EVERETT, Wash., 9 March, 2012. Boeing (NYSE: BA) has completed all flight tests expected to be required for type certification of the 787-8 Dreamliner with General Electric GEnx engines. This marks the end of all certification flight testing associated with the baseline model of the 787. Testing on engine and airframe improvements will continue as needed, as it does for all airplane programs. Ground testing to complete certification requirements has also concluded. The final flight concluded late last month with the landing of the 35th 787 built. Flight testing is one of many elements reviewed by the U.S. Federal Aviation Administration before it certifies a new airplane type. Certification of the 787 Dreamliner with Rolls-Royce engines was completed in August 2011. Each new combination of airframe type and engine requires additional certification.
