"The head of the Federal Aviation Administration said on Thursday the fatal crash last month of Air India flight 171 does not appear to have been caused by a mechanical issue or inadvertent movement of the fuel control unit or switches.
"We can say with a high level of confidence is it doesn't appear to be a mechanical issue with the Boeing fuel control unit," Bryan Bedford, the FAA's administrator, told reporters on the sidelines of an air show in Wisconsin.
The probe into the Air India crash, which killed 241 of the 242 people on board and 19 on the ground, is focused on the fuel control switches of the Boeing 787 jetliner.
Boeing and Air India did not immediately comment."
