PHL CTLR EXPERIENCED OPERROR AT 5000 WHEN FAILING TO ISSUE A TURN IN TIME TO MAINTAIN SEPARATION; ASSUMING INCORRECT ROUTING.

Narrative

WORKING AN ARR SECTOR AT A NOT PARTICULARLY BUSY TIME; I ACCEPTED A VERBAL HDOF ON A 7000 FT TARGET W OF THE BOUNDARY WITH PCT. I WAS ADVISED OF ACFT CALL SIGN; TYPE; AND DEST (CDW) AND WAS TOLD THAT TFC WAS NOT ON THE NORMAL RTE FOR DEST. I ADVISED PCT THAT IF THE TFC WAS CONCERNED ABOUT WX THAT PIREPS CONSISTED OF LIGHT RAIN/EXCELLENT VISIBILITY ON THE NORMAL RTE TO CDW. WHEN THE TFC CHKED IN ON FREQ I ASSUMED THEY WOULD BE NAVING ON THE NORMAL RTE BECAUSE OF THE PIREPS I HAD PASSED TO PCT. I QUESTIONED THE PLT ABOUT THE RTE AND INSTRUCTED HIM TO TURN TOWARDS THE FIX MXE. AT THIS POINT; 2 THINGS ARE IMPORTANT: 1) I HAD NOT INITIATED A TRACK ON THE TARGET; AND 2) THE ACFT WAS HEADING TOWARDS ADJACENT AIRSPACE WITHOUT COORD. AT THE SAME TIME; OTHER PERSONNEL WERE ATTEMPTING TO AMEND THE FLT PLAN VIA THE NAS SYS SO THAT AUTOMATIC TRACK ACQUISITION WOULD OCCUR AND FLT PROCESSING WOULD CONTINUE TO DEST. WHEN IT WAS OBVIOUS TO ME THAT THE SR22 WAS NOT HEADING THE DIRECTION I NEEDED IN A TIMELY MANNER; I ISSUED A HDG OF 360 DEGS TO DIRECT THE TFC TOWARD MY AIRSPACE AND AWAY FROM OTHER POTENTIAL TFC. CONCURRENTLY; I HAD ACCEPTED AN INTRAFAC HDOF ON A BE20; NOT YET ON MY FREQ. THE BE20 WAS BEING VECTORED AWAY FROM POTENTIAL TFC; BY ANOTHER CTLR; AND TOWARDS MY AIRSPACE TO EVENTUALLY BE ASSIGNED A 360 DEG HDG PER THE FLT PROGRESS STRIP THAT HAD BEEN PASSED TO ME. SUBSEQUENTLY; STANDARD SEPARATION WAS LOST WHEN THE BE20 WAS NOT TURNED TO A 360 DEG HDG IN TIME TO LATERALLY SEPARATE FROM THE NBOUND SR22 AT THE SAME ALT (5000 FT).
