KEY POINTS:
- Both engine fuel control switches moved to “cutoff” position 3 seconds after takeoff, causing catastrophic dual engine failure
- Cockpit recordings show pilots disputed who moved the switches: “Why did you cut off?” “I did not do so”
- 260 people died (241 passengers, 19 on ground); only one survivor escaped through emergency exit
- Boeing stock dropped 4.8% immediately; insurance claims expected to reach $475 million
- First fatal crash of Boeing 787 Dreamliner in its 14-year operational history
The Air India Flight 171 crash that killed 260 people on June 12, 2025, was caused by both engine fuel control switches moving to the “cutoff” position seconds after takeoff, according to a preliminary investigation report released July 12. According to India’s Aircraft Accident Investigation Bureau, the finding raises critical questions about whether the switches were moved intentionally, accidentally, or due to mechanical failure in what became the first fatal crash of a Boeing 787 Dreamliner, as reported by multiple sources including NPR, CNN, and The Air Current.
According to the investigation report cited by NPR and CNN, both fuel control switches moved from “RUN” to “CUTOFF” within one second of each other, just three seconds after the London-bound aircraft reached its maximum takeoff speed of 180 knots. As reported by The Air Current, the switches, located between the pilots’ seats and protected by metal guards designed to prevent accidental movement, require deliberate lifting and shifting to activate. According to multiple sources including Al Jazeera and CNN, cockpit voice recordings captured one pilot asking “Why did you cut off?” with the other responding “I did not do so,” adding to the mystery surrounding the catastrophic failure.
The Boeing 787-8 Dreamliner, operating as AI171 from Ahmedabad to London Gatwick, crashed into the B.J. Medical College hostel complex approximately 32 seconds after takeoff at 1:39 p.m. local time, according to Wikipedia and CBS News. Of the 242 people aboard—including 169 Indian nationals, 53 British citizens, seven Portuguese nationals, and one Canadian—only British passenger Vishwash Kumar Ramesh survived, as reported by CNN, NPR, and People. According to CNN and CBS News, the 40-year-old Leicester resident, seated in the emergency exit row 11A, escaped through an opening created when the emergency door broke upon impact. The crash also killed 19 people on the ground and injured 67 others, primarily medical students in the hostel, according to multiple sources.
Investigation Reveals Rapid Sequence of Failures
According to The Air Current and the preliminary report, flight data shows the emergency Ram Air Turbine deployed automatically at 08:08:47 UTC, five seconds after the fuel switches moved to cutoff position. As reported by CNN and NPR, the crew attempted to restore fuel flow, moving Engine 1’s switch back to “RUN” at 08:08:52 and Engine 2’s at 08:08:56. According to Wikipedia and Al Jazeera, Captain Sumeet Sabharwal, with 15,638 flight hours including 8,596 on the 787, transmitted a mayday call at 08:09:05. The aircraft crashed six seconds later, with Engine 1 showing signs of relight recovery but Engine 2 failing to regain thrust in time, according to The Air Current.
As reported by The Air Current, the investigation referenced a 2018 Federal Aviation Administration advisory that warned of potential fuel control switch locking mechanism issues on Boeing aircraft, including the 787. According to the aviation publication, Air India had not conducted mandatory inspections related to this advisory, though investigators have not determined whether this contributed to the accident. The switches’ design includes multiple safeguards: they sit below the throttle levers, are protected by metal bars on the sides, and require a specific pull-up and shift motion to activate, according to multiple sources.
According to Business Today, aviation safety experts expressed bewilderment at the dual engine failure scenario. Former U.S. Navy pilot Steve Scheibner called it “a real head-scratcher,” noting that the audible deployment of the Ram Air Turbine in crash videos provided “compelling evidence of catastrophic dual engine failure,” as reported by Business Today. According to Wikipedia and aviation experts, the RAT, a small propeller that drops from the aircraft’s belly, only deploys when both engines fail or the aircraft loses all electrical and hydraulic power.
Financial Impact Reverberates Through Aviation Industry
According to Investopedia and Yahoo Finance, Boeing stock plummeted 4.8% on June 12, followed by an additional 1.7% decline the next day. As reported by Fortune and Bloomberg, insurance industry estimates project total claims of $475 million, including $125 million for the aircraft hull and engines, $350 million in passenger liability, and additional ground damage claims. According to the Insurance Journal, this represents the largest aviation insurance claim in Indian history, exceeding the country’s entire annual aviation insurance premium.
According to Business Today and Zee News, the Tata Group, Air India’s parent company, announced compensation of ₹1 crore ($120,000) per victim for all 260 fatalities, supplementing the Montreal Convention’s mandatory minimum of approximately $220,000 per passenger. As reported by Bloomberg and the Insurance Journal, aviation insurance premiums are expected to rise 10-30% globally, with Indian brokers predicting the crash will accelerate an already hardening insurance market.
According to Wikipedia and Air India’s official statements, the airline immediately retired flight numbers AI171 and AI172, planning to terminate the Ahmedabad-London Gatwick route by July 31, 2025. As reported by the Associated Press and NPR, the airline ordered enhanced safety inspections across its 34-aircraft Boeing 787 fleet and temporarily reduced widebody international services by 15%. According to CNBC, India’s Directorate General of Civil Aviation mandated additional checks on fuel parameter monitoring, electronic engine control systems, and oil systems for all Indian-registered 787s.
Safety Record and Industry Implications
According to multiple sources including CBS News and Al Jazeera, the crash marked a devastating end to the Boeing 787’s 14-year fatal accident-free record since entering service in 2011. As reported by CNBC and Time, more than 1,100 Dreamliners operate globally, having carried over 875 million passengers. For Air India, according to Wikipedia and Encyclopedia Britannica, it was the first fatal crash of its mainline operation since the 1985 bombing of Flight 182, though subsidiary Air India Express experienced a fatal accident in 2010.
According to The Washington Post, former National Transportation Safety Board Chair Robert Sumwalt emphasized that preliminary findings indicate “this was not a problem with the airplane or the engines,” focusing attention on human factors or procedural issues. As reported by Simple Flying, the investigation team, including experts from the U.S. NTSB, UK’s Air Accident Investigation Branch, Boeing, and General Electric, faces the complex task of determining whether the fuel cutoff resulted from pilot action, mechanical malfunction, or other factors.
According to The Week and aviation industry sources, the preliminary report’s release addressed criticism about the investigation’s transparency, though some international aviation experts remain concerned about India’s decision to analyze the flight data and cockpit voice recorders domestically rather than at established facilities in France or the United States. The final report, expected by mid-2026, will likely influence global pilot training protocols and potentially aircraft design standards, according to multiple sources.
As reported by The Conversation and aviation safety experts, investigators continue examining why both fuel control switches moved to cutoff position—an action pilots would never intentionally perform during takeoff. According to CNN and People, the extraordinary survival of Vishwash Kumar Ramesh, who told reporters “I don’t know how I managed to escape” while watching other passengers die, serves as a stark reminder of both the fragility and resilience inherent in modern aviation.
