What happened
During the flight, the aircraft's right wing suffered a complete structural failure. This loss of aerodynamic integrity caused the plane to enter an uncontrolled dive. The sequence ended when the aircraft struck the ground, triggering a massive explosion at the crash site.
There were three fatalities among the crew members on board. No other persons were reported in the aircraft during this event.
Findings
Investigations into the accident concluded that the right wing failed while the aircraft was en route. The primary reason for the collapse was a structural failure of the wing's components. This breakdown was attributed to material fatigue resulting from the aircraft being operated in ways or environments for which it was not designed.
