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 departing from a road in the weight-shift control aircraft. At takeoff, the aircraft “pulled to the left” and struck a tree off the paved surface as the pilot aborted the takeoff. Afterwards, the pilot stated there were no mechanical deficiencies with the aircraft that would have precluded normal operations, and that the pull was likely due to an improperly adjusted wingtip.
