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 pilot of the tailwheel-equipped airplane reported that, while practicing stop-and-go landings, the airplane touched down and immediately veered right. The pilot attempted to correct with opposite rudder; however, the airplane ground looped to the right and exited the right side of the runway. During the ground-loop, the left wing struck the ground. The airplane subsequently nosed over and came to rest inverted. The airplane sustained substantial damage to the left wing lift strut and wing. The pilot reported that there were no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation. At the time of the accident, the pilot was landing the airplane on runway 21R with wind from 070° at 4 knots.
