## Discrepancy

UPON ANNUAL INSPECTION, REMOVAL OF EXHAUST SHROUD FOUND MUFFLER CRACKED AT POINT WHERE SHROUD CHAFED MUFFLER.  YEAR AFTER YEAR OF REMOVAL AND REINSTALLATION OF SHROUD TO MUFFLERS FINALLY WORE MUFFLER MATERIAL THIN ENOUGH TO CRACK AND LEAK.  SUBMITTER SUGGESTS THOROUGH INSPECTION EACH TIME SHROUD REMOVED (ANYTIME) ESPECIALLY AT CLAMP POINTS.
