Abstract
An apparatus and method for inspecting a dovetail slot of a gas turbine engine disk, including: a first pin member fixed in a stationary position; a second pin member having the ability to move between a first position and a second position, wherein the second pin member is oriented substantially parallel to the first pin member; a member actuable between a first position and a second position, wherein the member functions to automatically position the first and second pin members in a predetermined position within the dovetail slot when in the second member position; a first probe for measuring a distance between the first and second pin members when in the predetermined dovetail slot position; and, at least one plate member forming a base to which the first pin member, the second pin member, the actuable member, and the first probe are assembled in a predetermined manner.
