Then no airplane will fly. Every one of them has a risk of catastrophic failure and only flies because the likelihood of such failures is low.
The whole point of safety processes is to identify, quantify and mitigate the inherent risks.
No airplane will ever be risk free. All we can do is mitigate them to an acceptable level.
And what's acceptable is constantly changing, with an ever more risk averse society. What was an acceptable risk in the 80's isn't today.
