What happened
During the landing phase on runway 06, the flight crew performed the arrival procedure on a surface that was notably wet. The aircraft approached the runway at an excessive speed for the conditions present. Upon making contact with the pavement, the captain initiated braking maneuvers; however, the pilot experienced a loss of directional control, which was attributed to a perceived aquaplaning event.
Following the loss of control, the aircraft veered toward the right side of the runway. The momentum carried the plane off the paved surface and down an embankment. The impact with the terrain caused the airframe to break into multiple sections. Despite the significant damage to the aircraft, all 83 occupants were successfully evacuated from the wreckage without any reported fatalities or injuries.
Findings
Investigations into the incident identified that the primary reason for the excursion was the excessive approach speed relative to the available landing distance. Additionally, investigators noted that braking performance was compromised because the application of the hand-brake caused the main wheels to become mechanically locked.
