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, after performing a normal three-point landing, he attempted to exit the runway onto a taxiway. The airplane was still travelling at high speed, and during the turn toward the taxiway, the airplane ground looped to the right. As a result, the left wing and horizontal stabilizer impacted the runway surface, resulting in substantial damage to both. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
