Narrative:
Air carrier X climbed out of rdu, climbing to 11000 ft. Aircraft was climbed to 13000 ft. Air carrier Y was on rdu departure also. Air carrier Y appeared to be tracking outbound on the fay 2 departure. Rdu departure turned air carrier Y hard left to join the rozbo departure transition. Air carrier Y was at 12000 ft, air carrier X was out of 12000 ft. I tried to effect coordination with rdu departure to turn the aircraft. Was advised aircraft was on center frequency. Air carrier Y checked in at 12000 ft, was turned to a 230 degree heading and was given expedited climb to 13000 ft. I did not receive the strip on air carrier Y. I assumed the aircraft would continue south on the fay 6 transition. Also a factor was the gray area of the rdu/ZDC LOA which states center has control to climb aircraft 5 NM south of rdu VOR. Rdu controller saw the situation developing and did nothing to help resolve the situation.
Original NASA ASRS Text
Title: THE SECOND OF SUCCESSIVE DEPS OFF RDU WAS ALLOWED TO OVERTAKE THE LEADING ACFT RESULTING IN A LOSS OF SEPARATION.
Narrative: ACR X CLBED OUT OF RDU, CLBING TO 11000 FT. ACFT WAS CLBED TO 13000 FT. ACR Y WAS ON RDU DEP ALSO. ACR Y APPEARED TO BE TRACKING OUTBOUND ON THE FAY 2 DEP. RDU DEP TURNED ACR Y HARD L TO JOIN THE ROZBO DEP TRANSITION. ACR Y WAS AT 12000 FT, ACR X WAS OUT OF 12000 FT. I TRIED TO EFFECT COORD WITH RDU DEP TO TURN THE ACFT. WAS ADVISED ACFT WAS ON CTR FREQ. ACR Y CHKED IN AT 12000 FT, WAS TURNED TO A 230 DEG HDG AND WAS GIVEN EXPEDITED CLB TO 13000 FT. I DID NOT RECEIVE THE STRIP ON ACR Y. I ASSUMED THE ACFT WOULD CONTINUE S ON THE FAY 6 TRANSITION. ALSO A FACTOR WAS THE GRAY AREA OF THE RDU/ZDC LOA WHICH STATES CTR HAS CTL TO CLB ACFT 5 NM S OF RDU VOR. RDU CTLR SAW THE SIT DEVELOPING AND DID NOTHING TO HELP RESOLVE THE SIT.
