## Discrepancy

WHILE WAITING FOR PASSENGERS WITH THE APU RUNNING FUEL BEGAN RUNNING OUT OF THE BACK OF THE AIRCRAFT NEAR THE PANEL WHERE THE MARKER BEACON ANTENNA IS MOUNTED. APU WAS IMMEDIATELY SHUT DOWN AND THE FIRE DEPARTMENT CONTACTED. UPON INSPECTION OF THE APU IT WAS NOTED THAT ONE OF THE SECONDARY FUEL MANIFOLD ASSEMBLIES HAD FAILED DUE TO CRACKING CAUSING FUEL TO SPRAY INTO THE APU COMPARTMENT AND RUN OUT OF THE AIRCRAFT ONLY WHILE THE APU WAS RUNNING.
