The paperwork cost isn’t negligible at all. For example a company I used to work for had to replace a simple O-ring that failed. It’s an old part and quite rare these days and cost $800 to replace. You could buy a functionally equivalent (likely better) uncertified part for about 5 cents. That is why uncertified parts are such a problem, because certified ones are so incredibly expensive. Plenty of companies would love to step in and buy a few thousand O rings and sell them for $400 and a few are willing to forge a paper trail to make it happen. It’s a problem that I don’t really think will be ever totally solved without making certification too easy and potentially sacrificing safety by having bad certified parts.
If you spent $800 on an oring and it fails and the plane goes down, the manufacturer is liable. If you spent $0.05 on the oring and the plane goes down, you’re liable. Like you said, paperwork isn’t cheap. Because its basically liability insurance. If you made the oring, would you accept liability for $0.05?
