Japan's transport minster, Akihiro Ohta, announced today that the country's airliners can resume flying grounded Boeing 787 Dreamliners once a newly approved battery system is installed. "We have reached a conclusion that there is no problem with the judgment by the FAA," Ohta told the Associated Press. Back in January two separate fires caused by the 787's lithium ion batteries led to the FAA temporarily grounding all Dreamliners. Japan's decision comes shortly after Boeing's CEO, Jim McNerney, stated during the company's recent fiscal conference call that he expected all 50 aircraft to be fixed by the middle of May. Japanese airline officials are forecasting a slightly longer timeline, with the country's 787s returning to the skies around June and test flights scheduled to begin on April 28th.
