Narrative:

After landing in btr, ground reported smoke trailing from our #2 engine. Cockpit instrument revealed no unusual indications. We were puzzled by the call because we had already shut down #2 engine as per company policy. As we approached the gate, the ground controller reported smoke coming from the left engine and that smoke was intensifying. As we approached the gate, the egt on the #1 engine began to increase, approaching the ground idle limit. Since we were only about 15 ft from the gate, the captain elected to shut down the left engine and switched on emergency power, thus ensuring we had radio contact. After completing the shutdown checklists, the captain directed me to visually inspect the #1 engine. It was smoking extensively from both the front and back. The fire chief was on scene and asked me if I wanted the fire trucks to respond. Although there was no indication of fire or continued problem, I elected to have the fire trucks respond. I believed that it would be safer to have the trucks in the area -- better to err on the safe side. There was no emergency evacuate/evacuation and no further incident. The problem turned out to be a failure of the #6 bearing -- dumping oil into the hot section of the engine.

Narrative: AFTER LNDG IN BTR, GND RPTED SMOKE TRAILING FROM OUR #2 ENG. COCKPIT INST REVEALED NO UNUSUAL INDICATIONS. WE WERE PUZZLED BY THE CALL BECAUSE WE HAD ALREADY SHUT DOWN #2 ENG AS PER COMPANY POLICY. AS WE APCHED THE GATE, THE GND CTLR RPTED SMOKE COMING FROM THE L ENG AND THAT SMOKE WAS INTENSIFYING. AS WE APCHED THE GATE, THE EGT ON THE #1 ENG BEGAN TO INCREASE, APCHING THE GND IDLE LIMIT. SINCE WE WERE ONLY ABOUT 15 FT FROM THE GATE, THE CAPT ELECTED TO SHUT DOWN THE L ENG AND SWITCHED ON EMER PWR, THUS ENSURING WE HAD RADIO CONTACT. AFTER COMPLETING THE SHUTDOWN CHKLISTS, THE CAPT DIRECTED ME TO VISUALLY INSPECT THE #1 ENG. IT WAS SMOKING EXTENSIVELY FROM BOTH THE FRONT AND BACK. THE FIRE CHIEF WAS ON SCENE AND ASKED ME IF I WANTED THE FIRE TRUCKS TO RESPOND. ALTHOUGH THERE WAS NO INDICATION OF FIRE OR CONTINUED PROB, I ELECTED TO HAVE THE FIRE TRUCKS RESPOND. I BELIEVED THAT IT WOULD BE SAFER TO HAVE THE TRUCKS IN THE AREA -- BETTER TO ERR ON THE SAFE SIDE. THERE WAS NO EMER EVAC AND NO FURTHER INCIDENT. THE PROB TURNED OUT TO BE A FAILURE OF THE #6 BEARING -- DUMPING OIL INTO THE HOT SECTION OF THE ENG.
