What happened
Following touchdown on runway 36, the airplane experienced an immediate yaw to the left. The pilot reported that he was unable to maintain directional control of the aircraft during this phase of the landing roll. As a result, the airplane departed the paved surface from the left side of the runway.
The aircraft then ground looped, causing the right wing to collide with the ground. Despite the structural damage resulting from the impact, the pilot stated that he did not experience any mechanical problems with the airplane, flight controls, or engine assembly and accessories prior to or during the incident.
The investigation
Post-acc examination confirmed that the right wing sustained damage from the collision with the ground. The pilot's statement indicated no pre-existing mechanical issues with the airplane systems.
