What happened
During an arrival at Sana'a Airport, the aircraft entered its final approach in a nose-down orientation. This attitude caused the nose gear to make contact with the runway surface before the main landing gear.
As the aircraft touched down, it underwent four distinct bounces before establishing a firm connection with the runway. Following this impact, the crew was unable to decelerate the vehicle within the available runway length. The subsequent overrun led to the separation of the undercarriage from the airframe.
Despite the severity of the excursion and the fact that the aircraft sustained damage beyond repair, all 18 occupants were able to evacuate the scene without sustaining any injuries.
Findings
Investigations into the incident concluded that the primary factor was an incorrect approach configuration maintained by the flight crew during the descent.
