Narrative:

Small transport X executed a missed approach on the ILS runway 36 approach. Small aircraft Y was issued a clearance to maintain 3000, cleared for ILS runway 36 approach. Small transport X was climbed to 3000, present heading, which he reported as 040 degrees. When small transport X was asked his position, he reported 10 NM northwest of the airport. I turned him to a heading of 180, to aim him back at the localizer. At this time, I did not have radar contact on him. I assumed that he was sufficiently west of the localizer. I acquired radar contact over the approach fix, head-on to small aircraft Y, less than 2 mi at the same altitude. I asked small transport X to climb expeditiously to 4000, and he complied. Neither pilot reported seeing the other. It is status quo for controllers to assume the duties of rfd approach on the midnight shift, however, I was neither trained nor certified to work the airspace.

Title: SMT X HAD LTSS FROM SMA Y. SAME ALT ASSIGNED. SYS ERROR.

Narrative: SMT X EXECUTED A MISSED APCH ON THE ILS RWY 36 APCH. SMA Y WAS ISSUED A CLRNC TO MAINTAIN 3000, CLRED FOR ILS RWY 36 APCH. SMT X WAS CLBED TO 3000, PRESENT HDG, WHICH HE RPTED AS 040 DEGS. WHEN SMT X WAS ASKED HIS POS, HE RPTED 10 NM NW OF THE ARPT. I TURNED HIM TO A HDG OF 180, TO AIM HIM BACK AT THE LOC. AT THIS TIME, I DID NOT HAVE RADAR CONTACT ON HIM. I ASSUMED THAT HE WAS SUFFICIENTLY W OF THE LOC. I ACQUIRED RADAR CONTACT OVER THE APCH FIX, HEAD-ON TO SMA Y, LESS THAN 2 MI AT THE SAME ALT. I ASKED SMT X TO CLB EXPEDITIOUSLY TO 4000, AND HE COMPLIED. NEITHER PLT RPTED SEEING THE OTHER. IT IS STATUS QUO FOR CTLRS TO ASSUME THE DUTIES OF RFD APCH ON THE MIDNIGHT SHIFT, HOWEVER, I WAS NEITHER TRAINED NOR CERTIFIED TO WORK THE AIRSPACE.
