“According to preliminary data, the cause of Air India’s aircraft disaster, which happened last month and claimed the lives of 260 people, was the cessation of fuel supply to engines. Investigators will continue to decrypt the voice from the pilot’s cabin to understand who exactly and why the fuel switch turned off.”, – WRITE: www.pravda.com.ua

Investigators were able to obtain data from the “black boxes” of the aircraft, including 49 hours of flight data and two hours of audio recordings from the cabin of pilots, including from the moment of the disaster.
According to the report, the aircraft reached a speed of 180 knots, when the switches of stopping fuel on both engines were “transferred from Run to the CutOFF position one by one with a break at 01 second.”
The report notes that “on the voice record from the cabin to hear one of the pilots asks the other why he turned off the engines. The other pilot replied that he did not do it.”
Shortly afterwards, the switches were turned back and the engines were in the process of re -launching when the accident occurred.
At the time of the disaster, one engine restored the thrust and the other has not yet restored power.
In the aircraft, the fuel cutting cuts are between the chairs of two pilots, immediately behind the throttle levers. They are protected on the sides by a metal bar and have mechanisms of locking.
