Narrative:

I was working D16 combined with R16. Fgt X was at 12000 direct nlc from R2508 complex. Small transport Y was at 11000 fat direct ehf. I had the 5 mi ring upon small transport Y. I had switched fgt X to nlc approach. I was busy. I climbed small transport Y after fgt X had passed, but realized when small transport Y was passing through 12000 that even though aircraft was clear I didn't have 5 mi. It was about 4 increasing. I turned small transport Y 30 degree left and pilot said he had traffic in sight. In reflection, I forgot about fgt X and climbed small transport Y I knew they were past each other, but was inattentive to the required 5 mi. It was busy and another pair of eyes may have helped prevent this situation.

Title: ACR SMT CLBED THROUGH FGT ALT WITH LTSS.

Narrative: I WAS WORKING D16 COMBINED WITH R16. FGT X WAS AT 12000 DIRECT NLC FROM R2508 COMPLEX. SMT Y WAS AT 11000 FAT DIRECT EHF. I HAD THE 5 MI RING UPON SMT Y. I HAD SWITCHED FGT X TO NLC APCH. I WAS BUSY. I CLBED SMT Y AFTER FGT X HAD PASSED, BUT REALIZED WHEN SMT Y WAS PASSING THROUGH 12000 THAT EVEN THOUGH ACFT WAS CLR I DIDN'T HAVE 5 MI. IT WAS ABOUT 4 INCREASING. I TURNED SMT Y 30 DEG L AND PLT SAID HE HAD TFC IN SIGHT. IN REFLECTION, I FORGOT ABOUT FGT X AND CLBED SMT Y I KNEW THEY WERE PAST EACH OTHER, BUT WAS INATTENTIVE TO THE REQUIRED 5 MI. IT WAS BUSY AND ANOTHER PAIR OF EYES MAY HAVE HELPED PREVENT THIS SITUATION.
