What happened
The aircraft experienced an in-flight breakup while operating on a cross-country flight plan. During the operation, there was evidence of thunderstorm activity and turbulence present along segments of the planned route. However, meteorological reports indicated that no known adverse weather conditions existed in the immediate vicinity of the crash site.
Approximately 25 miles southwest of the location at Kirksville, Maryland, weather observations recorded at 0745 CST showed scattered clouds at 8,000 feet and overcast skies at 15,000 feet. Visibility was reported at 20 statute miles with winds from 090 degrees at 15 knots.
The investigation
A detailed examination of the wreckage revealed significant structural failures consistent with extreme aerodynamic loads. Both wings had failed upward and aft relative to the aircraft's fuselage structure. Additionally, the stabilators had separated downward in relation to the airframe.
The distribution of debris indicated a violent disintegration. The left wing and the stabilators were located approximately 1-3/4 miles from the main wreckage cluster. The pilot's body was discovered about 1/4 mile away from the primary impact zone, while the passenger was found still strapped into their seat within the wreckage.
