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 reported he had landed at his destination airport in his tailwheel-equipped airplane and was turning off the runway onto the taxiway when the airplane’s right wing dipped and struck the runway. The airplane subsequently ground looped, nosed over and came to rest inverted. The airplane sustained substantial damage to both wings and left horizontal stabilizer. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot also reported that the degree and speed of the turn resulted in the wing striking the runway.
