Air India is facing fresh turbulence following last week’s fatal crash as additional safety inspections on its Dreamliner fleet have led to flight delays, cancellations and growing passenger anxiety.

The preliminary finding gives investigators a new line of inquiry as they study a crash that killed all but one of the plane’s passengers.

The crash of an Air India Boeing 787 Dreamliner seconds after takeoff from Ahmedabad city, killing all but one of the 242 people on board, is the world's worst aviation disaster in a decade.
