a mounting system that couples the mount post of the blade track segment with the first attachment flange and the second attachment flange of the carrier,

wherein the first attachment flange is formed to define at least one flange slot that extends axially through and radially into the first attachment flange such that a radially inner end of the at least one flange slot opens radially inwardly, and wherein a radially outward end of the at least one flange slot terminates radially at or before the outer wall.

8. The turbine shroud of claim 7 , wherein the outer wall, the first attachment flange, and the second attachment flange form a single, one-piece, integral component.

9. The turbine shroud of claim 7 , wherein the first attachment flange is spaced apart from the second attachment flange to define a channel therebetween and no holes extend through the outer wall of the carrier that open into the channel.

10. The turbine shroud of claim 9 , wherein the mount post is the only mount post included in the blade track segment and is located in the channel axially between the first attachment flange and the second attachment flange.

11. The turbine shroud of claim 7 , wherein the outer wall is formed to define relief slots that extend axially forward from an aft terminating end of the carrier partway through the outer wall and terminate axially at or before a forward terminating end of the carrier.

12. The turbine shroud of claim 7 , wherein the carrier includes an inner wall that extends between the forward attachment flange and the aft attachment flange, and wherein the blade track segment further includes a second mount post that is spaced apart axially from the mount post and wherein the first attachment flange, the second attachment flange, and the inner wall are located axially between the mount post and the second mount post.

13. The turbine shroud of claim 7 , wherein the carrier includes an inner wall that is spaced apart radially inward away from the outer wall and extends between and directly connects terminating ends of the first attachment flange and the second attachment flange.

14. The turbine shroud of claim 13 , wherein the inner wall is formed to define cooling holes that extend radially through the inner wall to direct air toward the shroud wall.

15. The turbine shroud of claim 13 , wherein the outer wall, the first attachment flange, the second attachment flange, and the inner wall cooperate to define the channel and the channel extends radially inward into the carrier and opens radially outward.
