Spirit AeroSystems issued the following statement on Aug. 23:
"We are aware of a quality issue involving elongated fastener holes on the aft pressure bulkhead on certain models of the 737 fuselage produced by Spirit AeroSystems. Because Spirit uses multiple suppliers for the aft pressure bulkhead, only some units are affected. Spirit will continue to deliver units to Boeing.
"Spirit has implemented changes to its manufacturing process to address this issue. We are working closely with our customer to address any impacted units within the production system and address any needed rework. Based upon what we know now, we believe there will not be a material impact to our delivery range for the year related to this issue.
"Boeing has determined that there is no immediate safety of flight concern associated with this issue for the 737 fleet and that the in-service fleet may continue to operate."
