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 while transitioning from the landing roll, to taxi, on a gravel road with a 12- to 15-knot tailwind, a gust of wind lifted the tail. The airplane rotated and the left wing collided with a fence. The left wing and its associated lift strut were substantially damaged. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation.
