SAF CTLR DESCRIBED NMAC WHEN IFR TFC FAILED TO ENTER PATTERN AS EXPECTED AND CONFLICTED WITH VFR TFC ON PRACTICE VOR APCH.

Narrative

CIRRUS WAS ON PRACTICE VOR 33 APCH VICINITY PROC TURN. AS ZAB HAD IFR INBOUND; I PASSED TFC ON CIRRUS AND REQUESTED BEACON CODE. GIVEN XXXX. ACFT ACKNOWLEDGED; ZAB PASSED CITATION AND REQUESTED TO PASS OVER ARPT FROM FTI VISUAL APCH TO ENTER L DOWNWIND TO RWY 2 FOR DSCNT PURPOSES; WHICH I APPROVED. I HAD ADVISED CIRRUS TO EXPECT CITATION TFC FROM FTI EARLIER. THEN ADVISED CIRRUS THAT CITATION WOULD OVERFLY ARPT TO W SIDE L DOWNWIND. WHEN CITATION CAME UP ON FREQ HE ADVISED HE WAS ON R DOWNWIND TO RWY 2. I ADVISED AND QUESTIONED THAT AS HE WAS EXPECTED TO OVERFLY ARPT AND THUS NOT BE TFC FOR CIRRUS. I ASKED ALT. BOTH WERE AT 7800/7900 FT. I SUGGESTED CITATION CLB FOR TFC IMMEDIATE VICINITY. CITATION CLBED; CIRRUS DUCKED UNDER TAKING EVASIVE ACTION. I SAW CITATION CLB RAPIDLY OVER CIRRUS. CITATION LATER SAID HE HAD CHANGED MIND ON OVERFLT FOR R DOWNWIND DUE TO TCAS TFC 500 FT BELOW. I WAS NOT AWARE OF ANY OTHER TFC AT THAT ALT EXCEPT CIRRUS WHICH WOULD HAVE BEEN ON CITATION'S L SIDE UNTIL HE TURNED INTO HIM. ZAB DID NOT LET US KNOW ABOUT CHANGE NOR DO I BELIEVE THEY PASSED TFC TO THE CITATION ON THE CIRRUS WHICH THEY SHOULD HAVE HAD TARGET ON XXXX CODE. PLT OF CIRRUS ADVISED ME HE INTENDED TO FILE RPT AS WELL. WE ARE LONG OVERDUE FOR RADAR; SLAVED OR STANDALONE. THIS IS THE SECOND CLOSE CALL OF THIS TYPE IN THE PAST 3 WKS. SUPPLEMENTAL INFO FROM ACN 755702: FLT WAS AN INST CHK RIDE. THE APPLICANT COMPLETED THE PROC TURN AND WAS INBOUND ON THE VOR 33 APCH. WHILE 3-4 MI OUT; SAF TWR REQUESTED WE SQUAWK XXXX FOR CTR BECAUSE THERE WAS A CITATION INBOUND. WE COMPLIED. WE THEN HEARD THE CITATION ON THE FREQ AND WE ANNOUNCED 3 MI SE OF THE VOR ON THE APCH. SAF IS A NON RADAR ARPT AND THE TWR CTLR ACKNOWLEDGED AND THANKED US FOR THE RPT. AS WE APCHED THE VOR WE HEARD TWR QUERY THE CITATION ON THEIR ALT. THEY WERE AT 7900 FT. WE WERE AT 7800 FT AND JUST PASSING THE VOR. THERE WAS SOME DISCUSSION AS TO THE CITATION'S INTENTION AS TO HOW THEY WERE GOING TO ENTER TFC FOR RWY 2 AT SAF. TWR THOUGHT THE CITATION HAD BEEN INSTRUCTED TO CROSS OVER THE FIELD AND ENTER L TFC. THE CITATION THOUGHT THEY WERE SUPPOSED TO ENTER R TFC FOR RWY 2. I LOOKED TO MY R AND SAW THE CITATION AT 3 O'CLOCK POS AT OUR ALT AND HEADED IN OUR DIRECTION. I ANNOUNCED 'MY CTLS' AND TOOK THE ACFT FROM THE APPLICANT. I TURNED AWAY FROM THE CITATION AND DSNDED IMMEDIATELY. THE CITATION PASSED BEHIND US AND ENTERED R TFC FOR RWY 2. I RETURNED THE ACFT TO THE APPLICANT WHO CONTINUED THE APCH (AND THE CHK RIDE) SUCCESSFULLY. SAF TWR WORKS DILIGENTLY TO VISUALLY SEPARATE TFC AT THIS ARPT. THIS COULD HAVE BEEN AVOIDED IF THERE HAD BEEN CLEARER HDOF FROM CTR TO TWR. IT IS MY UNDERSTANDING THAT A CTR TRAINING SIT MAY HAVE CONTRIBUTED TO THE LOSS OF SEPARATION.
