## Discrepancy

SECURE 'B' NUT AND SAFETY.  LEAK CHECK GOOD.  FUEL LEAK AT NR 2 ENGINE PYLON DRAIN LINE.  REPLACING COUPLING FOR MAIN FUEL LINE INSIDE OF DRAIN-BOX JUST ABOVE J-BOX UNDER NR 2 REV HALF.  COUPLING AND BONDING WIRE CLAMPS HAVE SEALANT OVER THEM MAKING REMOVAL DIFFICULT.  NR 2 ENGINE FOUND WITH STANDING FUEL IN EXHAUST CASE AND LPT CASE, SEVERAL GALLONS.
