The Sabreliner cargo jet operated on a flight from Culiac n to La Paz, Mexico, carrying 1000 kgs of cargo. The departure was rushed because the crew had very limited time due to the fact that the airport would be closed shortly during the presidential visit. At 09:40 the flight was cleared for takeoff from runway 02. During the initial take-off phase and at a speed of 60 miles per hour, the aircraft moved sideways. The pilot attempted to raise the nose twice, but the aircraft would not lift off the runway. Twelve seconds later the takeoff was aborted, but at that moment there was approximately 300 meters of runway left. The airplane continued off the runway and crashed into cars on the Culiac n-Navolato highway, killing seven persons on the ground. Culiac n has a single asphalt runway, measuring 2300 x 45 meters. Weather was fine at the time of the accident. PROBABLE CAUSE: “Runway excursion, impact and fire as a result of a configuration unsuitable at the time of take-off.” CONTRIBUTING FACTORS: – Lack of training. – Lack of CRM. – Crew pressure to perform the operation before the airport closure. – Omission of procedures. – Possible stabilizer failure. – Lack of adequate supervision of operations by the company.
