NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The flight instructor was providing flight instruction to the student pilot in a tailwheel-equipped airplane. The flight instructor said that just after landing on a dry, paved runway, which required a correction for a left crosswind, the student pilot allowed the airplane to veer to the left of the runway centerline. The instructor said that he took control of the airplane in an attempt to realign the airplane, but the airplane ground looped to the left, and the airplane's right main landing gear collapsed. The airplane's right wing struck the surface of the runway, and sustained structural damage. The first pilot noted that there were no preaccident mechanical anomalies with the airplane.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The instructor pilot's inadequate supervision, and the dual student's failure to maintain directional control. Factors associated with the accident were a crosswind, and an inadvertent ground loop.
