An anti-rotation device for preventing rotation of a damper spring and an inner air seal in a stator assembly is provided. The anti-rotation device is formed by a lug positioned within a slot at a center of an inner air seal arc segment. The lug engages a slot in the damper spring and a cutout in a stator segment so as to prevent rotation of the damper spring and the inner air seal in either direction relative to the stator assembly.
