What happened
During a flight instruction session, a student pilot was operating a tailwheel-equipped airplane. After landing on a dry, paved runway, the pilot needed to correct for a left crosswind. During the rollout, the student pilot allowed the aircraft to veer to the left of the runway centerline.
The flight instructor attempted to take control of the aircraft to realign it with the runway centerline. However, the aircraft entered a ground loop to the left. This maneuver caused the right main landing gear to collapse, which subsequently led to the right wing striking the runway surface.
The investigation
An examination of the aircraft revealed that the right wing sustained structural damage due to the impact with the runway. Prior to the accident, the pilot noted that there were no mechanical anomalies present in the aircraft.
