摘要

Boeing is designing a lower-weight production version of the wing root reinforcement that delayed first flight of the 787 by almost six months, and it is working on the first aircraft to arrive on the production line here with a pre-assembled wing modification in place.rnDetailing progress on the side-of-body reinforcement, 787 Vice President and General Manager Scott Fancher says despite the overall delays caused by the modification, Boeing "did it the right way, no corners were cut." The need for local structural reinforcement became clear during analysis of the "wing up-ending" phases of the full-scale static test when "we saw there were stresses being distributed throughout the joint in a way we hadn't predicted," says Fancher.
