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

During the landing flare, the pilot misjudged his height above the runway, resulting in a higher-than-normal flare and a harder-than-normal touchdown. Immediately after the airplane made contact with the runway, it began to veer from side to side, and the pilot was unable to maintain directional control. According to the pilot, there were no issues with the rudder or the tailwheel steering systems, but he did feel that the glare from bright sun that he was landing toward had contributed to his abnormal flare height.
