Boeing’s Final 787 Test Sets Stage for FAA Battery Review

Boeing Co.’s completion of a final test flight for its 787 Dreamliner sets the stage for a regulatory review of battery upgrades that will determine whether the grounded jet can re-enter commercial service.

“The purpose of the flight was to demonstrate that the new battery system performs as intended during normal and non-normal flight conditions,” Chicago-based Boeing said in a statement yesterday. The planemaker said it will analyze flight data and submit the required materials to the U.S. Federal Aviation Administration “in the coming days.”
