Accident
The pilot had just taken off at night on a flight to Mexico when he declared an intent to return and land due to an unspecified emergency. While communicating by radio, both engines were audible running at high power. When asked if he required assistance, he replied affirmatively, but when asked if he required a crash crew, he replied negatively. Shortly thereafter, the aircraft collided with power lines approximately one mile from the runway, impacted the ground, and was demolished by fire.
Impact details
The collision with the power lines occurred at about 55 feet above ground level. A wire impact mark on the nose door indicated that the aircraft was in a vertical bank at the time of the collision.
Examination
An examination of the wreckage revealed no evidence of a preimpact mechanical malfunction or failure. However, there was extensive damage from fire. Additionally, there was evidence that the aircraft was loaded beyond its maximum certificated gross weight.
Pilot
The pilot held a temporary U.S. license based on his Canadian license.
