Analysis

The pilot stated that during takeoff from an unimproved airstrip, in a tailwheel-equipped airplane, she encountered a gust of wind just as the tail lifted off the ground. The airplane veered left and impacted trees and came to rest amongst the vegetation. Both wings, horizontal stabilizer, and elevator sustained substantial damage. The pilot reported there were no preaccident mechanical malfunctions of failures with the airplane that would have precluded normal operation.
