A twin-engine aircraft struck the slope of Mt Iztaccíhuatl while cruising in poor weather, resulting in the destruction of the airframe and the deaths of all 16 occupants on board.

What happened

While operating over the region of Puebla, the flight crew communicated their position to air traffic control and verified an altitude of 15,000 feet. Shortly after this exchange, the twin-engine aircraft encountered deteriorating weather conditions during its cruise phase. The airframe subsequently impacted the slope of Mt Iztaccíhuatl, a peak situated east of the capital city. The collision resulted in the total destruction of the aircraft, and all 16 occupants were killed.

Findings

Investigations conducted by Mexican authorities determined that the aircraft was not maintaining its assigned flight track at the time of the accident. Additionally, the crew was unable to visually identify the mountain due to poor visibility caused by adverse weather conditions.

Probable cause

The aircraft deviated from its assigned track and the crew failed to see the mountain due to poor visibility resulting from bad weather.
