A bore metrology method includes aligning a first structure, which defines an initial bore, with a second structure, which defines a pilot bore, such that the initial bore is partially obstructed by the second structure and the pilot bore is superimposed with the initial bore. The initial bore includes a bore locating target assembly within the initial bore, the bore locating target assembly having an optical target, the optical target having a reflector and an optical absorbing feature, the optical absorbing feature defining a pattern on the optical target. At least a portion of the reflector and at least a portion of the pattern are visible through the pilot bore. The method further includes imaging the portion of the reflector and the portion of the pattern that are visible through the pilot bore. The method further includes determining a centerline of the initial bore based on the imaging.

A method includes making a first structure with a first plurality of pre-drilled holes at pre-defined locations, making a second structure with a second plurality of pre-drilled holes at pre-defined locations, making a third structure without pre-drilled full-size holes, measuring the location and orientation of the first and second plurality of pre-drilled holes in the first and second structures, determining the location of a third plurality of holes to be drilled in the third structure that correspond to first and second plurality of pre-drilled holes measured in the first and second structures, creating a program to drill the third plurality of holes in the third structure that align with the measured location and orientation of the first and second plurality of pre-drilled holes in the first and second structures based on the measure location and orientation of the first and second plurality of pre-drilled holes in the first and second structure, drilling the third plurality of holes in the third structure based on the program, positioning the third structure on the first and second structures such that the third plurality of holes in the third structure are aligned with the first and second plurality of pre-drilled holes in the first and second structures, and inserting fasteners through the third plurality of holes and the first and second plurality of predrilled holes that are aligned with the third plurality of holes to secure the second structure to the first structure using the third structure.

Fuselage sections having tapered wing rib interfaces are disclosed. A disclosed example apparatus includes a rib associated with a fuselage section, and a wing interface surface defined by the rib, where the wing interface surface is tapered relative to a longitudinal axis of the fuselage section from an aft end of the fuselage section to a fore end of the fuselage section.

A method of assembling thin-walled curvilinear components to a bulkhead offers a cost-effective, time-saving process of manufacture. Each component includes a faying edge configured to be aligned with respect to the other. A first component and the bulkhead are preassembled. In one approach, a second component is clamped about the bulkhead for a preassembly measurement of radial gaps between the faying edge of the second component and the bulkhead. An average value of the radial gaps is calculated, and a specific shim thickness corresponding to the calculated average gap value is selected. The second component is unclamped, and a plurality of shims, each having the selected thickness corresponding to the calculated average gap value, is applied about the bulkhead. The second component is then permanently secured to the bulkhead over the shims, with respective faying edges of the first and second components fixed in radial alignment with each other.
