The latest investigation into the June crash of Flight 171 points to potential human error as the key issue surrounding the aircraft's fuel supply cut-off. Authorities are now requiring compliance with prior recommendations regarding fuel switch mechanisms.

In response to the devastating incident involving Air India Flight 171, regulators in India, South Korea, and Singapore have mandated immediate inspections of fuel control switches on Boeing aircraft. The heightened scrutiny follows a preliminary report indicating that the plane’s fuel supply was abruptly cut seconds after takeoff due to the switches being turned off.

While the inquiry does not yet provide definitive conclusions regarding the cause or accountability for the crash, it has ruled out mechanical failures and design flaws, shifting the focus to the fuel switches designed for Boeing’s 787 model. Notably, expertise suggests these switches are not easily activated unintentionally due to their locking mechanisms, thus raising questions about possible human interference.

The FAA had previously recommended examinations of these locking features back in 2018, advising that airlines verify their resilience against accidental adjustments. However, according to investigators, Air India had overlooked these inspections since they were deemed non-mandatory. The report revealed that the FAA had not classified the locking feature’s safety concerns as severe enough to warrant immediate action, complicating oversight efforts.

Responses from airlines such as Singapore Airlines, which has completed its inspections, underscore the industry-wide impact of the findings. As authorities aim to bolster air safety measures, the focus remains on ensuring regulatory compliance and preventing future tragedies in aviation.
