Narrative:

ZNY called traffic at 10 O'clock, 5 mi. I was PNF. I indicated negative contact, one at 11 O'clock -- he pointed him out. PF pointed to him, so I 'figured' he had the traffic. I indicated to ARTCC we had visual contact (we saw his landing lights blazing). ARTCC said maintain visual separation and I think something to the effect of descending him through our altitude, we were cleared to climb. Closing quickly, we got a TCASII TA but I still believed the PF had traffic. He was hand flying, not using autoplt, so attention was inside more than outside. I didn't get a definitive response. Then TCASII RA 'descend, descend' aircraft was 1/2 mi, 200 ft above. The captain kept climbing, looking out window, then turning right. I kept asking 'you got him?' he was off left side, so I could not see. All I saw was TCASII showing +02, +01, 00! And target was right on our miniature airplane symbol. By this time, he had pulled the power levers to flight idle! That's it. I didn't know if he had the traffic or not, so I pushed the yoke until we got a good descent going and I saw +01, +02, +03, then let off the yoke pressure. Later he told me he didn't even feel me do that. Accident was avoided -- too close, though. He said he was angry since he 'never' calls traffic to ATC. That's their job. To some degree, I agree, but we saw the other aircraft. But my mistake was calling traffic and accepting visual separation without captain's concurrence. I will ask future pilots that I fly with how they wish to handle ATC TA's. As a note: PF (captain) said 'I'm bad luck things happen to me (what the %$#@ is that?) he took no proactive action. I had to push the yoke my human factor I mentioned his is apparent.

Title: A DEHAVILLAND DASH 8 HAD AN NMAC NEAR HAR.

Narrative: ZNY CALLED TFC AT 10 O'CLOCK, 5 MI. I WAS PNF. I INDICATED NEGATIVE CONTACT, ONE AT 11 O'CLOCK -- HE POINTED HIM OUT. PF POINTED TO HIM, SO I 'FIGURED' HE HAD THE TFC. I INDICATED TO ARTCC WE HAD VISUAL CONTACT (WE SAW HIS LNDG LIGHTS BLAZING). ARTCC SAID MAINTAIN VISUAL SEPARATION AND I THINK SOMETHING TO THE EFFECT OF DSNDING HIM THROUGH OUR ALT, WE WERE CLRED TO CLB. CLOSING QUICKLY, WE GOT A TCASII TA BUT I STILL BELIEVED THE PF HAD TFC. HE WAS HAND FLYING, NOT USING AUTOPLT, SO ATTN WAS INSIDE MORE THAN OUTSIDE. I DIDN'T GET A DEFINITIVE RESPONSE. THEN TCASII RA 'DSND, DSND' ACFT WAS 1/2 MI, 200 FT ABOVE. THE CAPT KEPT CLBING, LOOKING OUT WINDOW, THEN TURNING R. I KEPT ASKING 'YOU GOT HIM?' HE WAS OFF L SIDE, SO I COULD NOT SEE. ALL I SAW WAS TCASII SHOWING +02, +01, 00! AND TARGET WAS RIGHT ON OUR MINIATURE AIRPLANE SYMBOL. BY THIS TIME, HE HAD PULLED THE PWR LEVERS TO FLT IDLE! THAT'S IT. I DIDN'T KNOW IF HE HAD THE TFC OR NOT, SO I PUSHED THE YOKE UNTIL WE GOT A GOOD DSCNT GOING AND I SAW +01, +02, +03, THEN LET OFF THE YOKE PRESSURE. LATER HE TOLD ME HE DIDN'T EVEN FEEL ME DO THAT. ACCIDENT WAS AVOIDED -- TOO CLOSE, THOUGH. HE SAID HE WAS ANGRY SINCE HE 'NEVER' CALLS TFC TO ATC. THAT'S THEIR JOB. TO SOME DEG, I AGREE, BUT WE SAW THE OTHER ACFT. BUT MY MISTAKE WAS CALLING TFC AND ACCEPTING VISUAL SEPARATION WITHOUT CAPT'S CONCURRENCE. I WILL ASK FUTURE PLTS THAT I FLY WITH HOW THEY WISH TO HANDLE ATC TA'S. AS A NOTE: PF (CAPT) SAID 'I'M BAD LUCK THINGS HAPPEN TO ME (WHAT THE %$#@ IS THAT?) HE TOOK NO PROACTIVE ACTION. I HAD TO PUSH THE YOKE MY HUMAN FACTOR I MENTIONED HIS IS APPARENT.
