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 takeoff the airplane began to drift to the left immediately after rotation. The pilot further reported that he applied right aileron, but the drift continued and the airplane's left main landing gear struck a tree within a tree line about 100 feet to the left of the runway. After the impact, the airplane sank further into the trees and came to rest slightly nose high and left wing down. The fuselage, both wings, and horizontal stabilizer were substantially damaged. The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation.
