Zusammenfassung:	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 blade outer air seal has a plurality of segments arranged circumferentially about the axis of rotation and mounted in a support structure radially outward of the outer tip. Each of the segments have a radially inner surface and a radially outer surface and four hooks protruding radially outward from the radially outer surface and extending along the segment in an axial direction.
