Narrative:

Approaching tvc for landing we were told by tvc tower that our traffic for 28 was on 1 mi final. At the time we were at 2200' MSL (1500' AGL) on a left base when we noticed an small aircraft pass 300' under us from right to left. The small aircraft was on a 280-300 degree heading inside the air traffic area. Tvc tower never advised us of the traffic, only that they knew an small aircraft had reported 15 mi southeast and was told to report the VOR. For all purposes it appeared that the small aircraft in question was entering a right downwind for runway 10. Before there is a midair collision at tvc, 2 things needs to be done: 1) move the tvc VOR to the airport. At the present time the VOR is outside the air traffic area and aircraft are holding, tracking, etc west/O knowledge of tvc ATC. At the same time tvc tower uses tvc VOR as a funnel, telling aircraft to report the VOR. 2) extend the control zone to cover the LOM for the ILS 28 approach. At the present time aircraft will be practicing holding at the LOM west/O knowledge of tvc ATC, in MVFR conditions with aircraft on IFR approachs to ILS 28. Tvc has quite a bit of air traffic, including training. The ideal solution would be the establishment of a TRSA at tvc.

Title: CLOSE PROX ACR-MDT GA-SMA 4 MILES SOUTHEAST OF TVC.

Narrative: APCHING TVC FOR LNDG WE WERE TOLD BY TVC TWR THAT OUR TFC FOR 28 WAS ON 1 MI FINAL. AT THE TIME WE WERE AT 2200' MSL (1500' AGL) ON A LEFT BASE WHEN WE NOTICED AN SMA PASS 300' UNDER US FROM RIGHT TO LEFT. THE SMA WAS ON A 280-300 DEG HDG INSIDE THE ATA. TVC TWR NEVER ADVISED US OF THE TFC, ONLY THAT THEY KNEW AN SMA HAD RPTED 15 MI SE AND WAS TOLD TO RPT THE VOR. FOR ALL PURPOSES IT APPEARED THAT THE SMA IN QUESTION WAS ENTERING A RIGHT DOWNWIND FOR RWY 10. BEFORE THERE IS A MIDAIR COLLISION AT TVC, 2 THINGS NEEDS TO BE DONE: 1) MOVE THE TVC VOR TO THE ARPT. AT THE PRESENT TIME THE VOR IS OUTSIDE THE ATA AND ACFT ARE HOLDING, TRACKING, ETC W/O KNOWLEDGE OF TVC ATC. AT THE SAME TIME TVC TWR USES TVC VOR AS A FUNNEL, TELLING ACFT TO RPT THE VOR. 2) EXTEND THE CTL ZONE TO COVER THE LOM FOR THE ILS 28 APCH. AT THE PRESENT TIME ACFT WILL BE PRACTICING HOLDING AT THE LOM W/O KNOWLEDGE OF TVC ATC, IN MVFR CONDITIONS WITH ACFT ON IFR APCHS TO ILS 28. TVC HAS QUITE A BIT OF AIR TFC, INCLUDING TRNING. THE IDEAL SOLUTION WOULD BE THE ESTABLISHMENT OF A TRSA AT TVC.
