Spirit has notified our customer, Boeing, that we have identified a quality issue on the aft fuselage section of certain models of the 737 fuselage that Spirit builds. This is not an immediate safety of flight issue. We have processes in place to address these of types of production issues upon identification, which we are following. Spirit is working to develop an inspection and repair for the affected fuselages. We continue to coordinate closely with our customer to resolve this matter and minimize impacts while maintaining our focus on safety.
