## Discrepancy

WHILE ON GROUND WITH APU RUNNING, A MAJOR FUEL LEAK WAS SEEN COMING OUT THE REAR FUSELAGE.  APU WAS SHUTDOWN AND AN INVESTIGATION REVEALED A BROKEN FUEL LINE AT ONE OF THE FUEL NOZZLES. THE FUEL WAS SPRAYING INSIDE THE APU ENCLOSURE AND LEAKING OUT FUSELAGE ACCESS PANELS AND DRAINS. HAZMAT CREWS WERE CALLED TO CLEAN UP THE FUEL SPILL. THIS IS A MODIFIED GII WITH A GTCP36-150J, APU.
