what the Spirit mechanics had to do was a RMV, they knew this, because the Boeing eng rep told them so, but they didn’t like this, so they marked it in the system as an OPEN but performed the work of a RMV, to avoid the additional quality checks a RMV would require. And then they fucked up the RMV but didn’t know and no one else did because it was marked as an OPEN so no one checked the bolts.

this was very intentional. the Spirit mechanics thought they were hot shit and didn’t need to follow the stupid, slow process. and they abused the system to allow them to file the work as more innocuous than it was. because they didn’t need anyone checking their work, or whatever they were thinking.
