ABI GND CTLR DESCRIBED CONFLICT EVENT WITH TWO ARR ACFT DURING AN OVERTAKE SITUATION; CITING FACILITY TRAINING PROCS AS CONTRIBUTORY.

Narrative

ACFT Y; IFR; LOC BACK COURSE APCH TO RWY 17L. ACFT X; IFR; VISUAL APCH TO RWY 17R. THE PLT OF ACFT Y CALLED THE CTLR WORKING LCL CTL INBOUND ON THE BACK COURSE APCH. THE CTLR CLRED THE PLT OF ACFT Y 'FOR THE OPTION OF RWY 17L' THEN CORRECTED THE CLRNC TO 'CLRED LOW APCH AT OR ABOVE 2300 FT' BECAUSE THE RWY 17L WAS CLOSED. THE PLT OF ACFT Y THEN ASKED TO SIDESTEP TO RWY 17R. THE CTLR CLRED THE ACFT 'Y BEHIND A BARRON SHORT FINAL CLRED TO LAND RWY 17R.' SHORTLY AFTER ACFT Y; I CALLED INBOUND ON FINAL RWY 17R VISUAL APCH. THE CTLR 'CLRED ACFT #2 CLRED TO LAND RWY 17R' (ABOUT 70-80 KTS OF CLOSURE/OVERTAKE). THE PLT OF ACFT Y ADVISED 'BRAKING OFF THE LOC FOR RWY 17R.' ACFT X WAS 1 - 1 1/2 MI BEHIND AND TO THE R. MYSELF AND ANOTHER CTLR STARTED YELLING AT THE CTLR TO 'CLB ACFT X.' THE CTLR TURNED ACFT Y TO THE E AND TURNED ACFT X TO THE R. CORRECTIVE ACTIONS: THE FAA HAS FOR ABOUT 1 - 1 1/2 YRS STARTED CERTIFYING THESE STUDENTS ON POS WITH NO RECOMMENDATIONS FROM THE TRAINING TEAMS. THE FAA NEEDS TO FOLLOW THEIR OWN ORDERS! SUPPLEMENTAL INFO FROM ACN 782951: APCH VECTORED ME TO HDG 270 DEGS (FROM 230 DEGS). SAID HE HAD MULTIPLE TFC. TWR THEN VECTORED ME TO HDG 250 DEGS; THEN 230 DEGS TO JOIN FINAL. SAID CLR TO LAND; #2; FOLLOWING ACFT Y. I HAD JOINED FINAL AT THIS TIME. I WAS AT NORMAL APCH SPD. HE LATER ASKED ME IF I HAD ACFT Y IN SIGHT. I SAID I DID NOT. I RECEIVED A TFC ALERT; BUT NOT RA. HE SAID TO CLB (OUT OF 2500 FT) TO 3000 FT AND EXECUTE A R 360 DEG TURN. HE THEN TOLD ACFT Y TO EXECUTE A L 360 DEG TURN. AT THE END OF MY 360 DEG TURN; HE CLRED ME TO LAND AHEAD OF ACFT Y THIS TIME. NORMALLY; I BELIEVE; IF YOU ARE EXPECTED TO FIND THE OTHER TFC; YOU ARE TOLD TO FOLLOW THE OTHER ACFT AND BEGIN TURN TO FINAL WHEN YOU HAVE A VISUAL AND CAN MAINTAIN SEPARATION AND YOU'RE OFTEN ASKED TO CONFIRM HE'S IN SIGHT. I BELIEVED THAT THE TWR WAS MAINTAINING SEPARATION BY THE VECTORS I WAS GIVEN. IT WAS VERY BRIGHT WITH THE SUN AHEAD AND TO THE R AND HAD HE ASKED ME TO MAINTAIN A VISUAL WITH THE TFC; I AM NOT SURE I COULD HAVE. I COULD HAVE TOLD HIM I DIDN'T HAVE THE OTHER TFC IN SIGHT WHEN HE CLRED ME TO LAND; BUT I DON'T BELIEVE THAT'S CUSTOMARY UNLESS YOU ARE TOLD TO FOLLOW THE TFC AND I BELIEVE IN A BUSY ENVIRONMENT THAT WOULD BE SAID TOO OFTEN AND IT IS NOT NECESSARY FOR THE PLT TO HAVE THE TFC IT'S FOLLOWING IN SIGHT IN A RADAR CTLED ENVIRONMENT UNLESS THE TWR OR CTLR INSTRUCTS. I BELIEVE THE APCH CTL AND TWR COULD HAVE KEPT ME ON THE WIDE VECTOR LONGER AND/OR TOLD ME TO MAINTAIN A LOWER SPD AND ANTICIPATED THE SPACING BETTER. I BELIEVE I COULD TELL THE PLT OF ACFT Y WAS IN TRAINING AND PERHAPS HE DID SOMETHING ODD TO SLOW HIS PATH TO THE RWY COMPARED TO NORMAL.
