Last Friday, the FAA announced a comprehensive review of the 787’s critical systems with the possibility of further action pending new data and information.  In addition to the continuing review of the aircraft’s design, manufacture and assembly, the agency also will validate that 787 batteries and the battery system on the aircraft are in compliance with the special condition the agency issued as part of the aircraft’s certification.
