Flying IFR proceeding direct to the airport on a clearance from N90 approach. We had slowed to 200 KTS. Approach asked for a further reduction to 170 KTS for spacing. Although the ATIS said 3 mi or better, the visibility at altitude was much less due to haze. Multiple VFR targets were pointed out to us at 2 O'clock and 9 O'clock positions. We did not see the traffic. The first officer returned his attention to the radar checklist. I returned my scan to straight ahead. Very suddenly I saw a white twin engine aircraft ahead. I grabbed the yoke and pulled up. The aircraft passed below. ATC said there was no primary or secondary target. A few seconds later they said a target appeared at our 6 O'clock at 2500' (500' below us). It is my opinion that the twin was skirting the TCA--a few ft below the 3000' base with his transponder off. Had we ben at a higher speed or a few ft lower, I don't think I would be here to write this. TCA's would have been a great help. Heads out of the cockpit and slow speeds in the approach area are the only defense to such unprofessional and dangerous wkend fliers who fly VFR in marginal WX in a TCA environment with no transponder.
Original NASA ASRS Text
Title: CORP ACFT HAS NMAC WITH TWIN DURING APCH.
Narrative: FLYING IFR PROCEEDING DIRECT TO THE ARPT ON A CLRNC FROM N90 APCH. WE HAD SLOWED TO 200 KTS. APCH ASKED FOR A FURTHER REDUCTION TO 170 KTS FOR SPACING. ALTHOUGH THE ATIS SAID 3 MI OR BETTER, THE VISIBILITY AT ALT WAS MUCH LESS DUE TO HAZE. MULTIPLE VFR TARGETS WERE POINTED OUT TO US AT 2 O'CLOCK AND 9 O'CLOCK POSITIONS. WE DID NOT SEE THE TFC. THE F/O RETURNED HIS ATTN TO THE RADAR CHKLIST. I RETURNED MY SCAN TO STRAIGHT AHEAD. VERY SUDDENLY I SAW A WHITE TWIN ENG ACFT AHEAD. I GRABBED THE YOKE AND PULLED UP. THE ACFT PASSED BELOW. ATC SAID THERE WAS NO PRIMARY OR SECONDARY TARGET. A FEW SECS LATER THEY SAID A TARGET APPEARED AT OUR 6 O'CLOCK AT 2500' (500' BELOW US). IT IS MY OPINION THAT THE TWIN WAS SKIRTING THE TCA--A FEW FT BELOW THE 3000' BASE WITH HIS XPONDER OFF. HAD WE BEN AT A HIGHER SPD OR A FEW FT LOWER, I DON'T THINK I WOULD BE HERE TO WRITE THIS. TCA'S WOULD HAVE BEEN A GREAT HELP. HEADS OUT OF THE COCKPIT AND SLOW SPDS IN THE APCH AREA ARE THE ONLY DEFENSE TO SUCH UNPROFESSIONAL AND DANGEROUS WKEND FLIERS WHO FLY VFR IN MARGINAL WX IN A TCA ENVIRONMENT WITH NO XPONDER.
