SEATTLE (CBS Seattle) – Boeing has discovered another manufacturing error in some 787 Dreamliners, possibly further delaying delivery of the aircraft.
According to The Seattle Times and a source with knowledge of the situation, the manufacturing error is causing delamination in the plastic-composite aft fuselage section of the planes.
Boeing is inspecting all the airplanes already built to find the extent of the issue.
In a statement Sunday, Boeing said, “We have the issue well defined and are making progress on the repair plan. There is no short-term safety concern.”
An issue arose in 2010 with construction of the 787’s horizontal tail in Italy. Mechanics had applied too much torque when tightening fasteners and the consequent compression degraded the composite material.
Those manufacturing problems added months of delays to the jet program. The plane entered service in 2011 after more than three years of delays.
Boeing has received 870 orders for the 787 from various airlines. They have completed assembly of about 50 Dreamliners, and delivered five, to All Nippon Airways of Japan.
All Nippon Airways is the airline that ordered the most Dreamliners (55), followed by Quantas (50) and United Airlines (50). The International Lease Finance Corporation, an aircraft lessor that leases jetliners to airlines around the world, including Seattle-based Alaska Airlines, has an order for 74 Dreamliners.
