Narrative:

I was working the arrival east sector at clt TRACON. I was working small aircraft X at 4000' inbound to a satellite airport in clt airspace. I pointed small aircraft X out to departure sector since small aircraft X would transit through 14 NM of departure's airspace. Departure was working air carrier Y eastbound. I noticed the mode C readout of 3400-3500 and queried the departure controller. Departure controller informed me that he forgot about small aircraft X. We both took evasive action. Small aircraft X saw the air carrier Y. I then instructed small aircraft X to maintain visual separation and cleared the aircraft on course. The aircraft missed each other by approximately 1 NM. The departure controller was busy at the time. He should have had an assistant helping him. But we don't have enough controllers. I first considered handing off small aircraft X to departure but elected to keep the aircraft to ease his workload.

Title: SMA CAME IN CLOSE PROX TO AN ACR BEING WORKED BY ANOTHER CTLR.

Narrative: I WAS WORKING THE ARR E SECTOR AT CLT TRACON. I WAS WORKING SMA X AT 4000' INBND TO A SATELLITE ARPT IN CLT AIRSPACE. I POINTED SMA X OUT TO DEP SECTOR SINCE SMA X WOULD TRANSIT THROUGH 14 NM OF DEP'S AIRSPACE. DEP WAS WORKING ACR Y EBND. I NOTICED THE MODE C READOUT OF 3400-3500 AND QUERIED THE DEP CTLR. DEP CTLR INFORMED ME THAT HE FORGOT ABOUT SMA X. WE BOTH TOOK EVASIVE ACTION. SMA X SAW THE ACR Y. I THEN INSTRUCTED SMA X TO MAINTAIN VISUAL SEPARATION AND CLRED THE ACFT ON COURSE. THE ACFT MISSED EACH OTHER BY APPROX 1 NM. THE DEP CTLR WAS BUSY AT THE TIME. HE SHOULD HAVE HAD AN ASSISTANT HELPING HIM. BUT WE DON'T HAVE ENOUGH CTLRS. I FIRST CONSIDERED HANDING OFF SMA X TO DEP BUT ELECTED TO KEEP THE ACFT TO EASE HIS WORKLOAD.
