Investigation of Air India-Boeing Aircraft Aircraft: Days after the publication of a report on air accident investigation (AAIB), the media socket claimed that investigators were studying a possible hitch in electric and software components of the aircraft that could run “unusual” actions.
The “probe detects the” endless transition “of the fuel control switches to the marginal mode of the second after raising,” Indian Express said.
“Cut down the fuel”: What did the AAIB message reveal to Air India Crash?
The AAIB report published on July 12 claimed that the Air India -linked flight to London experienced seconds of “cut -off fuels” after takeoff from Ahmedabad’s Sardar Vallabhbhai Patel of International Airport (VAAH) 12 June.
According to the voice cockpit record, the pilot denied the cutting of the fuel. One pilot was heard when he asked, “Why did you cut off?” To which the other replied, “I didn’t do it.”
Two switches on the flight deck control the fuel supply to the engine. Switching to “cut-off” is usually done only after landing.

They are used by pilots to start or turn off the engines on the ground or to manually shut down or restart engines if the engine fails during the flight. Aviation experts say that the pilot would not be able to accidentally move fuel switches that feed the engines.
In order to turn on the fuel power, the switch must be pulled out and then moved to the “run” position, where it is released and settled back to the locked position. To turn off the fuel power, the switch must be pulled out, moved to the “marginal” position and then re -released.
London-bound Boeing 787 Dreamliner crashed into a medical faculty hostel in Ahmedabad moments after take-off from the city airport and killed all of them except one of 242 on board and another on Earth in the deadliest air accident in ten years.

“Stabilizer converter defect”
According to Indian Express, just a few hours before takeoff from Ahmedabad to London Gatwick 12th, a pilot flying by the same aircraft from Delhi to Ahmedabad recorded in the technical protocol “Stabilizer convex defect”.
The stabilizer position converter is essentially a sensor that controls the pitch of the aircraft – nose movement up and down – and transmits data in electric signals to the flight control system to ensure that there are accurate responses to the pilot input.

The clerk said Indian Express that the failure was checked and the engineer had made problems with the shooting according to the Boeing procedure.
“The failure is a critical problem because it can provoke incorrect responses in flight control, including an unintended fuel restriction signal,” the clerk said.
He added, however, “The stabilizer position failure did not cause this accident, but the question is whether this has led to multiple sensors failure.”
“Endless Transition”
The official claimed that the plane had previously experienced two main hits, including the cancellation of the flight as a result of the “unsolvable electric hitch” in December 2024 and an emergency landing in 2015 due to the increase in the air compressor (CAC), the known improper function on Dreamliner.
The clerk said that air data analysis would focus on the “trail of errors” as stated in the technical protocols to detect the health of electrical and software components of the aircraft.

The official allegedly stated that the engine indication and the crew alerts (EICAS) aircraft in some years of the previous flight Ahmedabad-Gatwick in June 12 showed some system warnings.
“The probe is to make sure the switches are released due to anomaly or whether the FADEC engine (full of the digital engine) (the brain of the aircraft) is non -functional because the microprocessor could incorrectly interpret commands and initiate uncontrolled actions,” he quoted.
Investigators are therefore likely to immerse themselves in the “history of technical error” or disorder during the aircraft life, the clerk said.
