the ground at a steep angle and came to rest inverted. The airplane's wings and fuselage were substantially damaged. The pilot reported that there were no preimpact mechanical failures or malfunctions with the airplane or engine that would have precluded normal operation.
