Narrative:

The following is a report on the engine shutdown in-flight which occurred on jul/xa/01 on a company B200 aircraft. This was a part 91 operation with 2 employees of company X, a co-owner of the aircraft, along with mr X acting as observer pilot on board. Aircraft departed from macon, GA, at XA35 and arrived in the wisconsin rapids area about XB00. While in VFR conditions on downwind leg for landing on runway 20, the right engine fire warning light illuminated. I immediately idled back the right engine, then thinking the sun might be striking the sensor, I briefly changed heading. When this did not extinguish the light, I shut the engine down by memory items, followed by mr X reading the items in the emergency shutdown checklist. I then asked mr X to look for any indication first officer fire, ie, smoke, flames, etc. Mr X noticed trace of smoke. I verified. I then proceeded to fire the right engine fire bottle. The smoke stopped and the fire light was extinguished. After landing and opening the engine cowl, it was evident that the cause of the problem was a malfunction and lockup of the air conditioner compressor and the burning up of the compressor drive clutch.
