A cockpit recording of dialogue between the two pilots of the Air India flight that crashed last month supports the view that the captain cut the flow of fuel to the plane's engines, said a source briefed on U.

FAA Administrator Bryan Bedford said Thursday that the June crash of an Air India flight that killed 260 people does not appear to have been caused by a mechanical problem with the aircraft's fuel control switches, which have emerged as a major focus in the Indian government's investigation into the disaster.

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