AT THE BEGINNING OF A FLIGHT, JUST AFTER TAKEOFF, THE FIRE WARNING LIGHT ILLUMINATED FOR THE NUMBER 3 ENGINE. THE FLIGHT CREW PERFORMED THE APPROPRIATE EMERGENCY PROCEDURES AND RETURNED FOR LANDING. AFTER LANDING, FIRE CREWS EXTINGUISHED THE STILL BURNING FIRE THAT WAS CONFINED TO THE ENGINE COMPARTMENT. INSPECTION OF THE ENGINE REVEALED THAT THE STARTER EXPERIENCED AN INFLIGHT FAILURE. THE STARTER CONTROL VALVE WAS EXAMINED AND FOUND TO OPERATE NORMALLY AT THE TIME OF THE INSPECTION.
