B787 flights resume

Boeing 787 (Dreamliner) planes are beginning to fly again as airlines upgrade the lithium battery systems; batteries in some planes had overheated (March ’13, pg. 19). Ethiopian Airlines, on April 26, was the first to fly a commercial Dreamliner with the new system. Other airlines are expected to resume 787 service over the next few months.

In addition to replacing components of batteries and chargers, the upgraded systems include new containment and venting systems around the batteries. For 787s owned by Japan Airlines (JAL) and All Nippon Airways (ANA), the Japan transportation ministry is also requiring battery-monitoring systems and an ongoing inspection program.
