Narrative:

I was performing my duties as the area supervisor on duty in the shu RAPCON. I heard dtw tower request release off runway 5 for small transport. The controller said to hold and then he coordinated with the radar east coordinator. If radar east coordinator said an immediate right turn to 160 degrees reference an light transport. The radar south controller released small transport with the turn and dtw tower said show him rolling. At this time the radar east controller turned a flight of fgt's to a base leg. I then asked the radar south controller what the status was of small transport and his reply was that he was rolling. I then informed the radar east controller that there was an small transport released off runway 5 at dtw and he was rolling. I also told him that this traffic situation would work out. It didn't. Bad airport had a VFR kcio in their pattern, which is approximately 4 mi southeast of dtw. The dtw local controller issued the kcio as traffic and instructed him to maintain visibility sep and to turn to 160 degrees when able. The small transport did not begin his turn until 4 northeast of dtw and we could not talk to him because dtw had not put him on our frequency. In the meantime the fgt's were turned onto final and changed to bad tower. When it became evident that small transport was not turning as instructed or anticipated the fgt's were issued a heading by the radar east controller away from small transport using 243.0 frequency. We lost standard sep and filed a system error report with the FAA.

Title: LAST MINUTE CHANGES TO DEP CLRNC AND LATE CHANGE FREQ CHANGE TO DEP CTL RESULTED IN LESS THAN STANDARD SEPARATION BETWEEN SMT AND 2 FGT'S.

Narrative: I WAS PERFORMING MY DUTIES AS THE AREA SUPVR ON DUTY IN THE SHU RAPCON. I HEARD DTW TWR REQUEST RELEASE OFF RWY 5 FOR SMT. THE CTLR SAID TO HOLD AND THEN HE COORDINATED WITH THE RADAR E COORDINATOR. IF RADAR E COORDINATOR SAID AN IMMEDIATE RIGHT TURN TO 160 DEGS REF AN LTT. THE RADAR S CTLR RELEASED SMT WITH THE TURN AND DTW TWR SAID SHOW HIM ROLLING. AT THIS TIME THE RADAR E CTLR TURNED A FLT OF FGT'S TO A BASE LEG. I THEN ASKED THE RADAR S CTLR WHAT THE STATUS WAS OF SMT AND HIS REPLY WAS THAT HE WAS ROLLING. I THEN INFORMED THE RADAR E CTLR THAT THERE WAS AN SMT RELEASED OFF RWY 5 AT DTW AND HE WAS ROLLING. I ALSO TOLD HIM THAT THIS TFC SITUATION WOULD WORK OUT. IT DIDN'T. BAD ARPT HAD A VFR KCIO IN THEIR PATTERN, WHICH IS APPROX 4 MI SE OF DTW. THE DTW LCL CTLR ISSUED THE KCIO AS TFC AND INSTRUCTED HIM TO MAINTAIN VIS SEP AND TO TURN TO 160 DEGS WHEN ABLE. THE SMT DID NOT BEGIN HIS TURN UNTIL 4 NE OF DTW AND WE COULD NOT TALK TO HIM BECAUSE DTW HAD NOT PUT HIM ON OUR FREQ. IN THE MEANTIME THE FGT'S WERE TURNED ONTO FINAL AND CHANGED TO BAD TWR. WHEN IT BECAME EVIDENT THAT SMT WAS NOT TURNING AS INSTRUCTED OR ANTICIPATED THE FGT'S WERE ISSUED A HDG BY THE RADAR E CTLR AWAY FROM SMT USING 243.0 FREQ. WE LOST STANDARD SEP AND FILED A SYS ERROR RPT WITH THE FAA.
