Accident Sequence
At 1339 local time, the crew received clearance for takeoff from runway 32 at Tuxtla Gutierrez-Angel Albino Corzo Airport. During the initial climb, after being cleared to climb to 12,500 feet, the crew informed air traffic control that they were returning to the airport. Shortly thereafter, the aircraft began to lose altitude and crashed in a field. Upon impact, the aircraft burst into flames. The aircraft was totally destroyed, and all eight occupants were killed.
Probable Cause
The official investigation determined that the probable cause of the accident was an engine failure after takeoff due to a fuel pump malfunction. The crew elected to return, but the aircraft stalled because it was not maintaining sufficient speed. Contributing factors included poor engine maintenance and the fact that the crew initiated the flight while the aircraft's weight exceeded the allowable maximum takeoff weight.
