U.S. regulators approved on Friday a revamped battery system for Boeing Co’s 787 Dreamliner，a crucial step in returning the high-tech jet to service after it was grounded in January because its lithium-ion batteries overheated.
美國監管部門19日批準了波音公司787“夢想”客機電池系統的改進方案。這將是1月份以來因鋰離子電池過熱而被禁飛的該型高科技客機重新恢復運營的關鍵一步。(路透社)
The Federal Aviation Administration (FAA) approval of design changes allows Boeing to immediately begin making repairs to the fleet of 50 planes owned by airlines around the world.
此次美國聯邦航空管理局批準的設計變更方案，將允許波音公司立即對由全球多家航空公司擁有的停飛中的50架客機進行修理。(路透社)
Planes now need to be fitted with a “containment and venting”system for both the lithium-ion batteries. That includes a stainless-steel enclosure to prevent heat，fumes or fire from spreading if a battery overheats in flight，said the FAA.
據聯邦航空管理局稱，改進后的飛機需要為鋰離子電池組安裝包括不銹鋼外殼的“隔離和通風”系統，如若在飛行途中某一電池過熱，能防止熱量、煙霧、火勢的擴散。(英國廣播公司)
FAA administrator Michael Huerta said：“A team of FAA certification specialists observed rigorous tests we required Boeing to perform and devoted weeks to reviewing detailed analysis of the design changes to reach this decision.”
聯邦航空管理局官員邁克爾·維爾塔表示，該機構一個認證專家小組對波音進行的嚴格測試予以監督，并花費數周時間對設計變更方案進行詳細分析，最終才確定該項決定。(《衛報》)
Jim McNerney，Boeing’s chief executive，said the FAA’s decision “clears the way for us and the airlines to begin the process of returning the 787 to flight with continued confidence in the safety and reliability of this game-changing new airplane”.
波音公司首席執行官吉姆·麥克納尼稱，聯邦航空局的決定“為我們以及其他航空公司準備787客機的復航掃清了道路，并使大家對這款改進后的新型飛機的安全性和可靠性充滿信心。”(《金融時報》)
FAA said airlines needed to replace the batteries to return to service. It said it will publish a final directive next week. Other international regulators are likely to follow but it will still be a couple of weeks before flights resume.
聯邦航空管理局表示，航空公司須先更換787客機的電池方能恢復運營，并稱4月22日-28日當周將發布最終指示。其他國際監管機構可能采取相同措施，但距離復航仍將有數周時間。(英國廣播公司)
All of the 50 Boeing 787 planes in service were grounded in mid-January after their lithium-ion batteries emitted smoke on several separate occasions.
今年1月中旬，全球50架投入運營的波音787客機因數起鋰離子電池過熱冒煙事件而遭全部禁飛。(英國廣播公司)
