Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The purpose of the instructional flight was to gain experience in flying the tail-wheel-configured airplane from the rear seat. Both pilots were flight instructors. The supervising instructor was in the front seat. The instructor looking to gain experience was in the rear seat. The pilots began by conducting two touch and goes on the turf runway without incident. However, as more aircraft entered the traffic pattern for the intersecting paved runway they decided to use that runway. The initial approach and flare to that runway, 13 (4,300 feet by 75 feet, asphalt), were stable. After touchdown the airplane drifted to the left. As the rear seat (flying) pilot attempted to correct, the airplane veered to the right, departing the right side of the runway and nosing over. The supervising instructor reported that there were no failures or malfunctions associated with airplane prior to the accident.

The supervising instructor reported that there were no failures or malfunctions associated with airplane prior to the accident. The supervising instructor reported having accumulated a total flight time of 1,497 hours, with 3 hours in the same make and model airplane.
