Boeing is having a rough time of it right now, with parts falling off its planes left, right and center. Just last week, a wheel came loose and smashed through a car, and earlier this year the door from a 737 Max aircraft broke off mid-flight. That mid-air disaster sparked an audit from the Federal Aviation Administration, which has gone far from well.
Oh my god, no they’re not. The vast majority of the issues being reported on right now are maintenance issues that are the responsibility of the airline.
Boeing needs to get its shit together but 33 QA failures is pretty damn small in the literal thousands of QA checks that go into the production of every aircraft. Flying is still the safest means of travel, even on a Boeing aircraft.
