Examination of the wreckage following removal from the accident site was conducted at the Reynolds Airport in Jackson, and later at the Lear Jet facility at Wichita, Kansas.
Portions of all major parts of the structure and flight controls were found in the impact area. In most cases the heavy fittings and actuators were found completely separated from all attaching structure. Parts of both nose section access doors, and pieces of all cabin windows, the cabin door, and fragmented pieces of the windshield Were all identified.
Within the impact area the horizontal stabilizer was recovered in many pieces, including the tip fairlngs and the center hinge and surrounding rib structure. The hinge pin had separated from the left rib and remained in the right rib with portions of vertical stabilizer attach fittings still intact The stabilizer Jackscrew was in the normal range between 0 and 0.5-degree nose-down. Portions of all the flight controls and most of the attaching hinges were identified, With no evidence of pre-impact failure. The landing gear, flaps, and spoilers were determined to have been retracted at impact.
Both aircraft engines incurred severe flattening and accordioning in the fore and aft axis. They revealed rotational scoring, but the various indices of power being developed were contradictory.
The aircraft generators both exhibited rotational scoring on the drive end. The generator leads to the electrical load center showed no arcing, heat, or fire damage. The nacelle heat relays showed very slight fire damage but no signs of operational distress. Both batteries had fire damage on the left terminals, but there was no sign of electrical arcing. Pieces of both static inverters were recovered with no evidence of fire or heat damage.
