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 that, during the landing roll as the tailwheel was almost in contact with the ground, the airplane started to veer to the right. He attempted to correct to the left but lost directional control, and the airplane ground looped to the left. The airplane sustained substantial damage to its right wing and firewall. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation system on the airport reported that, about the time of the accident, the wind was from 340° at 10 knots, gusting to 17 knots. The pilot landed on runway 23.
