Zusammenfassung:	A stator vane (60) for a gas turbine engine includes an airfoil (78) that extends radially from a first side of a platform (76). A pocket (90) is provided in the platform (76) on a second side opposite the airfoil (78). Forward and aft rails (100,102) extend from the second side of the platform (76). One of the forward and aft rails (100,102) includes a radial surface (118). An impingement plate (108) is secured to the platform (76) over the pocket (90). The impingement plate (108) includes a radial wall (120) that engages the radial surface (118).
