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, during the landing, the airplane suddenly veered left, ground looped, exited the runway, and nosed over. Examination revealed that the airplane had a blown right tire and that it had sustained substantial damage to the vertical stabilizer and right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. A review of photographs of the tire damage provided by a Federal Aviation Administration inspector revealed that the damage was consistent with sideloading of the right main landing gear during the ground loop to the left.
