1. A system for handling a gas turbine engine fan case comprising: a composite fan containment case, the composite fan containment case including a case outer surface, a case inner surface, and at least one main case aperture extending from the case outer surface through the case inner surface; andat least one shear puck, the at least one shear puck including a shear puck protrusion extending from a mounting plate of the at least one shear puck, the mounting plate being wider than the shear puck protrusion, and wherein the at least one shear puck is formed as a single piece;wherein the shear puck protrusion of the at least one shear puck is inserted into a respective one of the at least one main case aperture from the case outer surface, and wherein the shear puck protrusion engages the at least one main case aperture when inserted therein to allow the shear puck to react vertical lifting loads into the composite fan containment case. 2. The system of claim 1, further comprising at least one support structure affixed to the case outer surface, the at least one support structure comprising a main support structure aperture substantially aligned with the at least one main case aperture. 3. The system of claim 2, wherein the mounting plate has a first surface and a second surface and the shear puck protrusion extends from the second surface; and wherein a shear puck aperture extends from the first surface into the shear puck protrusion to form a cavity therein; and wherein the mounting plate is affixed to the at least one support structure. 4. The system of claim 2, wherein the at least one support structure further comprises: a plurality of support apertures, wherein the plurality of support apertures are located adjacent to the main support structure aperture; anda fastening device disposed within each of the plurality of support apertures. 5. The system of claim 4, wherein the fastening device comprises a fastening device inner surface, wherein the fastening device inner surface includes a plurality of threads disposed thereon. 6. The system of claim 4, wherein the fastening device comprises a fastening device proximal end, a fastening device distal end, and a flange extending from the fastening device distal end. 7. The system of claim 6, wherein the fastening device comprises a threaded flange bushing. 8. The system of claim 6, wherein the flange is in contact with the case inner surface. 9. The system of claim 1, wherein the shear puck protrusion includes a width dimension greater than or equal to approximately 1 inch. 10. A method of handling a composite fan containment case, the method comprising the steps of: (a) inserting at least one ground support device within a case handling system; and(b) transporting the case handling system to a desired location; wherein the case handling system comprises: the composite fan containment case, the composite fan containment case including a case outer surface, a case inner surface, and at least one main case aperture extending from the case outer surface through the case inner surface; andat least one shear puck, the at least one shear puck including a shear puck protrusion extending from a mounting plate of the at least one shear puck, the mounting plate being wider than the shear puck protrusion, and wherein the at least one shear puck is formed as a single piece;wherein the shear puck protrusion of the at least one shear puck is inserted into a respective one of the at least one main case aperture from the case outer surface, and wherein the shear puck protrusion engages the at least one main case aperture when inserted therein to allow the shear puck to react vertical lifting loads into the composite fan containment case. 11. The method of claim 10, wherein the case handling system further comprises: at least one support structure affixed to the case outer surface, each of the at least one support structures comprising a main support structure aperture substantially aligned with a respective one of each of the at least one main case apertures. 12. The method of claim 11, wherein the mounting plate has a first surface and a second surface and the shear puck protrusion extends from the second surface; and wherein a shear puck aperture extends from the first surface into the shear puck protrusion to form a cavity therein; and wherein the mounting plate is affixed to the at least one support structure. 13. The method of claim 12, wherein the at least one ground support device comprises: a ground support device first surface including a main first surface protrusion disposed thereon; anda ground support device second surface including a main second surface protrusion disposed thereon. 14. The method of claim 13, wherein inserting the first ground support device within the case handling system comprises inserting the main first surface protrusion into the cavity. 15. The method of claim 13, wherein transporting the case handling system to a desired location comprises: engaging the main second surface protrusion with a transporting device;lifting the case handling system via the transporting device;and moving the case handling system case to the desired location via the transporting device.
