US aerospace giant Boeing said late Friday it had suspended deliveries of its new 787 Dreamliner jet until a battery problem is resolved, but continues to build the plane. “We will not deliver 787s until the FAA approves a means of compliance with their recent Airworthiness Directive concerning batteries and the approved approach has been implemented,” a Boeing spokesman said in an email. “Production of 787s continues,” he said. The Federal Aviation Administration on Wednesday ordered the grounding of US-operated 787s to address the battery problem after a damaged battery on an All Nippon Airways 787 forced an emergency landing. The risk of fire from overheating powerpacks has emerged as a major concern for Boeing’s cutting-edge new planes since the incident on the domestic flight in Japan, prompting airlines around the world to ground all 50 of the 787s in service.
