Primary finding
Probable cause
The pilot’s failure to maintain directional control of the airplane during the landing roll, which resulted in a ground loop and impact with terrain.
Investigator assessment
Analysis narrative
The pilot reported that, during the landing roll on a remote gravel bar, the airplane veered to the right. He applied left rudder but was unable to correct and the airplane ground looped to the right, resulting in substantial damage to the left wing, left aileron and elevator. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
