FAA Administrator Bryan Bedford said Thursday that the June crash of an Air India flight does not appear to have been caused by a mechanical problem.

The new leader of the US Federal Aviation Administration said the deadly crash of an Air India Boeing Co. 787 jet last month was unlikely to have been caused by a mechanical issue with the plane or inadvertent movement of the aircraft’s fuel control switches.

A preliminary report from India's Aircraft Accident Investigation Bureau earlier this month found the switches had almost simultaneously flipped from "run" to "cutoff" shortly after takeoff.
