Narrative:Cubana Flight 389 was preparing for departure back to Havana with a planned en route stop at Guayaquil. During the first engine start a pneumatic valve was blocked. The problem was rectified and two engines were started with ground power. The third one was started as the Tupolev taxied to the runway. After obtaining takeoff clearance, the throttles were advanced and the airplane accelerated down runway 17. When the aircraft reached the Vr speed, it would not rotate. It took the crew 10 seconds to decide to abort the take-off. With 800 m of runway length remaining, brakes were applied. The Tu-154 overshot the runway, plowed into a soccer field. The plane barely missed a middle-income residential area.

It is presumed that because of the problems during start-up and the time, almost 38 minutes, that passed to the beginning of take-off, the final point of the checklist for taxiing was not complied with and the crew forgot to select the switches for the hydraulic valves of the control system.
