Narrative:

Cleared direct to bxk. Level at 10000 MSL. Aircraft appeared on TCASII 12-1 O'clock position +300 ft. Advisory changed to resolution (descent) brought power to idle and descended to 9300 ft. Conflict ended as we began the descent. ATC gave us a clearance to climb to level FL210 and advised of traffic at 10000 ft. We advised we were descending in response to TCASII instruction. Controller had previously cleared other aircraft for a visual approach to goodyear airport. Controller appeared to think other aircraft was 500 ft above us and clear when he gave us the climb. I believe radar track may have been lagging aircraft position. Controller may have forgotten he had given other aircraft an approach clearance. We crossed behind and to left of other aircraft. Estimated distance 300 ft below and less than 1 mi horizontal. Other aircraft had continued his descent on visual approach and appeared to be unaware of us, as he took no evasive action. Had we climbed in response to controller's clearance, we would have had a near miss or possible collision.

Original NASA ASRS Text

Title: AN A319 CREW, DEPARTING PHX, RECEIVED AND RESPONDED TO A DESCEND RA FROM TCASII.

Narrative: CLRED DIRECT TO BXK. LEVEL AT 10000 MSL. ACFT APPEARED ON TCASII 12-1 O'CLOCK POS +300 FT. ADVISORY CHANGED TO RESOLUTION (DSCNT) BROUGHT PWR TO IDLE AND DESCENDED TO 9300 FT. CONFLICT ENDED AS WE BEGAN THE DSCNT. ATC GAVE US A CLRNC TO CLB TO LEVEL FL210 AND ADVISED OF TFC AT 10000 FT. WE ADVISED WE WERE DESCENDING IN RESPONSE TO TCASII INSTRUCTION. CTLR HAD PREVIOUSLY CLRED OTHER ACFT FOR A VISUAL APCH TO GOODYEAR ARPT. CTLR APPEARED TO THINK OTHER ACFT WAS 500 FT ABOVE US AND CLR WHEN HE GAVE US THE CLB. I BELIEVE RADAR TRACK MAY HAVE BEEN LAGGING ACFT POS. CTLR MAY HAVE FORGOTTEN HE HAD GIVEN OTHER ACFT AN APCH CLRNC. WE CROSSED BEHIND AND TO L OF OTHER ACFT. ESTIMATED DISTANCE 300 FT BELOW AND LESS THAN 1 MI HORIZ. OTHER ACFT HAD CONTINUED HIS DSCNT ON VISUAL APCH AND APPEARED TO BE UNAWARE OF US, AS HE TOOK NO EVASIVE ACTION. HAD WE CLIMBED IN RESPONSE TO CTLR'S CLRNC, WE WOULD HAVE HAD A NEAR MISS OR POSSIBLE COLLISION.
