## Discrepancy

(CAN) DURING A ROUTINE INSPECTION, AME NOTICED AN OILY STREAK ON THE FITTING. AFTER CLEANING, IT APPEARED TO BE A DEEP SCRATCH. THE AREA WAS CLEANED WITH SOLVENT AND REEXAMINED, WHICH LOOKED LIKE A CRACK. AN NDT. (LIQUID PENETRANT) WAS PERFORMED TO CONFIRM THE CRACK. IT WAS ESTABLISHED THAT IT WAS A CRACK.A FLEET-WIDE INSPECTION WAS PERFORMED ON ALL FITTINGS. NO DEFECTS WERE FOUND. THE MANUFACTURER WAS INFORMED AND PROBLEM WAS DISCUSSED AT LENGTH. AWAITING PARTS FOR REPLACEMENT.
