## Discrepancy

AFTER TAKE OFF, THE CREW AND PILOT NOTICED AN INEXPLICABLE HEAT RADIATING THROUGH THE AIRCRAFT ACCOMPANIED BY A SMELL OF BURNING PLASTIC. HEATER, AIR CONDITIONER AND DEMISTER WERE IN THE OFF POSITION. WE WERE ONLY A FEW MILES AWAY FROM BASE AND RETURNED TO BASE WITHOUT ISSUE AND CONTACTED MAINTENANCE. UPON INSPECTION BY MAINTENANCE PROBLEM COULD NOT BE DUPLICATED, NO DISCREPANCIES WERE FOUND.
