why did air india flight crash

The Air India flight crash occurred because both engines lost power shortly after takeoff due to the fuel control switches being moved from the "RUN" to the "CUTOFF" position, which cut off the fuel supply to the engines. This caused an immediate loss of thrust, leading the aircraft to crash into a residential area near Ahmedabad. The cockpit voice recorder revealed a tense exchange where one pilot asked why the fuel was cut off, and the other denied doing it, but it remains unclear who actually moved the switches. Despite attempts to restart the engines by reversing the switches quickly, the aircraft did not regain enough power to avoid crashing. The investigation showed that the aircraft was considered airworthy and had recent maintenance. A 2018 safety advisory warned of a possible defect in the fuel control switch system in some Boeing aircraft, including the Dreamliner, but Air India had not inspected this system since it was not mandatory. The crash remains under investigation, but the key fact is that the fuel cutoff led to both engines failing almost simultaneously, which caused the fatal crash that killed all passengers and many people on the ground except one survivor.
