Runway Overrun and Off-Runway Slide in Heavy Rain (N70773)

Incident Overview and Sequence of Events The aircraft executed a firm landing in heavy rain, touching down approximately 1,050 feet past the approach end of runway 18. The crew's attempts to stop the aircraft were ineffective. Believing the aircraft was about to leave the runway, the captain used differential power and rudder to turn the aircraft to the left. The aircraft then slid off the end of the runway, passed through a US localizer antenna building, struck a dirt blast mound, and slid up over it. It came to rest with the nose section in the perimeter road between the blast mound and a river levee. ## Injuries and Damage Of the 60 passengers and 6 crew members aboard, three passengers and two crew members sustained minor injuries. The aircraft sustained substantial damage, but no major fire occurred. The passengers and crew evacuated the aircraft without major difficulty.
