## Discrepancy

(CAN) THE PILOT REPORTED AN INTERMITTENT (POPPING) SOUND DURING ALL PHASES OF OPERATION.  MAINTENANCE INVESTIGATION REVEALED A CRACK AND BLOWN EXHAUST GASKET ON NR 3 CYLINDER EXHAUST SEGMENT.  THE CRACK EXTENDED AROUND MOST OF THE FLANGE, AND WAS CREEPING UP THE STUB APPROXIMATELY 1 INCH.  THE SEGMENT WAS WELD REPAIRED AND REINSTALLED.
