WASHINGTON (Reuters) -Boeing mentioned on Tuesday it’s slowing deliveries of its 787 Dreamliner after the corporate found a brand new manufacturing flaw, however expressed optimism that it could actually nonetheless ship 70-80 of the widebody jets this yr as deliberate.
The issue, which doesn’t pose a flight security concern, includes a becoming for the 787’s horizontal stabilizer put in by a Boeing manufacturing facility in Salt Lake Metropolis, Utah, the corporate mentioned.
Boeing might want to examine all 90 Dreamliners in its stock earlier than they are often delivered, and it expects it should take two weeks to repair every plane, the corporate added.
The horizontal stabilizer, positioned on the base of an plane’s tail, permits a airplane to keep up longitudinal stability whereas flying. Boeing mentioned it discovered final week that the becoming included shimming – a fabric that fills gaps between the surfaces of an plane – that was improperly sized and didn’t meet specs. On Friday, it stopped ticketing 787s suspected to have the flaw for supply, the corporate mentioned.
The problem doesn’t instantly have an effect on in-service 787s, Boeing mentioned, however the firm couldn’t say how far again the problem stretches or whether or not Dreamliners at present operated by airways will want a repair.
Boeing, which introduced final week that it had elevated 787 manufacturing from three to 4 jets a month, mentioned the problem has not precipitated a halt in 787 manufacturing.

The FAA usually delegates airplane ticketing authority to the producer. However in some cases, just like the 737 MAX and 787, it has retained accountability for approving every new airplane.
Boeing mentioned it has notified clients that rework “will have an effect on timing of near-term 787 deliveries” however added that it believes it could actually nonetheless ship 70-80 Dreamliners this yr.
The 787’s newest drawback mirrors manufacturing points found over 2020-2021, which included improperly fitted shimming that led to paper-thin gaps between surfaces on the Dreamliner’s fuselage.
Boeing stopped 787 deliveries at a number of factors throughout that interval, resuming them final August after agreeing to an FAA-approved modification plan for Dreamliners within the firm’s stock.
The corporate confronted one more 787 supply stoppage in February after Boeing discovered a knowledge evaluation error relating to ahead strain bulkhead that was unrelated to the shimming drawback. In March, the FAA mentioned it could permit Boeing to restart 787 deliveries, because the U.S. planemaker had addressed considerations.
The most recent 787 manufacturing defect comes as Boeing grapples with a 737 bracket set up problem disclosed in April, which slowed deliveries of the cash-generating household of narrowbody jets, together with the bestselling MAX 8 mannequin.
Boeing CEO Dave Calhoun in April known as the issue a “gnarly defect” that was practically unimaginable for employees to visibly assess. The corporate mentioned final month it had begun delivering reworked 737s.
