## Discrepancy

AFTER NOTING A HYDRAULIC LEAK BY THE RT MAIN GEAR WHEEL WELL, FOUND ALUMINUM HYDRAULIC LINE FOR THE FLAP RETURN SYSTEM WEEPING FROM A CORROSION PIN HOLE.  THE PIN HOLE IS APPROXIMATELY 1 INCH FROM END OF LINE AND IN THE MIDDLE OF A 90 DEGREE BEND.  THE LINE IS DATED 1-30-81, AND LOOKS TO BE ORIGINAL.  THE LINE IS PAINTED WITH ZINC CHROMATE INCLUDING THE AREA WITH THE PIN HOLE.  NEW LINE WAS INSTALLED.
