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

(Reuters) – India on Monday ordered its airlines to examine fuel switches on several Boeing models, while South Korea said it would order a similar measure, as scrutiny intensified of fuel switch locks at the centre of an investigation into a deadly Air India crash involving a Boeing 787.

The FAA endorsed this assessment, issuing a Continued Airworthiness Notification stating the fuel control switch design doesn't pose an unsafe condition warranting action on any Boeing model.
