Narrative:

The regional jet was on an instrument (ILS 35) approach to cwa at 3000 ft. The skylane was on a parallel route inbound to auw at 4000 ft. The skylane reported the airport in sight (I think after radar contact was lost). He was cleared to maintain 4000 ft until the VOR and then cleared for the visual approach. He lost the airport but said he had it again visually. I asked him if he could maintain the airport visually and he said yes. I again cleared him for the visual approach and changed him to advisory frequency. The next transmission was the skylane saying he had made a mistake and had tried to land at the wrong airport. Cwa tower then called and said the skylane tried to land while the regional jet was landing. Both aircraft were below radar coverage and I'm not sure how close they came to each other.

Title: ZMP CTLR DESCRIBED EVENT WHEN ACFT CLRED FOR VIS APCH TO AUW INITIATED APCH TO CWA; POSSIBLY CONFLICTING WITH CRJ ARR.

Narrative: THE REGIONAL JET WAS ON AN INST (ILS 35) APCH TO CWA AT 3000 FT. THE SKYLANE WAS ON A PARALLEL RTE INBOUND TO AUW AT 4000 FT. THE SKYLANE RPTED THE ARPT IN SIGHT (I THINK AFTER RADAR CONTACT WAS LOST). HE WAS CLRED TO MAINTAIN 4000 FT UNTIL THE VOR AND THEN CLRED FOR THE VISUAL APCH. HE LOST THE ARPT BUT SAID HE HAD IT AGAIN VISUALLY. I ASKED HIM IF HE COULD MAINTAIN THE ARPT VISUALLY AND HE SAID YES. I AGAIN CLRED HIM FOR THE VISUAL APCH AND CHANGED HIM TO ADVISORY FREQ. THE NEXT XMISSION WAS THE SKYLANE SAYING HE HAD MADE A MISTAKE AND HAD TRIED TO LAND AT THE WRONG ARPT. CWA TWR THEN CALLED AND SAID THE SKYLANE TRIED TO LAND WHILE THE REGIONAL JET WAS LNDG. BOTH ACFT WERE BELOW RADAR COVERAGE AND I'M NOT SURE HOW CLOSE THEY CAME TO EACH OTHER.
