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 was making a full-stop landing when the airplane began to veer to the right. He said that this wasn't unusual for the airplane and he attempted to correct the excursion with additional power to “prop wash” the airplane back to the left. The action failed. The pilot then decided to add full power and take off. The pilot was never able to completely regain control of the airplane and it collided with a tree off the left side of the runway. The left wing, left main landing gear, and the propeller showed substantial damage. A postaccident examination revealed no prexisitng mechanical anomalies.
