I’m sure the process exists. But I can understand how an employee could mess it up. If some fairly common work on an airplane involves opening a door, I imagine it’s okay to open and close the door without documenting it. (Just like (I imagine) turning on and off some lights or locking and unlocking a door, etc.) But now there’s a special kind of door (that’s really a plug but works a bit like a door and is literally called a “door plug”), and opening it involves removing four bolts but does not involve removing it completely from the fuselage. So, in a culture where there isn’t a checklist that gets followed for everything, they think “I opened the door (plug)” instead of “I partially removed the door (plug)”, and then they access the rivets (and document that!), and then they sloppily “close the door (plug)” and it is indeed “closed”. But they might not be thinking “I reinstalled the door (plug),” and they don’t check the checklist or fill out the form, and no one ever tracked those four bolts, and a near-catastrophe occurs.

So one might argue that calling this thing a door (plug) and “opening” it is a mistake. And one might argue that a design that “closes” a bit like a door but isn’t correctly installed when it looks closed is a poor design.
