The investigation of the crashed Air India Dreamliner in Ahmedabad city last month is "far from over", the airline's Chief Executive Campbell Wilson said in an internal memo on Monday, adding that the airline remains open to further inquiries and cautioned against "premature conclusions".

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

Preliminary findings into last month’s Air India plane crash suggest the aircraft’s fuel control switches were turned off, causing a loss of engine thrust shortly after takeoff.
