<h1>Fuel control switch inspection directive led airlines to complete checks of Boeing 787 and 737 locking systems, finding no issues.</h1> A safety directive required inspection of the fuel control switch locking mechanism on Boeing 787 and 737 aircraft after a preliminary investigation reported fuel supply to both engines was cut off; Air India and its affiliate completed inspections within the prescribed timeframe and reported no issues. The preliminary report referenced cockpit voice recordings and an FAA Special Airworthiness Information Bulletin that noted potential disengagement of the locking feature but was not an airworthiness directive.
