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.

FAA and Boeing said fuel switch locks on aircraft are safe, despite initial reports that fuel supply was cut off in recent Air India crash.

SEOUL: South Korea is preparing to order all airlines in the country that operate Boeing jets to examine fuel switches in the focus of an investigation of a deadly Air India crash that killed 260 people.
