What happened
While traveling from La Paz to Palmira, the flight crew received notification from air traffic control that Palmira Airport was unavailable for landing because of adverse weather. Consequently, the decision was made to divert the flight to Trinidad-Jorge Heinrich Arauz Airport.
During the approach and descent phase, the four-engine aircraft experienced a sudden loss of control. The plane struck a mountain slope located a short distance from the destination airport, impacting with enough force to ignite a fire. The impact resulted in the total destruction of the airframe and the deaths of all five occupants.
Findings
Investigation into the accident revealed that an unidentified fire broke out inside the cabin during the descent. This fire released fumes that incapacitated the crew, leading to the loss of control of the aircraft.
