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

During the takeoff roll from a grass area adjacent the paved runway surface, the airplane’s left main landing gear wheel struck a “muddy pothole.” The airplane’s nose then veered down and to the left and the pilot lost directional control of the airplane. The airplane subsequently struck a fence, and the right wing impacted a tree substantially damaging it. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
