ACFT #1 ENTERED CLASS C AIRSPACE WITHOUT COMMUNICATING WITH TRACON. RPTR STATES ACFT #1 WAS A HAZARD TO BOTH DEPARTING ACFT #2 AND ARRIVING ACFT AT CVG.

Narrative

OBSERVED A TARGET ON 1200 SQUAWK NNEBOUND AT 2400 FT INDICATED. ISSUED TFC TO DEPARTING B727 NOT KNOWING WHAT THE ACFT WAS GOING TO DO. CONTINUED TO TRACK TARGET AND RELAYED AN AUTOMATED POINTOUT/HDOF TO THE FINAL CTLR. ACFT TURNED EBOUND 8 MI N OF CVG ACROSS THE FINALS OF RWY R&L INTO CVG. RWY 18R ACFT ON FINAL WERE PASSING 500 FT OVERHEAD OF RWY 18L; ACFT APPROX 3800-3500 FT. I BELIEVE THAT THIS IS A PROB AND SAFETY ISSUE. ATC SHOULD BE TALKING TO THESE ACFT. ONE BECAUSE YOU DO NOT KNOW IF OR WHEN THIS PLT MAY BEGIN TO CLB (THROUGH A HOLE IN THE CLOUDS OR ENCOUNTERING HIGHER CEILINGS) THROUGH THE DEP RTES OR THE FINALS. I OBSERVED AN E120 AND CANADA REGIONAL JET (CARJ) THAT WERE IN CLOSE PROX TO THIS VFR ACFT ON FINAL TO RWY 18R. APPROX 1 - 1 1/2 MI HORIZ; 500 FT VERT; CLASS B AIRSPACE WOULD REQUIRE THESE INDIVIDUALS TO BE IN COM WITH ATC AND SAFETY TO THE FLYING PUBLIC AND THE PLT IN QUESTION WOULD THEN BE GUARANTEED. AS IT IS NOW; IT IS A BIT OF A CRAP SHOOT WHEN YOU ARE NOT IN COM WITH THE ONE ACFT THAT HAS THE POTENTIAL TO HAVE A GREAT IMPACT ON THE SIT AT HAND.
