It isn’t relevant - the final assembler is responsible for QC.

If I build something, and I buy something from a third party to be part of it, I make sure that

A) it isn’t defective B) it integrates robustly

You can wave your hand at the supply chain all you want, but if you’re sticking your name on it, it’s yours.

The plane was built in 2015.

This is not about building the engine doors, it's about who did not close them properly during last maintenance.

My laptop breaks down after 5 years.

Is it about the manufacturer because they made a bad design that broke after some years, or me doing properly maintenance?

I’m afraid you’ll need to contact shenzen resistor corporation #6552 as that’s the component that’s failed and they’re the responsible party.

Is this a brand new airplane or caused by some design flaw? Because if not everyone should probably be blaming the airline/maintenance company.

Certainly not downplaying Boeing’s massive screwups but it just seems that every single incident that everyone just used ignore in past is now an international news story (but only if a Boeing plane is involved)

Neither. It’s an error by whoever last did maintenance on the engine and didn’t latch the door properly, and the pilot doing the walk around missing that error. Not a Boeing issue whatsoever.

Except e.g. a bolt broke. And the bolt was either build by the engine manufacturer, by Boeing or installed during maintenance by the airline (or outsourcer).

You can wave your hand at the supply chain all you want, but if you’re sticking your name on it, it’s yours.

Definitely not true for airplane engines.
