Engine 1 and engine cut within 2 1 second: What happened due to Air India plane crash? 10 major conclusions from investigation report | Bharat News
New Delhi: Aircraft Accident Investigation Bureau of Investigation (AIM) released its preliminary report in the tragic accident of Air India 171 in Ahmedabad on Saturday, June 12, killing 260 people.The preliminary report of the 15-pests released a month after the tragic accident, the Air India flight gives the initial findings and current status of the investigation in the AI171 accident, which is bound to the Boeing 787–8 Dreamliner London Gatwick. The plane crashed a few moments after the takeoff, slamming at a medical hostel complex near the airport. Of the 241 people, only one passenger survived.The report reveals a sequence of events marked by mid-air engine shutdown, cockpit confusion, and failed recovery efforts after a few seconds of takeoff.
Here are the major conclusions from the preliminary investigation report:
- Fuel for both engines cuts mid-hustle: 08:08:39 Just three seconds after the liftoff at UTC,
Fuel cutoff switch Both were triggered to engines, separately separately. “The aircraft achieved a maximum recorded aircraft of 180 not IAS at around 08:08:42 UTC and soon after, the engine 1 and engine 2 fuel cutoff switch was infected with a time interval of 01 seconds after another,” The report stated in the report.
- Cockpit voice recorder pilot catches confusion: Cockpit voice recording reveals confusion in the final moments. “In cockpit voice recording, one of the pilots is heard asking the other why he did the cutoff. The other pilot replied that he did not do so.” Investigators are looking at whether the switch was triggered manually, inadvertently, or by a system malfunction.
- Relite effort on engines: Flight data shows that an automated rebellion was attempted. The engine 1 briefly responded, but the engine 2 did not recover despite several attempts to resume fuel. This failure eventually made it impossible to maintain emphasis for the aircraft.
- Deployment of emergency rats: Ram Air Turbine (RAT), an emergency power source, deployed in response to power failure, active after the takeoff, a clear indicator of the loss of electric power for important systems.
Mayde call First issued moments: 08:09:05 On UTC, one of the pilots released a crisis call: “May Day May.” The air traffic controller attempted to confirm the call sign but no further response was found. Later, the plane crashed.
- Aircraft crashed in nose-up attitude: Flight path analysis suggests that the aircraft hits buildings near the BJ Medical College with 8 degree nasal pitch and level wings. Due to no emphasis from any engine, the aircraft could not maintain flight.
- Thrust Lever found in passive post-cross-cross: Although the thrust liver was in a position of takeoff during the flight, he was found inactive after the accident. Flap and landing gear were confirmed to be in standard takeoff posts, excluding the unusual configuration as a factor.
- The debris is spread over 1,000 feet: The aircraft disintegrated into a wide area, killing several buildings. Wrecks, including engine and landing gear, were scattered over 1,000 feet, reflecting the effect of effect and trajectory.
- Aircraft airwarti, no fuel control issues were previously logged: The aircraft had a valid airworthiness certification. Although some minor categories C and D MEL (minimum equipment list) issues were not related to fuel control. In particular, no previous issue was reported with fuel cutoff switch.
- Alternative Boeing Advisor not followed: While Boeing issued an alternative advice on the fuel control switch locking mechanism, Air India did not check the recommended. The throttle control module of the aircraft was converted to 2019 and 2023.
Next step in investigation
The AAIB report confirms that debris analysis, post mortem reports and component inspections are on. “At this stage of investigation, there is no recommended action for B787-8 and/or GE Genx-1B engine operators and manufacturers,” the agency said.Air India said it is fully cooperating in the investigation. Boeing also said: “We are known as attachment to Aaib to comply with the United Nations International Civil Aviation Organization Protocol, to provide information about AI171.”
