What happened
During departure from runway 14, the aircraft type utilized a rolling start. Observers noted that the plane rotated at the far end of the runway and maintained a high, nose-up attitude while remaining in ground effect. During this phase, the aircraft collided with an airport perimeter fence, a barrier wall, and several power lines. The impact with the wires caused them to be dragged through a nearby residential neighborhood, leading to further property damage. The flight ended when the plane crashed into a pasture, where it subsequently burned. There were no survivors recorded in the crash.
Findings
Investigation into the accident revealed that the aircraft was operating significantly above its permitted weight limits. The plane was loaded to a gross weight of 50,870 lbs, which exceeded the maximum allowable weight of 48,000 lbs for sea-level operations using antidetonation injection (ADI) fluid. Given the density altitude of 6,200 feet at the time of the accident, the maximum takeoff weight should have been much lower: 43,205 lbs with ADI and 15 degrees of flaps, or 38,909 lbs without ADI and 13 degrees of flaps.
Additionally, the flaps were found in the retracted position, though specific performance data for takeoff in that configuration was unavailable. Regarding the ADI system, while the tank was destroyed and the left engine line was damaged, no fluid was present in the right engine's line. The aircraft was operating under a ferry permit that did not authorize the transport of the two passengers or the cargo on board. Furthermore, the pilot in command had approximately 8 hours of experience in this specific aircraft model.
