Boeing probe focuses on battery, more checks due
TAKAMATSU, Japan (REUTERS) - United States (US) and Japanese aviation safety officials wrapped up their initial investigation of a badly damaged battery from a Boeing Co 787 Dreamliner jet on Friday, saying further checks would be held in Tokyo and could take a week to complete.
But the top US transportation official, Ray LaHood, said the 787 would not fly until regulators were "1,000 per cent sure" it was safe - a week after having said he would not hesitate to travel on a Dreamliner.
Officials from the Federal Aviation Administration (FAA), US National Transportation Safety Board (NTSB) and Boeing joined Japanese authorities looking into what caused warning lights to go off on an All Nippon Airways Co domestic flight earlier this week, prompting the aircraft to make an emergency landing at Takamatsu airport in western Japan.
The incident prompted regulators in the United States and around the world to ground the 50 Dreamliners in service.
