Narrative:

I was the approach controller working traffic in and out of efd. Light transport was inbound to efd from the north. I called eft controller with the inbound and requested runway 22 which was not approved because of MTR in the traffic pattern to runway 4. I cleared light transport for a visibility approach to runway 4. I didn't switch him to tower because I was waiting for him to get below other traffic that was overflying. While I was waiting for the altitude, I got busy with other traffic and forgot to switch the light transport to efd. Light transport called when he was abeam efd and asked if he should switch to tower frequency. I said yes, to contact tower 126.2. The light transport and MTR got too close to each other. Callback conversation with reporter revealed the following: reporter does not know how close the aircraft came together. He was in progress of briefing the relieving controller when the incident occurred. The relieving controller was the person who changed the frequency of the light transport when the tower controller asked to talk to the light transport. The MTR had been worked by the approach controller and changed to the tower. The MTR stayed in the traffic pattern making touch and go lndgs. The approach controller called the light transport to the tower before it entered the air traffic area. Tower did not inform the approach controller of any pertinent traffic.

Title: APCH CTLR FORGOT TO CHANGE FREQ ON THE LTT IN SUFFICIENT TIME SO THAT THE ATCT LCL CTLR COULD ISSUE TRAFFIC TO THE LTT FLT CREW. THE RESULT WAS THE LTT CAME VERY CLOSE TO THE MTR IN THE TRAFFIC PATTERN.

Narrative: I WAS THE APCH CTLR WORKING TFC IN AND OUT OF EFD. LTT WAS INBND TO EFD FROM THE N. I CALLED EFT CTLR WITH THE INBND AND REQUESTED RWY 22 WHICH WAS NOT APPROVED BECAUSE OF MTR IN THE TFC PATTERN TO RWY 4. I CLRED LTT FOR A VIS APCH TO RWY 4. I DIDN'T SWITCH HIM TO TWR BECAUSE I WAS WAITING FOR HIM TO GET BELOW OTHER TFC THAT WAS OVERFLYING. WHILE I WAS WAITING FOR THE ALT, I GOT BUSY WITH OTHER TFC AND FORGOT TO SWITCH THE LTT TO EFD. LTT CALLED WHEN HE WAS ABEAM EFD AND ASKED IF HE SHOULD SWITCH TO TWR FREQ. I SAID YES, TO CONTACT TWR 126.2. THE LTT AND MTR GOT TOO CLOSE TO EACH OTHER. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR DOES NOT KNOW HOW CLOSE THE ACFT CAME TOGETHER. HE WAS IN PROGRESS OF BRIEFING THE RELIEVING CTLR WHEN THE INCIDENT OCCURRED. THE RELIEVING CTLR WAS THE PERSON WHO CHANGED THE FREQ OF THE LTT WHEN THE TWR CTLR ASKED TO TALK TO THE LTT. THE MTR HAD BEEN WORKED BY THE APCH CTLR AND CHANGED TO THE TWR. THE MTR STAYED IN THE TFC PATTERN MAKING TOUCH AND GO LNDGS. THE APCH CTLR CALLED THE LTT TO THE TWR BEFORE IT ENTERED THE ATA. TWR DID NOT INFORM THE APCH CTLR OF ANY PERTINENT TFC.
