Détails:
Baikal Airlines flight 130, a Tupolev Tu-154M, crashed after takeoff from Irkutsk Airport, Russia. The aircraft operated on a service to Moscow's Domodedovo Airport.
On the apron at Irkutsk, it took 17 minutes to get all three jet engines to run. During the start-up of the centre (no. 2) engine, a spontaneous rotation of the engine's turbo compressor was noted twice. When all engines were started the "dangerous rotation of starter" warning light illuminated. The light wouldn't go out by using the starter turn off button. The operations manual didn't describe the actions to be taken in this situation and the crew thought the warning was false, thinking the starter could only spin during engine start-up. All engine parameters seemed normal and the crew decided to continue.
The aircraft took off from runway 12 at 11:59 hours local time. Four minutes after takeoff the starter if engine no.2 suffered an uncontained failure. Turbine fragments severed fuel lines and a fire erupted in the area of the APU and the no.2 engine. The flight crew shut down engine no.2 and activated all three fire extinguishing bottles. The fire however could not be controlled.
At 12:05 the flight crew radioed that they had an engine fire and were returning to the airport. Meanwhile the fire caused damage to hydraulic lines, which led to a loss of hydraulics.
Control was lost and the aircraft crashed amongst farm buildings.

Probable Cause:

PROBABLE CAUSE: Break-up of the no.2 engine starter, damaging fuel and oil lines. The crew shouldn't have departed in the first place, but underestimated the severity of the situation "due to shortcomings in the operational documentation and the instructions used for the training of flight and technical personnel, as well as the unsatisfactory information provided in the cockpit by the starter's status monitoring system."
