What happened
A charter flight departed from Las Vegas-McCarran Airport at 14:52 local time, destined for Monterrey. The aircraft was transporting 11 passengers and two pilots. During the cruise phase of the flight, while operating at FL370, the crew received clearance to climb through several flight levels, including FL390 and eventually FL410.
During this ascent, the aircraft type experienced a sudden and uncontrolled descent. The plane impacted the ground in an almost flat attitude within a desert region situated near La Rosita, Coahuila. The impact forces and a subsequent post-crash fire resulted in the total destruction of the airframe. There were 13 fatalities and no survivors among the occupants.
Findings
The investigation into the crash identified that the aircraft encountered severe atmospheric turbulence originating from an unstable weather system. A critical factor in the accident was that the crew was unable to identify the approaching weather phenomenon because of a malfunction in the onboard weather radar system.
