2 SMA'S HAD AN NMAC IN THE TFC PATTERN.

Narrative

WHILE ON FINAL APCH TO RWY 24 BOWMAN FIELD AFTER RPTING 2 MI FINAL; WE WERE ASKED IF WE SAW A TWIN SMA Y AT OUR 10 O'CLOCK. MY STUDENT SAID 'NO' AND THEN A COUPLE OF SECONDS LATER RPTED HIM IN SIGHT. TWR THEN TOLD US TO 'FOLLOW THAT TFC; NUMBER 2.' MY STUDENT SAID 'ROGER' AND TURNED TO OUR L TO FALL IN BEHIND THE TWIN. I HAD THE TFC IN SIGHT THE WHOLE TIME AND AT THIS TIME TOOK THE ACFT TO MANEUVER AROUND THE TWIN SMA Y. WE WERE ALREADY ON FINAL BEFORE TURNING; SO OUR ALT WAS BELOW HIS ABOUT 400 FT. I ALSO AVOIDED HIS FLT PATH BY AT LEAST 100 FT. WE THEN WERE DIRECTED BY TWR TO ENTER THE UPWIND WHICH WE DID. I GAVE THE ACFT BACK TO MY STUDENT AT THIS TIME. AT ABOUT THIS TIME THE PLT OF THE TWIN SMA Y TOLD TWR THERE WAS A RETRACTABLE SMA X THAT WAS HEAD-ON TO HIM AND THEN PARALLELING HIS FLT PATH 'NOT TALKING TO ANYBODY.' WE TOLD THE TWR WE WERE PARALLELING THE TWIN AND WERE ENTERING THE UPWIND. TWR'S TELLING US TO FOLLOW SMA Y WHEN WE WERE ON FINAL; LOWER THAN THE OTHER ACFT; I BELIEVE CAUSED THE PROBLEM. IF THE TWR HAD DIRECTED A R 360 OR TO ENTER THE UPWIND AT THAT TIME; IT WOULD HAVE WORKED SMOOTHER. ALSO; IF THEY HAD ALLOWED US TO CONTINUE; THERE PROBABLY WOULD NOT HAVE BEEN A CONFLICT.
