Incident Overview
During the landing attempt, the pilot overshot the centerline of the prepared runway and touched down on the grass adjacent to the runway. As the airplane rolled through the grass, it entered a ground loop. The ground loop resulted in the separation of the right main landing gear and the wing being dragged along the ground.
Pilot Report
The pilot reported that the rudder did not respond to his inputs intended to correct the overshoot. However, a subsequent inspection of the rudder control system revealed it was functional and operating correctly.
Post-Inspection Findings
Examination of the braking system showed that the brake pad was not excessively worn. The wheel brake line had been severed during the ground loop, but inspection found no evidence of pre-impact damage to the line. No other anomalies were identified in the landing gear or flight controls.
No Causal Determination
The investigation did not identify a specific component malfunction or pilot error as the cause of the event. The rudder system was found to be operational, and the brake components showed no pre-existing defects.
