Aeroflot flight 411 was a scheduled flight from Moscow to Freetown in Sierra Leone that ended on July 6, 1982 with the crash of an Ilyushin Il-62 shortly after take-off.
course
The IL-62 took off at 12:31 a.m. local time with a high take-off weight of 164.5 tons from Moscow-Sheremetyevo Airport to the west. About eight seconds after the aircraft took off, the fire alarm for engine no. 1 was triggered and the pilots then switched the engine off. Thirty seconds later the fire alarm for engine number 2 was also triggered. This engine was also switched off. At this point the Il-62 had reached a height of 160 meters and a speed of 320 km / h. The pilots now initiated a right turn in order to return to the airport with the remaining two engines. While trying to maintain altitude, decreased speed until it to a height of 75 meters stall came. The plane hit the ground in a swampy forest area between the settlement of Mendelejewo and the village of Kluschino by 20 ° downwards and 70 ° to the left . 89 inmates died in the crash. A passenger who initially survived died two days later in the hospital from serious injuries and 60 percent burns.
Cause of accident
After examining the wreckage, it was found that all four engines were fully functional and the fire alarms were false. A pipe for the air conditioning system, which siphoned off the air from the engines, was broken and blew the hot air onto the engine's temperature sensors, triggering the false fire alarms. The pilots were not to blame because there was no standard procedure from the manufacturer for the flight with only two engines after take-off.
