Accident
After an uneventful flight from Mexico City, the crew commenced the descent to Monterrey–General Mariano Escobido Airport. Visibility was significantly reduced by heavy rainfall. The flight crew initiated a left turn to intercept the glideslope. After overflying the Monterrey VOR, the aircraft descended at a rate of 1,500 feet per minute while maintaining a speed of 250 knots. The aircraft subsequently struck the slope of Cerro del Fraile, which was located approximately 23 kilometers from the airport. The impact caused the aircraft to disintegrate. All 79 occupants on board perished. The wreckage was discovered at an elevation of 1,800 meters a few hours later.
Probable Cause
The official investigation concluded that the probable cause was a wrong approach configuration on the part of the flying crew, who initiated a left turn instead of a right turn as prescribed in the published procedures. Additionally, the aircraft's speed at the time of the accident was too high, which was identified as a contributing factor.
