Narrative:

I am a first officer flying for a commuter airline. During approach phase into msp airport, one of the passenger noticed smoke in the cabin and reported it to us, the crew members. The captain continued to fly the airplane and asked for priority handling as well as emergency vehicles. The captain asked me to take my fire extinguisher and investigate the smoke. As I entered the cabin I saw a small flame up near the overhead light in the very front of the cabin on the right hand side. I immediately extinguished the 3' flame. Meanwhile, the captain pulled out the associated circuit breakers and the cabin lights were shut off. We landed without incident and the rescue crew was sent back after we were sure it was under control. The passenger were unloaded as soon as possible, and no one was hurt. There were 7 passenger on board and they all remained very calm. Our maintenance looked at the damaged area and believed it to be caused by a flourescent light bulb that had shorted out. (The bulb was in working condition before the flight.) there was very little damage done (a melted wire and a small black spot left by the smoke) and the aircraft was back in service shortly. All the appropriate paperwork was filled out and the chief pilot said that the captain and I did an excellent job in handling the situation.
