Piper PA-18-150 N4231Z accident near Hunter Creek, Alaska

Probable cause

The pilot’s loss of directional control during takeoff roll in gusting wind conditions.

NTSB analysis

The pilot reported that during the takeoff roll from a remote gravel bar in a tundra tire-equipped airplane, a gusting crosswind banked the airplane to the right, and it subsequently came to rest inverted and sustained substantial damage to the wings and empennage. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. At the time of takeoff, the pilot reported the winds to be gusting about 45 to 50 knots, which he said exceeded rudder and aileron authority.
