NEW YORK — Boeing’s much-delayed 787 Dreamliner has hit another production problem.
Hairline cracks have been discovered in the wings of some 787s that are being built. The Chicago-based manufacturer said none of the 122 jets already flown by airlines around the world are affected.
“We are confident that the condition does not exist in the in-service fleet,” Boeing spokesman Doug Alder wrote in an email. “We understand the issue, what must be done to correct it and are completing inspections of potentially affected airplanes.”
The wings are produced by Japan’s Mitsubishi Heavy Industries.
