Cpr X, an light transport, was descending into cle on V14 when he asked me if I saw traffic for him moving west to east. At first I didn't see him, then as the data block moved on, I saw a primary target and I told cpr X about it. Cpr X explained that he believed it was a fixed winged small aircraft that passed close by and surprised him. When I asked the pilot what altitude the VFR aircraft was at, he estimated between 13,000 and 14,000'. The pilot then asked that we track the aircraft and send him a letter because he was flying above 10,000' without transponder or mode C. As far as I know, no evasive actions were needed, however, I feel that it was a dangerous situation. At the time, the cle clearance delivery was down.
Original NASA ASRS Text
Title: ACFT FLT ABOVE 10,000' WITHOUT TRANSPONDER AND MODE C. PLT DEVIATION.
Narrative: CPR X, AN LTT, WAS DESCENDING INTO CLE ON V14 WHEN HE ASKED ME IF I SAW TFC FOR HIM MOVING W TO E. AT FIRST I DIDN'T SEE HIM, THEN AS THE DATA BLOCK MOVED ON, I SAW A PRIMARY TARGET AND I TOLD CPR X ABOUT IT. CPR X EXPLAINED THAT HE BELIEVED IT WAS A FIXED WINGED SMA THAT PASSED CLOSE BY AND SURPRISED HIM. WHEN I ASKED THE PLT WHAT ALT THE VFR ACFT WAS AT, HE ESTIMATED BETWEEN 13,000 AND 14,000'. THE PLT THEN ASKED THAT WE TRACK THE ACFT AND SEND HIM A LETTER BECAUSE HE WAS FLYING ABOVE 10,000' WITHOUT XPONDER OR MODE C. AS FAR AS I KNOW, NO EVASIVE ACTIONS WERE NEEDED, HOWEVER, I FEEL THAT IT WAS A DANGEROUS SITUATION. AT THE TIME, THE CLE CD WAS DOWN.
