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.

Air India says precautionary inspections have found no issues on the locking mechanism of fuel control switches for select Boeing aircrafts.

Boeing and the Federal Aviation Administration issues a notification that 787 fuel switches are safe after India's preliminary crash report published.
