On April 6, Spirit AeroSystems received notice from Boeing (Chicago, Ill., U.S.) that all deliveries to Boeing's Washington state and South Carolina facilities are suspended until further notice due to Boeing's indefinite production suspension at the sites. As a result, Spirit has halted production for Boeing programs, subject to certain exceptions, performed at its facilities in Wichita, Kansas, and in Tulsa and McAlester, Oklahoma for an indefinite period of time. Spirit Defense work as well as Airbus and other non-Boeing work will continue at such facilities.
