there was apparently two (identical) procedures -- one for "removing" the door plug and one for "opening" the door plug -- but only one of them actually called for paper-work and quality inspection after it is done.
It seems they decided to "open" the door plug instead of "remove" it to work on the sealing issue? -- and thereefore documentary record of the work performed and inspection thereafter is lacking.
It would be useful IMO to explore what led the team to prefer "opening" versus "removing" -- and if the subtle difference in documentation requirement was a consideration in preferring one over the other -- and if that points to deeper pervasive culture issues that leans towards less work rather than give safety and quality the primary importance.
