Narrative:

I was working drn at pit. Air carrier X departure off pit called in and I climbed him to 13000'. The arn controller called to me to watch air carrier X, and I then saw air carrier Y and issued a stop climb to air carrier X and also issued the traffic to him. He reported the traffic in sight. I issued maintain visibility sep. Contributing factors: I was not aware of the fact that arn was vectoring aircraft from the southwest over the airport for right traffic for runway 28R. Air carrier Y was originally tagged for 28L. At the time of the error I was distracted by an aircraft calling for clearance to enter the TCA, and I was entering the aircraft identify in the ARTS and writing the flight data strip. Supplemental information from acn 177243: I was working feeder north in the pit TRACON when I observed air carrier X under the control of departure north entering my airspace, resulting in a loss of sep with air carrier Y. I called the traffic to air carrier Y, asking if he had the other aircraft in sight, and took evasive action by issuing an immediate climb to 7000' MSL.

Original NASA ASRS Text

Title: ACR X ERRONEOUS PENETRATION OF AIRSPACE HAD LESS THAN STANDARD SEPARATION WITH ACR Y. SYSTEM ERROR.

Narrative: I WAS WORKING DRN AT PIT. ACR X DEP OFF PIT CALLED IN AND I CLBED HIM TO 13000'. THE ARN CTLR CALLED TO ME TO WATCH ACR X, AND I THEN SAW ACR Y AND ISSUED A STOP CLB TO ACR X AND ALSO ISSUED THE TFC TO HIM. HE RPTED THE TFC IN SIGHT. I ISSUED MAINTAIN VIS SEP. CONTRIBUTING FACTORS: I WAS NOT AWARE OF THE FACT THAT ARN WAS VECTORING ACFT FROM THE SW OVER THE ARPT FOR RIGHT TFC FOR RWY 28R. ACR Y WAS ORIGINALLY TAGGED FOR 28L. AT THE TIME OF THE ERROR I WAS DISTRACTED BY AN ACFT CALLING FOR CLRNC TO ENTER THE TCA, AND I WAS ENTERING THE ACFT IDENT IN THE ARTS AND WRITING THE FLT DATA STRIP. SUPPLEMENTAL INFO FROM ACN 177243: I WAS WORKING FEEDER N IN THE PIT TRACON WHEN I OBSERVED ACR X UNDER THE CTL OF DEP N ENTERING MY AIRSPACE, RESULTING IN A LOSS OF SEP WITH ACR Y. I CALLED THE TFC TO ACR Y, ASKING IF HE HAD THE OTHER ACFT IN SIGHT, AND TOOK EVASIVE ACTION BY ISSUING AN IMMEDIATE CLB TO 7000' MSL.
