A wing skin, which was secured to a wing structure by a plurality of fasteners extending through the wing skin, is removed from the wing and aligned with a template. Template holes are drilled through the template corresponding to each of the fastener holes of the wing skin. The template is then aligned with a new wing skin, and pilot holes are drilled through the new wing skin corresponding to each of the template holes. The new wing skin is then aligned with the wing structure such that the pilot holes permit access to corresponding fastener holes of the wing structure. A mill bit is then positioned through each pilot hole and aligned with the center of the corresponding consumable bushing in the fastener hole of the wing sub-structure, and the skin pilot holes are milled to form fastener holes in the new wing skin aligned with existing sub-structure.

1. An assembly comprising: an existing underlying wing structure;a mill bit; anda consumable bushing to facilitate alignment of a new wing skin having a plurality of pilot holes therein onto the existing underlying wing structure having a plurality of fastener holes therein corresponding to each of the plurality of pilot holes,wherein the consumable bushing comprises: a cylindrical body portion having a first diameter, a first end, and a second end, and defining a guide hole having a second diameter and extending through the cylindrical body between the first end and the second end; anda thin flange extending outward away from the cylindrical body at least partially around the cylindrical body near the first end such that the thin flange has at least one dimension greater than the first diameter;wherein: the first diameter is sized such that the cylindrical body fits snugly within one of the fastener holes of the underlying wing structure such that the thin flange is positioned adjacent the underlying wing structure and the guide hole is aligned with the fastener hole and is accessible through a corresponding pilot hole of a new wing skin aligned relative to the underlying wing structure such that the mill bit may be positioned through the pilot hole and into the guide hole; andthe cylindrical body portion and the thin flange are consumable such that the cylindrical body and the thin flange are configured to be cut by the mill bit as the mill bit enlarges the pilot hole of the new wing skin. 2. The assembly of claim 1, wherein the first diameter is substantially the same as a diameter of the fastener holes of the underlying wing structure. 3. The assembly of claim 1, wherein the guide hole is a concentric hole extending through the cylindrical body portion. 4. The assembly of claim 1, wherein the guide hole has a diameter smaller than the first diameter. 5. The assembly of claim 1, wherein the guide hole has a diameter that corresponds to a diameter of the mill bit. 6. The assembly of claim 1, wherein the mill bit has a diameter that is negligibly smaller than a diameter of the guide hole. 7. The assembly of claim 1, wherein the guide hole has a diameter smaller than the pilot hole of the new wing skin. 8. The assembly of claim 1, wherein the thin flange has a diameter greater than the first diameter. 9. The assembly of claim 1, wherein the thin flange is concentric with the cylindrical body portion. 10. The assembly of claim 1, wherein the thin flange is circular shaped. 11. The assembly of claim 1, wherein the thin flange has a shape selected from the group consisting of: square, rectangular, triangular, regular polygonal shape, irregular polygonal shape, and non-polygonal two-dimensional. 12. The assembly of claim 1, wherein the thin flange is positioned at the first end of the cylindrical body portion. 13. The assembly of claim 1, wherein the thin flange extends outward away from the cylindrical body around an entire perimeter of the cylindrical body near the first end of the cylindrical body. 14. The assembly of claim 1, wherein the bushing is made of a material different than a material of any one or more of the mill bit, the wing skin, the skin template, or the existing underlying wing structure. 15. An assembly comprising: an existing underlying wing structure;a mill bit; anda consumable bushing configured to facilitate alignment of a new wing skin having a plurality of pilot holes therein onto the existing underlying wing structure having a plurality of fastener holes therein corresponding to each of the plurality of pilot holes,wherein the consumable bushing comprises: a cylindrical body portion having a first diameter, a first end, and a second end, and defining a guide hole having a second diameter and extending through the cylindrical body between the first end and the second end, and wherein the guide hole is substantially concentric with the first diameter; anda thin flange extending outward away from the cylindrical body at least partially around the cylindrical body at the first end such that the thin flange has a flange diameter greater than the first diameter;wherein: the first diameter is sized such that the cylindrical body fits snugly within one of the fastener holes of the underlying wing structure such that the thin flange is positioned adjacent the underlying wing structure and the guide hole is substantially concentric with the fastener hole and is accessible through a corresponding pilot hole of a new wing skin aligned relative to the underlying wing structure such that the mill bit may be positioned through the pilot hole and into the guide hole; andthe cylindrical body portion and the thin flange are consumable such that the cylindrical body and the thin flange are configured to be cut by the mill bit as the mill bit enlarges the pilot hole of the new wing skin. 16. The assembly of claim 15, wherein the guide hole is negligibly larger than a diameter of a pilot guide of the mill bit. 17. The assembly of claim 15, wherein a pilot guide of the mill bit has a diameter that is negligibly smaller than a diameter of the guide hole. 18. The assembly of claim 15, wherein the guide hole has a diameter smaller than the pilot hole of the new wing skin. 19. The assembly of claim 15, wherein: the thin flange is concentric with the cylindrical body portion; andthe guide hole is substantially concentric with the first diameter. 20. The assembly of claim 15, wherein the thin flange is circular shaped.
