In 2013, they externalized the construction of the metal rings that make the body. It was supposed to be CNC’d, but the provider obviously made them manually, with all the mistakes that entails, including sloppy sawing and cutting holes in the wrong places. It was validated for production, because of political pressure to not blame the provider. Boeing re-cut the holes in the right places, making them twice weaker. So yes, the MAX isn’t the first unsafe plane of Boeing. That it wasn’t proven that it caused accidents, doesn’t mean it was safe. And there are countless other affairs like this. The lithium batteries.
