Narrative:
On feb/xa/00 while flying an airbus on approach to runway 19R to sna, we encountered 2 radar advisories while being vectored downwind for visual approach. During the first RA at approximately 7 mi northwest of field at 5000 ft, our TCASII directed a climb for separation. TCASII traffic passed under us by 500 ft. 2 mins later, we responded to another TCASII, directing a descent. Second TCASII traffic passed over us by 700 ft. Once we were clear of both RA's traffic, controller was advised of our altdevs. We were cleared by tower to turn right to a heading of 090 degrees at 4000 ft and cleared for the visual approach to runway 19R at sna. However, due to time of day, the sun and haze precluded a visual reference to runway 19R. Additionally, we were turned by controller too early and too high to affect a stabilized descent/approach. We initiated a go around at approximately 1800 ft AGL at 2.5 mi from runway. During the go around, while climbing to 3000 ft, we received a traffic alert from TCASII. The traffic was seen above and to the left of us, approximately 1000-2000 ft above. We responded to traffic alert and initiated a nose low descent to avoid traffic. Tower was notified of altitude deviation. In response to traffic conflict, we overspd flap speed by 10 KTS. Tower was advised about traffic. Tower's response was apologetic. We elected full ILS to runway 19R. Landing was uneventful. Aircraft maintenance was notified. Company was notified about approach conflicts and flap overspd. Aircraft returned to service following inspection of flaps. No other action taken.

Title: AIRBUS ON APCH TO SNA, CA, HAD 3 SEPARATE TCASII ADVISORS -- ONE GAR AND REFUSED A VISUAL APCH ACCOUNT LOW VISIBILITY IN HAZE.
Narrative: ON FEB/XA/00 WHILE FLYING AN AIRBUS ON APCH TO RWY 19R TO SNA, WE ENCOUNTERED 2 RADAR ADVISORIES WHILE BEING VECTORED DOWNWIND FOR VISUAL APCH. DURING THE FIRST RA AT APPROX 7 MI NW OF FIELD AT 5000 FT, OUR TCASII DIRECTED A CLB FOR SEPARATION. TCASII TFC PASSED UNDER US BY 500 FT. 2 MINS LATER, WE RESPONDED TO ANOTHER TCASII, DIRECTING A DSCNT. SECOND TCASII TFC PASSED OVER US BY 700 FT. ONCE WE WERE CLR OF BOTH RA'S TFC, CTLR WAS ADVISED OF OUR ALTDEVS. WE WERE CLRED BY TWR TO TURN R TO A HDG OF 090 DEGS AT 4000 FT AND CLRED FOR THE VISUAL APCH TO RWY 19R AT SNA. HOWEVER, DUE TO TIME OF DAY, THE SUN AND HAZE PRECLUDED A VISUAL REF TO RWY 19R. ADDITIONALLY, WE WERE TURNED BY CTLR TOO EARLY AND TOO HIGH TO AFFECT A STABILIZED DSCNT/APCH. WE INITIATED A GAR AT APPROX 1800 FT AGL AT 2.5 MI FROM RWY. DURING THE GAR, WHILE CLBING TO 3000 FT, WE RECEIVED A TFC ALERT FROM TCASII. THE TFC WAS SEEN ABOVE AND TO THE L OF US, APPROX 1000-2000 FT ABOVE. WE RESPONDED TO TFC ALERT AND INITIATED A NOSE LOW DSCNT TO AVOID TFC. TWR WAS NOTIFIED OF ALTDEV. IN RESPONSE TO TFC CONFLICT, WE OVERSPD FLAP SPD BY 10 KTS. TWR WAS ADVISED ABOUT TFC. TWR'S RESPONSE WAS APOLOGETIC. WE ELECTED FULL ILS TO RWY 19R. LNDG WAS UNEVENTFUL. ACFT MAINT WAS NOTIFIED. COMPANY WAS NOTIFIED ABOUT APCH CONFLICTS AND FLAP OVERSPD. ACFT RETURNED TO SVC FOLLOWING INSPECTION OF FLAPS. NO OTHER ACTION TAKEN.
