Nigeria Airways DC-10 Training Flight Overrun at Ilorin Airport (5N-ANR)

Flight Details and Initial Approach A Nigeria Airways DC-10 departed Lagos, Nigeria, at 1320 local time for a training flight to Ilorin Airport. The crew consisted of a trainee captain in the left seat as pilot flying and an instructor captain in the right seat as pilot-in-command. The aircraft was fueled with 60.3 metric tonnes, providing an estimated endurance of eight hours. The flight proceeded normally until the aircraft entered the Ilorin control zone, where it was cleared for a touch-and-go on runway 05. ## Landing and Runway Overrun The aircraft was fully established on the instrument landing system (ILS) with landing gear down and flaps set at 35 degrees. The autopilot was disconnected at 400 feet above ground level, and the autothrottles were disconnected at 80 feet. The trainee captain crossed the runway threshold at approximately 60 feet or more, resulting in a late touchdown at about 2,913 feet (888 meters) from the threshold. Runway 05 had a landing distance available of 3,100 meters. The trainee captain did not fully recede the throttles for touchdown, requiring instructor assistance. The trainee also held the nosewheel off the ground, prompting the instructor to push the control column down. ## Aborted Takeoff and Accident After the nosewheel touched down, the trainee immediately requested takeoff power. The instructor began the aircraft reconfiguration procedure but was still working on required settings when the trainee raised an alarm as the runway threshold was approaching. The instructor, observing 900 meters of slight haze visibility, determined the aircraft would not take off with the limited runway available and deployed the spoilers while applying the brakes. The abort takeoff was not announced, and the engine throttles had already been advanced for takeoff. The aircraft was on heavy braking from about 1,390 feet (424 meters) before the runway end when it overran the runway. ## Impact and Aftermath The aircraft struck ILS antenna bars, electrical switch posts, and approach light support structures for runway 23, all located on the runway 05 clearway, before coming to a halt. The accident site was 44 meters to the left of the centerline and 649 meters along the extended centerline. A fire erupted and consumed the fuselage. All nine crew members escaped uninjured.
