Primary finding
Probable cause
The pilot's decision to takeoff from a rough airstrip in gusty wind conditions, which resulted in a loss of control.
Investigator assessment
Analysis narrative
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.
