The preliminary report into the crash referred to a 2018 FAA advisory, which recommended that operators of several Boeing models inspect the locking feature of the fuel-cutoff switches. The report said Air India did not carry out the inspections.

The US Federal Aviation Administration (FAA) has said the fuel control switches in Boeing aeroplanes are safe, following their reported involvement in a fatal Air India crash that killed 260 people in June.

The US Federal Aviation Administration has issued a notice to its international counterparts that fuel control switches in Boeing aeroplanes like the Dreamliner involved in last month’s fatal Air India crash do not pose a safety issue.
