Narrative:
I received an escape slide which was removed from aircraft aft service position for time change. I noticed that the latch assembly had been removed and a new latch with new hardware was loose in the shipping box. The slide which replaced this one was in our shop earlier and received the cco (engineering change order, modification) with new hardware. It was found through follow up that when the slides were swapped out, our new hardware was removed from the serviceable slide and old hardware was installed on the serviceable slide. This left our slide with old parts and cco now circumvented, yet records will still show me as the one responsible for the airworthiness directive cco being complied with.
