Narrative:

On dallas 7 departure in contact with ZFW. Given a climb clearance to 370 and to be out of 350 within 5 mins. We complied easily. Out of 360 for 370, center said to turn left 10 degrees. We complied. Less than 1 min later, center said to turn left 30 degrees and that we had turned right instead of left. Center instructed other traffic to turn left 30 degrees as well. Our crew verified that we turned left both times as instructed and I believe that the controller allowed the conflict to occur due to his error. Copilot visually sighted the traffic off to the right.

Title: POTENTIAL CONFLICT LTSS WITH LOSS OF SEPARATION.

Narrative: ON DALLAS 7 DEP IN CONTACT WITH ZFW. GIVEN A CLB CLRNC TO 370 AND TO BE OUT OF 350 WITHIN 5 MINS. WE COMPLIED EASILY. OUT OF 360 FOR 370, CTR SAID TO TURN L 10 DEGS. WE COMPLIED. LESS THAN 1 MIN LATER, CTR SAID TO TURN L 30 DEGS AND THAT WE HAD TURNED R INSTEAD OF L. CTR INSTRUCTED OTHER TFC TO TURN L 30 DEGS AS WELL. OUR CREW VERIFIED THAT WE TURNED L BOTH TIMES AS INSTRUCTED AND I BELIEVE THAT THE CTLR ALLOWED THE CONFLICT TO OCCUR DUE TO HIS ERROR. COPLT VISUALLY SIGHTED THE TFC OFF TO THE R.
