## Discrepancy

AFTER LEVELING OFF AT 5000 FT THE NO 1 FIRE DET LIGHT IS ILLUMINATED. WE
VERIFIED THERE WERE NO INSTRUMENT INDICATIONS OF A FIRE IN THE NO 1 ENGINE
AND CONSULTED THE QRH. AFTER NOTING THERE WAS NO IMMEDIATE DANGER WE
TURNED THE AIRCRAFT TO OGLE AND COMPLETED A NORMAL LANDING WITHOUT INCIDENT
