The private pilot, who was the sole occupant of the aircraft, received minor injuries, and the aircraft sustained substantial damage. The personal pleasure flight, which was departing for Rock Springs, Wyoming, was being operated in visual meteorological conditions at the time of the accident.

This was followed by the aircraft impacting a tree situated just beyond the departure end of the field.
