Narrative:

During troubleshooting of 'spoiler' EICAS message, #13 spoiler PCU was replaced per maintenance manual. (Ship xyz.) this occurred oct/mon/99, around XA00-XD00. The plane was subsequently released and flew without incident. Later oct/tue/99 afternoon it was brought to my attention that the list of rii (required inspection items) had changed last apr/xa/99, in our topp (technical operations policy and procedure manual), and where no rii was required previously for replacement in a line maintenance situation, it now was required. Upon discovery of our omission, I set up to have the inspection performed by quality assurance during its next transit to ZZZ, oct/wed/99. The inspection was performed and documented in aircraft logbook. I also initiated a maintenance advisory to bring heightened awareness to the rii change. Normally changes to topps are a 'read and sign,' so all are aware of the change. In my case, I had been involved with the B777 program, had no 'read and signs' for about the last yr, and was unaware of the change. A contributing factor would be no inspection or rii called for in maintenance manual.

Narrative: DURING TROUBLESHOOTING OF 'SPOILER' EICAS MESSAGE, #13 SPOILER PCU WAS REPLACED PER MAINT MANUAL. (SHIP XYZ.) THIS OCCURRED OCT/MON/99, AROUND XA00-XD00. THE PLANE WAS SUBSEQUENTLY RELEASED AND FLEW WITHOUT INCIDENT. LATER OCT/TUE/99 AFTERNOON IT WAS BROUGHT TO MY ATTN THAT THE LIST OF RII (REQUIRED INSPECTION ITEMS) HAD CHANGED LAST APR/XA/99, IN OUR TOPP (TECHNICAL OPS POLICY AND PROC MANUAL), AND WHERE NO RII WAS REQUIRED PREVIOUSLY FOR REPLACEMENT IN A LINE MAINT SIT, IT NOW WAS REQUIRED. UPON DISCOVERY OF OUR OMISSION, I SET UP TO HAVE THE INSPECTION PERFORMED BY QUALITY ASSURANCE DURING ITS NEXT TRANSIT TO ZZZ, OCT/WED/99. THE INSPECTION WAS PERFORMED AND DOCUMENTED IN ACFT LOGBOOK. I ALSO INITIATED A MAINT ADVISORY TO BRING HEIGHTENED AWARENESS TO THE RII CHANGE. NORMALLY CHANGES TO TOPPS ARE A 'READ AND SIGN,' SO ALL ARE AWARE OF THE CHANGE. IN MY CASE, I HAD BEEN INVOLVED WITH THE B777 PROGRAM, HAD NO 'READ AND SIGNS' FOR ABOUT THE LAST YR, AND WAS UNAWARE OF THE CHANGE. A CONTRIBUTING FACTOR WOULD BE NO INSPECTION OR RII CALLED FOR IN MAINT MANUAL.
