An intercontinental flight from Bogot -Eldorado Airport (BOG) to Florencia and Neiva experienced a significant incident when a DC-9, departing Florencia at 18:00, encountered difficulties during its approach to the runway. The flight was cleared for a runway 01 approach, but the crew initiated gear and flap deployment, and the Neiva controller subsequently cleared the aircraft to land. A GPWS alarm was triggered, but the approach continued. The aircraft skidded to the left and right, requiring the crew to use rudder input to maintain control. Brakes failed to slow the aircraft sufficiently, resulting in a lateral drift, and the aircraft departed the end of the runway. Investigation suggests a likely cause related to the accumulated energy in the landing gear, leading to a 50% reduction in braking effectiveness, followed by a complete loss of braking due to the failure of the remaining landing gear components.An intercontinental flight from Bogot -Eldorado Airport (BOG) to Florencia and Neiva experienced a significant incident when a DC-9, departing Florencia at 18:00, encountered difficulties during its approach to the runway.
