2 DC9'S OF THE SAME CARRIER HAVE A POTENTIAL CONFLICT AT FL250 NEAR THE FAR VOR; ND.

Narrative

WHILE CRUISING AT FL250 AND JUST AFTER XING FAR; WE TURNED TOWARDS THE 104 DEG RADIAL. PASSING THROUGH 096 DEG HDG; WE RECEIVED A TCASII ALERT (YELLOW TA); FOLLOWED SHORTLY AFTERWARD WITH A RED TCASII RA. TCASII INFORMED US TO DSND SO WE DID TOWARDS FL240. AT APPROX FL243 THE RA GAVE US A CLR OF CONFLICT. WE WERE REASSIGNED FL240 AND VECTORED SEVERELY (UP TO 90 DEG HDG CHANGE) TWICE TO PUT US BEHIND ANOTHER ACFT. I CALLED THE CTR AND TALKED TO A SUPVR; AND HE SEEMED TO INDICATE THAT WE; AS THE CREW; WERE NOT AT FAULT. THE ADVISORY NEVER LEFT THE EXTREME EDGE OF OUR TCASII SCREEN. WE DON'T BELIEVE THE OTHER ACFT CAME VERY CLOSE; AND THE EVENT SEEMED UNEVENTFUL BEYOND THE DSCNT. SUPPLEMENTAL INFO FROM ACN 486170: THE OTHER ACFT NEVER GOT CLOSER TO US THAN THE EDGE OF THE TCASII INDICATOR. THE OTHER PLANE WAS IN OUR 7-8 O'CLOCK POS; MOVING PERPENDICULAR TO OUR COURSE L TO R. SUPPLEMENTAL INFO FROM ACN 486432: ON CLBOUT THROUGH FL250 TO FL280; WE WERE CLRED BY ZMP TO MAINTAIN HDG 130 DEGS TO JOIN THE FAR 104 DEG RADIAL AND THE GEP 4 ARR TO MSP. CTR THEN ISSUED US A TA -- 12 O'CLOCK POS AND FL250 PASSING R TO L. CTR THEN GAVE US A HDG OF 160 DEGS FOR THE TFC. THEN WE GOT AN RA TO CLB. SINCE I HAD TFC IN SIGHT AND WE WERE IN A CLB THROUGH FL250; NO FURTHER EVASIVE ACTION WAS TAKEN.
