1. An apparatus for a turbine engine, comprising:
an air seal configured to rotate about an axis, the air seal extending axially along the axis between a first side and a second side, and the air seal including an axial flange, a radial flange, a seal element, a retainer neck and a retainer head;
the axial flange extending axially to the second side of the air seal;
the radial flange connected to the axial flange at the second side of the air seal, and the radial flange projecting radially outward from the axial flange to a distal end;
the seal element projecting radially outward from the distal end of the radial flange;
the retainer neck connected to the radial flange at the distal end of the radial flange, and the retainer neck projecting axially out from the radial flange towards the first side of the air seal and then projecting radially outward to the retainer head;
the retainer head projecting axially towards the first side of the air seal and away from the retainer neck to an axial end of the retainer head; and
a first groove projecting radially into the axial flange from an inner side of the axial flange, and the first groove located axially between the radial flange and the first side of the air seal.
