Claim 12:
13. A method of making a pressure bulkhead assembly, the method comprising steps of:
determining first locations of a plurality of first holes, pre-drilled in an aft pressure bulkhead;
determining first orientations of the plurality of first holes in the aft pressure bulkhead;
determining a first surface profile of a first interface surface of the aft pressure bulkhead;
determining a second surface profile of a second interface surface of each one of a plurality of splice angles that corresponds to an associated portion of the first interface surface of the aft pressure bulkhead, wherein the plurality of splice angles is configured to be coupled to the aft pressure bulkhead;
determining second locations and second orientations of a plurality of second holes to be drilled in the plurality of splice angles, wherein the plurality of second holes correspond to the plurality of first holes in the aft pressure bulkhead;
receiving the second surface profile of the second interface surface of each one of the plurality of splice angles and the second locations and the second orientations of the plurality of second holes to be drilled in each one of the plurality of splice angles associated with corresponding ones of the plurality of first holes in the aft pressure bulkhead;
aligning each one of the plurality of splice angles on a CNC machine; and
drilling the plurality of second holes in each one of the plurality of splice angles through the second interface surface and at the second locations and the second orientations.
