Statistically, there is no difference between a new plane and one that's been flying for 18 years [1].
Given dying because an installer fucked up feels mighty similar to dying because a maintenance tech fucked up, I don't see a rational reason to over-penalise fabrication errors to the extent that it overrules millions of successful flight miles. (Design mistakes are categorially different.)
