ABSTRACT:
A crashworthy aircraft fuel storage system normally operative so that the fuel tank, fuel shut-off valve assembly and the fuel inlet connection to the fuel tank are normally assembled to be free floating with respect to the aircraft structure, and further operative so that crash load conditions will cause the fuel tank to move with respect to the aircraft structure to thereby cause fuel inlet fitting to move therewith and into contact with the aircraft structure so as to impose a momentum force on the fuel shut-off valve assembly to cause fracture thereof and separation of the fuel tank from the fuel inlet fitting, with both parts so separated, sealed to prevent fuel flow therethrough.
