## Discrepancy

(CAN) AT EXHAUST PORT, THE FLANGE THAT PROTRUDES OUT OF THE CASE TO PREVENT EXHAUST GASES FROM EXITING THROUGH THE FLANGE WHERE THE EXHAUST STACK BOLTS ON, WAS CRACKED ABOUT 320 DEGREES AROUND THE CIRCUMFERENCE. THE OPPOSITE PORT WAS DETERMINED TO BE CRACKED TO A LESSOR AMOUNT.  THE EXHAUST FLANGE ON THE EXHAUST DUCT ITSELF WAS SERVICEABLE.
