ABSTRACT:
The problem solved by this invention is to eliminate an oil can movement of the web of an aircraft pressurized bulkhead. A hat section support stiffener is attached to the web by an adhesive. Two end brackets are attached by Hi-Loc bolts to bulkhead stiffeners and the end brackets are attached and arranged to provide a downward pressure on the hat section stiffener to assist in holding it in place. This invention is characterized by the absence of any new fasteners passing through the fatigue critical bulkhead web and also is characterized by the absence of any requirement for removal of existing fasteners, including, but not limited to those passing through the bulkhead web.
