## Discrepancy

TWO HOURS AFTER TAKEOFF, A HEAVY ELECTRICAL ODOR AND SMELL WAS NOTICED BY THE CREW IN THE CENTER PEDESTAL AREA.  A PRECAUTIONARY LANDING WAS EXECUTED.  MAINTENANCE FOUND THE SOURCE OF THE SMOKE FROM THE NR 3 IRS COOLING FAN INVERTER.  THE DEFECTIVE INVERTER AND FAN WERE REPLACED AND AN OPERATION CHECK OF THE SYSTEM PERFORMED.  HONEYWELL TECH NEWSLETTER M23-3341-011-00 ADDRESSES THIS PROBLEM AND SUGGESTS REPLACING THIS KIT.  SUBMITTER STATED THE NEW KIT IS NOT ELIGIBLE FOR INSTALLATION ON THIS MODEL AIRCRAFT.
