Narrative:

Replacement of dual FMGC's. Performed afs test for FMGC #1; #2 and functional aircraft check #1; #2. All checks passed. Performed land test function check (land and capability check). All function checks passed. Lead mechanic and myself viewed test results. Contacted maintenance operations center with results and asked if any open CAT items existed. Was advised none were noted; cleared FMGC write-ups and CAT was upgraded to CAT ii; III; III dual operations. All items recorded in aircraft logbook. Arrived work on apr/thu/06. Was advised by other personnel that an open item (CAT) was not addressed with aircraft. A CAT entry for functional aircraft check #1 and #2 had not been closed and remained open. This item was not observed. For this reason; a logbook entry stating a functional check of functional aircraft checks #1 and #2 was not entered. Although a functional check of the functional aircraft checks had been performed when the FMGC's were replaced. It is my firm belief that I had followed proper procedures; and advised the proper personnel; and had completed all paperwork to the best of my knowledge and abilities.
