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 he planned to depart from a short grass field. To obtain more clearance from the trees at the end of the 700-foot strip, the pilot planned to turn just after takeoff. The pilot added that there was about a 10- to 20-degree right crosswind. During the takeoff, the airplane turned into the wind and the pilot was unable to correct that turn. The pilot attempted to climb through a small gap in the tree line; however, the airplane’s right wing collided with a tree and the airplane subsequently impacted the ground. Postaccident examination of the airplane revealed that the right wing and fuselage sustained substantial damage. The pilot reported no preimpact mechanical malfunctions or anomalies that would have precluded normal operation.
