## Discrepancy

(CAN) DURING AN INSPECTION OF THE LT ENGINE FOR ROUGHNESS, A VISUAL INSPECTION WAS CARRIED OUT ON THE RT ENGINE.  WHEN THE EXHAUST TAILPIPE WAS INSPECTED IT WAS FOUND TO BE BLOCKED.  THE MUFFLER WAS REMOVED FOR THE AFT NR 3 AND NR 4 CYLINDERS ON THE RT ENGINE.  THE INTERNAL PIPE WAS FOUND TO BE BROKEN FROM THE END PIECES.  ABOUT 4" OF IT WAS LODGED IN THE TAILPIPE.  A LARGE AMOUNT OF THE INTERNAL PIPE APPEARS TO BE MISSING FROM THE MUFFLER ALSO.
