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, just after takeoff from a remote off-airport landing site, the airplane’s left wing impacted a small sapling tree which resulted in a loss of directional control. The pilot attempted to correct for the loss of control to no avail. The airplane subsequently impacted a stand of trees sustaining substantial damage to the fuselage and both wings. The pilot reported no preaccident mechanical failures or malfunctions that would have precluded normal operation.
