ZBW CTLR FAILS TO COMPLY WITH COORD AUTOMATED INFO HDOF/ TRANSFER PROC; RESULTING IN AN OPERROR BTWN AN A321 AND A CARJ.

Narrative

I WAS THE RADAR CTLR AT THE BOSOX SECTOR. DURING MY TIME AT THIS POS; I WAS INVOLVED IN A SIT CONCERNING ACR X AND ACR Y. ACR X WAS A BOS DEP; FLT PLANNED VIA CTR. I HANDLED ACR X NORMALLY INCLUDING USING AN AUTOMATED INFO HDOF/XFER PROC WITH SECTOR 46. DURING THIS TIME; I RECEIVED A POINTOUT FROM SECTOR 36; THE GARDNER SECTOR; ON ACR Y; A MHT DEP ENRTE TO IAD. I APPROVED THE POINTOUT ON ACR Y FROM SECTOR 36 STATING IN MY APPROVAL; FL230. SHORTLY AFTER APPROVING THE POINTOUT ON ACR Y; I SAW THE INTERIM ALT OF FL230 HAD BEEN REMOVED FROM THE DATA BLOCK OF ACR Y; AND THAT THE ASSIGNED ALT OF FL280 WAS NOW DISPLAYED. I CALLED SECTOR 36 AND ASKED THEM TO ASSIGN FL230 TO ACR Y. IT WAS AGREED THAT ACR Y WOULD BE ISSUED FL230; AND THAT I WOULD WORK ACR Y. ACR Y CHKED ON MY FREQ; A SPD RESTR FOR SPACING TO IAD WAS ISSUED DUE TO TFC VIRTUALLY OVERHEAD ACR Y; ALSO ENRTE TO IAD. AS ACR Y APCHED ACR X; I ISSUED TFC. SHORTLY THEREAFTER; I OBSERVED ACR Y BEHIND ACR X AND AT FL233 OR THEREABOUTS; AND ASKED THE PLT TO VERIFY ALT. THE PLT STATED FL280. ACR Y HAD COMPLETELY DIVERGED FROM ACR X; AND PRESENTED NO FURTHER TFC THREAT. MY PRIORITY OF DUTY WAS TO INSURE SEPARATION BTWN ACR Y AND ACR Z; AN ACFT LATERALLY TO THE S OF ACR Y AND ABOVE ACR Y; AND TO INSURE THAT SECTOR 46 WAS AWARE THAT ACR Y WAS ABOVE ITS DISPLAYED INTERIM ALT.
