Narrative:

On this sale demonstration was climbing through 15000 ft MSL on our way to FL230. Left engine quit making power. I proceeded to ask ZMP to return to oma. I also asked for lower, so they allowed me to descend to 11000 ft. During the troubleshooting we tried to level off at 11000 ft and was unable to hold altitude. I requested lower and was turned over to oma approach. As I checked in, I decided it was time to declare an emergency and do a precautionary shutdown of the left engine because of the smell of burning oil in the cockpit. We shut the engine down. I called the airport in sight and approach cleared us for the visual to runway 32L after they asked us what runway we wanted. When we were told to switch frequency and go to tower we acknowledged. Upon switching to tower the controller cleared us for the visual to runway 36. I replied that we wanted runway 32L. Upon landing I thought we would be able to taxi, but the aircraft would not because of excessive power on the right side. We ended up stopped in the intersection of runway 32L and runway 36, holding all traffic until they could get a tug out to tow us off the runway. I probably could have stopped and held short of runway 36. I was more worried about getting us down than I was about inconveniencing an airline flight. Callback conversation with reporter revealed the following information: the reporter was demonstrating a beech duke to a prospective purchaser when the left engine lost power. The purchaser in the left seat inquired of the reporter, 'is this part of my initial training?' and the reporter assured him that it was not. An emergency was later declared and a safe landing was made by the reporter. As the aircraft slowed, the pilot attempted to turn off at taxiway C into the good engine, but the aircraft would not turn that direction so he stopped at the intersection of the 2 main runways, effectively closing the airport to air carrier traffic. Allegedly the airport manager was very upset with the reporter and had a tug remove the aircraft quickly. The maintenance technicians found that a spring that holds the turbocharger to the exhaust manifold had broken rendering the turbocharger ineffective.

Title: AN INSTRUCTOR PLT ACTING AS A SALES REPRESENTATIVE HAS THE L ENG'S TURBOCHARGER TENSIONING SPRING BREAK ALLOWING THE TURBOCHARGER TO DISCONNECT FROM THE MANIFOLD AND THE ENG TO LOSE PWR. A SAFE EMER LNDG WAS MADE AND THE ACFT WAS TOWED TO PARKING.

Narrative: ON THIS SALE DEMO WAS CLBING THROUGH 15000 FT MSL ON OUR WAY TO FL230. L ENG QUIT MAKING PWR. I PROCEEDED TO ASK ZMP TO RETURN TO OMA. I ALSO ASKED FOR LOWER, SO THEY ALLOWED ME TO DSND TO 11000 FT. DURING THE TROUBLESHOOTING WE TRIED TO LEVEL OFF AT 11000 FT AND WAS UNABLE TO HOLD ALT. I REQUESTED LOWER AND WAS TURNED OVER TO OMA APCH. AS I CHKED IN, I DECIDED IT WAS TIME TO DECLARE AN EMER AND DO A PRECAUTIONARY SHUTDOWN OF THE L ENG BECAUSE OF THE SMELL OF BURNING OIL IN THE COCKPIT. WE SHUT THE ENG DOWN. I CALLED THE ARPT IN SIGHT AND APCH CLRED US FOR THE VISUAL TO RWY 32L AFTER THEY ASKED US WHAT RWY WE WANTED. WHEN WE WERE TOLD TO SWITCH FREQ AND GO TO TWR WE ACKNOWLEDGED. UPON SWITCHING TO TWR THE CTLR CLRED US FOR THE VISUAL TO RWY 36. I REPLIED THAT WE WANTED RWY 32L. UPON LNDG I THOUGHT WE WOULD BE ABLE TO TAXI, BUT THE ACFT WOULD NOT BECAUSE OF EXCESSIVE PWR ON THE R SIDE. WE ENDED UP STOPPED IN THE INTXN OF RWY 32L AND RWY 36, HOLDING ALL TFC UNTIL THEY COULD GET A TUG OUT TO TOW US OFF THE RWY. I PROBABLY COULD HAVE STOPPED AND HELD SHORT OF RWY 36. I WAS MORE WORRIED ABOUT GETTING US DOWN THAN I WAS ABOUT INCONVENIENCING AN AIRLINE FLT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR WAS DEMONSTRATING A BEECH DUKE TO A PROSPECTIVE PURCHASER WHEN THE L ENG LOST PWR. THE PURCHASER IN THE L SEAT INQUIRED OF THE RPTR, 'IS THIS PART OF MY INITIAL TRAINING?' AND THE RPTR ASSURED HIM THAT IT WAS NOT. AN EMER WAS LATER DECLARED AND A SAFE LNDG WAS MADE BY THE RPTR. AS THE ACFT SLOWED, THE PLT ATTEMPTED TO TURN OFF AT TXWY C INTO THE GOOD ENG, BUT THE ACFT WOULD NOT TURN THAT DIRECTION SO HE STOPPED AT THE INTXN OF THE 2 MAIN RWYS, EFFECTIVELY CLOSING THE ARPT TO ACR TFC. ALLEGEDLY THE ARPT MGR WAS VERY UPSET WITH THE RPTR AND HAD A TUG REMOVE THE ACFT QUICKLY. THE MAINT TECHNICIANS FOUND THAT A SPRING THAT HOLDS THE TURBOCHARGER TO THE EXHAUST MANIFOLD HAD BROKEN RENDERING THE TURBOCHARGER INEFFECTIVE.
