The US Federal Aviation Administration (FAA) on Friday April 19th, 2013 approved Boeing’s plans to improvements to the 787 Dreamliner battery systems. The FAA approval allows Boeing and airlines to install the approved modifications to return to service.
The improved battery system includes design changes to both prevent and isolate a fault should it occur. The new steel enclosure system is designed to keep any level of battery overheating from affecting the airplane.
Ethiopian Airlines plans to resume flying its Boeing 787 Dreamliners in the last week of April or the first week of May 2013.
