I believe you're quite wrong. I read the article. They discovered some minor non-conformance that's not safety related and are fixing it. Airplanes are incredibly complex machines with millions of parts. Scaling this analogy it's like a finding a minor manufacturing issue with the iPhone's PCB. Which probably happens all the time and you'd never know or hear about it. I can't think of a single Apple product I've owned that didn't have some defect that required a widespread "repair program" to resolve.
