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 Federation of Indian Pilots said that the report lacks comprehensive data and relies on cockpit recordings, “suggesting pilot error” and “questioning the professional competence” of the crew

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.
