Narrative:
Fgt X proceeded inbound for the overhead approach runway 5R I instructed it to break right non-standard at the northeast field boundaries to pass behind an fgt Y 3 mi TACAN approach runway 32L. The fgt X broke left and entered a left downwind in front of the fgt Y. I issued traffic to both. They both reported each other is sight. Both aircraft continued on their respective flight paths and did not alter until the fgt Y came within about 300 ft of the fgt X and then the fgt Y dipped below the fgt X and missed by about 50 ft. In the purest sense, by issuing traffic and each other having each other in sight. I believe my legal requirements in accordance with FAA order 7110.65F would have been met, however though neither aircraft complained then or later for me it was too close. If the fgt X at the same time as the fgt Y decided to avert by going under, there would have been a race for the deck and eventually a building hit or a mid-air. If I had a chance to do it again I would have done one or more of the following. Reiterate to the fgt X the non- standard right break and traffic to pass behind. Waved off the TACAN fgt Y as soon as the fgt X broke wrong. Ask the fgt X to report the fgt Y in sight prior to the aircraft reaching the break point.

Title: FGT X NON ADHERENCE TO ATC INSTRUCTION HAD NMAC WITH FGT Y. SEE AND AVOID CONCEPT. EVASIVE ACTION TAKEN.
Narrative: FGT X PROCEEDED INBOUND FOR THE OVERHEAD APCH RWY 5R I INSTRUCTED IT TO BREAK R NON-STANDARD AT THE NE FIELD BOUNDARIES TO PASS BEHIND AN FGT Y 3 MI TACAN APCH RWY 32L. THE FGT X BROKE L AND ENTERED A L DOWNWIND IN FRONT OF THE FGT Y. I ISSUED TFC TO BOTH. THEY BOTH RPTED EACH OTHER IS SIGHT. BOTH ACFT CONTINUED ON THEIR RESPECTIVE FLT PATHS AND DID NOT ALTER UNTIL THE FGT Y CAME WITHIN ABOUT 300 FT OF THE FGT X AND THEN THE FGT Y DIPPED BELOW THE FGT X AND MISSED BY ABOUT 50 FT. IN THE PUREST SENSE, BY ISSUING TFC AND EACH OTHER HAVING EACH OTHER IN SIGHT. I BELIEVE MY LEGAL REQUIREMENTS IN ACCORDANCE WITH FAA ORDER 7110.65F WOULD HAVE BEEN MET, HOWEVER THOUGH NEITHER ACFT COMPLAINED THEN OR LATER FOR ME IT WAS TOO CLOSE. IF THE FGT X AT THE SAME TIME AS THE FGT Y DECIDED TO AVERT BY GOING UNDER, THERE WOULD HAVE BEEN A RACE FOR THE DECK AND EVENTUALLY A BUILDING HIT OR A MID-AIR. IF I HAD A CHANCE TO DO IT AGAIN I WOULD HAVE DONE ONE OR MORE OF THE FOLLOWING. REITERATE TO THE FGT X THE NON- STANDARD R BREAK AND TFC TO PASS BEHIND. WAVED OFF THE TACAN FGT Y AS SOON AS THE FGT X BROKE WRONG. ASK THE FGT X TO RPT THE FGT Y IN SIGHT PRIOR TO THE ACFT REACHING THE BREAK POINT.
