## Discrepancy

THIS IS THE SECOND REPORT OF FINDING THE ABOVE COMPONENT DEFECTIVE.  THEY ARE CRACKING BEHIND THE MUFFLER SHROUD AND CANNOT BE SEEN WITHOUT REMOVAL OF THE SHROUD.  THIS ALLOWS EXHAUST GASES TO ENTER THE COCKPIT WHEN THE HEATER IS UTILIZED.  THE CRACK LENGTH IS APPROXIMATELY FIVE TO SIX INCHES.  A PICTURE OF THE CRACKED AREA WILL BE E-MAILED AS WELL.
