## Discrepancy

FOUND FUEL DRAIN ON LEFT WING WITH CENTER PIECE, THAT PUSHES UP TO DRAIN FUEL, HANGING DOWN APPROXIMATELY .1250 INCH.  REMOVED VALVE AND FOUND SEVERELY CORRODED INSIDE ALLOWING CENTER PIECE WHICH IS SPRING LOADED TO GO BEYOND ITS INTERNAL STOPS.  IF NOT CORRECTED, DRAIN COULD CAUSE LARGE AMOUNTS OF FUEL TO LEAK OUT.  (NOTE:  CENTER PIECE WAS CORRODED ONE-FOURTH WAY THROUGH).
