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, while landing he elected to change from a three-point landing to a two-point landing. Upon touch down, the airplane veered left and departed the runway surface. The pilot elected to go around and "applied full right rudder and power." Concerned the airplane would not gain enough altitude to clear the obstacles, the pilot reduced engine power and landed off the runway surface. Subsequently, the airplane impacted vegetation and the left main landing gear collapsed. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preimpact mechanical failures or malfunctions with the airplane or engine that would have precluded normal operation.
