Boeing Co supplier Alenia Aeronautica halted production of two major 787 structural components due to manufacturing flaws, an aviation industry blog said.
FlightBlogger said production was halted because of wrinkles in the fuselage skin caused by flaws in subcomponents of the one-piece composite barrel.
The blog cited a letter, signed and dated June 23, on a Boeing letterhead. On June 23, Boeing postponed the first test flight of its 787 Dreamliner for a fifth time. Boeing could not immediately be reached for comment.
Alenia Aeronautica, a unit of Italy's aerospace and defense company Finmeccanica SpA , is supplying 14 percent of the fuselage of the B787 plane.
Alenia Aeronautica is a key player in the development of the 787 aircraft's main structure and builds carbon fiber pieces for the aircraft.
Flaws were found on 23 airplanes, starting with the seventh in production, Boeing spokeswoman Loretta Gunter told Bloomberg. She added that a solution has been designed and patches will be applied to all the planes built so far.
