    Abstract: An assembly for mounting an auxiliary component to an engine case for a gas turbine engine includes a support bracket and a locator. The locator includes a fusible guide pin extending at least partially into a first aperture disposed in the support bracket, and a catcher pin extending at least partially into a second aperture disposed in the support bracket. The fusible guide pin is configured to fracture to absorb energy while the catcher pin limits system displacement during and post an overload event, thus reducing the energy transmitted to the auxiliary component (e.g., a gearbox housing). The locator can further include an anti-rotation pin extending from the plate member and configured to be received by the auxiliary component. The anti-rotation pin prevents rotation of the locator, about a third pin of the locator, with respect to the auxiliary component when the fusible guide pin is broken.

    Abstract: A gas turbine sealing interface to seal a gap between a transition duct and a turbine section component is provided. The transition duct includes an outlet exit frame including at least one fastener hole. The turbine section component includes a first stage vane structure including an upstream lip. A seal couples the outlet exit frame to the first stage turbine vane structure. An L-shaped rail including a flat portion and a lipped portion disposed perpendicularly to the flat portion. The seal is secured to the outlet exit frame via the L-shaped rail. An upstream portion of the seal includes a U-shaped cross section forming a first groove. A downstream portion of the seal comprises a groove which engages the upstream lip of the first stage turbine vane structure. A gas turbine engine including a radially inner sealing interface and a radially outer sealing interface is also provided.
