Narrative

WE DEPARTED DEN FOR OMA. CLBING THROUGH FL220; THE SO RPTED AN AMBER LIGHT ON HIS PANEL; THE LOWER AFT BODY OVERHEAT LIGHT HAD ILLUMINATED. I ASKED THE FO TO LEVEL OFF AND INFORM ATC OF THE PROB AND ASKED THE SO TO RUN THE 'LOWER AFT BODY OVERHEAT' CHKLIST. I RETARDED THE #2 THROTTLE TO IDLE. THE FLT ATTENDANT CAME TO THE COCKPIT TO INFORM US THAT THE CABIN WAS VERY HOT AND HAD A BURNING ODOR. WE NOTICED THAT THE #2 ENG OIL TEMP WAS STEADILY INCREASING AND APCHING THE RED LINE. WE SHUT DOWN THE #2 ENG AND DECLARED AN EMER. WE BEGAN AN INITIAL DSCNT FOR DEN. DURING THE DSCNT; WHILE RUNNING THE ENG SHUTDOWN CHKLIST AND #2 ENG APCH AND LNDG CHKLIST; WE ASKED ATC FOR THE NEAREST ARPT. THEY STATED THAT WE WERE JUST ABOUT OVERHEAD AKRON; CO. WE ASKED THE RWY LENGTH; THEY RPTED 7000 FT. WE DECIDED TO LAND IN AKRON. I MADE A PA ANNOUNCEMENT TO INFORM THE PAX AND FLT ATTENDANTS THAT WE KNEW THE ACFT WAS HOT AND HAD A BURNING ODOR AND THAT WE WOULD BE ON THE GND ASAP. WE CONTINUED DSCNT; BRIEFED THE SINGLE ENG GAR PROC AND SET THE LNDG BUGS FOR THE AIRSPD INDICATORS. I THEN ASSUMED THE DUTIES OF PF; AND LANDED ON RWY 11. WE STOPPED THE ACFT AT THE FAR END OF THE RWY IN VIEW OF THE EMER EQUIP. THEY INFORMED US THAT THERE WAS NO VISIBLE SMOKE OR FIRE. WE TAXIED TO THE RAMP AREA AND SECURED THE ACFT. AFTER INSPECTION OF THE AFT AIRSTAIR AREA; THE PAX AND CARGO WERE DEPLANED. SUPPLEMENTAL INFO FROM ACN 407804: THE #2 OIL TEMP WAS CLBING RAPIDLY TOWARD RED LINE. WE SHUT DOWN ENG #2. THE OVERHEAT LIGHT STAYED ON. AS WE STARTED THE OVERHEAT CHKLIST TOP ITEM (LAND AT NEAREST SUITABLE ARPT) SINCE THE LIGHT STAYED ON AND WE ALSO SHUT #2 ENG DOWN; IT WAS DETERMINED TO LAND AT AKO. AN EMER WAS DECLARED; AND DSCNT WAS BEING DONE. IT WAS DETERMINED WE NEEDED TO RUN THE INFLT ENG SHUTDOWN; 2 GENERATOR OPS/2 ENG LNDG CHKLISTS FIRST. WE LANDED AND DID NOT EVAC THE PLANE SINCE THE OVERHEAT LIGHT WENT OUT ON FINAL. CALLBACK CONVERSATION WITH RPTR ACN #407801 REVEALED THE FOLLOWING INFO: MAINT FOUND LEAKING PNEUMATIC FLEX DUCTS; A #2 ENG 13TH STAGE BLEED THAT WAS NOT CLOSING PROPERLY; A R PACK COOLING FAN THAT WAS RUNNING BACKWARDS; AND AN AIR OIL HEAT EXCHANGER ON #2 ENG THAT HAD TO BE REPLACED. PAX AND CREW WERE RETURNED TO DEN BY BUS.
