The transport ministry said Friday it will dispatch two ministry officials to the United States from Sunday as part of the investigation into a mishap involving Boeing Co. 787 Dreamliner operated by All Nippon Airways Co.
The pair, electrical systems specialists, are expected to meet with engineers of Boeing in Seattle to gather information and meet with officials of the U.S. Federal Aviation Administration, the ministry said.
The Ministry of Land, Infrastructure, Transport and Tourism also said it has decided to double the number of members engaged in its investigation to 16.
Meanwhile, the government-affiliated Japan Transport Safety Board will send an inspector Friday to the United States to conduct a probe into a battery charger made by a manufacturer based in Arizona.
The charger was installed in the ANA Dreamliner that made an emergency landing on Jan. 16 at Takamatsu Airport in Kagawa Prefecture after a battery-related problem caused smoke in the cockpit.
