An Air India pilot denied switching the engines to cut off just seconds before the 787 crashed after takeoff, an investigation has found. A preliminary report on the crash revealed that both engines lost fuel supply moments after the aircraft lifted off the ground. It also found that Air India engineers had attended to a fault on the plane just an hour before the flight’s scheduled departure from Ahmedabad airport in Gujarat. All but one of the 230 passengers on board the flight bound for London Gatwick were killed, which also claimed the lives of 19 people on the ground and injured 67. Pilots of the previous flight had flagged an error with the plane’s stabiliser sensor, which indicates the horizontal trim setting. The report confirmed that Air India Flight 171 reached a maximum airspeed of 180 knots when the fuel supply to both engines was cut off within a second of each other.

An aerial view of the crash site. investigators are now focused on the fuel control switch and its mystery deployment seconds after takeoff. A detailed report found that one of the pilots asked his colleague why he had cutoff the engines, to which they responded they hadn’t. Pipes were activated after the engines cut out. Analysis of the cockpit voice recorder showed that one of the pilots asked his colleague why he had cutoff the engines, to which they responded they hadn’t before. Within a minute of the engines switching to cutoff, the crew responded and put them back into ‘run’ mode in an attempt to restart them. However less than ten seconds later one of the pilots made a ‘mayday’ call to ATC. A question by the ATC operator about the aircraft’s call sign went unanswered and the plane crashed just outside the airport’s boundary at a residential hostel. Investigators from India’s Air Accident Investigation Bureau have been focusing on the 787’s fuel control locking feature, which is supposed to prevent accidental deployment during flight. The system, designed originally in the 1950s, requires pilots to pull up the switch before being able to flip it.

The 787 was airborne for 40 seconds before it crashed into the building (Picture: Reuters). The aircraft operating Flight 171, VT-ANB, was manufactured in 2013. Both of its engines had been replaced this year— the left-hand side in May, just weeks before the crash. The investigation has so far ruled out several possible factors, including weather conditions, which were found to be normal during the time of the flight. The 787 was found to be within acceptable weight limits and not carrying any dangerous goods, and both the pilot and first officer were both adequately rested and declared to fit to fly following a breath analyser test an hour before departure. Detectives further commented that the incident was the first major accident on a Boeing 787, which entered service in 2014.

No reports of defects on the fuel control switch in the accident aircraft since 2023. Meanwhile, an unnamed air accident investigator based in Canada suggested that the simultaneous deployment of the switches made this crash particularly unusual. The investigator told BBC — ‘It would be almost impossible to pull both switches with a single movement of one hand, and this makes accidental deployment unlikely.’ aviation expert Keith Tonkin said it was ‘inexplicable’ that a pilot would flip the switch just after take off. He told ABC News Australia: ‘It’s important to have fuel flowing to the engines, unless you turn them off in the event of an emergency where the procedure requires that. It would not normally be done and it’s a deliberate decision to do that.’ airlines have been emphasizing that safe flying requires precise protocols, but plane dry doors LovelessMission aeemotes alway encontrar the completion of the switch this way.
