Narrative:

While approaching cincinnati airport for a landing on runway 36R, we were instructed by cvg approach control to descend from 6000 ft to 5000 ft and turn to a heading of 340 degrees to intercept the cvg runway 36R localizer. During the turn and descent we received a TCASII TA, followed by a TCASII RA. The RA advised an immediate 2500 FPM rate of climb on the TA vsi. The PF, me, had a positive visual on the conflicting traffic. It appeared that the B767 was climbing and turning into us. My visual instinct was to turn away and descend, thus keeping the aircraft in sight. However, we followed the TCASII advisory and climbed and turned aggressively. ATC was advised that we were taking evasive maneuvers. There seemed to be a long pause before any acknowledgment was given. We were attempting to return to 5000 ft when we were told to climb to 6000 ft and turn to 090 degrees. During this maneuver we received an additional TCASII TA to monitor vertical speed. This event ended quickly. Remainder of approach and landing was uneventful. Approach control supervisor, after contact, stated this was an error by approach control. Supplemental information from acn 391578: we aggressively climbed according to the TCASII command and avoided the other jet.

Title: RPTED LOSS OF SEPARATION BTWN DSNDING ACR B727 AND A CLBING ACR B767.

Narrative: WHILE APCHING CINCINNATI ARPT FOR A LNDG ON RWY 36R, WE WERE INSTRUCTED BY CVG APCH CTL TO DSND FROM 6000 FT TO 5000 FT AND TURN TO A HDG OF 340 DEGS TO INTERCEPT THE CVG RWY 36R LOC. DURING THE TURN AND DSCNT WE RECEIVED A TCASII TA, FOLLOWED BY A TCASII RA. THE RA ADVISED AN IMMEDIATE 2500 FPM RATE OF CLB ON THE TA VSI. THE PF, ME, HAD A POSITIVE VISUAL ON THE CONFLICTING TFC. IT APPEARED THAT THE B767 WAS CLBING AND TURNING INTO US. MY VISUAL INSTINCT WAS TO TURN AWAY AND DSND, THUS KEEPING THE ACFT IN SIGHT. HOWEVER, WE FOLLOWED THE TCASII ADVISORY AND CLBED AND TURNED AGGRESSIVELY. ATC WAS ADVISED THAT WE WERE TAKING EVASIVE MANEUVERS. THERE SEEMED TO BE A LONG PAUSE BEFORE ANY ACKNOWLEDGMENT WAS GIVEN. WE WERE ATTEMPTING TO RETURN TO 5000 FT WHEN WE WERE TOLD TO CLB TO 6000 FT AND TURN TO 090 DEGS. DURING THIS MANEUVER WE RECEIVED AN ADDITIONAL TCASII TA TO MONITOR VERT SPD. THIS EVENT ENDED QUICKLY. REMAINDER OF APCH AND LNDG WAS UNEVENTFUL. APCH CTL SUPVR, AFTER CONTACT, STATED THIS WAS AN ERROR BY APCH CTL. SUPPLEMENTAL INFO FROM ACN 391578: WE AGGRESSIVELY CLBED ACCORDING TO THE TCASII COMMAND AND AVOIDED THE OTHER JET.
