Boeing says it's discovered another problem with its long-delayed 787 jetliner.
The Chicago-based airplane maker said it has found microscopic wrinkles in the skin of the 787's fuselage and is installing a patch. The 787 is built for fuel efficiency from lightweight carbon composite parts.
Flaws were found on 23 airplanes, starting with the seventh in production, Crain's Chicago Business reported.
A Boeing Co. spokeswoman says the company ordered an Italian supplier, Alenia Aeronautica, to stop making the fuselage sections on June 23. She says patches will be installed at plants in Italy, Everett, Wash., and South Carolina.
Boeing has delayed the first test flight and deliveries of the 787 repeatedly, costing the company credibility and billions of dollars in anticipated expenses and penalties.
