Narrative:
#3 fire warning sounded and light came on. Silenced bell and retarded throttle. Light went out. Did not shut down engine, restored power, all indications normal. Continued to sju. Had maintenance check engine and found no problems. No logbook entry was made. Departed sju, on climb out problem re-occurred. Retarded throttle and light went out. After approximately 1 min restored power, all temperatures and pressures were normal. Continued to destination. I felt there was a duct leak and was no threat to safety. On third takeoff there were no warnings and engine functioned normally. Upon return to base a log item was made and corrective action was taken. A small crack in a duct was found and repaired.
