Accident Sequence
The pilot reported attempting to take off from a remote gravel bar. During the takeoff roll, the airplane encountered a hump on the runway surface, which caused the airplane to veer to the left. Shortly after passing over the hump, the airplane became airborne.
As the airplane climbed, the left wing collided with trees and brush. The pilot was unable to maintain directional control following the collision. The airplane subsequently departed the left side of the gravel bar and came to rest in a stand of trees and brush.
Outcome
The airplane came to rest in a wooded area adjacent to the gravel bar. No further details about the condition of the aircraft or the pilot were provided in the source.
