Abstract: A blade outer air seal includes a base portion. A first wall and a second wall extend radially from the base portion. The first wall is axially spaced from the second wall. The first and second walls extend in a circumferential direction. A first hook extends from the first wall and a second hook extends from the second wall. The first and second hooks extend in an axial direction towards one another to form a passage that extends in the circumferential direction. The passage is configured to receive a carrier. A tab extends radially outward from the second hook. The tab is configured to engage with the carrier.

Abstract: A turbine section for a gas turbine engine includes a turbine blade that extends radially outwardly to a radially outer tip and for rotation about an axis of rotation. A support structure is arranged circumferentially about the axis of rotation and has a plurality of attachment members that extend radially inwardly. A blade outer air seal has a plurality of segments mounted in the support structure. Each segment has a first wall circumferentially spaced from a second wall. The first and second walls are joined to a base portion and an outer wall to define a passage that extends axially along the segment.
