Narrative:

Flight xyz aircraft a arrived at XB56Z. I proceeded with the outside arrival inspection, and my partner handled the cockpit check and met the crew. After I finished the exterior check, I informed my partner that the outside was good. Flight yyz aircraft B arrived at XB06. I started the cockpit check and the initial walkaround. This plane was to remain all day. My partner was doing the engine inspection and oil service. I finished the initial arrival inspection on aircraft B and when I brought aircraft B's logbook to the truck, I saw the logbook from aircraft a. (It is an outbound and normally the logbook would remain onboard.) I saw there was a write-up on #1 reverser. I went and got my tools and proceeded to deactivate #2 reverser. My partner had brought both logbooks to the office. I was very careful to get everything right since I heard some horror stories about deactivating the airbus reverser. Per MEL mxp 78-1, made sure I had all plugs capped and secured and lock plates were turned on the CDU's auxiliary drive pads. The red deactivation plates were installed and engine/reverser control breaker was reset, closed the cowl, confirmed that the throttle control lever had full travel. Rechked cowl, went to the office. My partner was entering the item in the computer. The captain came while this was going on. None of us caught the mistake.
