Communications
The pilot, who was not certificated, contacted an ARTCC controller while flying at 11,500 feet msl. After several exchanges about weather conditions, the controller asked if the pilot was above an overcast and needed clearance to descend through it. The pilot replied he was on-top. The controller then inquired about recent IFR training or experience; the pilot responded, 'I have not.' The pilot added, 'I have gone down through the clouds...we've never had a problem with it.' The controller advised that entering the clouds while flying VFR would be illegal. Shortly thereafter, the pilot stated, '...we've got a broken spot right here. We can dip down through.' No further communications were received from the aircraft.
Accident Sequence
Radar data indicated that the aircraft performed several altitude and heading changes before radar contact was lost. Witnesses reported corresponding variations in engine sound prior to impact. The airplane subsequently broke up in flight, with wreckage scattered over an area 1,600 feet long.
Examination Findings
Examination of the wreckage revealed that the stabilator and portions of the left wing had separated from the airframe due to overload failure.
Toxicology
Toxicology testing of the pilot's blood detected a trace of cocaine (less than 0.020 mcg/ml) and 0.129 mcg/ml Benzoylecgonine, a metabolite of cocaine. Liver fluid analysis showed 0.051 mcg/ml Benzoylecgonine.
