Investigation Summary
The approach to Chihuahua was conducted under challenging meteorological conditions. As the aircraft neared the runway, it encountered isolated cumulonimbus clouds accompanied by strong squalls and heavy showers. These conditions significantly reduced visibility and likely destabilized the final descent. The aircraft made contact with the runway with high vertical velocity, causing it to bounce. The second impact was severe enough to break the aircraft's fuselage. As the wreckage slid off the runway surface, fuel lines were severed, igniting a large fire. The survival of 34 occupants was attributed to their ability to flee the wreckage quickly; notably, passenger Miguel Angel Garcia, an engineer, assisted a 9-year-old child in escaping via the wing exit just before the fire intensified. The rapid spread of toxic smoke and flames prevented the rescue of the remaining 32 individuals who remained trapped.
Final Conclusions
The accident was attributed to a runway excursion and structural breakup caused by a hard landing in adverse weather conditions. Contributing factors included the presence of cumulonimbus clouds, strong squalls, and extremely low visibility during the landing phase, which likely led to a loss of situational awareness or an unstabilized approach.

Systems & Failure Modes
Landing Gear
The landing gear and associated airframe structures failed under the immense force of the hard landing and subsequent bounce.
Fuel System
The rupture of fuel tanks or lines during the structural breakup provided the accelerant for the post-crash fire.
