Narrative:

Air carrier X departed pit runway 28L with an initial heading of 200 degree and climb to 5000'. Air carrier Y was descending to land pit runway 32 from the southwest turning to 090 degree and cleared to an altitude of 2500'. Air carrier X would pass behind air carrier Y, but as the aircraft emerged from over the 'main bang' antenna and 'tagged-up' with the ARTS, it surprised the arrival controller who was working air carrier Y and he asked me to turn air carrier X wbound. I turned air carrier X and amended his altitude to 4000'. He acknowledged the turn and advised that he was through 4500' and would descend back to 4000'. The arrival controller stopped air carrier Y at 5000'. Supplemental information from acn 124707: action was taken to separate the aircraft but standard separation was not maintained.

Original NASA ASRS Text

Title: A DEPARTING ACR CONFLICTED WITH AN ARR ACR RESULTING IN LESS THAN STANDARD SEPARATION.

Narrative: ACR X DEPARTED PIT RWY 28L WITH AN INITIAL HDG OF 200 DEG AND CLIMB TO 5000'. ACR Y WAS DESCENDING TO LAND PIT RWY 32 FROM THE SW TURNING TO 090 DEG AND CLRED TO AN ALT OF 2500'. ACR X WOULD PASS BEHIND ACR Y, BUT AS THE ACFT EMERGED FROM OVER THE 'MAIN BANG' ANTENNA AND 'TAGGED-UP' WITH THE ARTS, IT SURPRISED THE ARR CTLR WHO WAS WORKING ACR Y AND HE ASKED ME TO TURN ACR X WBOUND. I TURNED ACR X AND AMENDED HIS ALT TO 4000'. HE ACKNOWLEDGED THE TURN AND ADVISED THAT HE WAS THROUGH 4500' AND WOULD DSND BACK TO 4000'. THE ARR CTLR STOPPED ACR Y AT 5000'. SUPPLEMENTAL INFORMATION FROM ACN 124707: ACTION WAS TAKEN TO SEPARATE THE ACFT BUT STANDARD SEPARATION WAS NOT MAINTAINED.
