POTENTIAL CONFLICT OCCURS DURING A NIGHT OP BEFORE A B717-200 FLC ON A VISUAL TO RWY 34 PERFORMS A SLIGHT CLB FOR EVASIVE ACTION DUE TO THE CLOSURE RATE OF A XING A319 MAKING AN APCH TO RWY 2 AT RIC; VA.

Narrative

WE REQUESTED AN APCH TO RWY 34 AT RIC. APCH CTL VECTORED US TO THE S OF RIC TO INTERCEPT RWY 34 CTRLINE. WHEN APCHING THE RWY 2 CTRLINE (ABOUT 3 NM S OF RWY); APCH CTL RPTED TFC AT 12 O'CLOCK POS AND HIGH FOR RWY 34 (THAT TFC WAS TO FOLLOW US) AND 2 O'CLOCK POS FOR RWY 2. WE ACKNOWLEDGED THAT WE HAD BOTH AIRPLANES AND WERE CLRED FOR A VISUAL APCH TO RWY 34. WE INITIATED A DSCNT AND VACATED 3000 FT MSL FOR 1700 FT MSL WITH A SLIGHT L TURN TO INTERCEPT RWY 34; JUST INSIDE KAFKA (OM). OUR CLOSURE ON THE A319 (LNDG ON RWY 2) APPEARED TO BE TOO TIGHT; SO WE INITIATED A CLB BACK TO 3000 FT. AS WE STARTED THE CLB; WE GOT AN RA TO FIRST 'MONITOR VERT SPD;' QUICKLY FOLLOWED BY A 'CLB' ALERT. THE ALERT ENDED AT ABOUT 3200 FT MSL. WE HAD A VISUAL WITH THE A319 DURING THE ENTIRE MANEUVER. THE REST OF THE APCH WAS NORMAL. A319 THOUGHT WE WERE MAKING A L TURN FOR RWY 2 AND TERMINATED THEIR APCH FOR RWY 2 WITH A R TURN TO THE E; THUS INCREASING THE CLOSURE RATE BTWN US. LONG DUTY DAY AND UNFAMILIAR WITH RIC ARPT AND AREA. SUPPLEMENTAL INFO FROM ACN 537939: I REQUESTED RWY 34 AS I HAD NEVER BEEN TO RIC BEFORE. WHEN ABEAM THE EXTENDED CTRLINE OF RWY 2; I LOST SIGHT OF THE ACFT ON APCH FOR RWY 2 MOMENTARILY. AGAIN REGAINING VISUAL; I STARTED DSCNT FOR GSIA ON RWY 30. FACTORS: UNFAMILIAR WITH ARPT; FATIGUE: 12 HR DUTY DAY; 7.3 HRS FLYING TIME; MISCOM WITH FO.
