U.S. officials believe the captain of the crash air Indian jet may cut off fuel supply.
According to the U.S. assessment of black box data, the first officer who drove the Boeing 787-9 questioned why the captain moved the switch to the cutoff position.
According to the Wall Street Journal, the first place reportedly expressed surprise and panic while the captain remained calm.
All of the 242 people on the Boeing 787 Dreamliner were killed last month when the plane took off from Ahmedabad Airport.
This comes after a preliminary report released by the Aircraft Accident Investigation Bureau (AAIB), which found that switches that controlled the flow of fuel to the jet were turned off, causing catastrophic losses during takeoff.
According to the report, one pilot was heard asking another why you “cut off” the fuel supply from the recycled cockpit recording. Another pilot replied that he was “no”.
It was not clear who said what. But, sources reviewing cockpit recordings in the United States told the Wall Street Journal that it was the captain who was asked why the engine was cut off.
The report said the switches moved continuously, one second apart. After about 10 seconds, the switch is turned on again. The report did not disclose whether the switch could have been intentional or intentional.
Co-pilot Sumeet Sabharwal and Clive Kundar have more than 9,000 hours of flight time between the co-pilot.
On Sunday, the telegraph revealed that Air India collapse investigators were studying Mr Sabaharwal’s medical records because he claimed he had depression and mental health problems.
Captain Sabawar, 56, has been considering leaving the airline to take care of his older father after his mother dies in 2022.
At the moment before the disaster, Mr. Sabawar sent out a Mayday call. However, all contact was lost after the plane reached a maximum altitude of only 400 feet above the runway. Then the plane fell to the ground and exploded and hit.
Air India CEO Campbell Wison said in a staff memo that the report “caused a round of speculation in the media.”
Mr Wilson said the report found no cause and made no recommendations and urged people to avoid reaching premature conclusions because the investigation is far from over.
However, Indian media reported that investigators are investigating potential electrical and digital failures that could trigger “all-inclusive” actions.
According to reports, an official realized that the investigation said: “The investigation will determine the possibility of a ‘unqualified transition’ of fuel control switches to a cutoff mode after the lift.”
The newspaper said a few hours before the takeoff, a pilot flew from Delhi to Ahmedabad in a technical log that “the stable position transducer defects”.
A stabilizer position sensor is a sensor that controls the nose of an aircraft to move up and down and transmits data to a flight control system. The official said the fault was checked and the engineers troubleshooted it.
“The failure is a key issue because it can trigger incorrect responses in flight control, including unexpected fuel cutoff signals,” the official said.
The newspaper said at least two similar incidents occurred on the plane in the weeks before the crash.
A false fuel system warning involving a false alarm that flashes on the screen of the aircraft control panel. Another is the electrical fault that causes the flight to be cancelled.
The official added that the plane had experienced two major problems before, including an emergency landing in 2015 due to problems with the cabin air compressor.
The Indian Federation of Pilots expressed dissatisfaction with pilot representatives and was excluded from the investigation process, saying: “We are also firmly opposed to the way preliminary reports that are publicly interpreted and presented publicly.”
Federal President Captain CS Randhawa said: “The report lacked comprehensive data at the time of publication and seemed to rely on interpreted cockpit recordings to prompt pilots for errors and question the professional competence and integrity of the pilots.
“This approach is neither objective nor complete. Prioritize the blame to premature and irresponsibility before a thorough, transparent and data-driven investigation.”
The crash was Boeing’s first fatal accident. However, the airline has suffered reputational losses after a series of safety and quality issues.
Dreamliner entered service in 2011 and is popular among commercial airlines and is often used for international long-haul routes.
