Each body segment includes a first face, a second face, a number of passages for receiving cooling air disposed between the faces, a second attachment apparatus, and a post for biasing each the body segment in contact with the aft seal ring. The first and second attachment apparatus cooperate to suspend the blade outer seal segments in close proximity to the rotor assembly.
