Abstract
A borescope plug for a gas turbine engine includes a base attachable to a case and defining a base cavity, a shank having a base engagement element at a first end of the shank, and a plug member located at a second end of the shank, the plug member configured to plug a borescope aperture in a borescope vane cluster. The base engagement element fits within the base cavity such that the base moveably retains the base engagement element and wherein the base engagement element can move within the base cavity.

A borescope plug comprising:
- a base attachable to a case and defining a base cavity;
- a shank having a base engagement element at a first end of the shank;
- and
- a plug member located at a second end of the shank, the plug member configured to plug a borescope aperture in a borescope vane cluster,
- wherein the base engagement element fits within the base cavity such that the base moveably retains the base engagement element and wherein the base engagement element can move within the base cavity, and
- an integrally formed retainer that is integrally formed with the base, the integrally formed retainer defining a plurality of fingers defining a portion of the base cavity, the plurality of fingers arranged to receive the base engagement element in the base cavity when in an open position and are closable to movably secure the base engagement element within the base cavity.
