U.S. aviation officials say a review of the Boeing 787 Dreamliner has found the plane's design is safe, despite the battery-related problems the aircraft has experienced since its rollout.
A joint report
released Wednesday by Boeing and the Federal Aviation Administration said the plane was "soundly designed." The report makes seven recommendations for further improvements by Boeing and the FAA.
The review was initiated after a lithium battery fire occurred more than a year ago aboard a Boeing 787 parked at Boston's Logan International Airport.
The worldwide fleet of 50 Dreamliners was grounded for more than three months following that incident.
Boeing later rolled out modifications to the battery, but said it did not know what caused the meltdowns.
Earlier this year, battery problems prompted the grounding of a Boeing 787 at Tokyo's Narita International Airport. An investigation found the battery did not catch fire, and Boeing said the modifications it originally implemented with the Dreamliner worked in that incident.
