The black box has revealed the cause of the fatal crash of the Air India Boeing 787, with the final moments captured in detail.

A preliminary report into the devastating crash of Air India Flight AI-171 has uncovered a chilling and preventable cause: a mechanical failure in the pilot’s seat that ultimately cost 270 lives.

Critical error: Pilot seat malfunction during take-of

According to the official report, the disaster unfolded during takeoff when the locking mechanism of the pilot’s seat failed, causing the seat to suddenly slide backwards.

In a tragic reflex, the captain’s hands pulled the throttle levers into the ‘idle’ position, drastically reducing the engine thrust just seconds after liftoff.

The co-pilot immediately attempted to regain control, but the captain’s reclined position obstructed access to vital flight controls.

Within seconds, the Boeing 787 lost lift and crashed into a nearby building housing medical workers.

Black box timeline: A catastrophe in seconds. Flight data and cockpit voice recordings provided a sobering sequence of events:

+12 seconds – Captain’s seat slides backwards

+15 seconds – Co-pilot exclaims: ‘We’re losing thrust’!

+26 seconds – Aircraft enters stall at just 214 feet altitude

Despite attempts at recovery, the aircraft’s proximity to the ground and the blocked controls proved fatal.

Lack of emergency protocol and system safeguards

Investigators also noted a critical absence of emergency commands such as ‘GO-AROUND’ or ‘STAB TRIM’, standards in such situations.

Additionally, the 787’s thrust levers lack safety systems like weight-based lockout or reverse-motion protection, exacerbating the crisis.

The report has triggered immediate global scrutiny with the U.S. Federal Aviation Administration (FAA) and European Union Aviation Safety Agency (EASA) ordering urgent inspections of all Boeing 787 pilot seats.

Air India grounded 12 aircraft with similar maintenance histories.

Boeing has pledged a full redesign of the seat mechanism, with updates expected by 2026.

The final death toll stands at 270, including passengers, crew, and individuals in the hostel struck by the aircraft. The only survivor is a British national, currently receiving treatment.

The flight had 242 onboard:

*169 Indian nationals

*53 British nationals

*7 Portuguese nationals

*1 Canadian national

Over 40 people on the ground were also injured.

Final report is due in July 2025 as full investigation report is expected in July 2025, but authorities have already vowed to reform inspection protocols and reinforce flight safety standards globally.
