The cockpit voice recorder from last month’s Air India Boeing 787 Dreamliner crash has revealed a crucial exchange between the flight’s two pilots.

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 deadly Air India crash has renewed a decades-old debate in the aviation industry over installing video cameras to monitor airline pilot actions.

The preliminary report into Air India Flight 171 said the fuel was cut off to both engines seconds after liftoff, and cited a 2018 FAA advisory.

Cockpit audio from Air India flight indicates fuel supply may have been cut off by the captain, according to the WSJ. The pilots' body rejected the claim.

International airlines from South Korea and India are preparing to inspect its Boeing fleets following findings from the Air India crash investigation.
