Air India Plane Crash Report: Air India flight AI171 left for London from Ahmedabad on the morning of 12 June 2024. The flight was being operated by Boeing 787-8 Dreamliner aircraft. Shortly after the take-off, the aircraft collided with a medical college hostel, killing 260 passengers on the spot. This accident is not only one of the largest aircraft tragedies in India, but it is also considered to be the first fatal accident of Boeing 787-8 Dreamliner all over the world.

Now the Aircraft Accident Investigation Bureau (AAIB) has released a preliminary report of its 15 pages on this incident, which has revealed many important information related to the accident, but some secrets are still intact.

Both engines closed immediately after take-off!
According to the AAIB report, the fuel control switches of the two engines suddenly went from “Run” to “Cutoff”, 7 seconds after the aircraft take-off, which stopped fueling both engines. This entire process took place within a second. Due to this, the thrust of the engine went completely and the aircraft could not catch the height. It has been reported in the report that the pilots immediately tried to turn the engine again, understanding the situation.

Both switches were brought back to “run” and one of them also turned on, but by then it was too late. The aircraft crashed only 32 seconds after the take-off. In the cockpit voice recorder, a pilot was recorded asking the other, “Why did you cut fuel?”, I got the answer, “I did not.” But it was not clear which voice was from which pilot.

The aircraft was in a state of flying and pilots were also experienced
The report states that the aircraft was completely aircraft (flight). All necessary technical inspections were done before the take-off. Captain Sumit Sabharwal had a 15,000 -hour flight experience, with 8,600 hours at Boeing 787. He was accompanied by the first officer Clive Kunder in the flight, who also had 3,400 hours of experience. Both passed the pre-flight breath analyzer test and their presence in CCTV was also clearly visible.

The report also stated that FAA had issued a warning in the year 2018, in which the fuel control switch in Boeing aircraft had said that the locking mechanism was a possible failure. But this was not mandatory, only advice, so no action was taken on it.

Was it an electronic disturbance?
A big question is how the two fuel switches suddenly stopped together? Was it a pilot’s fault or any technical disturbance? Some aviation experts have feared that this may be due to malfunction in the MN4 microprocessor of the engine’s electronic control unit (ECU). A joint service bulletin released in 2021 by FAA and GE also identified the solder-ball fatigue of this microprocessor as a possible threat.

Due to this fatigue, the switches can be tripped on the cutoff automatically, which can suddenly stop, as in this accident.

Which questions are answered?
According to the report, the landing gear was not up during the take-off. It is possible that the pilot was busy dealing with the engine failure at that time and forgot to give a “gear up” call. In addition, there is no video recording of the cockpit, making it difficult to know who really changed the switch. Many experts have expressed concern over this and have demanded video recording in the future cockpit.

The report also stated that the Emergency Locator Transmitter (ELT) did not send any distress signal, while it had an impact of 3.2 to 3.5g at the time of the accident – which is usually sufficient to trigger the signal.

Investigation team and final report
Some pilot organizations questioned the expertise of the Aaib’s investigation team. In response, Aaib clarified that the team includes pilots, engineers, aviation medicine experts and flight recording experts, who are investigating the matter deeply.

Aaib has said that the final detailed report will be released by 12 June 2026. Till then, no clear conclusions have been drawn and no new security advice has been issued for 787-8 or GE GENX-1B engine operators.

Air India flight from Ahmedabad to London AI-171 crashed immediately after takeoff. The Boeing 787 Dreamliner aircraft was involved in this accident. There were 242 people in this aircraft. According to DGCA, this aircraft took off from Runway 23 at around 1:39 pm on June 12 today. At the same time, after a few moments of flying, the air traffic control was given a Mayday call, immediately after the call, the aircraft lost contact and the aircraft crashed at the airport itself.

Many questions arising after plane crash

After the Crashes of Air India Boeing 787 Dreamliner, many questions are being raised, in which many allegations are being made on Air India. People are raising questions about this plane how old this aircraft was. At the same time, how much is the life of Boeing 787 Dreamlineer.

How much is Boeing 787 Dreamliner’s life

At the same time, it is believed that according to normal flying, the life of Boeing 787 Dreamliner is more than 30 years. After which it needs a lot of maintenance. If its maintenance is done properly, then its life can be more, but if it is not maintained properly, then this aircraft can deteriorate before its life is completed or it may increase the chances of accident.

How old was the plane of Air India?

In such a situation, this aircraft was about 13 years old.

Have already risen on Dreamlineer

Questions have come in the last few years about many technical questions about the Dreamliner model. According to a report, an aircraft of this model in the US had to divert several times in about 25 days after hydraulic leakage and flap. Apart from this, many questions have been raised before the manufacturing of Dreamlineer.
