## Discrepancy

CABIN HEAT DUCT TUBING LEADING FROM THE FIREWALL TO THE REAR SEAT HEAT IS CAUSING SEVERE CORROSION IN THE CABIN TUNNEL INTERIOR.  THIS TUNNEL SUPPORTS THE YOKE ASSEMBLY, TRIM WHEEL, AND FLAP LEVER.  RECOMMEND REPLACING ALL INTERIOR DUCT TUBING WITH MODERN SILICONE CAT OR SCAT, INSPECT FOR CORROSION.
