Circumstances:
While approaching Mexico City-Benito Juarez Airport, the crew was cleared to descent from FL150 to FL120. In poor weather conditions, the crew continued the descent below FL120 when, at an altitude of 10,130 feet, the aircraft struck the slope of Mt Xocotlihuipa located 30 km east of the airport. The aircraft was destroyed and all four occupants were killed.
Probable cause:
Controlled flight into terrain after the crew failed to maintain FL120 as instructed by ATC while completing an IFR approach. It was reported that the copilot was not certified to act as a pilot on this type of aircraft. Also, the experience of the captain was limited.
