(Reuters) -A cockpit recording of dialogue between the two pilots of the Air India flight that crashed last month indicates the captain cut the flow of fuel to the Boeing 787 jet's engines, the Wall Street Journal reported on Wednesday.

The deadly Air India crash last month has renewed a decades-old debate in the aviation industry over installing video cameras monitoring airline pilot actions to complement the cockpit voice and flight data recorders already used by accident investigators.

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 Air India airliner carrying 230 passengers and 12 crew members was on its way to the United Kingdom when it crashed into a building shortly after takeoff on June 12, killing all aboard, except for one survivor, and several people on the ground, according to authorities.

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

Although the preliminary report into what caused the loss of Air India Flight 171 last month has provided some answers, it has also prompted a wave of speculation about its cause. The BBC's International Business Correspondent Theo Leggett reports on what we know - and what we don't know - so far.

The CEO of Air India sought to draw a line under rife speculation around the cause of last month's air disaster in Ahmedebad, saying the preliminary investigation had ruled out a mechanical cause for the crash.
