Narrative:

I was working in cmh TRACON at the time of the events. A developmental who is certified on final position was working final. The developmental's supervisor was watching from another scope. There was an inbound rush and the developmental was directly responsible for no less than 4 sets (8 aircraft) losing separation within a 15 min period. The closest 2 sets were air carrier X (medium large transport) and Y (medium large transport) also air carrier a and air carrier B. Both sets were at the same altitude, with about 1 mi separation. Later in the evening the same developmental on the same position, with the same supervisor watching, lost separation with 2 other air carrier's. The supervisor observed the whole series of events and took no action. This supervisor certified this developmental on all positions (they are personal friends) against several recommendations and obviously did not want to take responsibility for the separation errors. I feel this type of situation could be remedied with the use of fpl controllers from opposite crews doing evaluations and certification of developmentals.

Title: LESS THAN STANDARD SEPARATION BETWEEN ACR X AND Y. ACR A AND B. SYSTEM ERROR. SITUATION: CTLR CERTIFICATION PROC.

Narrative: I WAS WORKING IN CMH TRACON AT THE TIME OF THE EVENTS. A DEVELOPMENTAL WHO IS CERTIFIED ON FINAL POSITION WAS WORKING FINAL. THE DEVELOPMENTAL'S SUPVR WAS WATCHING FROM ANOTHER SCOPE. THERE WAS AN INBND RUSH AND THE DEVELOPMENTAL WAS DIRECTLY RESPONSIBLE FOR NO LESS THAN 4 SETS (8 ACFT) LOSING SEPARATION WITHIN A 15 MIN PERIOD. THE CLOSEST 2 SETS WERE ACR X (MLG) AND Y (MLG) ALSO ACR A AND ACR B. BOTH SETS WERE AT THE SAME ALT, WITH ABOUT 1 MI SEPARATION. LATER IN THE EVENING THE SAME DEVELOPMENTAL ON THE SAME POSITION, WITH THE SAME SUPVR WATCHING, LOST SEPARATION WITH 2 OTHER ACR'S. THE SUPVR OBSERVED THE WHOLE SERIES OF EVENTS AND TOOK NO ACTION. THIS SUPVR CERTIFIED THIS DEVELOPMENTAL ON ALL POSITIONS (THEY ARE PERSONAL FRIENDS) AGAINST SEVERAL RECOMMENDATIONS AND OBVIOUSLY DID NOT WANT TO TAKE RESPONSIBILITY FOR THE SEPARATION ERRORS. I FEEL THIS TYPE OF SITUATION COULD BE REMEDIED WITH THE USE OF FPL CTLRS FROM OPPOSITE CREWS DOING EVALUATIONS AND CERTIFICATION OF DEVELOPMENTALS.
