## Discrepancy

PILOT WAS IN FLIGHT TO REFUEL AFTER A CALL.  DURING FLIGHT HE OBSERVED THE NR 1 ENG FIRE WARNING LIGHT FLICKERING INTERMITTENTLY AND PROCEEDED TO LAND AT THE BASE. AFTER RECEIVING THE CALL-OUT,  RESPONDED TO THE BASE AND STARTED TROUBLESHOOTING FOR A FAULTY FIRE INDICATION.  FOUND A BROKEN WIRE FOR THE NR 1 ENGINE FIRE LOOP AT THE AFT FIREWALL AND REPLACED IT.  AFTER REPLACING THE BROKEN WIRE, HAD THE PILOT PERFORM A GROUND RUN AND HOVER CHECK TO DO AN OPS CHECK OF THE SYS AND FOUND NO FURTHER DEFECTS OR FIRE INDICATIONS.  ACFT WAS APPROVED FOR RETURN TO SERVICE AT THAT TIME.
