A pressure bulkhead system is presented. The pressure bulkhead system comprises an aft pressure bulkhead having a bulkhead interface surface, skin splice angles positioned adjacent to one another and joined to the aft pressure bulkhead, and a plurality of shims between the flange surface and the bulkhead interface surface of the aft pressure bulkhead. The skin splice angles form a circumferential surface and a flange surface, wherein the circumferential surface has a nominal shape.
