What happened
During an approach in heavy rainfall, the aircraft type performed a firm touchdown approximately 1,050 feet beyond the threshold of runway 18. Following the landing, the crew attempted to decelerate the plane, but these efforts failed to stop the movement. Recognizing that the aircraft was heading toward the end of the runway, the captain applied rudder and differential power to steer the plane toward the left side of the pavement.
The aircraft subsequently exited the runway surface and collided with the building housing the US localizer antenna. After this impact, the plane struck a dirt blast mound and climbed over it before coming to a final stop. The nose of the aircraft ended up positioned in the perimeter road, situated between the blast mound and a nearby river levee.
Of the 60 passengers and 6 crew members on board, there were five total injuries (three passengers and two crew members), all of which were classified as minor. While the aircraft sustained substantial damage, no significant fire broke out during the event. The evacuation of all occupants was completed without major complications.
Findings
Investigation into the incident determined that the primary factor leading to the overrun was hydroplaning of the landing gear wheels, which prevented the braking system from functioning effectively.
