Airspace Structure; Human Factors
Inbound to ZELEN IAF; New York Approach cleared us for RNAV Runway 5 approach to MMU. After crossing ZELEN at 3;000 FT; Approach handed us off to MMU Tower. While on the approach segment from ZELEN to KWITE at 3;000 FT; TCAS alerted us to traffic at our altitude. There was no warning other than the RA command to climb; which we immediately initiated; climbing to approximately 3;400 FT. We saw a single engine aircraft pass directly beneath us. I notified MMU tower of our RA. As we leveled at 3;400 FT and started a return to 3;000 FT; a Falcon crossed our path at 4;000 FT. We resumed the approach to MMU Runway 05. I contacted TRACON after parking. TRACON indicated that the conflict traffic was a VFR aircraft; not under their control. Our aircraft lighting was configured to be seen. We had position lights; beacon; strobes and pulse lights all operating.
A BD700 Captain reported a NMAC with a light aircraft that was not in contact with ATC on approach to MMU.
