## Discrepancy

CREW EXPERIENCED A RIGHT ENGINE FIRE WARNING LIGHT ON DEPARTURE. CREW COMPLETED CHECKLIST PROCEDURES WHICH INCLUDED DISCHARGING BOTH ENGINE FIRE BOTTLES. WARNING LIGHT DID NOT EXTINGUISH IMMEDIATELY AFTER DISCHARGING BOTH FIRE BOTTLES. CREW RETURNED TO DEPARTURE AIRPORT. WARNING LIGHT EXTINGUISHED ON ITS OWN AFTER LANDING. THERE WAS NO FIRE. MAINTENANCE IS STILL INVESTIGATING ROOT CAUSE AT TIME OF THE SUBMISSION BUT HAS DETERMINED THAT THERE ARE NO FUEL OR BLEED AIR LEAKS PRESENT. TAIL-CONE FIRE SENSE LOOP IS SUSPECT AT THIS TIME DUE TO INCONSISTENT RESISTANCE READINGS.
