A preliminary investigation into the tragic crash of Air India flight AI171 has revealed that a disruption in the aircraft’s fuel supply system led to the catastrophe, claiming 260 lives. The Boeing 787 Dreamliner, en route from Ahmedabad to London, lost power shortly after takeoff when the fuel cutoff switches in the cockpit were manually flipped from the RUN to the CUTOFF position, starving the engines of fuel. The aircraft, which had just reached a speed of 180 knots, began to lose altitude rapidly and crashed within moments, resulting in the deaths of all but one passenger aboard. Crucially, investigators recovered cockpit voice recordings and flight data indicating that the pilots were unaware of the switch movement, with one audibly questioning the other during the final seconds.
The Indian Aircraft Accident Investigation Bureau (AAIB) has confirmed that both engines were attempting to restart just seconds before impact, but the process was too late to prevent disaster. According to the report, emergency systems like the Ram Air Turbine were deployed, and engine relight sequences had initiated, but the aircraft was unable to maintain lift. Airport footage and black box recordings highlight the confusion and urgency in the cockpit, including a distress call of “MAYDAY” before the plane crashed into a building housing a hostel associated with BJ Medical College, killing numerous people on the ground. The report also confirmed no external issues like bird strikes, dangerous cargo, or engine defects were involved; both engines had been recently installed and were functioning normally.
Experts point to the fuel cutoff switches’ design — positioned between the pilots and equipped with safety mechanisms — and suggest that it’s extraordinarily rare for such switches to be accidentally triggered. Safety analyst David Soucie emphasized that these controls are not automated and require deliberate action to operate. The captain of the doomed flight had more than 15,000 hours of flying experience, and the co-pilot had logged over 3,400 hours. The report has prompted widespread scrutiny of cockpit protocols and system safeguards. Air India, acknowledging receipt of the preliminary findings, has pledged full cooperation and expressed its solidarity with the victims’ families, stating that it remains committed to transparency and support throughout the investigation process.
