## Discrepancy

ENGINE EXPERIENCED WHAT APPEARED TO BE A STALL FOLLOWED BY A FIRE WARNING.  ENGINE WAS SHUT DOWN AND AN AIR TURN-BACK ACCOMPLISHED.  CORE COWL DAMAGE WAS OBSERVED IMMEDIATELY AFTER LANDING. SUBSEQUENT INVESTIATION IDENTIFIED A CRACKED FUEL HYDRAULIC LINE.  THE DEFECT CONSIDERED THE LIKELY CAUSE OF EXCESS FUEL SPILLAGE AND IGNITION SOURCE WITHIN NACELLE ENVIRONMENT.  MODERATE FIRE DAMAGE WAS OBSERVED IN IMMEDIATE VACINITY OF FAILED TUBE.
