Abstract: A near flow path seal member includes a seal body having a first end portion extending to a second end portion having a dovetail member. The first end portion includes a third end and a fourth end having a surface extending therebetween and facing away from the dovetail member, the surface having a longitudinal axis extending between the third end and the fourth end. A recess formed in the surface has a geometry to receive a seal element assembly having a base extending to at least one seal element. The seal element assembly is selectively installable or removable from the recess.
