A turbine shroud assembly adapted for use with a gas turbine engine , the shroud assembly comprising a carrier shaped to include an outer wall that extends circumferentially at least partway about an axis , a forward support wall , an aft support wall spaced axially from the forward support wall , and a central support wall located axially between the forward support wall and the aft support wall , the forward support wall , the aft support wall , and the central support wall extend radially inward from the outer wall , a seal segment shaped to include a runner that extends circumferentially partway around the axis , a forward mount flange that extends from the runner into a forward space between the forward support wall and the central support wall of the carrier , and an aft mount flange that extends from the runner into an aft space between the aft support wall and the central support wall of the carrier , and a mount assembly including a split-pin fastener that couples the seal segment with the carrier , the split-pin fastener being made up of a forward pin that extends axially through the forward mount flange of the seal segment into both the forward support wall and the central support wall of the carrier , an aft pin circumferentially aligned with the forward pin that extends axially through the aft mount flange of the seal segment into both the aft support wall and the central support wall of the carrier , and a connector that extends between and interconnects the forward pin and the aft pin , characterised in that the connector is configured to separate the forward pin and aft pin during use of the turbine shroud assembly in the gas turbine engine . a carrier shaped to include an outer wall that extends circumferentially at least partway about an axis , a forward support wall , an aft support wall spaced axially from the forward support wall , and a central support wall located axially between the forward support wall and the aft support wall , the forward support wall , the aft support wall , and the central support wall extend radially inward from the outer wall , a seal segment shaped to include a runner that extends circumferentially partway around the axis , a forward mount flange that extends from the runner into a forward space between the forward support wall and the central support wall of the carrier , and an aft mount flange that extends from the runner into an aft space between the aft support wall and the central support wall of the carrier , and a mount assembly including a split-pin fastener that couples the seal segment with the carrier , the split-pin fastener being made up of a forward pin that extends axially through the forward mount flange of the seal segment into both the forward support wall and the central support wall of the carrier , an aft pin circumferentially aligned with the forward pin that extends axially through the aft mount flange of the seal segment into both the aft support wall and the central support wall of the carrier , and a connector that extends between and interconnects the forward pin and the aft pin , characterised in that the connector is configured to separate the forward pin and aft pin during use of the turbine shroud assembly in the gas turbine engine . <EOS>
