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

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.

Indian investigators cited a 2018 FAA advisory that had warned Boeing operators to inspect the locking mechanism of fuel cutoff switches to prevent unintentional movement. However, the FAA had not mandated any action.
