Narrative:
Aircraft #1 was on a practice approach to runway 5, aircraft #2 was departing the same runway opposite direction. Aircraft #1 was on approximately 10 mi final when aircraft #2 was cleared for takeoff. As local controller, I apprequed a right turn on course which was approved. His course differed from the inbound course of aircraft #1 by only 9 degrees instead of 45 degrees as required by the 7110.65 paragraph 6-1-3. I assumed that the jetstream would quickly outclb aircraft #1 and used this as my separation. I also assumed that because my request for on course with the radar controller was approved that he would issue TA's and/or radar vectors if needed to insure separation. Aircraft #2 asked the radar controller if he showed traffic for him which I assume was a result of TCASII. Contributing factors in this event are as follows: 1) my inexperience as a controller led me to thinking that the jetstream could outclb aircraft #1. 2) I put the responsibility of ensuring separation on another controller rather than myself. 3) I did not follow the procedures outlined in the 7110.65 paragraph 6-3-1.
Original NASA ASRS Text
Title: GRUMMAN ACFT IS INBOUND TO FWA ARPT ON A PRACTICE ILS APCH AND A JETSTREAM ACFT, AN IFR DEP, IS CLRED FOR TKOF ON SAME RWY OPPOSITE DIRECTION. ACFT CONFLICT 10 MI FROM THE ARPT RESULTING IN AN OPERROR.
Narrative: ACFT #1 WAS ON A PRACTICE APCH TO RWY 5, ACFT #2 WAS DEPARTING THE SAME RWY OPPOSITE DIRECTION. ACFT #1 WAS ON APPROX 10 MI FINAL WHEN ACFT #2 WAS CLRED FOR TKOF. AS LCL CTLR, I APPREQUED A R TURN ON COURSE WHICH WAS APPROVED. HIS COURSE DIFFERED FROM THE INBOUND COURSE OF ACFT #1 BY ONLY 9 DEGS INSTEAD OF 45 DEGS AS REQUIRED BY THE 7110.65 PARAGRAPH 6-1-3. I ASSUMED THAT THE JETSTREAM WOULD QUICKLY OUTCLB ACFT #1 AND USED THIS AS MY SEPARATION. I ALSO ASSUMED THAT BECAUSE MY REQUEST FOR ON COURSE WITH THE RADAR CTLR WAS APPROVED THAT HE WOULD ISSUE TA'S AND/OR RADAR VECTORS IF NEEDED TO INSURE SEPARATION. ACFT #2 ASKED THE RADAR CTLR IF HE SHOWED TFC FOR HIM WHICH I ASSUME WAS A RESULT OF TCASII. CONTRIBUTING FACTORS IN THIS EVENT ARE AS FOLLOWS: 1) MY INEXPERIENCE AS A CTLR LED ME TO THINKING THAT THE JETSTREAM COULD OUTCLB ACFT #1. 2) I PUT THE RESPONSIBILITY OF ENSURING SEPARATION ON ANOTHER CTLR RATHER THAN MYSELF. 3) I DID NOT FOLLOW THE PROCS OUTLINED IN THE 7110.65 PARAGRAPH 6-3-1.
