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.

The sudden movement of engine fuel switches has taken centre stage in the investigation of the Air India Boeing Dreamliner crash that killed 260 people in June, the world's worst aviation disaster in a decade.

NEW DELHI — A cockpit voice recording from the June 12 crash of an Air India Boeing 787 indicates that one of the pilots may have cut off fuel to the plane’s engines just after takeoff, according to a report by The Wall Street Journal, citing people familiar with the early findings of U.S. investigators.
