It's quite absurd to me that the manufacturing of planes by Boeing has less stringent QC done by themselves on their main components provided by vendors than many consumer electronics do for their suppliers. How could Boeing not have their own QC personnel checking the work done by a supplier of bodywork? Of course I believe it's down to cost-cutting, while also shifting the liability unto their vendor in case something is out of spec. Vendors who signed a contract with probably many clauses specifying they are on the line instead of Boeing in case of missed specs on their parts. Still, it's the main bodywork of their planes, how are they not "trusting but verifying" this all the way through? What a fucking rotten corporate culture, the best it could happen to this company is to be nationalised, let the government purge the current directors and try to install competent people to recover. I don't think there's any other way for Boeing to change its corporate culture after so many decades of rotting without an internal revolution.

> It's quite absurd to me that the manufacturing of planes by Boeing has less stringent QC done by themselves on their main components provided by vendors than many consumer electronics do for their suppliers. That's quite a claim. A single modern airliner is 300,000-500,000 parts (depending on the model) that have to be manually inspected by multiple people compared to a tiny IC that can be automatically tested by a machine or a PCB that can be electrical tested with automated probes. From TFA: > Boeing requires fastener holes in this section of the plane to be drilled at .2475 inches, which provides a near-perfect “interference-fit” that best retains air pressure during flight. Instead of drilling at that size, Spirit workers were directed to drill holes using a .2495 drill bit, to clear excess paint from the holes and speed up a slow process. Oh and by the way, each hole has to be checked to within _2 thousandths_ of an inch.... They're not even remotely comparable. An ASML UEV lithography machine is on the order of a 100,000 parts so that'd be like Intel and TSMC taking apart and running a precision CMM over every part on their main machines thousands of times a year (during which Boeing ships and inspects about 500 new planes).

I was very specific on mentioning bodywork of the aircraft as a critical main component that they shouldn't left suppliers do their own QC, not all the 300-500k parts...
