As I wrote elsewhere, under EASA rules high ranking people at an organization holding design and / or production organisation approvals, are personally responsible, and liable incl. criminal liability, to make sure their organisation works properly. I forget the exact term for this role so.

Not sure about FAA rules, but I assume they are somewhat similar. So at the very least, those individuals, at Boeing and Spirit Aerospace, should be a tad worried now. By the way, senior means VP-levek and above, usually one for the design side (propably less relevant in the door plug question), one on production side (they should be worried), one each for design and production quality (same as above, the production quality oeople should be worried a lot) as well as one for supply chain and other functiobs with less responsibilities (the supply chain people are imolicated in this door plug thing as).

Personally, I don't see how the FAA can just let this slip, their relationship with international partbers and their reputation is already damaged by the 737 MAX, so they have to do something about it.
