## Discrepancy

(CAN) AFTER THE ENGINE SHUTDOWN , THE RE-FUELER SAW SMOKE COMING OUT FROM ONE OF THE DE-ICER BOOTS ON THE NR TWO PROPELLER.  HE ADVISED THE CREW ABOUT THE SITUATION.  THE CAPTAIN EXTINGUISHED THE FLAME WHILE THE COPILOT INITIATED THE EMERGENCY PROCEDURE.   MAINTENANCE REPLACED THE NR TWO PROPELLER ASSEMBLY AND THE FOLLOWING PARTS:  K1 RELAY P/N 109-381002; K2 RELAY P/N 24166-D1; AND THE PRESSURE SWITCH KS-9 (P/N 50-389121-51).  SUBMITTER  SUSPECTED K2 RELAY TO BE THE SOURCE OF THE PROBLEM.
