The National Transportation Safety Board says it'll study the battery certification process for the Dreamliner. On Jan. 7, United Airlines reported a problem with the wiring in one of its Dreamliners, the same area as the battery fire.
But, the NTSB says it believes it's found the culprit. "We believe the evidence points to a single cell as initiating the event" says NTSB Chairman Deborah Hersman. The FAA says this is the first time its grounded an airliner type since 1979.
Five of the systems inside the Dreamliner are manufactured at UTC Aerospace here in Rockford.
