Narrative:

I was informed by management that aircraft r-hand overwing slide and compartment door were missing on arrival at ZZZ in may/xb/07. Aircraft was in ZZZ1 for b-chk may/xa/07. I was accomplishing work card; rearming of left and right overwing slides. After accomplishing rearming procedures of l-hand overwing slide; I proceeded to the r-hand overwing slide. I repositioned the disarm lever to the armed position while holding down the switches; and verified the switches were in the down position as per work card. While connecting the cannon plug to the battery pack I heard the squibs fire. I then deactivated the right overwing slide system. I initiated maintenance write-ups for 2 each door open actuators; door latch actuator and spoiler override actuator. After which I changed the 2 door open actuators and the spoiler override actuator. I reconnected the cannon plug to the spoiler override actuator and performed the squib test; which failed. I found the squib discharged on the new spoiler actuator. I verified the r-hand overwing slide system was deactivated. Then I aog'd the parts required: the status of the aircraft was given to next shift. Supplemental information from acn 741199: may/xa/07; during routine post check close up; a step was incorrectly accomplished and rw off wing door slide actuator discharged. I arrived to work an hour prior to new rw off wing door actuator being installed. I witnessed actuator/door installation -- all performed normal.
