Narrative:

On approach to runway 27R to mia airport my flight was vectored 110 degrees or 120 degrees. ATC then gave us a vector to turn left to 270 degrees. I took to be a mistake by the controller and waited a few xmissions to get back to him and clarify. When we did clarify he then said turn left again to 240 degrees now. I then questioned the direction of the turn because I thought we should have been given a right turn because we were northeast of the airport. He then replied that I was right to turn right to 240 degrees. Going through 180 degrees we noticed a B767 on the approach at our 10 O'clock position. The controller then told us to turn immediately to 090 degrees. Then rescinded that clearance and told us to fly south. He did point out traffic to both of us and both had visual contact with each other. We flew under the B767 on a 180 degree heading then given a 270 degree turn left to rejoin the final approach. He then admitted that he had made a mistake and since we had visual with each other nothing else need be done and I agree. I believe that the controller initially wanted us to turn to 090 degrees and was confused with the direction when he issued left to 270 degrees. In hindsight, this would have solved the problem.

Original NASA ASRS Text

Title: NMAC.

Narrative: ON APCH TO RWY 27R TO MIA ARPT MY FLT WAS VECTORED 110 DEGS OR 120 DEGS. ATC THEN GAVE US A VECTOR TO TURN L TO 270 DEGS. I TOOK TO BE A MISTAKE BY THE CTLR AND WAITED A FEW XMISSIONS TO GET BACK TO HIM AND CLARIFY. WHEN WE DID CLARIFY HE THEN SAID TURN L AGAIN TO 240 DEGS NOW. I THEN QUESTIONED THE DIRECTION OF THE TURN BECAUSE I THOUGHT WE SHOULD HAVE BEEN GIVEN A R TURN BECAUSE WE WERE NE OF THE ARPT. HE THEN REPLIED THAT I WAS RIGHT TO TURN R TO 240 DEGS. GOING THROUGH 180 DEGS WE NOTICED A B767 ON THE APCH AT OUR 10 O'CLOCK POS. THE CTLR THEN TOLD US TO TURN IMMEDIATELY TO 090 DEGS. THEN RESCINDED THAT CLRNC AND TOLD US TO FLY S. HE DID POINT OUT TFC TO BOTH OF US AND BOTH HAD VISUAL CONTACT WITH EACH OTHER. WE FLEW UNDER THE B767 ON A 180 DEG HDG THEN GIVEN A 270 DEG TURN L TO REJOIN THE FINAL APCH. HE THEN ADMITTED THAT HE HAD MADE A MISTAKE AND SINCE WE HAD VISUAL WITH EACH OTHER NOTHING ELSE NEED BE DONE AND I AGREE. I BELIEVE THAT THE CTLR INITIALLY WANTED US TO TURN TO 090 DEGS AND WAS CONFUSED WITH THE DIRECTION WHEN HE ISSUED L TO 270 DEGS. IN HINDSIGHT, THIS WOULD HAVE SOLVED THE PROB.
