Probable cause
failure of the pilot to maintain directional control of the airplane during the takeoff roll, which resulted in a ground swerve. The location of the tree was a related factor.
Sequence of events

Analysis
As the pilot was attempting to takeoff, the airplane exited the runway to the left and impacted a tree. The pilot stated that he lost control of the airplane during the initial takeoff roll. An examination of the airplane failed to reveal any preexisting mechanical anomaly.
