A preliminary investigation into the crash of Air India Flight AI-171 has revealed a mechanical failure as the cause of the tragic accident. During takeoff, the pilot’s seat unexpectedly slid backward due to a defective locking mechanism, which led the captain to unintentionally pull the throttle into idle. This sudden loss of engine thrust occurred just seconds after liftoff. The co-pilot struggled to regain control, obstructed by the captain’s position, and the Boeing 787 quickly lost lift and crashed into a nearby building. The accident claimed the lives of 270 individuals, including passengers, crew, and people on the ground. A British passenger was the sole survivor, while more than 40 others sustained injuries.

Investigators also identified significant lapses, including missing emergency throttle safeguards and inadequate safety features in the aircraft’s design. In response to the findings, aviation authorities like the FAA and EASA mandated immediate inspections of pilot seats across similar aircraft. Air India grounded 12 of its planes, and Boeing has committed to redesigning the affected seat system by 2026. A final report is expected by July 2025, but officials have already promised sweeping safety reforms. The crash has been described as a preventable tragedy that highlights critical flaws in both design and procedure, with a renewed focus now placed on ensuring such an incident can never occur again.
