An example airfoil assembly (20) includes an airfoil body (22) extending between a leading edge, a trailing edge, a suction side, and a pressure side. The assembly further includes a first protective sheath (34), an indicator sheath (72), and a second protective sheath (60). The first protective sheath (34) has an outer side (36) and an inner side (38) that forms a cavity for receiving at least a portion of the airfoil body (22). The inner side being bonded to the leading edge of the airfoil body. A portion of the indicator sheath (72) is positioned forward the first sheath (34) relative to the leading edge of the airfoil. A portion of the second protective sheath (60) is positioned forward the indicator sheath (72) relative to the leading edge of the airfoil.
