Narrative Report
On October 23, 2002 at 04:57 AM, Moscow - Bishkek experienced a crash involving Ilyushin II-62, operated by Tretyakovo Air Transport Company, with the event recorded near Bishkek-Manas Bishkek City.
The flight was categorized as positioning and the reported phase was landing (descent or approach) at a airport (less than 10 km from airport) crash site.
9 people were known to be on board, 0 fatalities were recorded, 9 survivors were identified or estimated. This corresponds to an estimated fatality rate of 0.0%.
Crew on board: 9, crew fatalities: 0, passengers on board: 0, passenger fatalities: 0, other fatalities: 0.
The listed crash cause is human factor. The aircraft departed Moscow-Domodedovo Airport on a positioning flight Bishkek-Manas Airport where cargo should be loaded. 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°). The plane passed over the runway threshold at a height of 30 metres and at a speed of 293 km/h. At this point the altitude should have been 15 metres. At a height of 20 metres, at a speed of 297 km/h, the thrust reversers of the n°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 metres. The nose then rose to a 7° 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° nose down elevator application. The plane finally touched down on the maingear wheels 1395 metres down the 4,200 metres long runway. The flight engineer, without telling the pilot in command, shut down the n°2 and 3 engines. With an elevator-down deflection of 10-11° and the stabilizer at -3,3° 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° nose-down attitude, the nose pitched down from +7° to -2,5° in 2-3 seconds. The stabilizer was then trimmed from -3,3° to +9° which caused the pitch angle to increase again. The Ilyushin ran off the left side of the runway 3,001 metres past the runway threshold. The plane continued until colliding with a concrete obstruction. The aircraft caught fire and burned out almost completely.
Aircraft reference details include registration RA-86452, MSN 16 22 2 1 2, year of manufacture 1976.
