Accident Details
On final approach to Tuxtla Gutiérrez Airport runway 35, the aircraft was fully configured for landing. The crew decided to initiate a go-around procedure for unknown reasons and completed a left turn in an attempt to make a 180 circuit. During this maneuver, the aircraft lost height, struck trees, and crashed 3,200 meters short of the runway threshold. The impact ignited a fire.
Casualties and Injuries
All four crew members and 20 passengers were killed. Sixteen other occupants sustained injuries.
Probable Cause
According to the official investigation, the probable cause of the accident was a loss of control on final approach resulting from a loss of lift after the crew failed to maintain a minimum speed while initiating the go-around procedure. At the time, the aircraft was fully configured for landing with flaps and landing gear down.
Contributing Factors
The investigation identified two contributing factors: lack of crew coordination and lack of crew experience on this type of aircraft.
