Narrative:

We had crossed over chardon VOR at 9000 ft and then we were told to descend to 7000 ft. Approximately 30 seconds later the approach control gave us a traffic warning. He said traffic was at our 12:30-1 O'clock at 8500. At that time we were at 8600 ft and saw the traffic approximately 100 ft and to the right of our nose. I was the first officer and it was my leg so I immediately pulled the nose up to stop the descent and climbed back over the traffic. The other aircraft may or may not have been in contact with approach. He was right on the edge of the TCA. The controller made no more comments about the traffic to us in any form. The WX was good VFR clear, 15 mi visibility, sun was getting low but was not a factor. I believe the controller failed to provide separation between us and traffic.

Title: FLC OF LTT ON DSCNT PASSED IN CLOSE PROX TO VFR SMT.

Narrative: WE HAD CROSSED OVER CHARDON VOR AT 9000 FT AND THEN WE WERE TOLD TO DSND TO 7000 FT. APPROX 30 SECONDS LATER THE APCH CTL GAVE US A TFC WARNING. HE SAID TFC WAS AT OUR 12:30-1 O'CLOCK AT 8500. AT THAT TIME WE WERE AT 8600 FT AND SAW THE TFC APPROX 100 FT AND TO THE R OF OUR NOSE. I WAS THE FO AND IT WAS MY LEG SO I IMMEDIATELY PULLED THE NOSE UP TO STOP THE DSCNT AND CLBED BACK OVER THE TFC. THE OTHER ACFT MAY OR MAY NOT HAVE BEEN IN CONTACT WITH APCH. HE WAS RIGHT ON THE EDGE OF THE TCA. THE CTLR MADE NO MORE COMMENTS ABOUT THE TFC TO US IN ANY FORM. THE WX WAS GOOD VFR CLR, 15 MI VISIBILITY, SUN WAS GETTING LOW BUT WAS NOT A FACTOR. I BELIEVE THE CTLR FAILED TO PROVIDE SEPARATION BTWN US AND TFC.
