India's aviation regulator has ordered the country's airlines to inspect fuel control switches in Boeing aeroplanes, after their reported involvement in a fatal Air India crash that killed 260 people in June.

The U.S. Federal Aviation Administration and Boeing have privately issued notifications that the fuel switch locks on Boeing planes are safe.

The Federal Aviation Administration (FAA), back in 2018, had flagged the potential disengagement of the fuel control switch locking feature on certain models of Boeing aircraft, including 787s and 737s.
