In the dialogue that the two pilots of the fatal flight 171 had Air indiawhich crashed on June 12thus losing their lives 260 people, researchers focus on preliminary research on the causes of the crash.

A few seconds after take-off, both Boeing 787 Dreamliner fuel control switches moved abruptly to the “cut-off” position, which means that the fuel was stopped to the engines, causing total power loss. The transition to the “cut-off”, that is, to stop fuel, is a move that is usually made only after landing.

The recording in the cockpit records one pilot to ask the other why “did you stop the benefit?” The second person replies that he didn’t. The recording does not specify who said what. At the time of the take -off, the co -pilot was flying the aircraft while the commander was watching.

The switches returned to their normal flight position, activating the automatic re -opening of the engine. At the time of the crash, one engine was recovering while the other had begun, but had not yet regained power.

Air India’s Flight 171 was flying for less than 40 seconds before crashing into a busy neighborhood in Ahmedabad, western India, marking one of the most enigmatic air disasters in India.

Researchers are looking for debris and pilot recordings to figure out what went wrong immediately after taking off. Air India’s flight rose to 625 feet with clear weather before losing location data 50 seconds later, according to Flightradar24. Saturday’s 15 -page exhibition offers early information.

The investigation – led by the Indian authorities, with experts from Boeing, GE, Air India and Indian regulators, along with participants from the US National Transport Security Council and the United Kingdom – also raises a number of questions.

Researchers say that the safety lever switches are designed to prevent random activation – they must be pulled upwards to unlock, a security feature dating back to the 1950s. Made according to strict standards, they are extremely reliable. Their protective bases offer further safety from random blows.

“It would be almost impossible for both switches to be pressed with a single hand move, and this makes it unlikely to accidentally activate,” Canada -based air accident researcher, who wanted to remain anonymous, told the BBC.

“Therefore, the question arises why the pilot, any pilot, put the switches on the off position,” said Shawn Pruchnicki, a former air accident researcher and aviation expert at the University of Ohio.

“Was it appropriate or a result of confusion? This seems unlikely, as the pilots did not report anything unusual. In many emergency situations in the cockpit, pilots may press wrong buttons or make the wrong choices – but there was no indication of such a situation here, nor any discussion indicating that fuel switches were accidentally selected. This kind of error usually does not occur without any obvious problem, “he told the BBC.
