Narrative:

I was conducting a VFR cross country and on the way back; about 8 miles from destination; I saw a small blue flame coming from underneath the right engine; it looked like by the cowl flap. It continued to get worse while in descent so I decided to declare an emergency for a right engine fire. I followed the emergency flow and checklist for an engine fire. Cut off the fuel; and feathered the prop. I squawked 7700 and landed. Safe landing and no damage. The main reason why I felt the need to shut down the engine and declare an emergency is because the flame was big enough and kept getting worse. We were descending at 16' manifold pressure and all gauges were normal. My student was on board.
