Narrative:

Departed lax for mem in an large transport. Just prior to level off at FL370 the first officer noticed right engine egt rising toward red line. Right engine throttle was reduced to keep egt in normal range. Approximately 2-3 mins later, smoke entered aircraft through the air conditioning system rapidly. I elected to turn off the right air conditioning pack since there was an obvious problem with the engine. This was contrary to emergency procedure but it stopped the smoke! Diversion was made into las with an over weight landing at 200000 pounds (emergency declared). Normal landing was made. On inspection of engine, they found metal particles in tail pipe and oil leak in fan section. Engine was changed. 2-MAN cockpit makes workload very high in this type situation and difficult to find time to talk to passenger. Emergency procedure for smoke does not seem to deal with this type engine problem. Supplemental information from acn 237520: within a min or 2 the lead flight attendant came to the cockpit and told us there was smoke in the cabin. I also told the controller we had smoke in the cabin. We also had our jump seat rider go back in the cabin. He verified the smoke, and now said it was starting to clear. On the descent we finally declared an emergency. Landing was normal. 2 things stand out for me. 1) we should have declared an emergency right away. 2) I'm amazed how quickly I became overloaded. While the captain was talking to the company I had to fly the airplane, program the computer to go to las and talk to ATC. It all worked out, and no one was hurt, although with only 2 guys in the cockpit, it's easy to get overloaded.

Narrative: DEPARTED LAX FOR MEM IN AN LGT. JUST PRIOR TO LEVEL OFF AT FL370 THE FO NOTICED R ENG EGT RISING TOWARD RED LINE. R ENG THROTTLE WAS REDUCED TO KEEP EGT IN NORMAL RANGE. APPROX 2-3 MINS LATER, SMOKE ENTERED ACFT THROUGH THE AIR CONDITIONING SYS RAPIDLY. I ELECTED TO TURN OFF THE R AIR CONDITIONING PACK SINCE THERE WAS AN OBVIOUS PROB WITH THE ENG. THIS WAS CONTRARY TO EMER PROC BUT IT STOPPED THE SMOKE! DIVERSION WAS MADE INTO LAS WITH AN OVER WT LNDG AT 200000 LBS (EMER DECLARED). NORMAL LNDG WAS MADE. ON INSPECTION OF ENG, THEY FOUND METAL PARTICLES IN TAIL PIPE AND OIL LEAK IN FAN SECTION. ENG WAS CHANGED. 2-MAN COCKPIT MAKES WORKLOAD VERY HIGH IN THIS TYPE SIT AND DIFFICULT TO FIND TIME TO TALK TO PAX. EMER PROC FOR SMOKE DOES NOT SEEM TO DEAL WITH THIS TYPE ENG PROB. SUPPLEMENTAL INFO FROM ACN 237520: WITHIN A MIN OR 2 THE LEAD FLT ATTENDANT CAME TO THE COCKPIT AND TOLD US THERE WAS SMOKE IN THE CABIN. I ALSO TOLD THE CTLR WE HAD SMOKE IN THE CABIN. WE ALSO HAD OUR JUMP SEAT RIDER GO BACK IN THE CABIN. HE VERIFIED THE SMOKE, AND NOW SAID IT WAS STARTING TO CLR. ON THE DSCNT WE FINALLY DECLARED AN EMER. LNDG WAS NORMAL. 2 THINGS STAND OUT FOR ME. 1) WE SHOULD HAVE DECLARED AN EMER RIGHT AWAY. 2) I'M AMAZED HOW QUICKLY I BECAME OVERLOADED. WHILE THE CAPT WAS TALKING TO THE COMPANY I HAD TO FLY THE AIRPLANE, PROGRAM THE COMPUTER TO GO TO LAS AND TALK TO ATC. IT ALL WORKED OUT, AND NO ONE WAS HURT, ALTHOUGH WITH ONLY 2 GUYS IN THE COCKPIT, IT'S EASY TO GET OVERLOADED.
