Human Factors
I was working with a student in his personal airplane. We were performing the GPS/RNAV 17 approach at MIO. We were inside the final approach fix; IJEDY descending from 2;500 feet MSL. My student; a private rated pilot; made the announcement we were 5 miles north at the final approach fix for the RNAV/GPS 17. A crop duster was departing 35 (Winds were calm) and announced he had us in sight and he would be making a left turn to the west. I observed this airplane departing; and told my student that if necessary I would take control of the airplane but didn't think this would be necessary. About that time I observed a second airplane; a Mooney directly below us and slightly to the right; estimated at 150-200 feet [from us]. He had made no calls up to this point. I made a call on the radio saying I had the crop duster [in] sight and a Mooney on final; to let the crop duster know he had opposite direction traffic besides us. It was then the Mooney made an announcement. He continued the approach and landed in front of us; causing us to go around. He apologized and said the he was on VFR flight following; that ATC did tell him he had traffic; but he thought we were just maneuvering. We had been on this approach since we intercepted MEBIE; IAF. I feel his reliance to ATC VFR flight following; his lack of seeing and Avoiding and his improper pattern entry at a non-towered airport were contributing factors.
