An IFR arrival into LDJ was questioned regarding a conflict involving a EWR arrival and entry into class B airspace. The reporter noted compliance with FAR's; wind conditions; and Controller instructions contributed to the event.

Narrative

I departed on an IFR flight plan to Linden; NJ (LDJ). I requested the GPS A approach at LDJ. I informed ATC of my intention to cancel IFR at BAUTZ intersection. The Controller stated that I would need to cancel IFR before turning right at BAUTZ to enter the pattern at LDJ. As I crossed the BAUTZ intersection the Controller; using non-standard phraseology; stated 'now or never.' I felt pressure to cancel IFR and canceled to comply with his request. The Controller was busy and somewhat agitated and; although he did not say so; I considered a clearance into Bravo implicit with the IFR cancellation since I was less than two minutes from entering the Newark class B. The wind at Newark was 290 degrees at 10 KTS. I entered a downwind for Runway 27 at 1;000 FT MSL; 200 FT above the Class B floor in that area. This Controller did not inform me of any conflicting traffic before hastily acknowledging my cancellation. FAR 91.119(b) requires a minimum altitude of 1;000 FT AGL above congested/ populated areas. Upon landing; the FBO asked me to call the Newark Tower. I was told an incoming jet to Newark's Runway 04 complained about me and that they would have to do an investigation. This event was isolated; inadvertent; and I was not informed of any loss of separation.
