## Discrepancy

PDX - FLIGHT 2318 - AFTER STARTING DESCENT, THE CREW RAN THE EMERGENCY CHECKLIST AFTER THE NR 2 BLEED HOT CAUTION LIGHT ILLUMINATED.  MAINTENANCE INSPECTED THE AIRCRAFT AND REPLACED THE NUMBER 2 NACELLE DUCT LEAK OVERTEMP SWITCH.  OPERATIONAL CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
