Analysis
The pilot was doing aerobatic maneuvers in the Cessna 172 airplane with three passengers and a heavy load of fuel aboard. The maneuvers consisted of buzzing boats on the lake at very low altitude, at least one complete aileron roll, several very abrupt pull-ups, several very abrupt level-offs at very low altitude, and several hammerhead type turns. The last maneuver, which terminated with the accident, was a steep pullup and climb followed by a hammerhead turn and a delayed pullout at the bottom which resulted in impact with the terrain. The aircraft was operating in the utility catagory of airworthiness on the accident flight. For this catagory, at the time of the accident the aircraft was 323 pounds over it's maximum allowable gross weight and 3.1 inches beyond it's allowable aft c.g. limit.
