A month after the tragic Air India Dreamliner crash in Ahmedabad that killed over 270 people, a preliminary investigation has revealed a chilling mid-air mystery: the aircraft’s engine fuel switches were inexplicably turned from ‘RUN’ to ‘CUTOFF’ just seconds after takeoff—cutting off fuel to both engines and dooming the flight within moments.
In the final moments captured on the cockpit voice recorder, one of the pilots was heard asking, “Why did you cut off?” to which the other pilot replied, “I didn’t.”
This haunting exchange is now at the centre of India’s worst aviation disaster in decades.
The 15-page report, released Saturday by the Aircraft Accident Investigation Bureau (AAIB), sheds light on a puzzling chain of events aboard the London-bound Air India Boeing 787-8 Dreamliner, which crashed shortly after takeoff on June 12. Data from the Enhanced Airborne Flight Recorders (EAFR) indicates that both engines’ fuel control switches were manually moved to CUTOFF within seconds of each other—an act that immediately terminated fuel supply to the engines.
Startlingly, the switches were then flipped back to RUN, suggesting the pilots tried desperately to recover the aircraft—but it was too late. The voice recorder went silent seconds later. The aircraft was airborne for just 32 seconds.
Shortly after, a panicked MAYDAY call was transmitted by one of the pilots. Air Traffic Control responded, asking for the call sign—but received no answer. Moments later, the aircraft nosedived and exploded outside the airport boundary, crashing into a hostel for medical students. Only one person aboard survived. Nearly 30 people on the ground were also killed.
The report confirms that Captain Sumeet Sabharwal, a highly experienced Line Training Captain with over 8,200 flying hours, was at the controls. He was assisted by First Officer Clive Kundar, who had logged 1,100 hours. Both were certified fit and well-rested.
Investigators found no signs of sabotage but highlighted a known FAA advisory about a potential flaw in fuel control switch installations. A past bulletin warned that switches on some Boeing aircraft may be installed with a disabled locking mechanism—though it was not deemed an "unsafe condition" at the time.
The Ram Air Turbine (RAT), a backup system used in case of dual engine failure, deployed immediately after takeoff, as seen on CCTV footage—confirming total power loss. No bird strike or foreign object interference was observed.
In a chilling parallel, the report recalls a 1980s Delta Air Lines incident in which a pilot accidentally cut off engine fuel—but managed to restart mid-air due to higher altitude. The Air India crew wasn’t so lucky.
The AAIB is expected to conduct deeper forensic analysis into the fuel switch mechanism and crew inputs. Until then, one question echoes louder than ever: “Why did you cut off?”
