## Discrepancy

DURING AN EVENT 2 INSPECTION, THE AIR CONDITIONING SYSTEM WAS BEING SERVICED WITH FREON R-12 DUE TO LOW OUTPUT.  AFTER SERVICING, A LEAK WAS FOUND ON THE LOW PRESSURE SIDE IN THE RIGHT WING LEADING EDGE. UNABLE TO STOP LEAK BY TIGHTENING B-NUT.  EVACUATED SYSTEM AND REMOVED LINE FOR INSPECTION.  THE FLARE WAS FOUND HEAVILY CORRODED WITH A HOLE THROUGH IT. REPLACED LINE, LEAK CHECK SATISFACTORY.  LINE IS LOWEST POINT IN SYSTEM.
