00:00Just four weeks before the June 12th tragedy, the UK Civil Aviation Authority had flagged
00:04the fuel shut-off valve on several Boeing aircraft models, including the 787 Dreamliner
00:08that crashed.
00:09The May 15, 2025 safety notice from the UKCAA followed a US Federal Aviation Administration
00:15Airworthiness Directive from 2015.
00:17The directive flagged fuel shut-off valve actuators as a potential safety concern in
00:20five Boeing aircraft models, 737, 757, 767, 777 and the 787.
00:27A fuel shut-off valve is a safety device that stops the flow of fuel to the engine.
00:30This is typically done during maintenance, in case of an engine fire or during forced landings.
00:35The UK regulator directed airline operators to test, inspect or replace fuel shut-off valve
00:39actuators on Boeing 787s among others.
00:42In 2018, the USFAA had also issued a Special Airworthiness Information Bulletin warning that
00:47some Boeing 737 aircraft had fuel control switches installed without the locking feature engaged,
00:52a design also used in the 787 Dreamliners.
00:55However, the AAIB preliminary report found that Air India didn't inspect the locking mechanism
00:59of the fuel cut-off switches recommended by the 2018 FAA advisory as it was not mandatory.
