Probable cause

The spatial disorientation experienced by the pilot in IMC, his failure to maintain aircraft control, and the exceeding of the design stress limits of the aircraft. Factor(s) in this accident were: the pilot's inadequate preflight planning, the VFR flight into IMC, his poor judgement, his overconfidence in his personal ability, and his lack of experience in instrument flying.

Analysis

The non-instrument rated pilot was informed that the weather at his destination airport was IFR, however he elected to commence the flight under a VFR flight plan. While flying between cloud layers en route, the weather deteriorated, and he entered IMC. While being vectored toward better weather conditions, he became disoriented, and entered a high speed dive. During the recovery from the dive, approximately 50 percent of the stabilator separated from the airplane. The pilot was able to fly the airplane to a nearby private airport. He landed the airplane hard on the grass adjacent to the runway. An inspection of the stabilator surfaces revealed a positive 'g' overload failure; there was no evidence of metal fatigue.
