Air India CEO confirms all Boeing 787 aircraft checked post-crash, no mechanical issues found, urges against premature conclusions.

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".

A preliminary assessment in last month’s disaster focusing on fuel being cut to both engines only deepened the mystery for people grieving loved ones.
