Probable cause

The pilot's inability to maintain aircraft control and foreign object damage to the aileron and wing. The restricted movement of the flight controls was a factor.

Analysis

The pilot was conducting a predator (coyote) control flight over private rangeland. During the flight, at a reported altitude of approximately 40 feet above ground level (AGL), the passenger inadvertently discharged a semiautomatic 12-gauge shotgun. The pilot, who was seated in the forward seat, reported that the gun fired 3-4 times, striking the right wing, fuel tank and aileron assembly. He reported that the damage resulted in a loss of aileron and elevator control. The airplane entered a descending turn to the right and subsequently impacted terrain in a nose-low attitude. The pilot reported the aircraft was on fire upon touchdown and continued to burn after the impact. The pilot reported that there were no preexisting mechanical malfunctions or failures that contributed to the accident.
