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 a planned full-stop landing, the airplane bounced back into the air after the initial touchdown and then settled to the runway a second time. Almost immediately after the second touchdown the airplane veered sharply to the left and departed the runway surface. Before the pilot could get the airplane to come to a stop its left wing struck a tree, resulting in the airplane spinning. The pilot said that the airplane had no mechanical or directional control anomalies, and that he should have executed a go-around when the airplane first bounced back into the air.
