Each stator vane segment includes an inner radial platform, an outer radial platform, at least one airfoil extending between said platforms, and a first mounting flange extending radially outward from said outer radial platform. Each first mounting flange is aligned with a second mounting flange extending radially inward from an outer case surrounding the stator vane assembly. Each fastener includes a bolt extending through the first and second mounting flanges, a nut for threaded engagement with the bolt, and apparatus for preventing vibration of the fasteners.
