That Spirit location has the worst performance of all of the other Spirit locations; they were about to but cut loose however I think Spirit's largest customer may have had a hand in stopping that from happening. I know they haven't been accepting any new proposals lately
Their "legacy" programs (737, 777, 747) have been decent, it's the 787 program and the Gulfstream programs that are struggling. I'd almost bet that if it was only the 787 leading edges they had there, Boeing would have cut and run by now. Spirit has already moved their 787 fixed leading edge line entirely to their Malaysia facility, and is only building moveable leading edges for the 787 in Tulsa. We'll see what the future buyout brings.
