(TOKYO) — The investigation into Boeing’s troubled 787 Dreamliners now spans three countries.
Japan’s transport ministry is investigating a British company that makes the plane’s valve actuators. The National Transportation Safety Board, meanwhile, is inspecting the Arizona-based manufacturer of the jet’s lithium-ion battery chargers.
In Kyoto Tuesday, Federal Aviation Administration and Japanese officials continued their probe of the battery maker for a second day.
The NTSB has ruled out an overcharged battery as the cause of the fire on board a Japan Airlines Dreamliner this month. But the battery remains the focus of a separate investigation into an All Nippon Airways flight that prompted an emergency landing last week.
The conflicting problems have prolonged flight cancellations and grounded dozens of Dreamliners around the world.
