Narrative:
Climb out from pvd (providence, ri) airport, wbound to put. At 4000 ft, climbing 3000 FPM, got a TCASII advisory showing an aircraft 1500 ft above us and 2 1/2 mi in front of us approaching. Began a power reduction. At 4500 ft got a TCASII resolution and I immediately leveled off at 4500 ft. Resolution showed aircraft approaching 1000 ft above us, less than 2 mi. Got a visual contact with aircraft. He went almost right over us at 5500 ft MSL. We were level at 4500 ft MSL. Asked pvd departure control 3 times if they had traffic in our area and they said no targets. I believe TCASII saved us from a very close call! ATC never had the other aircraft, though he must have had his transponder on or we would not have had a TCASII resolution.

Narrative: CLBOUT FROM PVD (PROVIDENCE, RI) ARPT, WBOUND TO PUT. AT 4000 FT, CLBING 3000 FPM, GOT A TCASII ADVISORY SHOWING AN ACFT 1500 FT ABOVE US AND 2 1/2 MI IN FRONT OF US APCHING. BEGAN A PWR REDUCTION. AT 4500 FT GOT A TCASII RESOLUTION AND I IMMEDIATELY LEVELED OFF AT 4500 FT. RESOLUTION SHOWED ACFT APCHING 1000 FT ABOVE US, LESS THAN 2 MI. GOT A VISUAL CONTACT WITH ACFT. HE WENT ALMOST RIGHT OVER US AT 5500 FT MSL. WE WERE LEVEL AT 4500 FT MSL. ASKED PVD DEP CTL 3 TIMES IF THEY HAD TFC IN OUR AREA AND THEY SAID NO TARGETS.
