Witness Account
A witness near the accident site provided an account of the aircraft's final maneuvers. According to her statement, the aircraft descended out of a low overcast at a very steep nose-down angle. The aircraft then began to climb, but shortly thereafter it pitched down and entered a spin, subsequently impacting the ground.
Wreckage Examination
Investigators examined the aircraft wreckage and found that the left and right horizontal stabilizers, the elevators, and the rudder had separated from the aircraft while it was in flight. Further examination of these separated components revealed evidence that was indicative of overstress due to aerodynamic overload.
Pilot and Flight Information
The pilot held a private pilot certificate but did not hold a multiengine rating or an instrument rating. At the time of the accident, the pilot and a passenger were returning from vacation.
