## Discrepancy

START DRAIN VALVE FAILED INTERNALLY ALLOWING FUEL TO FLOW INTO THE COMPRESSOR THROUGH THE P2 AIR LINE.  FUEL BLEW OUT OF THE COMPRESSOR CASE SPLIT LINE AND IGNITED ON TOP OF THE ENGINE CAUSING THE FIRE WARNING LIGHT TO FLICKER ON AND OFF SEVERAL TIMES.  PILOT RETURNED TO DEPARTURE PAD AND LANDED SAFELY WITH BOTH ENGINES OPERATING AND PERFORMED AN EMERGENCY SHUTDOWN OF BOTH ENGINES.  FIRE WARNING LIGHT HAD GONE OUT AND THE FIRE SELF EXTINGUISHED.  THE FIRE BOTTLES WERE NOT DISCHARGED.  NO DAMAGE FOUND TO THE COWLING OR IN THE ENGINE COMPARTMENT.
