Narrative:

My student and I were going VFR from ubg under flight following and asked for a VFR ILS approach to mmv. Approach control advised us that we should proceed direct to the LOM, but no traffic separation would be provided. We were cleared for the approach but maintain VFR at LOM, so we started procedure turn outbound and advised approach. At approximately same time, an small aircraft called approach for vector. He was advised he was #2 for approach. We were then instructed to contact local CTAF and report back to approach on the missed approach climb. We then switched to CTAF and turned inbound. We advised mmv we were inbound. At LOM we advised again LOM inbound. About 1 min passed and I heard the small aircraft advise LOM inbound. I replied to their call that we were 2 mi out indicating 90 KTS. The small aircraft advised us that he had us in sight! We were still inbound at approximately 500 ft MSL when I saw the small aircraft passing us on the left. As he passed, I took the control from the student and proceeded to make a climbing right turn to resolve any other problem from the small aircraft. I feel the small aircraft failed to observe any separation from us, we were #1 on the approach. If he would have said his intention or advised us of a problem we would have broken off approach. I had advised him of our speed so he should have said he planned on overtaking us. As we climbed out I saw the small aircraft execute a missed approach at approximately 400 MSL, so I know they had no engine problems. Possible correction to problem is higher procedure turn altitude so approach could see aircraft as it is on procedure, so other aircraft would not be turned in with vector to follow other aircraft. I don't know of anything I could have done other than been IFR, but that still wouldn't stop another VFR aircraft from flying approach.

Title: NMAC BTWN 2 SMA TRAINING ACFT AT NON TWR ARPT.

Narrative: MY STUDENT AND I WERE GOING VFR FROM UBG UNDER FLT FOLLOWING AND ASKED FOR A VFR ILS APCH TO MMV. APCH CTL ADVISED US THAT WE SHOULD PROCEED DIRECT TO THE LOM, BUT NO TFC SEPARATION WOULD BE PROVIDED. WE WERE CLRED FOR THE APCH BUT MAINTAIN VFR AT LOM, SO WE STARTED PROC TURN OUTBOUND AND ADVISED APCH. AT APPROX SAME TIME, AN SMA CALLED APCH FOR VECTOR. HE WAS ADVISED HE WAS #2 FOR APCH. WE WERE THEN INSTRUCTED TO CONTACT LCL CTAF AND RPT BACK TO APCH ON THE MISSED APCH CLB. WE THEN SWITCHED TO CTAF AND TURNED INBOUND. WE ADVISED MMV WE WERE INBOUND. AT LOM WE ADVISED AGAIN LOM INBOUND. ABOUT 1 MIN PASSED AND I HEARD THE SMA ADVISE LOM INBOUND. I REPLIED TO THEIR CALL THAT WE WERE 2 MI OUT INDICATING 90 KTS. THE SMA ADVISED US THAT HE HAD US IN SIGHT! WE WERE STILL INBOUND AT APPROX 500 FT MSL WHEN I SAW THE SMA PASSING US ON THE L. AS HE PASSED, I TOOK THE CTL FROM THE STUDENT AND PROCEEDED TO MAKE A CLBING R TURN TO RESOLVE ANY OTHER PROB FROM THE SMA. I FEEL THE SMA FAILED TO OBSERVE ANY SEPARATION FROM US, WE WERE #1 ON THE APCH. IF HE WOULD HAVE SAID HIS INTENTION OR ADVISED US OF A PROB WE WOULD HAVE BROKEN OFF APCH. I HAD ADVISED HIM OF OUR SPD SO HE SHOULD HAVE SAID HE PLANNED ON OVERTAKING US. AS WE CLBED OUT I SAW THE SMA EXECUTE A MISSED APCH AT APPROX 400 MSL, SO I KNOW THEY HAD NO ENG PROBS. POSSIBLE CORRECTION TO PROB IS HIGHER PROC TURN ALT SO APCH COULD SEE ACFT AS IT IS ON PROC, SO OTHER ACFT WOULD NOT BE TURNED IN WITH VECTOR TO FOLLOW OTHER ACFT. I DON'T KNOW OF ANYTHING I COULD HAVE DONE OTHER THAN BEEN IFR, BUT THAT STILL WOULDN'T STOP ANOTHER VFR ACFT FROM FLYING APCH.
