Incident Overview
En route from Calí to Villagarzón, the crew contacted air traffic control and reported technical issues with the left engine. They were cleared to divert to Pasto-Antonio Nariño Airport. The crew modified their route and started a descent.
Landing and Overrun
During the approach, the flaps were lowered to 38° and the speed was reduced to 250 km/h. After the landing gear was selected down, the speed increased to 270 km/h, prompting the selection of full flaps. The aircraft touched down on runway 02, which is 2,312 meters long. It was unable to stop within the remaining distance. The aircraft overran the runway, descended a 15-meter-high embankment, and came to rest broken in two with its left wing torn off. All 53 occupants were rescued; a few sustained injuries.
Probable Cause
According to the official investigation, the probable cause was stated as follows: "Taking into account that the operator failed to cooperate with the investigators by sending the necessary documentation on the anti skid system, the braking system, as well as the propellers and did not manage the reading of the flight recorders; the available evidence establishes as POSSIBLE CAUSE the failure of one or some of the related systems above; in addition to the inadequate operation during the single-engine landing, which finally produced the departure of the aircraft at the end of the runway."
