FOR THE SECOND ATTEMPT THE PILOT WAS CLEARED FOR A FULL APCH FOR ILS RWY 23; WHICH REQUIRED A PROCEDURE TURN. THE PILOT LAST POSITION REPORT WAS INBOUND ON THE LOCALIZER COURSE. SHORTLY AFTERWARDS, THE PILOT WAS CLEARED TO SWITCH OVER TO THE AIRPORT UNICOM FREQ. RADAR DATA ON THE ACFT SHOWS THAT THE ACFT REACHED OVER THE O/M AND BEGAN TO FLY TOWARD THE WEST.
