AN ACR MLG HAD AN NMAC WITH AN SMA WHILE LOOKING AT ANOTHER SMA.

Narrative

I WAS DOING TFC WATCH AT OR BELOW 2200 MSL. HEADED NBOUND. DEP CTLR TOLD ME OF ACR TFC S OF MY POS WHICH I CALLED IN SIGHT. THE CTLR ALSO POINTED ME OUT TO THE ACR AND HE CALLED ME IN SIGHT; AFTER WHICH THE CTLR GAVE HIM VISUAL APCH CLRNC AND TOLD HIM TO MAINTAIN VISUAL SEPARATION WITH MY ACFT; WHICH HE ACCEPTED. AT THIS POINT; I LOST SIGHT OF THE ACR JET AS HE WENT THROUGH MY 5-6 O'CLOCK POS. APCH CTLR THEN POINTED OUT ADDITIONAL SMA TFC TO THE ACR AT ABOUT HIS 1 O'CLOCK POS. ACR CALLED THE TFC IN SIGHT AND SAID HE WOULD MAINTAIN VISUAL SEPARATION. AT THIS POINT; WE HAD FINISHED OUR RPTS ON THE RADIO; SO I RADIOED TO APCH THAT WE WERE READY TO TURN INBOUND FOR LNDG. HE ACKNOWLEDGED; SAYING I WAS #3 FOR THE ARPT FOLLOWING AN ACR AND ANOTHER SMA AT ABOUT MY 2-3 O'CLOCK POS. I TOLD HIM I WOULD MAKE A R TURN TO GET THE SMA IN SIGHT. IMMEDIATELY AFTER BANKING TO THE R; THE ACR JET CAME FROM R TO L RIGHT IN FRONT OF ME ON A L BASE FOR THE ARPT (RWY 22). I GUESS AT THE LAST MIN HE (OR HIS TCASII) SAW ME AND HE SAID; 'ACR JUST HAD A NEAR MISS; 300 FT.' THE CTLR TOLD HIM THAT WAS THE TFC HE WAS SUPPOSED TO BE MAINTAINING VISUAL WITH. ACR SAID NO; THAT HE HAD THE TFC (SMA) OFF TO HIS R (I WAS TO HIS L). THE APCH CTLR TOLD HIM THAT WAS THE OTHER PREVIOUSLY CALLED TFC. ACR SAID HE WOULD FILE A RPT ON THE GND. I PROCEEDED INBOUND AND LANDED BEHIND THE ACR AND THE SMA WITHOUT EVENT. I THINK THE ACR PLT THOUGHT THERE WAS ONLY 1 OTHER ACFT HE WAS SUPPOSED TO BE LOOKING FOR; OR FORGOT ABOUT MY ACFT ENTIRELY. IN FUTURE; I WILL MAKE CERTAIN TO CONSTANTLY KEEP ALL TFC IN VISUAL CONTACT. I RELIED ON THE ACR PLT TO MAINTAIN SEPARATION AND ALSO ON THE CTLR TO SAY SOMETHING IF WE WERE GETTING TOO CLOSE.
