Narrative:

Being vectored for a visual approach to runway 4R, controller pointed out a 727 moving through 12 O'clock. Confirmed visual and were instructed to follow. Handed over to tower who inquired if we had the 727 in sight off our left. I responded there was a 737 off our left, the 727 was ahead. The 737 appeared to be heading for runway 4L. Tower responded that the traffic off our left was our sequence. Tower instructed us to fall in behind the 737. I responded a right 360 degree turn would do it and initiated the turn, noting on the TCASII that a company SF340 was on the approach behind us. They had been cleared for the visual to follow us to runway 4R. Passing through 180 degrees, RA to descend was issued, however, I had established visual with company by then and maintained visual throughout the maneuver. During this time, tower made several calls to company aircraft with no response from them. Once re-established on final, tower asked if we had company at 2 O'clock moving right to left. By then, company had re-established on final and was actually at our 11 O'clock. I responded that we had company in sight and would follow them to runway 4R. Once on the ground, I discussed the event with the other crew, who concurred with our version. They had maintained visual with us throughout the maneuver as well. I'm not sure where the 737 came into the picture. I don't recall hearing any radio xmissions until the tower cleared them to land. Approach idented our traffic as a 727 and the tower was also under the impression that a 727 was our sequence, the aircraft we were in fact following. Not until I idented the traffic off our left as a 737 were we instructed to follow them. To the best of my knowledge, no reports have been filed.

Title: MULTIPLE RWY OP VISUAL APCHS. ACR X HAD CONFLICT WITH TRAILING Y AFTER 360 DEG TURN.

Narrative: BEING VECTORED FOR A VISUAL APCH TO RWY 4R, CTLR POINTED OUT A 727 MOVING THROUGH 12 O'CLOCK. CONFIRMED VISUAL AND WERE INSTRUCTED TO FOLLOW. HANDED OVER TO TWR WHO INQUIRED IF WE HAD THE 727 IN SIGHT OFF OUR L. I RESPONDED THERE WAS A 737 OFF OUR L, THE 727 WAS AHEAD. THE 737 APPEARED TO BE HDG FOR RWY 4L. TWR RESPONDED THAT THE TFC OFF OUR L WAS OUR SEQUENCE. TWR INSTRUCTED US TO FALL IN BEHIND THE 737. I RESPONDED A R 360 DEG TURN WOULD DO IT AND INITIATED THE TURN, NOTING ON THE TCASII THAT A COMPANY SF340 WAS ON THE APCH BEHIND US. THEY HAD BEEN CLRED FOR THE VISUAL TO FOLLOW US TO RWY 4R. PASSING THROUGH 180 DEGS, RA TO DSND WAS ISSUED, HOWEVER, I HAD ESTABLISHED VISUAL WITH COMPANY BY THEN AND MAINTAINED VISUAL THROUGHOUT THE MANEUVER. DURING THIS TIME, TWR MADE SEVERAL CALLS TO COMPANY ACFT WITH NO RESPONSE FROM THEM. ONCE RE-ESTABLISHED ON FINAL, TWR ASKED IF WE HAD COMPANY AT 2 O'CLOCK MOVING R TO L. BY THEN, COMPANY HAD RE-ESTABLISHED ON FINAL AND WAS ACTUALLY AT OUR 11 O'CLOCK. I RESPONDED THAT WE HAD COMPANY IN SIGHT AND WOULD FOLLOW THEM TO RWY 4R. ONCE ON THE GND, I DISCUSSED THE EVENT WITH THE OTHER CREW, WHO CONCURRED WITH OUR VERSION. THEY HAD MAINTAINED VISUAL WITH US THROUGHOUT THE MANEUVER AS WELL. I'M NOT SURE WHERE THE 737 CAME INTO THE PICTURE. I DON'T RECALL HEARING ANY RADIO XMISSIONS UNTIL THE TWR CLRED THEM TO LAND. APCH IDENTED OUR TFC AS A 727 AND THE TWR WAS ALSO UNDER THE IMPRESSION THAT A 727 WAS OUR SEQUENCE, THE ACFT WE WERE IN FACT FOLLOWING. NOT UNTIL I IDENTED THE TFC OFF OUR L AS A 737 WERE WE INSTRUCTED TO FOLLOW THEM. TO THE BEST OF MY KNOWLEDGE, NO RPTS HAVE BEEN FILED.
