Air Traffic Incident | Operational Error |
Narrative:
IFR C421 climbing south. I radar idented him and climbed him to 7000 ft and shipped him to dag. Dag did not climb aircraft. I had a twin VFR off hnd. I idented him and cleared him through class B airspace; told him to maintain at or below 7000 ft. I did not realize C421 had not been issued a climb. The conflict alert went off and I was not receiving mode C from the twin. I asked the twin his altitude. He said 6600 ft. I told him to maintain that and there will be an E120 passing overhead. Prior to this instance; I was extremely busy on this position and was going on my fifth hour on position for the day. For the amount of traffic worked that day (on sundays) that is a long time to be on position and had I not had that error; I would have worked 6 hours. I believe fatigue played a factor in this error. Too much traffic; bad procedures at the facility; and gross understaffing will continue to lead to errors at L30.

Title: L30 CTLR EXPERIENCED OPERROR AT 7000 FT IN CLASS B AIRSPACE WITH IFR DEP AND VFR ACFT AFTER FAILING TO RECOGNIZE THAT ADJACENT CTLR DID NOT CLB IFR ACFT.
Narrative: IFR C421 CLBING S. I RADAR IDENTED HIM AND CLBED HIM TO 7000 FT AND SHIPPED HIM TO DAG. DAG DID NOT CLB ACFT. I HAD A TWIN VFR OFF HND. I IDENTED HIM AND CLRED HIM THROUGH CLASS B AIRSPACE; TOLD HIM TO MAINTAIN AT OR BELOW 7000 FT. I DID NOT REALIZE C421 HAD NOT BEEN ISSUED A CLB. THE CONFLICT ALERT WENT OFF AND I WAS NOT RECEIVING MODE C FROM THE TWIN. I ASKED THE TWIN HIS ALT. HE SAID 6600 FT. I TOLD HIM TO MAINTAIN THAT AND THERE WILL BE AN E120 PASSING OVERHEAD. PRIOR TO THIS INSTANCE; I WAS EXTREMELY BUSY ON THIS POS AND WAS GOING ON MY FIFTH HR ON POS FOR THE DAY. FOR THE AMOUNT OF TFC WORKED THAT DAY (ON SUNDAYS) THAT IS A LONG TIME TO BE ON POS AND HAD I NOT HAD THAT ERROR; I WOULD HAVE WORKED 6 HRS. I BELIEVE FATIGUE PLAYED A FACTOR IN THIS ERROR. TOO MUCH TFC; BAD PROCS AT THE FACILITY; AND GROSS UNDERSTAFFING WILL CONTINUE TO LEAD TO ERRORS AT L30.
