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

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.

Just weeks before the deadly crash of an Air India Boeing 787-8 in Ahmedabad, the UK’s Civil Aviation Authority (CAA) had warned of potential fuel control problems in several Boeing aircraft models, including the 787 Dreamliner.
