A preliminary investigation into the crash of Air India Flight AI-171 has revealed a devastating mechanical failure during takeoff. The captain’s seat slid backward unexpectedly due to a faulty locking mechanism, causing the pilot to unintentionally pull the throttle into idle. This sudden reduction in engine thrust occurred just seconds after liftoff. The co-pilot tried to regain control but was obstructed by the captain’s position. As a result, the Boeing 787 lost lift and crashed into a nearby building, killing 270 people, including passengers, crew, and civilians. A British passenger survived, while over 40 others were injured.

Investigators also highlighted critical safety oversights, including the absence of emergency throttle override systems in the 787’s design. In response, the FAA and EASA have mandated immediate seat mechanism inspections across airlines. Air India has grounded 12 aircraft from its fleet, and Boeing has committed to redesigning the pilot seat system by 2026. The crash, described by authorities as “entirely preventable,” has triggered calls for sweeping aviation safety reforms. The final investigative report is expected in July 2025.
