Circumstances:
While cruising at an altitude of 6,100 meters on a flight from Moscow-Vnukovo Airport to Sochi-Adler Airport, the generator on engine number three failed. Debris punctured a hydraulic line and the fluid caught fire while in contact with high temperature elements of the engine. As the fire extinguishing system failed to work properly, the crew decided to shut down all three other engines and completed a gear up landing in a field. The airplane slid for several yards and came to rest. All 97 occupants were evacuated safely.
Probable cause:
Failure of the generator on engine number 3 for unknown reason. This caused the rupture of a hydraulic line and the fluid caught fire while contacting engine elements. The reason of the dysfunction of the fire extinguishing system remains unknown.
