An airfoil assembly (48) is described comprising an airfoil (50), a band (61) coupled to the airfoil (50) for providing at least a portion of support for the airfoil (50) in the airfoil assembly (48) and a slot (70) capable reducing stress in the airfoil (50) wherein the slot (70) is located in the band (61) near a portion of the airfoil (50). A compression system (90) is described comprising a stator assembly (42) comprising a plurality of arcuate vane sectors (44) arranged circumferentially around a longitudinal axis (11), each vane sector (44) comprising an airfoil (50), an arcuate inner band (80) and an arcuate outer band (60) coupled to the airfoil (50), and a slot (70) capable of reducing stress in the airfoil (50), the slot (70) being located in the vane sector (44) near a portion of the airfoil (50). A method of manufacturing (500) an airfoil assembly (48) is described
