Boeing finds new defect in continuing struggle to produce Dreamliner 787

Boeing said Thursday that some titanium 787 Dreamliner parts were improperly manufactured over the past three years, the latest in a series of problems to plague the wide-body aircraft. The quality issue does not affect the immediate safety of flights, the company said, adding it had notified the Federal Aviation Administration (FAA). Boeing is working to determine how many planes contain the defective part. Boeing said the parts were provided by Leonardo SpA (LDOF.MI), which bought the items from Italy-based Manufacturing Processes Specification (MPS). MPS is no longer a supplier to Leonardo, Leonardo confirmed. Shares in Italy's Leonardo extended losses and closed down 7%. Boeing shares closed down 2%. Leonardo said the issues are ascribed to MPS. Leonardo said that MPS "is under scrutiny by prosecutors therefore Leonardo is (an) injured party and will not bear any potential costs associated with this issue."<br/>
