PBI LCL CTLR CHANGES DEP HDG OF A CL44 WITHOUT COORD RESULTING IN A CONFLICT WITH A PRECEDING MD80 IN PBI DEP CTLR'S AIRSPACE.

Narrative

MD80 WAS ON 030 DEG VECTOR TO JOIN A699 ON COURSE CLBING OUT OF 5000 FT. THE CL64 WAS ON 075 DEG TWR ASSIGNED HDG; CLBING TO 4000 FT. THE PBI 4 SID AND SOP REQUIRED TURBOJET ACFT ON 095 DEG HDG CLBING TO 4000 FT. THE MD80 WAS TURNED OVER WENDE INTXN TO HDG 030 DEGS AS STIPULATED BY SOP AND CLBED TO 10000 FT. I WENT TO SUA TWR TO RELEASE A DEP AND THEN CAME BACK TO IDENT THE CL64 AND ISSUE CTL INSTRUCTIONS WHEN I OBSERVED HIM ON A TRACK THAT INTERCEPTED THE MD80'S FLT PATH. I ASKED THE OPS SUPVR IF HE SAW THE CL64'S TRACK AND HE CHKED WITH THE TWR. THE TWR HAD TURNED THE CL64 TO GET DIVERGING HDGS WITH THE PREVIOUS MD80 DEPARTING. NO COORD WAS COMPLETED FOR THE 075 DEG HDG; SO I ASSUMED THE CL64 WAS ON 095 DEGS (PB14/SOP) WHILE I COMPLETED THE COORD WITH SUA TWR. WHEN I OBSERVED THE MD80 AND CL64; I SAW THEY WERE SEPARATED BY 1000 FT. ONLY AFTER MGMNT PULLED THE DATA DID THEY ESTABLISH A LOSS OF SEPARATION WHEN THE MD80 WAS TURNED. I FOLLOWED SOP AND DID NOT OBSERVE THE CL64 ON 075 DEG HDG; NOR WAS I INFORMED HE WOULD BE DEVIATING FROM THE SID. THE CL64 HAD THE MD80 IN SIGHT AND I DIDN'T CLB THE CL64 UNTIL I ESTABLISHED APPROPRIATE SEPARATION; UNKNOWN I HAD ALREADY LOST IT. AS OF THIS WRITING; I'M STILL WAITING FOR MGMNT'S DECISION (10 DAYS) AND IT APPEARS THE PROVISIONS OF THE SID/SOP ARE BEING OVERLOOKED IN PREFERENCE TO MY TURNING THE MD80. I NEVER OBSERVED OR IDENTED THE CL64 UNTIL I INITIATED THE TURN AWAY FROM THE MD80.
