On December 23, 1984, a Tupolev Tu-154 crashed on Aeroflot flight 3519 from Krasnoyarsk to Irkutsk during an emergency landing , killing 110 of the 111 occupants.

plane

The aircraft was a five-year-old Tupolev Tu-154B-2 with the air vehicle registration CCCP-85338, the three engines of the type Kuznetsov NK-8-2 was equipped.

crew

The crew consisted of 3 flight attendants, the flight captain Viktor Semjonowitsch Falkow, the first officer Yuri Petrovich Belavin, the flight engineer Andrei Wassiljewitsch Resnitschki, and the navigator Gennadi Leonidowitsch Oserow.

course

At 6:08 p.m. Krasnoyarsk time, the plane took off from Jemelyanovo Airport . The aircraft then made a right turn on the instructions of the air traffic controller and climbed to 1,500 m . The air traffic controller then cleared the aircraft for a climb to 5,700 m. About two minutes after take-off, the first low-pressure compressor disc of engine no.3 (right) broke at an altitude of 2,040 m at a speed of 480 km / h , with the debris including the fuel lines and the electrical lines to engine no.3 cut, which then caught fire. The aircraft tilted to the right, whereupon the pilots steered against it and stopped the climb at an altitude of 2,150 m. Then the pilots turned back for an emergency landing . Shortly afterwards, the flight engineer reported vibrations in engine no. 2 (center) and switched it off. In order to reduce the speed, the captain gave the instruction to idle engine 1 (left) and engine no.3, as a result of which the flight engineer noticed about ten seconds later that engine no.3 was not working and he mistakenly switched engine no. 2 had switched off, whereupon he tried to restart engine No. 2. The pilots switched off engine no. 3 and activated its engine extinguishing system, which, however, was not sufficient to extinguish the fire. Suddenly engine no. 2 accelerated to takeoff thrust ; the thrust levers had no effect and the pilots also shut down engine # 2, but did not close the fuel valve. Meanwhile the fire had spread to the cavity of the pylon and into the stern, where the auxiliary power unit is located. The fire continued to spread to engine # 2. The flight engineer reported a fire in engine number 2. The aircraft flew over the ILS outer marker at an altitude of 175 m at a speed of 420 km / h. The voltage dropped due to the damage to the power supply from the fire. The hydraulics failed eleven seconds before the impact, which made it impossible to control the aircraft, which then rolled to the right and sank at a rate of 10 m / s. It struck at 6:15 p.m., 3,200 m from the runway threshold , at a speed of 425 km / h, a rate of descent of 22 m / s and a bank angle of 50 °, four minutes and 30 seconds after the start of the emergency . All seven crew members and 103 of the 104 passengers died; a 27-year-old inmate was rescued.

root cause

As a cause of the breaking of the first low-pressure compressor disk of engine no. 3 was fatigue , by a metallurgical error caused by a nitrogen impurity in the metal, and by processing errors detected. The actions of the captain, first officer and navigator were not criticized. However, the flight engineer was criticized for not closing the fuel valve on engine # 3, which was against the regulations and resulted in the fire spreading and eventually destroying the hydraulics.
