Narrative:

Aircraft #1 departed dtw on 260 degree heading, aircraft #2 was cleared for a visual approach right traffic for runway 23L (coming from southwest). Yip tower cleared him to runway 27L and he turned eastbound to downwind left traffic for runway 27L right at aircraft #1 who was climbing slow as he was unpressurized. There is a serious problem with unpressurized aircraft departing wswbound and yip's class D airspace. Also with yip LOA and their having control to circle south of yip for runway 27 with dtw propeller departures. Callback conversation with reporter revealed the following information: reporter stated aircraft #2, an arrival on a visual approach to yip, was released to the tower approximately 10 mi from the airport. At about the same time, dtw automatic-released aircraft #1, a slow clber, towards yip. Yip tower, on initial contact with aircraft #2, changed the assigned runway and instructed the pilot to circle to a different runway that conflicted with the departure off dtw. Reporter claims the LOA between the TRACON and yip should be changed to keep the controllers from circling traffic south of yip unless coordinated. Reporter admitted he allowed his trainee to release the visual arrival too soon to the tower. Reporter said he had filed 3 ucr's when this incident occurred.

Title: DTW AND YIP ARPTS ARE APPROX 8 MI APART. RPTR CLAIMS SLOW CLBING ACFT FROM DTW CAN EASILY CONFLICT WITH TFC AT YIP.

Narrative: ACFT #1 DEPARTED DTW ON 260 DEG HDG, ACFT #2 WAS CLRED FOR A VISUAL APCH R TFC FOR RWY 23L (COMING FROM SW). YIP TWR CLRED HIM TO RWY 27L AND HE TURNED EBOUND TO DOWNWIND L TFC FOR RWY 27L RIGHT AT ACFT #1 WHO WAS CLBING SLOW AS HE WAS UNPRESSURIZED. THERE IS A SERIOUS PROB WITH UNPRESSURIZED ACFT DEPARTING WSWBOUND AND YIP'S CLASS D AIRSPACE. ALSO WITH YIP LOA AND THEIR HAVING CTL TO CIRCLE S OF YIP FOR RWY 27 WITH DTW PROP DEPS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED ACFT #2, AN ARR ON A VISUAL APCH TO YIP, WAS RELEASED TO THE TWR APPROX 10 MI FROM THE ARPT. AT ABOUT THE SAME TIME, DTW AUTO-RELEASED ACFT #1, A SLOW CLBER, TOWARDS YIP. YIP TWR, ON INITIAL CONTACT WITH ACFT #2, CHANGED THE ASSIGNED RWY AND INSTRUCTED THE PLT TO CIRCLE TO A DIFFERENT RWY THAT CONFLICTED WITH THE DEP OFF DTW. RPTR CLAIMS THE LOA BTWN THE TRACON AND YIP SHOULD BE CHANGED TO KEEP THE CTLRS FROM CIRCLING TFC S OF YIP UNLESS COORDINATED. RPTR ADMITTED HE ALLOWED HIS TRAINEE TO RELEASE THE VISUAL ARR TOO SOON TO THE TWR. RPTR SAID HE HAD FILED 3 UCR'S WHEN THIS INCIDENT OCCURRED.
