Narrative:

First officer was flying on approach ILS runway 22L in visual conditions. Upon contacting tower outside ayron (30-45 seconds before TA event), was advised by tower helicopter traffic at 800 ft would pass right to left and would maintain visual separation from us. Approximately 1200 ft AGL at speed vref +15 KTS and slowing, on course, on GS, we received a TA with traffic shown converging from right 400 ft below. At approximately 1000 ft RA was received with voice 'monitor vertical speed' and indications directing no further descent. We leveled off going 1 1/2 dots above GS. Helicopter passed directly below us at 300 ft then 200 ft immediately after passing. We never visually acquired the traffic. Had we not leveled off, would have experienced an near midair collision, with less than 100 ft separation. We were able to recover the GS and approach was stabilized and uneventful below 500 ft AGL. Contacted tower on the event. Seriously question the helicopter pilot's adherence to safe separation distances.

Title: TFC SEPARATION NOT MAINTAINED ON ILS FINAL AT EWR, NJ.

Narrative: FO WAS FLYING ON APCH ILS RWY 22L IN VISUAL CONDITIONS. UPON CONTACTING TWR OUTSIDE AYRON (30-45 SECONDS BEFORE TA EVENT), WAS ADVISED BY TWR HELI TFC AT 800 FT WOULD PASS R TO L AND WOULD MAINTAIN VISUAL SEPARATION FROM US. APPROX 1200 FT AGL AT SPD VREF +15 KTS AND SLOWING, ON COURSE, ON GS, WE RECEIVED A TA WITH TFC SHOWN CONVERGING FROM R 400 FT BELOW. AT APPROX 1000 FT RA WAS RECEIVED WITH VOICE 'MONITOR VERT SPD' AND INDICATIONS DIRECTING NO FURTHER DSCNT. WE LEVELED OFF GOING 1 1/2 DOTS ABOVE GS. HELI PASSED DIRECTLY BELOW US AT 300 FT THEN 200 FT IMMEDIATELY AFTER PASSING. WE NEVER VISUALLY ACQUIRED THE TFC. HAD WE NOT LEVELED OFF, WOULD HAVE EXPERIENCED AN NMAC, WITH LESS THAN 100 FT SEPARATION. WE WERE ABLE TO RECOVER THE GS AND APCH WAS STABILIZED AND UNEVENTFUL BELOW 500 FT AGL. CONTACTED TWR ON THE EVENT. SERIOUSLY QUESTION THE HELI PLT'S ADHERENCE TO SAFE SEPARATION DISTANCES.
