What happened
During the descent phase of the flight, the aircraft experienced a sudden and severe structural failure. The failure resulted in the separation of the right outer wing, the horizontal stabilizer, and the vertical stabilizer from the main fuselage. Following this disintegration, the aircraft impacted the ground at a location situated roughly 10 miles away from its intended destination airport.
Findings
Investigations into the accident revealed that the aircraft was being operated at its maximum operating speed, known as Vne, during the descent. Additionally, data from radar and other investigative research confirmed that the aircraft was flying through an area characterized by known severe turbulence at the time of the structural breakup.
