What happened
The incident occurred immediately after departure while the aircraft was in the initial climb phase. During this period, the flight path intersected with a thunderstorm cell that generated severe turbulence. The aerodynamic forces exerted by the turbulent air exceeded the structural limits of the airframe, leading to the catastrophic failure of the left wing near the engine section. Following this structural disintegration, the aircraft lost control and impacted the ground in a nearby field. All 22 occupants were killed in the crash.
Findings
Investigations determined that the primary factor was the interaction between the aircraft and the weather conditions. The turbulence associated with the thunderstorm activity placed excessive stress on the left wing structure. This stress resulted in the wing breaking off shortly after takeoff, which directly led to the loss of the aircraft.
