Alenia Aeronautica has halted production of two major 787 structural components due to wrinkles in the fuselage skin caused by manufacturing flaws in subcomponents of the one-piece composite barrel, according to a letter obtained by Flightglobal affiliate FlightBlogger.

The letter's subject: "Section 44 and 46 stop work order for barrel" details a correspondence between Jay Campbell, sr. manager for supplier management for the 787 fuselage supply chain, James E. Simmons section 44/46 sr. engineering manager and Ciro Occipinti of Alenia Aeronautica in Naples, Italy.

The letter, signed and dated 23 June on Boeing letterhead, was sent the same day Boeing announced the latest delay in the program citing a need to reinforce the side of body structure, FlightBlogger reports.
