Boeing has completed 85% of certification test points for regulatory approval of the Rolls-Royce Trent 1000-powered 787.
Scott Fancher, 787 programme vice president and general manager says the airframer is still aiming to deliver the first 787 to Japan's All Nippon Airways in the third quarter
Boeing says the General Electric GEnx-1B-powered 787 is "just over 65%" through it's certification test points.
Fancher's comments came at the opening of the company's San Antonio, Texas 787 change incorporation facility, which is now hosting Airplane 23, likely the first of the long-range twins for Japan Airlines.
San Antonio will host at least six aircraft, including three test aircraft, through 2013.
Additionally, Fancher says extended twin operations testing (ETOPS) and system functionality and reliability (F&R) evaluations are expected to begin in the "next couple of months" and will be among the final certification tasks for the programme.
The airframer initially planned to deliver the first 787 to ANA in May 2008, but the programme has been beset by years of delays stemming from design changes and issues with its global supply chain.
