The head of the Federal Aviation Administration said on Thursday the fatal crash last month of an Air India Boeing 787 jet does not appear to have been caused by a mechanical issue or inadvertent movement of the fuel control unit or switches.

The United States Federal Aviation Administration (FAA) has said that investigators have found no evidence of mechanical failure in the fuel control system of the Air India Boeing 787 Dreamliner that crashed in Ahmedabad last month,

The two engines on the Air India flight shut down within one second of each other before the Boeing 787 Dreamliner crashed last month in Ahmedabad, India, killing at least 260 people, according to a preliminary report released Friday.
