Narrative:
C172 departed airport, was turned northbound off runway 15. Tower then cleared an AC69 off runways and tried to turn it north inside the C172. The AC69 climbed quickly to 2000 ft before the tower descended it back to 1500 ft. By then, according to the C172, the AC69 'almost t-boned' the C172. The C172 called after landing at alliance airport (afw) to report an near midair collision. I think the problem was that the tower tried to outrun the C172 by having the AC69 turn immediately (according to the C172 pilot, the AC69 turned before the end of the runway). The AC69 couldn't see the C172 because he was in a steep turn and climbing. I was very busy working numerous other aircraft and didn't see the confliction and the tower held onto the AC69 until they felt the situation was resolved.
Original NASA ASRS Text
Title: AN AC69 ALMOST COLLIDES WITH DEP C172 THAT WAS IN A TURN 1 MI E OF ADS, TX.
Narrative: C172 DEPARTED ARPT, WAS TURNED NBOUND OFF RWY 15. TWR THEN CLRED AN AC69 OFF RWYS AND TRIED TO TURN IT N INSIDE THE C172. THE AC69 CLBED QUICKLY TO 2000 FT BEFORE THE TWR DSNDED IT BACK TO 1500 FT. BY THEN, ACCORDING TO THE C172, THE AC69 'ALMOST T-BONED' THE C172. THE C172 CALLED AFTER LNDG AT ALLIANCE ARPT (AFW) TO RPT AN NMAC. I THINK THE PROB WAS THAT THE TWR TRIED TO OUTRUN THE C172 BY HAVING THE AC69 TURN IMMEDIATELY (ACCORDING TO THE C172 PLT, THE AC69 TURNED BEFORE THE END OF THE RWY). THE AC69 COULDN'T SEE THE C172 BECAUSE HE WAS IN A STEEP TURN AND CLBING. I WAS VERY BUSY WORKING NUMEROUS OTHER ACFT AND DIDN'T SEE THE CONFLICTION AND THE TWR HELD ONTO THE AC69 UNTIL THEY FELT THE SIT WAS RESOLVED.
