On January 3, 1994, a Tupolev Tu-154 M crashed on the domestic flight Baikal Airlines Flight 130 from Irkutsk to Moscow . All 124 inmates and one person on the ground died

plane

The aircraft was a 5 year old Tupolev Tu-154M with the air vehicle registration number , the RA 85656 with three Solovyov 30 D- Ku-154-11 engines equipped.

course

Sudden turbo-compressor rotation was noted twice while starting engine No. 2 (center) . Then a warning light went on, which showed that the starter was still turning, which did not go out even after it was switched off. There were no prescriptions for treatment of this disorder. The cockpit crew (captain, co-pilot, flight engineer and navigator) thought the warning light was a false warning because they believed that the starter could only turn when an engine was started . All engine parameters were normal, and the aircraft took off at 11:59 in the direction of Moscow from. But 3 minutes and 45 seconds after take-off, at an altitude of 4000 meters, the air starter activated itself and began to rotate at a supercritical rotational speed of more than 40,000 rpm until the air starter's disk broke. The debris damaged the hydraulic lines and the fuel lines to engine no. 2, which then failed. In addition, a fire broke out in the engine, which then damaged the control surfaces and the hydraulic lines. The pilots attempted an emergency landing in Irkutsk . A warning sounded in the cockpit about an engine fire in engine No. 2. Although the pilots operated the engine extinguishing system, the fire could not be extinguished. Eventually the hydraulics failed completely, and at 12:08:38 local time the aircraft hit a speed of 510 km / h between farms near Marmony, 15 km northeast of Irkutsk Airport. All 124 inmates and a farmer on the ground died.

root cause

The cause of the accident was the bursting of the air starter while climbing , which damaged fuel lines and caused a fire, which then damaged control surfaces and hydraulic lines and made the aircraft uncontrollable. The cockpit crew should not have taxied to take off, so they underestimated the seriousness of the warning. In the operating manuals , however, there were no procedures to be followed for this incident, and the cockpit displays did not provide any further information on the condition of the air starter.
