Narrative:

Enroute and in our initial descent from 16;000 down to 7;000 ft (assigned by the controller); we experienced a partial power loss in the right engine. Figuring it was a turbo-charger failure; I immediately asked for vectors to the nearest suitable airport. Given the weather conditions; it was not too difficult to spot the airport and keep it insight. As I was setting up for the visual approach; I selected the gear to the down position and it would not fully extend. I decided to fly the airplane while the owner of the aircraft; sitting in the co-pilot's seat; manually extended the gear. While he tended to that situation; I declared the emergency with center and asked for emergency equipment to be standing by. We stayed on frequency with the center controller until after we landed. We landed; canceled our IFR on center frequency and taxied to the parking area without further incident. After shutdown; I called flight service to ask them if anything (paperwork; etc.) needed to be completed. He put me on hold while he contacted the center manager and then said that nothing was required of me. He said the ATC was glad we were on the ground safe and that they did not need any statement or paperwork from me. Just as an aside; I attend recurrent training on this aircraft once a year and it sure does help with all sorts of scenarios and your reactions to them! What a great thing!!
