Air India Crash Investigation: Shocking Fuel Switch Discovery Reveals 5 Critical Findings
The Air India crash investigation has uncovered disturbing new details about the tragic June 12, 2025 accident that claimed 260 lives in Ahmedabad. The Aircraft Accident Investigation Bureau (AAIB) released a preliminary report that reveals both engines’ fuel cutoff switches mysteriously moved to the “CUTOFF” position shortly after takeoff, raising serious questions about what caused this catastrophic aviation disaster.
Air India Flight 171, a Boeing 787-8 Dreamliner bound for London Gatwick, crashed just 30 seconds after takeoff from Ahmedabad Airport. The aircraft plummeted into a hostel block at B.J. Medical College, killing 241 passengers and crew members on board, plus 19 people on the ground. Only one passenger survived this devastating crash.

What the Air India Crash Investigation Has Revealed
The preliminary findings from the Air India crash investigation paint a troubling picture of the aircraft’s final moments. According to the 15-page report released by India’s Aircraft Accident Investigation Bureau, flight data recorders show that both engines lost thrust after their fuel control switches moved from the “RUN” to “CUTOFF” position within one second of each other.
The aircraft had reached an airspeed of 180 knots when both engines’ fuel cutoff switches were “transitioned from RUN to CUTOFF position one after another with a time gap of 01 sec,” according to the report. This critical finding suggests that the fuel supply to both engines was deliberately or accidentally cut off, causing immediate engine shutdown and complete loss of thrust.
Cockpit Voice Recordings Reveal Pilot Confusion
Perhaps most disturbing are the cockpit voice recordings recovered from the wreckage. In the cockpit voice recording, one of the pilots is heard asking the other “why did he cutoff,” the report says, indicating that at least one pilot was unaware of why the fuel switches had moved to the cutoff position.
This audio evidence suggests that the fuel cutoff may not have been an intentional action by the flight crew, raising questions about whether the switches moved due to mechanical failure, inadvertent activation, or some other unknown cause.
The Boeing 787 Dreamliner’s First Fatal Accident
This Air India crash investigation marks a tragic milestone in aviation history, as it represents the first fatal accident involving a Boeing 787 Dreamliner since the aircraft entered service in 2011. The Boeing 787-8 involved in the crash was relatively new and had been operating normally before the incident.
The aircraft was carrying 242 people total – 229 passengers and 13 crew members – when it departed Ahmedabad at 13:39 IST on June 12, 2025. The plane was bound for London Gatwick Airport on what should have been a routine international flight.
Technical Analysis of Fuel Control Switch Failure
Aviation experts analyzing the Air India crash investigation findings explain that fuel control switches are critical safety components on commercial aircraft. Moving a fuel control switch from RUN to CUTOFF in flight would cause the fuel supply to stop flowing to the associated engine, resulting in its immediate shutdown and the loss of any thrust.
The switches also control electrical power generation, as stopping the two electrical generators on each engine from providing power to many of the aircraft systems. This means the fuel cutoff would have created a cascading series of system failures, leaving the pilots with very limited options and virtually no time to react.
Understanding the Timeline
The Air India crash investigation timeline reveals just how quickly events unfolded:
- Takeoff: Flight 171 departed Ahmedabad Airport at 13:39 IST
- Climb: Aircraft reached 180 knots airspeed during initial climb
- Fuel Cutoff: Both engines’ fuel switches moved to cutoff position within 1 second
- Pilot Response: Cockpit voice recorder captures pilot confusion about the cutoff
- Crash: Aircraft impacted hostel building approximately 30 seconds after takeoff
This compressed timeline highlights the challenge pilots faced in responding to such a catastrophic system failure during the most critical phase of flight.
International Cooperation in Investigation
The Air India crash investigation involves multiple international partners working together to determine the cause of this tragedy. Experts from India’s Aircraft Accident Investigation Bureau are probing the crash with assistance from the U.K., the U.S. and officials from various aviation authorities.
