A preliminary investigation into the crash of Air India Flight AI-171 has revealed a devastating mechanical failure. The pilot’s seat reportedly slid backward during takeoff due to a faulty locking mechanism, causing the captain to unintentionally pull the throttle into idle. This sudden loss of thrust occurred just seconds after liftoff.

The co-pilot attempted to recover control, but the captain’s compromised position made it nearly impossible. As a result, the Boeing 787 lost lift and crashed into a nearby building. Tragically, 270 people lost their lives, including passengers, crew, and civilians on the ground. A British passenger miraculously survived, while over 40 others sustained injuries.

Investigators highlighted a critical design flaw in the aircraft’s throttle system, noting the absence of emergency override features. They also found that essential emergency protocols were not executed in time.

In response to the findings, both the FAA and EASA have mandated immediate inspections of pilot seat locking mechanisms across all Boeing 787 aircraft. Air India has grounded 12 planes for evaluation.

Boeing has committed to a full seat redesign, with new safety features expected by 2026. Meanwhile, aviation regulators and airlines worldwide are reviewing cockpit safety procedures to prevent future incidents.

Authorities have called the crash a “preventable tragedy,” stressing the urgent need for systemic changes in design and maintenance standards. The final investigation report is due in July 2025.

This heartbreaking event serves as a stark reminder of the vital role safety systems play in modern aviation—and the lives that depend on them.
