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 airplane impacted the runway surface during takeoff after it prematurely lifted off and cartwheeled to a stop facing in the opposite direction. The pilot stated that he knew the airplane was not at flying speed when it lifted off, so he moved the control stick forward to return the airplane to the runway surface, but the airplane bounced and veered left. He added additional engine power in attempt to keep the airplane flying. The left wing then dropped and contacted the runway, cartwheeling the airplane. The pilot reported that there was no mechanical malfunction/failure of the airplane at the time of the accident.
