I’m not expert enough to know if this is dangerous are not. But an aircraft is a combinatorial explosion of complexity. For example, innocuous sounding changes for the 737 Max caused several hundred deaths. If the tolerance was indeed too strict I would expect Boeing to go through a engineering review and seek approval from the FAA. People who work on assembly lines are really good at keeping the line moving. But I don’t want someone who’s perf bonus relies on pushing out aircraft determining on-the-fly if something that’s outside of the spec is safe or not… And this isn’t a knock on blue collar labor, almost no one at Boeing has the knowledge to work through all the potential side effects like this.
