Narrative:

On climb out at las approximately 3 min after takeoff, the #3 engine fire light illuminated and fire warning bell sounded. (Aircraft weight 175000 pounds). We had just retracted the flaps to 0 degree. We followed the shut down procedure as written in our standard operating procedures, however, the fire light remained illuminated. We elected to dump as much fuel as practical, with our primary concern being to get the aircraft on the ground for passenger safety. Consequently we dumped until 4 mi final, a total of approximately 15000 pounds was dumped. Due to the apparent very serious nature of our predicament we elected to land overweight at 161000 pounds. (At all time we had the tower observe our aircraft for any indication of fire, no fire was evident throughout our ordeal). We had a smooth T/D under 200 FPM rate of sink on ground contact. The fire equipment followed our aircraft to the gate, after inspection upon T/D. We had decided that we would evacuate the aircraft on the runway if any visibility sign of fire was reported. We told the tower to 'constantly observe' and 'immediately report' any evidence of fire. F/as were notified to 'standby for evacuation'. All crew members function in a very cool professional manner. The total time from fire warning to T/D was 6 to 7 mins. Observations: it was difficult and time consuming trying to get the safety pin out of the fuel shut off switch guard. Second officer had to pry it with a screwdriver.

Title: ENGINE FIRE INDICATION FOR ACR LGT AFTER TKOF AT LAS, EMERGENCY LNDG.

Narrative: ON CLBOUT AT LAS APPROX 3 MIN AFTER TKOF, THE #3 ENG FIRE LIGHT ILLUMINATED AND FIRE WARNING BELL SOUNDED. (ACFT WEIGHT 175000 LBS). WE HAD JUST RETRACTED THE FLAPS TO 0 DEG. WE FOLLOWED THE SHUT DOWN PROC AS WRITTEN IN OUR STANDARD OPERATING PROCS, HOWEVER, THE FIRE LIGHT REMAINED ILLUMINATED. WE ELECTED TO DUMP AS MUCH FUEL AS PRACTICAL, WITH OUR PRIMARY CONCERN BEING TO GET THE ACFT ON THE GND FOR PAX SAFETY. CONSEQUENTLY WE DUMPED UNTIL 4 MI FINAL, A TOTAL OF APPROX 15000 LBS WAS DUMPED. DUE TO THE APPARENT VERY SERIOUS NATURE OF OUR PREDICAMENT WE ELECTED TO LAND OVERWEIGHT AT 161000 LBS. (AT ALL TIME WE HAD THE TWR OBSERVE OUR ACFT FOR ANY INDICATION OF FIRE, NO FIRE WAS EVIDENT THROUGHOUT OUR ORDEAL). WE HAD A SMOOTH T/D UNDER 200 FPM RATE OF SINK ON GND CONTACT. THE FIRE EQUIP FOLLOWED OUR ACFT TO THE GATE, AFTER INSPECTION UPON T/D. WE HAD DECIDED THAT WE WOULD EVACUATE THE ACFT ON THE RWY IF ANY VIS SIGN OF FIRE WAS RPTED. WE TOLD THE TWR TO 'CONSTANTLY OBSERVE' AND 'IMMEDIATELY RPT' ANY EVIDENCE OF FIRE. F/AS WERE NOTIFIED TO 'STANDBY FOR EVACUATION'. ALL CREW MEMBERS FUNCTION IN A VERY COOL PROFESSIONAL MANNER. THE TOTAL TIME FROM FIRE WARNING TO T/D WAS 6 TO 7 MINS. OBSERVATIONS: IT WAS DIFFICULT AND TIME CONSUMING TRYING TO GET THE SAFETY PIN OUT OF THE FUEL SHUT OFF SWITCH GUARD. S/O HAD TO PRY IT WITH A SCREWDRIVER.
