Abstract: A gas turbine engine includes first and second structures secured to one another at a bolted flange joint. A seal is supported by a third structure. A cover is arranged over the bolted flange joint and discrete from the first and second structures. The cover provides a seal land that engages the piston seal and protects the first structure from the adverse thermal environment.

Abstract: A runner assembly includes a runner with an aperture, a cradle, and a fastener. The cradle includes a planar base with an aperture, a tab extending from the base, and fingers extending from the base. The fastener extends through the apertures for attaching the runner to the cradle, and the fingers are adjacent to the runner and constrain the runner with respect to the cradle and the fastener.
