Narrative:

We received a right 'bleed closed' light illumination. We went to the QRH and reset it (bleed fault checklist). We noted that the left duct temperature indication was maintaining 25 degrees C; normal for the cruise altitude of 17000 ft. The flight attendant called about this time and notified us the temperature in the cabin was warm; so we selected a cold setting on the automatic temperature control and nothing changed. The right bleed failed again (right bleed closed light illuminated). We reset it. According to the QRH 2 attempts are allowed. We also switched from automatic to manual temperature control and held switches to full cold with no change. Left duct temperature was indicating maintaining 25 degrees C. Just prior to descent; right bleed valve closed again. We did not reset and temperature rose to about 30 degrees C; but since the power was brought back a little; I thought it was normal. I contacted maintenance control notifying them of the bleed failure and asked them if there was any other concerns and told them that left duct temperature was maintaining 25 degrees C and would not come down in manual or automatic. At leveloff at 8000 ft; as power was increased; left duct temperature rose rapidly above 40 degrees C. I tried to manually select cold but temperature indication continued to rise. QRH says to 'consider engine shutdown' if unable to control temperature. I discussed with my first officer and we elected to comply with the QRH. I completed the engine shutdown. As power was increased on the left engine for the engine shutdown; temperature in the left duct was well above 50 degrees C. When right engine was shut down; left duct temperature fell rapidly to 15 degrees C and fluctuated between 15 degrees C and 25 degrees C; depending on the power setting; very normal. Also; I cycled manual temperature control briefly and left duct temperature indication fluctuated normally. Prior to the shutdown of the right engine; I was unable to get any response with the temperature control. Callback conversation with reporter revealed the following information: the reporter stated they were within 11 miles of destination; so they continued to their scheduled destination. No emergency was declared; since the tower told them crash fire rescue equipment equipment was already standing by.

Title: AN SF340B FLT CREW GOT A 'BLEED CLOSED' LIGHT AND WERE UNABLE TO CONTROL DUCT TEMP. THEY FOLLOWED QRC THAT RESULTED IN INFLT ENG SHUTDOWN.

Narrative: WE RECEIVED A R 'BLEED CLOSED' LIGHT ILLUMINATION. WE WENT TO THE QRH AND RESET IT (BLEED FAULT CHKLIST). WE NOTED THAT THE L DUCT TEMP INDICATION WAS MAINTAINING 25 DEGS C; NORMAL FOR THE CRUISE ALT OF 17000 FT. THE FLT ATTENDANT CALLED ABOUT THIS TIME AND NOTIFIED US THE TEMP IN THE CABIN WAS WARM; SO WE SELECTED A COLD SETTING ON THE AUTO TEMP CTL AND NOTHING CHANGED. THE R BLEED FAILED AGAIN (R BLEED CLOSED LIGHT ILLUMINATED). WE RESET IT. ACCORDING TO THE QRH 2 ATTEMPTS ARE ALLOWED. WE ALSO SWITCHED FROM AUTO TO MANUAL TEMP CTL AND HELD SWITCHES TO FULL COLD WITH NO CHANGE. L DUCT TEMP WAS INDICATING MAINTAINING 25 DEGS C. JUST PRIOR TO DSCNT; R BLEED VALVE CLOSED AGAIN. WE DID NOT RESET AND TEMP ROSE TO ABOUT 30 DEGS C; BUT SINCE THE PWR WAS BROUGHT BACK A LITTLE; I THOUGHT IT WAS NORMAL. I CONTACTED MAINT CTL NOTIFYING THEM OF THE BLEED FAILURE AND ASKED THEM IF THERE WAS ANY OTHER CONCERNS AND TOLD THEM THAT L DUCT TEMP WAS MAINTAINING 25 DEGS C AND WOULD NOT COME DOWN IN MANUAL OR AUTO. AT LEVELOFF AT 8000 FT; AS PWR WAS INCREASED; L DUCT TEMP ROSE RAPIDLY ABOVE 40 DEGS C. I TRIED TO MANUALLY SELECT COLD BUT TEMP INDICATION CONTINUED TO RISE. QRH SAYS TO 'CONSIDER ENG SHUTDOWN' IF UNABLE TO CTL TEMP. I DISCUSSED WITH MY FO AND WE ELECTED TO COMPLY WITH THE QRH. I COMPLETED THE ENG SHUTDOWN. AS PWR WAS INCREASED ON THE L ENG FOR THE ENG SHUTDOWN; TEMP IN THE L DUCT WAS WELL ABOVE 50 DEGS C. WHEN R ENG WAS SHUT DOWN; L DUCT TEMP FELL RAPIDLY TO 15 DEGS C AND FLUCTUATED BTWN 15 DEGS C AND 25 DEGS C; DEPENDING ON THE PWR SETTING; VERY NORMAL. ALSO; I CYCLED MANUAL TEMP CTL BRIEFLY AND L DUCT TEMP INDICATION FLUCTUATED NORMALLY. PRIOR TO THE SHUTDOWN OF THE R ENG; I WAS UNABLE TO GET ANY RESPONSE WITH THE TEMP CTL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE REPORTER STATED THEY WERE WITHIN 11 MILES OF DESTINATION; SO THEY CONTINUED TO THEIR SCHEDULED DESTINATION. NO EMERGENCY WAS DECLARED; SINCE THE TOWER TOLD THEM CFR EQUIPMENT WAS ALREADY STANDING BY.
