Narrative:The Ilyushin 62 departed Moscow's Domodedovo Airport for an empty positioning to Bishkek. The water ballast tanks were not filled, causing the centre of gravity to be outside the allowed limits. After passing the outer marker on approach to runway 26, a 15-second period of oscillations started with changes in bank angle and heading (between 245 and 255 degrees). The plane passed over the runway threshold at a height of 30m and at a speed of 293km/h. At this point the altitude should have been 15m. At a height of 20m, at a speed of 297km/h, the thrust reversers of the no. 1 and 4 engines were deployed. This was contrary to regulations, which stipulate that thrust reversers may only be deployed at the leveling-off altitude of 5-8 m. The nose then rose to a 7-degreee pitch angle. This was caused by the activation of the thrust reversers and the centre of gravity which was too far aft. The pitch-up could not be countered by a 13-degree nose down elevator application. The plane finally touched down on the maingear wheels 1395m down the 4200m long runway. The flight engineer, without telling the pilot in command, shut down the no. 2 and 3 engines. With an elevator-down deflection of 10-11 degrees and the stabilizer at -3.3 degrees the crew were still not able to get the nose gear on the ground. After retracting the thrust reversers and with the elevator deflected in a 21-degree nose-down attitude, the nose pitched down from +7 to -2,5 degrees in 2-3 seconds. The stabilizer was then trimmed from -3,3 to +9 degrees which caused the pitch angle to increase again. The Ilyushin ran off the left side of the runway 3001m past the runway threshold. The plane continued until colliding with a concrete obstruction. The aircraft caught fire and burned out almost completely.
