## Discrepancy

AIR TURNBACK.  FLIGHT CREW REPORTED RT WING/BODY OVERHEAT LIGHT ILLUMINATED AND AIRCRAFT WOULD NOT PRESSURIZE.  AIRCRAFT RETURNED TO DEN AND LANDED WITHOUT INCIDENT.  MAINTENANCE PLACARD THE RT PACK INOPERATIVE PER MEL 21-2 AND SUBSEQUENTLY REPLACED DAMAGED DUCT (APPROX 1.5 INCH DIAMETER HOLE WITH CRACKS) UPSTREAM OF THE RT PRIMARY HEAT EXCHANGER.  PERFORMED OPERATIONAL TEST AND SYSTEM CHECKED OKAY.
