Narrative:

Holding pattern at bwz VOR at 14000 ft MSL. The other aircraft gulfstream (III or 4) was on a VFR climb, flying through our altitude as we initiated the outbound turn at the holding fix. Our TCASII issued a corrective RA. We maneuvered visually (gulfstream in sight), climbed approximately 800-900 ft, and avoided the traffic. ATC had issued a traffic alert call and both the captain and I saw the traffic. The corrective TCASII RA did not provide sufficient clearance because of the geometry of the turn in the holding pattern. ATC was advised of the TCASII evasive action.

Title: A VFR CLBING GIII CREATES A TCASII EVENT FOR A B737-800 IN THE HOLDING PATTERN AT BWZ, NJ.

Narrative: HOLDING PATTERN AT BWZ VOR AT 14000 FT MSL. THE OTHER ACFT GULFSTREAM (III OR 4) WAS ON A VFR CLB, FLYING THROUGH OUR ALT AS WE INITIATED THE OUTBOUND TURN AT THE HOLDING FIX. OUR TCASII ISSUED A CORRECTIVE RA. WE MANEUVERED VISUALLY (GULFSTREAM IN SIGHT), CLBED APPROX 800-900 FT, AND AVOIDED THE TFC. ATC HAD ISSUED A TFC ALERT CALL AND BOTH THE CAPT AND I SAW THE TFC. THE CORRECTIVE TCASII RA DID NOT PROVIDE SUFFICIENT CLRNC BECAUSE OF THE GEOMETRY OF THE TURN IN THE HOLDING PATTERN. ATC WAS ADVISED OF THE TCASII EVASIVE ACTION.
