A cockpit recording of dialogue between the two pilots of the Air India flight that crashed last month supports the view that the captain cut the flow of fuel to the plane's engines, said a source briefed on U.

Air India CEO Campbell Wilson has said the preliminary report into the crash of the London-bound plane found no mechanical or maintenance issues with the aircraft and its engines. In an internal memo to airline staff, Mr Wilson said the report stated all mandatory maintenance tasks of the aircraft had been completed.

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.
