Probable cause

The pilots failure to maintain aircraft control which resulted in overstress of the airplane. Contributing was VFR flight into IMC and thunderstorms.

Sequence of events

Analysis

The pilot was en route at 11,500 feet and was receiving traffic advisories from air traffic control, who advised him of heavy precipitation ahead. The pilot began a descent about 14 miles from his destination. ATC advised the pilot to maintain visual meteorological conditions, which he acknowledged. The pilot later reported he had encountered rain and turbulence and that he was not in VMC. ATC lost contact with the airplane soon afterwards. Witnesses reported a severe thunderstorm when they saw the airplane descend and crash. The investigation revealed the airplane had an inflight breakup; wreckage was strewn a distance of about two miles. The examination did not disclose evidence of mechanical malfunction.
