NEW DELHI: The Aircraft Accident Investigation Bureau (AAIB) has launched its preliminary report into the Air India aircraft crash that killed 260 folks in Ahmedabad on June 12.The 15-web page report, printed late Friday, outlines the preliminary findings and standing of the investigation into the crash of Air India Flight AI171, a Boeing 787-8 Dreamliner headed for London Gatwick. The plane went down shortly after take-off, crashing right into a medical hostel complicated close to the airport. Of the 241 folks onboard, just one passenger survived.This was the primary deadly crash involving a Boeing 787 Dreamliner, marking a big and tragic milestone for the huge-physique plane.A standing report on the crash was earlier launched by the civil aviation ministry on June 26.Here are 10 key findings from the preliminary probe report:
- Fuel provide to each engines was reduce off mid-air: Just three seconds after takeoff, each engines’ fuel management switches transitioned from RUN to CUTOFF inside one second of one another, resulting in sudden lack of thrust.
- Pilot confusion in cockpit: One pilot is heard asking “Why did you cutoff?” to which the opposite replied, “I did not do so,” suggesting a possible technical malfunction or inadvertent activation.
- Relight try failed on one engine: The flight information reveals relight was mechanically tried and succeeded for Engine 1, however Engine 2 didn’t get well regardless of a number of fuel reintroductions.
- RAT deployed instantly: The Ram Air Turbine (RAT), an emergency energy supply, deployed proper after liftoff, indicating a complete lack of energy to important techniques.
- Mayday name issued seconds earlier than crash: At 08:09:05 UTC, a misery name was made, simply seconds earlier than the plane impacted buildings outdoors the airport perimeter.
- Aircraft crashed nostril-up however with engines off: Analysis reveals the aircraft hit buildings with an 8° nostril-up angle and degree wings, however with each engines inactive, unable to maintain climb.
- Cockpit controls in regular takeoff mode: Flap and touchdown gear levers have been in customary takeoff positions; thrust levers have been present in idle post-crash, although they have been at takeoff thrust throughout flight — confirming an in-flight cutoff.
- Debris and wreckage strewn over 1,000 ft: The plane hit a number of buildings and constructions, with parts like engines, wings, and touchdown gears scattered throughout a large crash zone close to BJ Medical College hostel.
- Aircraft was airworthy with minor MEL points: The plane had legitimate airworthiness certificates and some Category C and D MELs (non-vital upkeep points), none linked to fuel management.
- No prior points reported with fuel management switches: While Boeing had issued an advisory (not obligatory) on fuel management swap lock considerations, Air India had not performed the elective inspections. The plane had earlier throttle module replacements in 2019 and 2023.
The investigation is ongoing. Fuel pattern testing, put up-mortem experiences, and additional forensic evaluation will form the ultimate findings. The AAIB has not issued security suggestions but, however the occasion raises severe considerations about potential technical faults or unintended actions associated to fuel cutoff techniques.
