What happened
During a nighttime departure bound for Mexico, the pilot of the aircraft declared an emergency and indicated an intention to return to the airport. While communicating via radio, the engines were heard operating at high power. Although the pilot confirmed that assistance was needed, he stated that a crash crew would not be necessary at that time.
Approximately one mile from the runway, the aircraft type struck power lines at an altitude of roughly 55 feet. The impact caused the plane to hit the ground, where it was subsequently destroyed by fire. Evidence from the nose door suggested the aircraft was in a vertical bank during the collision with the wires. There were no survivors, as the pilot, who was the only person on board, was killed.
Findings
An investigation of the wreckage showed no signs of mechanical failure or engine malfunction prior to the crash; however, the wreckage sustained significant damage from the post-impact fire. Investigators determined that the aircraft had been loaded in excess of its maximum certified gross weight. The collision was attributed to the pilot's inability to maintain proper altitude while maneuvering during the emergency, resulting in a flight path that intersected with transmission lines.
