Narrative:
Slc bearr arrival, after ogd VOR cleared heading 130 degrees to intercept runway 17 localizer, cleared visual approach to runway 17. Outside of tiful intersection slowed to 170 KTS, cleared to tower frequency, cleared to land runway 17. Tower asked if we had runway 16L in sight, affirmative. Cleared to land runway 16L. At approximately 7 NM out, turned towards runway 16L and my TCASII warning showed an aircraft at 3 O'clock position very close. Received a climb resolution. The 3 O'clock position traffic (cessna) was visual, slightly high. I elected to return towards runway 17 and requested landing clearance. I then saw a light airplane on short left base turning to final to runway 17, below and ahead of us. I elected to go around and stated our decision on the frequency. Received no reply from tower for some time after receiving clearance to land on runway 16L. However, I did hear tower talking to other aircraft. After executing the go around, tower gave us directions of runway heading and 8000 ft. Supplemental information from acn 387115: air carrier X was cleared for approach to runway 17 at slc. Cleared to slow to 170 KTS and contact tower about 12 mi out. Tower controller asked us if we could see runway 16L. We answered affirmative, he cleared us to land on runway 16L. As we were sliding over to the extended centerline of runway 16L, a cessna citation was directly abeam us, apparently also lined up for a runway 16L approach. While trying to clarify the situation, we were parallel to the cessna and received a TCASII RA, advising us to climb. With the traffic in sight and slightly above us in altitude, we turned slightly left to increase horizontal separation. Communicated with tower that it appeared the cessna was lined up with runway 16L and that we were going back toward runway 17. No response was received immediately from tower, and when we saw a small civil aircraft, type unknown, on a turn to final for runway 17, we elected to climb and fly the missed approach. Apparently the cessna citation was also given a climb/missed approach instructions, as we heard the controller attempting to contact him, with no response heard from the aircraft. Perhaps citation was still on approach frequency or other tower frequency. Rest of flight, vectored around to approach for runway 16R, was uneventful.
Original NASA ASRS Text
Title: B727 WAS CLRED TO LAND SLC RWY 17. TWR REQUESTED ACR TO CHANGE TO RWY 16L. AS ACR BEGAN SIDESTEP MANEUVER, PIC OBSERVED CONVERGING CESSNA JET APPEARING TO LINE UP TO RWY 16L. PIC QUERIED TWR ABOUT TFC AND RECEIVED A TCASII TA. PIC MANEUVERED BACK TOWARDS RWY 17 AND RECEIVED A TCASII RA FROM OTHER UNKNOWN TFC OBSERVED ON BASE LEG FOR RWY 17. PIC EXECUTED GAR.
Narrative: SLC BEARR ARR, AFTER OGD VOR CLRED HDG 130 DEGS TO INTERCEPT RWY 17 LOC, CLRED VISUAL APCH TO RWY 17. OUTSIDE OF TIFUL INTXN SLOWED TO 170 KTS, CLRED TO TWR FREQ, CLRED TO LAND RWY 17. TWR ASKED IF WE HAD RWY 16L IN SIGHT, AFFIRMATIVE. CLRED TO LAND RWY 16L. AT APPROX 7 NM OUT, TURNED TOWARDS RWY 16L AND MY TCASII WARNING SHOWED AN ACFT AT 3 O'CLOCK POS VERY CLOSE. RECEIVED A CLB RESOLUTION. THE 3 O'CLOCK POS TFC (CESSNA) WAS VISUAL, SLIGHTLY HIGH. I ELECTED TO RETURN TOWARDS RWY 17 AND REQUESTED LNDG CLRNC. I THEN SAW A LIGHT AIRPLANE ON SHORT L BASE TURNING TO FINAL TO RWY 17, BELOW AND AHEAD OF US. I ELECTED TO GAR AND STATED OUR DECISION ON THE FREQ. RECEIVED NO REPLY FROM TWR FOR SOME TIME AFTER RECEIVING CLRNC TO LAND ON RWY 16L. HOWEVER, I DID HEAR TWR TALKING TO OTHER ACFT. AFTER EXECUTING THE GAR, TWR GAVE US DIRECTIONS OF RWY HEADING AND 8000 FT. SUPPLEMENTAL INFO FROM ACN 387115: ACR X WAS CLRED FOR APCH TO RWY 17 AT SLC. CLRED TO SLOW TO 170 KTS AND CONTACT TWR ABOUT 12 MI OUT. TWR CTLR ASKED US IF WE COULD SEE RWY 16L. WE ANSWERED AFFIRMATIVE, HE CLRED US TO LAND ON RWY 16L. AS WE WERE SLIDING OVER TO THE EXTENDED CTRLINE OF RWY 16L, A CESSNA CITATION WAS DIRECTLY ABEAM US, APPARENTLY ALSO LINED UP FOR A RWY 16L APCH. WHILE TRYING TO CLARIFY THE SIT, WE WERE PARALLEL TO THE CESSNA AND RECEIVED A TCASII RA, ADVISING US TO CLB. WITH THE TFC IN SIGHT AND SLIGHTLY ABOVE US IN ALT, WE TURNED SLIGHTLY L TO INCREASE HORIZ SEPARATION. COMMUNICATED WITH TWR THAT IT APPEARED THE CESSNA WAS LINED UP WITH RWY 16L AND THAT WE WERE GOING BACK TOWARD RWY 17. NO RESPONSE WAS RECEIVED IMMEDIATELY FROM TWR, AND WHEN WE SAW A SMALL CIVIL ACFT, TYPE UNKNOWN, ON A TURN TO FINAL FOR RWY 17, WE ELECTED TO CLB AND FLY THE MISSED APCH. APPARENTLY THE CESSNA CITATION WAS ALSO GIVEN A CLB/MISSED APCH INSTRUCTIONS, AS WE HEARD THE CTLR ATTEMPTING TO CONTACT HIM, WITH NO RESPONSE HEARD FROM THE ACFT. PERHAPS CITATION WAS STILL ON APCH FREQ OR OTHER TWR FREQ. REST OF FLT, VECTORED AROUND TO APCH FOR RWY 16R, WAS UNEVENTFUL.
