Aircraft involved
Probable cause & findings
The pilot's failure to maintain directional control during the landing roll with a tailwind.
Factual narrative
The pilot of the tailwheel-equipped airplane reported that, while practicing stop and go landings, the airplane touched down and immediately veered to the 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 airplane was landing runway 21R with the wind direction heading of 070 at 4 knots.
