Narrative:
After a normal takeoff and level off at FL350, we heard a loud bang. The aircraft began to shake. At first, we could not determine what was wrong because all engine instruments looked normal, however we saw a few annunciator lights that indicated we had some kind of problem with the right engine. Just a few mins later, one of our cabin crew informed us of a fire in our right engine. We never had a fire light, but we took her word for it. We declared an emergency and started a descent for austin. We started a turn while running our checklist. We then noticed that smoke was coming from the eyeball outlets so we then turned off the right air conditioning pack. After approximately 2-3 mins, the smoke cleared. We shut down the right engine and fired both bottles of extinguisher. We continued the descent into austin and landed. All equipment was standing by upon landing. We cleared the runway (31L) after being checked out by the fire trucks. They said there was no fire, but fuel was leaking from the engine. We taxied a little further and decided to stop and evacuate/evacuation the aircraft. All passenger were evacuate/evacuationed safely. Supplemental information from acn 257542: during taxi-in, informed by fire trucks and tower fuel 'pouring from #2 engine.' fire department recommended evacuate/evacuation. Captain informed flight attendants of fuel leaking on the #2 engine and ordered an orderly evacuate/evacuation out both forward doors. Evacuate/evacuation was orderly. No injuries noted. All appropriate checklists accomplished. Informed by maintenance after incident that #3 stage compressor threw a blade which caused the problem. Also, engine anti-ice cowl around lip of engine was blown off. Callback conversation with reporter revealed the following information: maintenance advised reporter that a compressor blade and a fan blade had departed wiping out the front of the engine including the main wiring harness. This may account for the lack of a fire warning light. Also, the fuel leak reported by the fire department was apparently just residual fuel running from the lines downstream of the firewall shutoff. The valve seemed to work fine. By the time the flight crew finished the evacuate/evacuation checklist and looked back, the cabin attendants had evacuate/evacuationed all 103 passenger and had left the aircraft themselves.

Title: MLG DIVERTED TO AUS WHEN THEY HAD A CATASTROPHIC FAILURE OF THE R ENG FOLLOWED BY A FIRE.
Narrative: AFTER A NORMAL TKOF AND LEVEL OFF AT FL350, WE HEARD A LOUD BANG. THE ACFT BEGAN TO SHAKE. AT FIRST, WE COULD NOT DETERMINE WHAT WAS WRONG BECAUSE ALL ENG INSTS LOOKED NORMAL, HOWEVER WE SAW A FEW ANNUNCIATOR LIGHTS THAT INDICATED WE HAD SOME KIND OF PROB WITH THE R ENG. JUST A FEW MINS LATER, ONE OF OUR CABIN CREW INFORMED US OF A FIRE IN OUR R ENG. WE NEVER HAD A FIRE LIGHT, BUT WE TOOK HER WORD FOR IT. WE DECLARED AN EMER AND STARTED A DSCNT FOR AUSTIN. WE STARTED A TURN WHILE RUNNING OUR CHKLIST. WE THEN NOTICED THAT SMOKE WAS COMING FROM THE EYEBALL OUTLETS SO WE THEN TURNED OFF THE R AIR CONDITIONING PACK. AFTER APPROX 2-3 MINS, THE SMOKE CLRED. WE SHUT DOWN THE R ENG AND FIRED BOTH BOTTLES OF EXTINGUISHER. WE CONTINUED THE DSCNT INTO AUSTIN AND LANDED. ALL EQUIP WAS STANDING BY UPON LNDG. WE CLRED THE RWY (31L) AFTER BEING CHKED OUT BY THE FIRE TRUCKS. THEY SAID THERE WAS NO FIRE, BUT FUEL WAS LEAKING FROM THE ENG. WE TAXIED A LITTLE FURTHER AND DECIDED TO STOP AND EVAC THE ACFT. ALL PAX WERE EVACED SAFELY. SUPPLEMENTAL INFO FROM ACN 257542: DURING TAXI-IN, INFORMED BY FIRE TRUCKS AND TWR FUEL 'POURING FROM #2 ENG.' FIRE DEPT RECOMMENDED EVAC. CAPT INFORMED FLT ATTENDANTS OF FUEL LEAKING ON THE #2 ENG AND ORDERED AN ORDERLY EVAC OUT BOTH FORWARD DOORS. EVAC WAS ORDERLY. NO INJURIES NOTED. ALL APPROPRIATE CHKLISTS ACCOMPLISHED. INFORMED BY MAINT AFTER INCIDENT THAT #3 STAGE COMPRESSOR THREW A BLADE WHICH CAUSED THE PROB. ALSO, ENG ANTI-ICE COWL AROUND LIP OF ENG WAS BLOWN OFF. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: MAINT ADVISED RPTR THAT A COMPRESSOR BLADE AND A FAN BLADE HAD DEPARTED WIPING OUT THE FRONT OF THE ENG INCLUDING THE MAIN WIRING HARNESS. THIS MAY ACCOUNT FOR THE LACK OF A FIRE WARNING LIGHT. ALSO, THE FUEL LEAK RPTED BY THE FIRE DEPT WAS APPARENTLY JUST RESIDUAL FUEL RUNNING FROM THE LINES DOWNSTREAM OF THE FIREWALL SHUTOFF. THE VALVE SEEMED TO WORK FINE. BY THE TIME THE FLC FINISHED THE EVAC CHKLIST AND LOOKED BACK, THE CABIN ATTENDANTS HAD EVACED ALL 103 PAX AND HAD LEFT THE ACFT THEMSELVES.
