Boeing testing Dreamliner cockpit windows as flaws search widens

Boeing is scrutinising the flight-deck windows of some of its 787 Dreamliners as the beleaguered planemaker expands its search for potential manufacturing flaws that have delayed deliveries of its marquee jetliner, according to people briefed on the matter. Boeing has been testing the cockpit windows in a limited batch of aircraft after learning a supplier modified its production process, two of the people said, asking not to be identified because the matter is sensitive. Boeing wants to ensure the windows still meet its requirements after the change, but the testing isn't expected to affect March deliveries, one of the people said. The emergence of yet another potential glitch comes as Boeing's mechanics and engineers work furiously to try and restart 787 Dreamliner deliveries by the end of this month, in line with what executives promised during a January earnings call. The US manufacturer hasn't handed over any of the jets since October after discovering more of the tiny dimples in the inner lining where the carbon-fiber fuselage barrels are fused to form the jet's frame. New issues with the plane could pose problems for shipments beyond this month, making it more difficult for Boeing to meet its delivery target for the year.<br/>
