## Discrepancy

WHILE PERFORMING INSPECTION ON AIRCRAFT, FOUND RT EXHAUST TRANSMISSION TEE BLISTERED.  UPON REMOVAL, FOUND PERFORATION AT THE BLISTERS.  THESE PIPES ARE MADE OF FAIRLY THICK MATERIAL.  PROBABLY CAUSED BY EROSION IN ADDITION TO EXCESSIVE HEAT.  SUBMITTER STATES THE TIT INDICATION SYSTEM SHOULD BE CHECKED FOR ACCURACY ON A REGULAR BASIS.  CLOSE ATTENTION ALSO NEEDS TO BE PAID TO EXHAUST SYSTEMS.  SHOULD BE INSPECTED AT EVERY OIL CHANGE.
