What happened
During the initial climb phase immediately following takeoff, the aircraft was observed to settle before beginning a slow climb. The aircraft then entered a right turn. When the air traffic controller queried the pilot regarding potential mechanical or operational problems, the pilot did not report any issues but indicated an intention to return and land. The controller subsequently issued a clearance to land on the nearest runway.
During this maneuver, the aircraft's wings were observed rocking. This was followed by the aircraft rolling into an inverted position to the right and descending into trees. At the time of the accident, the density altitude was 7,400 feet.
The investigation
An investigation into the accident revealed that the aircraft was 136 pounds over the maximum certified gross weight allowable.
