Domestic Indian airlines were ordered to carry out inspections of fuel switches on Boeing aircraft in their fleets by the country's aviation regulator in the wake of last month's deadly Air India crash.

The preliminary report into Air India Flight 171 said the fuel was cut off to both engines seconds after liftoff, and cited a 2018 FAA advisory.

The report and India’s inspection order referred to an advisory from the Federal Aviation Administration in 2018 that recommended that carriers using Boeing models, including the 787, inspect the locking mechanism of the fuel control switches to ensure they could not be moved accidentally.
