A B767 IN CURACAO AIRSPACE HAD A TCAS RA WITH ANOTHER ACFT; BOTH ASSIGNED TO FL330. ATC DID NOT RESPOND TO PREVIOUS CALLS FROM EITHER ACFT.

Narrative

AT APPROX XA30Z IN DARK CLR CONDITIONS; JUST PRIOR TO THE INTXN OF OUR AIRWAY; UL795; IN CURACAO AIRSPACE; THE TCAS SOUNDED A 'TFC; TFC' ALERT. THE TFC ON THE DISPLAY WAS CONVERGING FROM OUR R AT OUR ALT. I SPOTTED THE ACFT LIGHTS AND JUDGED HIS PATH TO BE A CONSTANT BEARING; DECREASING RANGE. THE TCAS A FEW SECONDS LATER SOUNDED A 'CLB; CLB' WARNING. THE CAPT SMOOTHLY RESPONDED TO THE TCAS COMMANDS. THE OTHER ACFT PASSED UNDER US WITH APPROX 1500 FT VERT SEPARATION; 1/4 MI LATERALLY. WE RETURNED TO FL330 AFTER CLR AND CONTACTED CURACAO. PRIOR TO ENTERING CURACAO AIRSPACE WE WERE IN KINGSTON AIRSPACE BTWN GELOG AND DIBOK FOR 20 MINS. JUST PAST THE MIDDLE OF THIS LEG WE RECEIVED CLRNC AND CLBED TO FL330. WE MADE REPEATED ATTEMPTS TO CONTACT CURACAO CTL; ALL NO JOY UNTIL AFTER THE RA; AS WAS THE CASE I BELIEVE FOR THE OTHER ACFT. THE CURACAO CTLR STATED THAT SHE THOUGHT WE WERE AT FL310. WE COORD TO REMAIN AT FL330. WE MADE 123.45 CONTACT WITH THE OTHER ACFT AND LEARNED THEY WERE FLYING AT THEIR ASSIGNED ALT. WE THEN CONTACTED DISPATCH. SUPPLEMENTAL INFO FROM ACN 733837: ACFT WAS PASSING FROM KINGSTON AIRSPACE TO CURACAO AIRSPACE AT FL330 IN CLR; NIGHT CONDITIONS. NEAR THE INTXN OF UL-395 AND A-319 (APPROX 75 NM S OF DIBOK) WE RECEIVED A TCAS ALERT. ONCE THE TA CHANGED TO AN RA; WE CLBED AND THE OTHER ACFT DSNDED. THE CLOSEST POINT OF APCH WAS .25 NM HORIZ AND 1000-1500 FT VERTICALLY. BOTH ACFT TOLD CURACAO ATC NEAR MISS RPTS WOULD BE FILED. OUR DISPATCHER WAS QUICKLY NOTIFIED ON SATCOM; NO INJURIES WERE INCURRED.
