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

According to the pilot, during taxi on a loose dirt surface, he initiated a left 180° turn. He reported that he was using a "fairly aggressive power setting to compensate for the surface conditions." During the left turn, the right wingtip struck the ground. Additionally, the propeller struck the ground, and the airplane then rolled left, and the left wing struck the ground. The airplane sustained substantial damage to left wing. The pilot reported that the accident could have been prevented if the airplane's power setting had not been more than what was needed and that "a more conservative power setting and slower taxi speed could prevent future occurrences." The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
