## Discrepancy

PILOT REPORTED FATIGUE WHILE FLYING. NO OBVIOUS EXTERNAL SIGNS OF MUFFLER FAILURE WERE FOUND, SHROUD REMOVAL REVEALED A TIGHT CRACK FROM NR 2 RISER INTO BODY, 3 INCHES LONG THAT LEFT VERY LITTLE STAINING ON INSIDE OF SHROUD. MUFFLER BODY WAS DEFORMED WHERE RISER IS WELDED INTO BODY, NEW MUFFLER HAD NO DEFORMATION IN THIS AREA.
