## Discrepancy

NR 2 ENG EVIDENCE OF FIRE AT FUEL HYDRAULIC DISCONNECT AREA.  HEAT SHIELD IS BURNED AND LINERS ARE DAMAGED.   DURING TROUBLESHOOTING FOUND BURNED HEAT SHIELD BUT NO HYD FLUID RESIDUE.  DISCOVERED BALLOON IN FUEL SUPPLY LINE.  AFTER REPLACING FUEL & HYD LINES, HEAT SHIELD & INSULATION, PERFORMED MOTORING TO VERIFY FIX.  REPLACEMENT FUEL LINE ALSO BALLOONED.  SECOND REPLACEMENT LINE OK.
