Abstract: A bearing support includes a squirrel cage including a fenestrated portion with a plurality of circumferentially spaced apart windows defined therethrough. A bearing support cage inboard of the squirrel cage defines a plurality of circumferentially spaced apart windows therethrough. The bearing support cage is operatively connected to the squirrel cage to support a bearing from within the squirrel cage.

Abstract: A gas turbine engine includes a service line interface that extends from an outer surface of a bearing support such that a heat shield is spaced from the outer surface. A method of mounting a heat shield to a gas turbine engine includes trapping a heat shield within a gapped overlap spaced from an outer surface of a bearing support.
