Boeing will slow work on its 787 Dreamliner to fix a new problem.

Boeing said Tuesday that it would temporarily slow production of the 787 Dreamliner after it identified new work that needed to be done on the troubled wide-body jet. The slowdown will cause the company to fall short of a target production rate of five 787s per month as it conducts inspections and completes the extra work, Boeing said. Boeing also said that it expected to deliver less than half of the Dreamliners in its inventory this year, a shift from April when its CE, Dave Calhoun, said the company would hand over the majority by 2022. “We will continue to take the necessary time to ensure Boeing airplanes meet the highest quality prior to delivery,” the manufacturer said in a statement. “Across the enterprise, our teams remain focused on safety and integrity as we drive stability, first-time quality and productivity in our operations.” Boeing had stopped delivering the 787 last year amid quality concerns related to shims used where parts of the plane’s fuselage, or main body, are joined. The company resumed deliveries in March, but said in May that it had stopped again after the FAA said it was unconvinced by Boeing’s inspection methods, which relied on using a statistical analysis to identify where inspections were needed. Boeing said on Tuesday that discussions with the FAA are ongoing.<br/>
