## Discrepancy

(CAN) ORIGINAL SNAG WAS CHAFING AT TUBE WHERE IT ATTACHES TO EXHAUST STACK.  A WEEK LATER FOLLOWING INSTALLATION OF NEW PART, TUBES WERE FOUND TO BE CRACKED INBETWEEN PLEATS OF FLEX TUBE.  ON ONE TUBE, MATERIAL WAS MISSING AND SIGNIFICANT AMOUNT OF EXHAUST WAS LEAKING INTO COWL AREA.  NO SIGN OF OVERHEATING.  REPLACED TUBES WITH NEW GASKETS.  SUBMITTER STATED COMMUTER AIR TRANSPORT REPORTS THIS IS COMMON.
