Incident Overview
Description
The DC-10 was operating on a flight on behalf of L¡neas Areas Suramericanas when it was cleared to land on Bogot ‘s runway 13L (12467 feet/3800 m long) . It reportedly hit a pot hole in the runway. The plane overran the runway, striking ILS localizer equipment. The left hand horizontal stabilizer was almost completely sheared off, as was the undercarriage. The DC-10 came to rest in a field with substantial damage to the underside of the fuselage and wings. The no. 1 and no. 3 engines had broken loose from the wings. CAUSAS: “Salida de la pista de aterrizaje 13 izquierda del aeropuerto El Dorado como consecuencia de un aterrizaje con una velocidad de unos 180 nudos y a 1500 pies de distancia del umbral aproximadamente, en el cual no se emplearon los spoilers y en el que hubo presencia de hidroplaneo en los conjuntos del tren de aterrizaje principal haciendo que la acci¢n de frenado fuese inferior a la prevista. La decisi¢n de la tripulaci¢n de continuar la aproximaci¢n a pesar de que esta no estaba estabilizada de acuerdo con los criterios descritos en el manual general de operaciones de la compa¤¡a explotadora. La omisi¢n de puntos de la lista de chequeo y call out por parte de la tripulaci¢n que trajeron como consecuencia una menor alerta situacional frente a los par metros de la aproximaci¢n y de supervisi¢n de la operaci¢n de sistemas clave como el de la extensi¢n de spoilers luego del aterrizaje. La no respuesta ante la alarma del sistema de proximidad del terreno que se activo al menos en cinco ocasiones durante la aproximaci¢n final en dos modos diferentes.” PROBABLE CAUSE (translated from original Spanish report): Departure from runway 13 left the El Dorado airport as a result of a landing with a speed of 180 knots and 1500 feet from the threshold, during which the spoilers were not used and in which there was hydroplaning by the main landing gear making the braking action less than expected. The decision of the crew to continue the approach despite the fact that this was not stabilized in accordance with the criteria described in the manual of operations of the airline. The omission of points in the checklist and call out from the crew that resulted in a lower alert situation facing the parameters of the approach and monitoring the operation of key systems such as the extension of spoilers after the landing. The non-response to the ground proximity warning system that is sounded for at least five times during the final approach in two different modes.
Primary Cause
The incident was likely caused by a sudden and unexpected loss of control due to the impact of a pot hole on the runway. The pilot?s decision to continue the approach despite the unstable conditions, compounded by a lack of proper checklist procedures and a failure to respond to critical alerts, contributed to the hazardous situation. The pilot’s actions to continue the approach without sufficient checks and warnings significantly increased the risk of a catastrophic outcome.The incident was likely caused by a sudden and unexpected loss of control due to the impact of a pot hole on the runway.
