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

The investigation report says Air India did not carry out those inspections - prompting speculation that the accident could have been caused by faulty switches being flipped by accident. However, in an internal note seen by the BBC, the FAA has since reiterated its belief that the issue did not compromise safety.

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.

Aviation experts are calling the sudden engine fuel cutoff on an Air India jetliner “absolutely bizarre.” A preliminary report into the crash that killed at least 260 people does not clarify how the fuel control switches were turned off.

The ICPA says any suggestion of pilot suicide without evidence is a "disservice" to the dignity of the profession.
