Analysis

The pvt rated pilot did not hold a multiengine or instrument rating. The pilot and passenger were returning from vacation. A witness near the accident site stated that she saw the aircraft descend out of a low over last at a very steep nose down angle. The aircraft began to climb but then pitched down and spun to the gnd. Examination of the aircraft wreckage revealed that left and right horizontal stabilizer, the elevators and the rudder had seperated in-flight. Examination of the failed components revealed evidence that was indicative of overstress due to aerodynamic overload.
