This is a sign that there are extremely right safety standards and lots of oversight. The amount of documentation needed for all aerospace parts means it is quite difficult to falsify records for long without getting caught. The fact that any of these types of event are big news and often result in arrests should help you be confident that the standards are real and enforced. There will always be bad actors, and finding them like this is part of reality. Just look at the safety record of commercial aviation to see proof that the system is working.
