Narrative:

Recently it has been brought to my attention a problem which arose with aircraft X on oct/tue/01/. On the above date the spoiler miter was due for a time change. At that time was discovered that r-hand wing cables WSA1-2 and WSA2-2 (spoiler control) were wrapped around each other. The problem was rectified on that date. On may/thu/01, I originated discrepancies for spoiler control cables WSB2-1 corroded nr (non-routine write-up) B235193, WSA1-4 corrode nr B235189, WSB1-4 corroded nr B235191, WSA2-4 corroded nr B235190, WSB2-4 corroded nr B235192. I inspected the fabrication and partial installation of all the cables. Due to shift change I referenced the system rig, safety wiring of the turn-barrels after connection on nr B235435 which was accomplished by a different inspector/mechanic that day. The cables found crossed on oct/tue/01 were not written-up by me for corrosion, but were connected downstream in the spoiler control system. When I turned over the job on may/thu/01, none of the cables tensioned up and the turn-barrels were loose and might have been disconnected again during the rigging process later in the day. No damage to the cables or aircraft structure was found on oct/tue/01.
