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 was landing his tailwheel and tundra tire-equipped airplane on a remote off-airport landing site. While on short final approach and just before touchdown a gust of wind pushed the airplane to the left. The airplane touched down about five ft left of his intended touchdown point and the left main tire impacted a large hole. The airplane subsequently nosed over sustaining substantial damage to the right wing, right lift strut and rudder. The pilot reported no preaccident mechanical failures or malfunctions that would have precluded normal operations. In the recommendation section of the NTSB Accident/Incident Reporting Form 6120.1, the pilot stated that he knew the winds were erratic in the area, and the accident may have been prevented if he had selected another landing site where the winds were more predictable.
