The pressure deck also includes a box structure between a middle pair of the beams and configured to transfer load forward to a rear spar of a wing of the aircraft and aft to an aft wheel well bulkhead of the aircraft. The pressure deck further includes a first intercostal outboard from the box structure and configured to stabilize a first outboard pair of the beams, and a second intercostal outboard from the first intercostal and coupled between a second outboard pair of the beams via a swing link to allow the second intercostal to flex laterally.
