U.S. investigators propose review of flight controls after Asiana crash

WASHINGTON (Reuters) - U.S. investigators on Tuesday said Boeing Co should consider modifying flight controls on the 777 jetliner in response to an Asiana Airlines crash in San Francisco last July that killed three people and injured more than 180.

The National Transportation Safety Board accepted 30 findings following an 11-month investigation into the July 6, 2013 crash, and made more than two dozen recommendations to the Federal Aviation Administration, the Seoul-based airline, Boeing, firefighters and San Francisco city and county.
