Narrative:

While working position D29 (leeon d-side) at atl ARTCC, R47 called at XX55.20 GMT to coordinate mdt X, a clt departure at 11000', direct lyh. This route would be head-on with clt arrs descending to 11000' on the majic STAR. I stated I would be unable direct lyh. R47 said mdt X would not stay on present heading and needed to turn east for WX avoidance. I told R47 to stand by, briefly discussed the situation with my r-side, then requested mdt X assigned heading 090 degrees. R47 stated that if mdt X could not fly an 015 degree heading, the aircraft would be on 090 degree heading. At XX56.56 GMT, sector 47 called and advised me that mdt X was turning right to an 090 degree heading. During the next 1 1/2 mins I attempted to call clt east arrival at least 3 times to find out what action they wanted us to take, if any, to separate mdt X from the arrs on the majic STAR. Mdt X crossed the arrival path and sep was lost between mdt X and medium large transport Y some time between XX58 and XX59 GMT. I felt that sector 47 (moped) should have coordinated with clt approach prior to reclring mdt X, and that clt approach would have specified how they wanted medium large transport Y cleared during that coordination. The incident occurred about 8-9 mi south of majic intersection at 11000', inside clt approach airspace. Supplemental information from acn 175217: the first conflicting inbound was an medium large transport Y at 11000'. The medium large transport Y was handed off to clt approach, but was never switched to clt approach. The 2 aircraft never responded to radio calls from clt approach. Both aircraft passed within 1 NM and less than 100' of each other. A second inbound was missed by 500' and 4.3 NM.

Title: MDT X DEVIATING FLR WX CAUSED A BREAKDOWN BETWEEN 2 ARTCC CTLRS WHICH RESULTED IN LESS THAN STANDARD SEPARATION BETWEEN A DEPARTING ACFT AND 2 INBOUND ACFT ON THE MAJIC STAR.

Narrative: WHILE WORKING POS D29 (LEEON D-SIDE) AT ATL ARTCC, R47 CALLED AT XX55.20 GMT TO COORDINATE MDT X, A CLT DEP AT 11000', DIRECT LYH. THIS RTE WOULD BE HEAD-ON WITH CLT ARRS DSNDING TO 11000' ON THE MAJIC STAR. I STATED I WOULD BE UNABLE DIRECT LYH. R47 SAID MDT X WOULD NOT STAY ON PRESENT HDG AND NEEDED TO TURN E FOR WX AVOIDANCE. I TOLD R47 TO STAND BY, BRIEFLY DISCUSSED THE SITUATION WITH MY R-SIDE, THEN REQUESTED MDT X ASSIGNED HDG 090 DEGS. R47 STATED THAT IF MDT X COULD NOT FLY AN 015 DEG HDG, THE ACFT WOULD BE ON 090 DEG HDG. AT XX56.56 GMT, SECTOR 47 CALLED AND ADVISED ME THAT MDT X WAS TURNING RIGHT TO AN 090 DEG HDG. DURING THE NEXT 1 1/2 MINS I ATTEMPTED TO CALL CLT E ARR AT LEAST 3 TIMES TO FIND OUT WHAT ACTION THEY WANTED US TO TAKE, IF ANY, TO SEPARATE MDT X FROM THE ARRS ON THE MAJIC STAR. MDT X CROSSED THE ARR PATH AND SEP WAS LOST BTWN MDT X AND MLG Y SOME TIME BTWN XX58 AND XX59 GMT. I FELT THAT SECTOR 47 (MOPED) SHOULD HAVE COORDINATED WITH CLT APCH PRIOR TO RECLRING MDT X, AND THAT CLT APCH WOULD HAVE SPECIFIED HOW THEY WANTED MLG Y CLRED DURING THAT COORD. THE INCIDENT OCCURRED ABOUT 8-9 MI S OF MAJIC INTXN AT 11000', INSIDE CLT APCH AIRSPACE. SUPPLEMENTAL INFO FROM ACN 175217: THE FIRST CONFLICTING INBND WAS AN MLG Y AT 11000'. THE MLG Y WAS HANDED OFF TO CLT APCH, BUT WAS NEVER SWITCHED TO CLT APCH. THE 2 ACFT NEVER RESPONDED TO RADIO CALLS FROM CLT APCH. BOTH ACFT PASSED WITHIN 1 NM AND LESS THAN 100' OF EACH OTHER. A SECOND INBND WAS MISSED BY 500' AND 4.3 NM.
