## Discrepancy

DURING THE COURSE OF REPLACING THE LT MLG ASSEMBLY, THE TECHNICIAN, UPON VISUAL INSPECTION AFTER REMOVAL OF MLG ASSY, FOUND SIGNS OF CORROSION ON THE PLUG, P/N MY20112-1605.  UPON FURTHER DISASSEMBLY, IT WAS NOTED THAT THE CORROSION HAD GONE THROUGH THE PLUG. THE SEALANT ON ONE SIDE OF THE PLUG WAS PREVENTING FUEL LEAKAGE.  PART WAS ORDERED FROM MFG AND REPLACED WITH A NEW PLUG, P/N MY20112-1605-1. IT APPEARS THAT THE NEW PLUG HAS A DIFFERENT DESIGN AND PAINT PROTECTION SYSTEM; THUS AIDING IN THE PREVENTION OF FUTURE CORROSION. THE AIRCRAFT WAS MFG. IN 1979.
