## Discrepancy

FUEL LEAKAGE WAS DETECTED ON BOTH FUEL TANK SUMP PLATES. RH FUEL SUMP PLATE LEAKAGE WAS DRIPPING ONTO FIRESHIELD ABOVE EXHAUST DUCT (ENGINE EXHAUST). SUMP PLATES FASTENERS FOUND WITH CORRECT TORQUE. MOST LIKELY CAUSE IS AGING OF SEALANT BETWEEN CELL AND SUMP PLATES. (MIL-S- 8784B 1/2).  SUGGESTION: HAVE MANUFACTURE INSTALL A REGULAR GASKET INSTEAD OF RELYING ON TECHNICIAN TO MANUFACTURE ONE WITH SEALANT.
