Narrative:
Working local combined at mia airport. I departed a heavy DC8 off the south parallel runway (runway 9R) on a 090 degree heading. I was supposed to put him on a 120 degree heading, but forgot to turn him due to traffic. Moments later, I departed a beech 1900 off runway 9L on a 105 degree heading, thinking that I had turned the DC8 to 120 degrees. B190 passed less than 1 mi behind DC8. I had already switched both aircraft to departure and had no control over the situation. After scanning the runways, I looked at the BRITE radar and noticed the B190 passing behind the DC8. Thank god that no one was hurt. I requested time off after this incident due to emotional stress. Cause could only be blamed on human error. In this case -- mine.

Title: MIA LCL CTLR DID NOT INSURE WAKE TURB SEPARATION WHEN HE DEPARTED A B190 BEHIND A HVY DC8 THAT HAD DEPARTED A PARALLEL RWY.
Narrative: WORKING LCL COMBINED AT MIA ARPT. I DEPARTED A HVY DC8 OFF THE S PARALLEL RWY (RWY 9R) ON A 090 DEG HDG. I WAS SUPPOSED TO PUT HIM ON A 120 DEG HDG, BUT FORGOT TO TURN HIM DUE TO TFC. MOMENTS LATER, I DEPARTED A BEECH 1900 OFF RWY 9L ON A 105 DEG HDG, THINKING THAT I HAD TURNED THE DC8 TO 120 DEGS. B190 PASSED LESS THAN 1 MI BEHIND DC8. I HAD ALREADY SWITCHED BOTH ACFT TO DEP AND HAD NO CTL OVER THE SIT. AFTER SCANNING THE RWYS, I LOOKED AT THE BRITE RADAR AND NOTICED THE B190 PASSING BEHIND THE DC8. THANK GOD THAT NO ONE WAS HURT. I REQUESTED TIME OFF AFTER THIS INCIDENT DUE TO EMOTIONAL STRESS. CAUSE COULD ONLY BE BLAMED ON HUMAN ERROR. IN THIS CASE -- MINE.
