Boeing Co. is stopping deliveries of the 787 until the plane's electrical system is fixed.
Boeing says production is not stopping. The plane is assembled in Everett, Wash., and North Charleston, S.C. out of pieces built all over the world.
The Federal Aviation Administration has grounded the 787s currently in use until Boeing can prove the batteries are safe.
The FAA's emergency airworthiness directive issued late Wednesday said the 787's battery system would need to be modified, "or other actions" taken, under a method approved by the FAA. However, the agency has not said what those actions should be.
Boeing said deliveries are stopped until an FAA-approved fix has been carried out. The FAA has said it is working on a fix but it has not said how long it will take.
Boeing's move is not surprising. Many experts had suspected that airlines would not accept new 787s from the company until the FAA directive was carried out.
