Further, the member has a first and a second surface with a thickness defined there between that is varied. The method includes leaving the member on the structure. Also, the method includes advancing a tool through the member while on the structure. The tool is stopped before the tool advances into the structure by more than about a first pre-selected tolerance. Also, a mobile platform assembly is provided that includes a structure, a member, and a fastener fastening the structure and member via a hole through the structure and assembly. The hole has a first diameter through the structure and a second diameter through the member, wherein the diameter changes within an acceptable depth range. In another preferred embodiment, a boroscope, adapted for inspecting holes having two diameters, is also provided.
