Accident Sequence
Radar data showed the airplane cruising at approximately 7,500 feet MSL with a ground speed of 190 knots and tracking about 140 degrees, when it began to descend. The last recorded altitude was about 6,500 feet MSL. Witnesses heard a loud noise and observed the airplane and debris falling to the ground. They were unable to judge the altitude at which the airplane broke up.
Wreckage Examination
Wreckage was scattered over a distance of about 1.3 miles. Examination revealed that the V-tail stabilizers and wings had separated in flight. There was evidence that the stabilizers had failed in a downward direction. The right wing separated from the fuselage at the wing root, and the left wing separated in three main pieces. Evidence on the front spar carry-through structure indicated the wings had failed in a downward direction.
Cockpit and Pilot
Both front seat belts were intact but unlatchched, with no evidence of deformation. The pilot was thrown from the airplane during the accident.
Airframe Condition
No pre-accident anomalies of the airframe were found.
