> The problem is that we don't know which other parts and systems Boeing might have quality issues for. We don't need to go through everything, at least not immediately. We know the door/bolts have issues, so we can just scrutinise those really carefully. The crucial part is not looking at whether there are issues (we already know there are), but at the nature of those issues. Are they localised and contained, or are they systemic? The extent to which they're systemic tells us how worried we need to be about everything else in the planes (Personally, given the MCAS situation, I don't believe for a moment these issues are not systemic, but a layperson's semi-educated guess isn't a valid basis for an airplane audit)
