> Unfortunately, there is nothing Delta and other Airlines could have done to prevent this from happening. You posit that the necessary information was not available to Delta, at least not immediately, due to outsourced engine maintenance. Why can't Delta require their contractor (which wasn't the supplier, AOG) to check that documentation meets requirements? Why can't Delta check the documentation themselves once it is available, prior to the engines needing later service as in this case? |

It was not a problem of absent documentation, because that is obviously rigorously checked by everyone in the chain. So Delta, and regulators, force suppliers to check all documentation for parts. Delta doesn't have to check their sub-tier suppliers documentation, since their tier one is a certified company (in Europe that would ne EASA Chapter 145 for maintenance). What Delta does, is auditing their tier 1s, those tier 1s audit their tier 1s (Delta's sub tier suppliers), and ao on and ao forth.
AOG was audited and certified, which means their paper wirk, process discriptions and so on were compliant. And then AOG cheated, kind of like showing good parts for audit and supplying crap later. If AOG, or anyone else, is that criminal, the only way to catch them is by chance or an investigation after a part fails.
