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 departing from a remote off-airport site in a tailwheel-equipped airplane. The pilot reported that just after takeoff, as the airplane remained in ground effect, a crosswind pushed the airplane over the edge of a hill where the wind direction changed, and it subsequently settled back to the ground and collided with terrain. The airplane sustained substantial damage to the left and right wings, horizontal stabilizer. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
