What happened
The incident occurred during a flight segment from Villahermosa to Veracruz. The crew communicated their position to air traffic control shortly before the event. While cruising at an altitude of 11,000 feet, the aircraft encountered heavy rainfall. During this period, the twin-engine plane struck the slope of a mountain situated near San Andrés Tuxtla.
The impact forces resulted in the destruction of the airframe. All 11 occupants on board were killed in the accident.
Findings
Official investigations determined that the crash was the result of a controlled flight into terrain. Adverse weather conditions, specifically those associated with a hurricane affecting the region at the time, almost certainly caused or contributed to the collision.
