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.

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

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.
