Narrative:

Second aircraft was on runway 5R ILS to yip. We were returning to the runway 5 NDB after a missed approach (visibility practice). When on a heading of 230 degrees, yip tower advised to continue southbound to allow traffic approaching runway 5 to pass. We continued on heading 230 degrees for a while, then asked yip tower for position of the other aircraft. They responded he was on final for runway 5. I interpreted this to mean the other aircraft had already passed since we were about 4 mi out and turned toward the NDB 5R LOM outbnd. A short time later tower asked if we had the other aircraft in sight. We replied, 'no,' and were now alerted and quickly saw the approaching aircraft above and to our right on an opp heading. It is normal to practice NDB 5R approachs west/O the benefit of detroit radar in visibility conditions, so it is up to the pilot trnee to fly to the NDB outbnd, perform the procedure turn and then report to the tower our position. Since we did not hear the xmissions of the other small aircraft, I believe they were working the approach with detroit radar inbound on the 5R ILS while we were maneuvering outbnd on the NDB 5R approach west/O detroit radar. Immediately after the miss, tower decided to have us work with detroit radar for all subsequent approachs. Corrective action would be for all yip approachs to be coordinated with detroit radar.

Title: PLT OF SMA TRAINING FLT HAD NMAC WITH ANOTHER SMA INBOUND TO YIP.

Narrative: SECOND ACFT WAS ON RWY 5R ILS TO YIP. WE WERE RETURNING TO THE RWY 5 NDB AFTER A MISSED APCH (VIS PRACTICE). WHEN ON A HDG OF 230 DEGS, YIP TWR ADVISED TO CONTINUE SBND TO ALLOW TFC APCHING RWY 5 TO PASS. WE CONTINUED ON HDG 230 DEGS FOR A WHILE, THEN ASKED YIP TWR FOR POS OF THE OTHER ACFT. THEY RESPONDED HE WAS ON FINAL FOR RWY 5. I INTERPRETED THIS TO MEAN THE OTHER ACFT HAD ALREADY PASSED SINCE WE WERE ABOUT 4 MI OUT AND TURNED TOWARD THE NDB 5R LOM OUTBND. A SHORT TIME LATER TWR ASKED IF WE HAD THE OTHER ACFT IN SIGHT. WE REPLIED, 'NO,' AND WERE NOW ALERTED AND QUICKLY SAW THE APCHING ACFT ABOVE AND TO OUR RIGHT ON AN OPP HDG. IT IS NORMAL TO PRACTICE NDB 5R APCHS W/O THE BENEFIT OF DETROIT RADAR IN VIS CONDITIONS, SO IT IS UP TO THE PLT TRNEE TO FLY TO THE NDB OUTBND, PERFORM THE PROC TURN AND THEN RPT TO THE TWR OUR POS. SINCE WE DID NOT HEAR THE XMISSIONS OF THE OTHER SMA, I BELIEVE THEY WERE WORKING THE APCH WITH DETROIT RADAR INBND ON THE 5R ILS WHILE WE WERE MANEUVERING OUTBND ON THE NDB 5R APCH W/O DETROIT RADAR. IMMEDIATELY AFTER THE MISS, TWR DECIDED TO HAVE US WORK WITH DETROIT RADAR FOR ALL SUBSEQUENT APCHS. CORRECTIVE ACTION WOULD BE FOR ALL YIP APCHS TO BE COORDINATED WITH DETROIT RADAR.
