Narrative:

After checking in with ocean approach at 10000' MSL, approximately 40 DME southwest of the pvd VOR, we were given a descent clearance to 7000' with a left turn direct to pvd VOR. Ocean approach immediately returned with a traffic advisory at 1 mi at 10000' MSL. We (all crew members) began a scan after checking altimeters. I observed an small transport approximately 12:30 position on a perpendicular collision course. I pointed out the traffic and the captain performed an escape maneuver to small transport high 6 O'clock. Once clear of traffic, ocean approach notified us that the small transport was VFR. Altimeter setting on the pvd ATIS was 30.33, our airspeed was 250 KTS, heading approximately 150 degree magnetic at time of occurrence.

Title: CLOSE PROX ACR-LGT GA-SMA 40 NORTHEAST OF PVD.

Narrative: AFTER CHKING IN WITH OCEAN APCH AT 10000' MSL, APPROX 40 DME SW OF THE PVD VOR, WE WERE GIVEN A DSCNT CLRNC TO 7000' WITH A LEFT TURN DIRECT TO PVD VOR. OCEAN APCH IMMEDIATELY RETURNED WITH A TFC ADVISORY AT 1 MI AT 10000' MSL. WE (ALL CREW MEMBERS) BEGAN A SCAN AFTER CHKING ALTIMETERS. I OBSERVED AN SMT APPROX 12:30 POS ON A PERPENDICULAR COLLISION COURSE. I POINTED OUT THE TFC AND THE CAPT PERFORMED AN ESCAPE MANEUVER TO SMT HIGH 6 O'CLOCK. ONCE CLR OF TFC, OCEAN APCH NOTIFIED US THAT THE SMT WAS VFR. ALTIMETER SETTING ON THE PVD ATIS WAS 30.33, OUR AIRSPD WAS 250 KTS, HDG APPROX 150 DEG MAGNETIC AT TIME OF OCCURRENCE.
