A source with knowledge … The high capacity 787-3 would have been popular in Japan. Its six-month delay is largely due to Boeing attempting to rethink its product development, production processes and supply chain management in one fell swoop. FAA Investigating Boeing 787 Structural Defects. Boeing said Tuesday it is inspecting part of the tail of the two-aisle 787 after finding that pieces were clamped together too tightly, which could lead to premature fatigue of a part called the horizontal stabilizer. A former employee of Boeing who has been laid off last year claims that the new carbon-composite airframe of the upcoming Boeing 787 Dreamliner may be unsafe.According to ATW News, Vince Weldon who had worked for Boeing for 46 years claims in an interview with journalist Dan Rather that he was fired in 2006 because he pointed out safety glitches in relation to this new breakthrough … The chief breakthrough material technology on the 787 is the increased use of composites. The Dreamliner is far more than just another ambitious product. The 787 Dreamliner was supposed to be a big jump forward for Boeing — notably, the first plane to be made entirely of composites rather than aluminum.
