Narrative:

In level flight at FL310, a sudden jolt was experienced. We noticed that the left hand EPR, N1, and N2 were surging with egt blank. Within 2-3 seconds, smoke filled the cockpit. We donned our oxygen masks, declared an emergency and initiated an emergency descent. I noticed that the left engine was still producing thrust. Therefore, I was reluctant to shut down the working left engine due to multiple emergencys occurring at that time, ie, smoke, possible fire of an unknown source, and ATC communication difficulty. The L1 flight attendant came to the cockpit to report that smoke had filled the cabin. I told her to prepare for an emergency landing. I also made a PA announcement informing the passenger and crew that we would be landing in about 10 mins. We initially intended to proceed toward mci but I noticed that we were about 80 mi from the airport, so I informed the controller that we needed vectors to the nearest suitable airport. The controller stated that ZZZ was about 20 mi away, so I agreed to be vectored towards the base. We continued to descend on radar vectors, and about 7-10 mi from the airport we gained sight of runway 19. I entered into an approach slot for landing and reduced speed. I was aware that the landing would be overweight, therefore, I smoothly landed the aircraft and applied right reverse thrust with minimum braking to avoid tire damage or brake overheat. Once stopped, the brakes were set and I then called for the evacuate/evacuation checklist, and informed the L1 flight attendant to initiate an evacuate/evacuation from the right side only. I then made a PA announcement reinforcing the evacuate/evacuation command and asked the passenger to remain calm but quickly move to the emergency exits. I then assisted with the evacuate/evacuation and was the last person to leave the aircraft through the right overwing exit. The crew then directed the passenger away from the aircraft to a safe distance.

Title: MD80 CREW HAD A MALFUNCTION ENG AND CABIN AND COCKPIT SMOKE IN ZKC CLASS A AIRSPACE.

Narrative: IN LEVEL FLT AT FL310, A SUDDEN JOLT WAS EXPERIENCED. WE NOTICED THAT THE L HAND EPR, N1, AND N2 WERE SURGING WITH EGT BLANK. WITHIN 2-3 SECONDS, SMOKE FILLED THE COCKPIT. WE DONNED OUR OXYGEN MASKS, DECLARED AN EMER AND INITIATED AN EMER DSCNT. I NOTICED THAT THE L ENG WAS STILL PRODUCING THRUST. THEREFORE, I WAS RELUCTANT TO SHUT DOWN THE WORKING L ENG DUE TO MULTIPLE EMERS OCCURRING AT THAT TIME, IE, SMOKE, POSSIBLE FIRE OF AN UNKNOWN SOURCE, AND ATC COM DIFFICULTY. THE L1 FLT ATTENDANT CAME TO THE COCKPIT TO RPT THAT SMOKE HAD FILLED THE CABIN. I TOLD HER TO PREPARE FOR AN EMER LNDG. I ALSO MADE A PA ANNOUNCEMENT INFORMING THE PAX AND CREW THAT WE WOULD BE LNDG IN ABOUT 10 MINS. WE INITIALLY INTENDED TO PROCEED TOWARD MCI BUT I NOTICED THAT WE WERE ABOUT 80 MI FROM THE ARPT, SO I INFORMED THE CTLR THAT WE NEEDED VECTORS TO THE NEAREST SUITABLE ARPT. THE CTLR STATED THAT ZZZ WAS ABOUT 20 MI AWAY, SO I AGREED TO BE VECTORED TOWARDS THE BASE. WE CONTINUED TO DSND ON RADAR VECTORS, AND ABOUT 7-10 MI FROM THE ARPT WE GAINED SIGHT OF RWY 19. I ENTERED INTO AN APCH SLOT FOR LNDG AND REDUCED SPD. I WAS AWARE THAT THE LNDG WOULD BE OVERWT, THEREFORE, I SMOOTHLY LANDED THE ACFT AND APPLIED R REVERSE THRUST WITH MINIMUM BRAKING TO AVOID TIRE DAMAGE OR BRAKE OVERHEAT. ONCE STOPPED, THE BRAKES WERE SET AND I THEN CALLED FOR THE EVAC CHKLIST, AND INFORMED THE L1 FLT ATTENDANT TO INITIATE AN EVAC FROM THE R SIDE ONLY. I THEN MADE A PA ANNOUNCEMENT REINFORCING THE EVAC COMMAND AND ASKED THE PAX TO REMAIN CALM BUT QUICKLY MOVE TO THE EMER EXITS. I THEN ASSISTED WITH THE EVAC AND WAS THE LAST PERSON TO LEAVE THE ACFT THROUGH THE R OVERWING EXIT. THE CREW THEN DIRECTED THE PAX AWAY FROM THE ACFT TO A SAFE DISTANCE.
