WDB ON APCH HAS TCASII TA; RA THEN CLR.

Narrative

WE WERE DSNDING IN ACCORDANCE WITH OUR CLRNC FROM HNL APCH FROM 8000 FT TO 1500 FT ON A HDG OF ABOUT 220 DEGS (SLATS EXTENDED; SPOILERS; SPD BRAKES EXTENDED; 2000-3000 FPM; SPD 230 KIAS) WHEN WE RECEIVED; IN RAPID SUCCESSION (BEGINNING TO END APPROX 15 SECONDS) THE FOLLOWING RA'S FROM OUR TCASII: 1) REDUCE DSCNT; 2) CLB; CLB NOW; 3) CLR OF CONFLICT. AS I REACTED BY BRINGING THE NOSE OF THE ACFT UP; APCH ISSUED A TURN L TO 180 DEGS COINCIDENTAL WITH OUR TCASII VOICE RPT 'CLR OF CONFLICT.' AS I BEGAN THE L TURN; MY FO VISUALLY ACQUIRED A 737 (A DEP FROM HNL) TURNING AWAY TO OUR R. APCH ISSUED A R TURN TO 300 DEGS WHEREUPON WE SAW HNL ARPT AND WERE EVENTUALLY CLRED TO LAND ON RWY 4R. BEFORE THE ABOVE SEQUENCE OF EVENTS; WE WERE TALKING TO A CTLR WHO CLRED US FROM 10000 FT TO 8000 FT AND STATED THAT WE WOULD GET A LOWER ALT WHEN CLR OF THE ISLAND (OAHU). ABOUT 30 SECONDS AFTER XING THE SHORELINE; MY FO; AT MY DIRECTION; REQUESTED LOWER. NOW A DIFFERENT CTLR RESPONDED WITH CLRNC TO 1500 FT; NO HDG CHANGE INCLUDED. SHORTLY; THE ABOVE DESCRIBED RA'S TOOK PLACE. I SUSPECT THIS EVENT MAY HAVE OCCURRED PARTLY BECAUSE OF THE CTLR CHANGE. I DO KNOW THAT WE HAD NO OPPORTUNITY TO PICK UP THE ACFT VISUALLY THAT WAS CONVERGING WITH US FROM BEHIND AND BELOW. A LATER CONVERSATION VIA TELEPHONE WITH ATC PEOPLE IN HNL REVEALED THAT THEY HAD NO ALARMS GOING OFF AND NEITHER DID THE 737 CREW ACCORDING TO ATC WHO SAID THE 737 RPTED HE HAD US VISUALLY 'ALL THE TIME.' I DID NOT RPT THIS AS A NEAR MISS BECAUSE WHEN MY FO SAW THE 737; HE WAS FAR ENOUGH AWAY. NEVERTHELESS I DID HAVE AN RA ON MY TCASII AND SOMEWHERE THINGS BROKE DOWN ALLOWING US TO GET AT LEAST CLOSE ENOUGH FOR THAT.
