This is a bad take. “Real” parts are known. Real parts are tested, and their failure modes are understood in relation to each other. Yea you can get lucky on a fake or a bad apple on a real one but that’s just luck. The story surely would be “delta accidentally has been buying a superior part” if the parts were more reliable.
> As to "fake" parts, we don't know the whole situation yet; they may be genuine parts but just may lack certification
If this was the case it wouldn’t have forged certification. The only way this would be true is if delta was buying genuine parts from sketchy resellers and distributors which doesn’t make them look much better.
The damning evidence to all this is the forgery. If you buy “off brand” generic parts, you should know that you are. To forge a document is a deliberate, non accidental, action to lie and deceive. Why would anyone do that unless the part was inferior?

To save certification costs. For many safety critical parts, the actual manufacturing is a small part of the cost - the testing / certification process is the bulk of it.
(This is no excuse, natch - the part may or may not be inferior, but without the process we have no way to know; and for safety critical applications WE NEED TO KNOW.)
That isn’t any better. Mechanical parts have finite lifetimes for a reason. If a part is known to develop stress fractures after 5000 hours, it may have be required to replace that part after 3000 hours, even if there are no visible signs of wear at that point. If that part is then re-sold as new with a forged history, that’s a problem.
That is inferior to new, considering physical goods have a limited mechanical lifespan.
Either way, it misses the point that the product is a lie sold on false pretenses. Lying about what you sell is not a good sign. There is no world, no product conditions, no anything, where a lie about what’s being sold should be tolerated. Fraud a crime for a reason.
> We just don’t know at this point.
At this point I already know I’d pick the plane with genuine certified parts if I had the choice.
> and their failure modes are understood in relation to each other.
This is super important and why the other poster really doesn't know what they're talking about.
These things are most definitely tracked, anyone who thinks otherwise is encouraged to do a search for MTBF, MTTR, etc. Even the most simple manufacturing plant will track these and do things like keep parts on hand or not based upon them.
