A vane stage segment is provided including an outer wall segment, an inner wall segment, and an airfoil. The outer wall segment is configured to be coupled to other outer wall segments to form an outer wall of the vane stage. The inner wall segment is spaced radially inward from the outer wall segment. At least one of the inner wall segment or the outer wall segment is separable between a forward portion and an aft portion. The airfoil extends between the outer wall segment and the inner wall segment.
