Abstract: A compressor case, and an associated method, repaired from damage to a segment of a stator ring hook. Two halves are engaged together at flange faces that define parting lines and that define a hollow interior, the ring hook being located at the interior, compressor case material having been removed at the stator ring hook location and a location of one of the flange faces to provide a space. A patch plug is slid into the space from the one flange face, the shape of the patch plug being complementary to a shape of the missing material space and inter-fitting therein, with an end of the patch plug being located at the one flange face to face an opposed half of the case with the two halves together. A fastener fastens the patch plug to the case and extending from the interior, through the patch plug, to the case.

Abstract: A fastener body comprises a head and a shank fabricated from a composite material. The head has at least one side which extends beyond the side of the shank and has two other sides coplanar with the shank.A fastener for engaging a liner has perpendicular lengthwise and widthwise reference axes and a head and a shank, with the shank extending in a first lengthwise direction away from the head, the head further having at least one extension that extends in the widthwise direction beyond the shank for engaging the liner, wherein substantially all lengthwise directed load components transmitted from the liner to the head are transmitted through the extension.
