Event Description
According to the pilot's account, during the landing roll, the airplane began to drift to the right. The pilot applied left rudder and brakes, but these inputs did not correct the rightward drift. Subsequently, the airplane suddenly banked to the right, departed the runway, and collided with trees.
Damage and Examination
Post-accident examination of the airplane revealed that the right main landing gear had collapsed. The horizontal stabilizer, empennage, wings, ailerons, and lower fuselage sustained damage. Further inspection identified a faulty down-lock switch in the right main landing gear.
Additional Findings
The examination also noted that the right main landing gear's down-lock switch was faulty. No other mechanical anomalies were reported in the source.
