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

Air India's inspection of the locking feature on the fuel control switches of its existing Boeing 787 aircraft found no issues, an internal communication circulated within the airline said.

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.
