The deal is it just doesn't happen very often. The parts are traceable
right back to the manufacture down to every sub that performed an
operation. If someone sold a faulty part they would get caught. When an
aerospace company buys parts all certs are required.
Not true at all - you might want to check into what the ASA says about
this. You might also want to check into what the FAA says about
"building" spare parts.

You seem to be confusing serviceability with traceability. The fact is,
anyone can buy and sell anything without paperwork as long as they do not
represent it at serviceable material. Industry standard does require
trace to the last regulated source that owned the part, but there is no
law saying it must be provided.

Then an AP would have to install the part or a FAA approved station. Again
what AP or FAA approved work station would install this part. This is what
insures the part was built to spec. Again part is traceable.

In addition, industry standard certainly does not require trace to the
manufacturer for most aircraft parts.
Your wrong. Show me one part not traceable.
The exceptions are life limited
engine parts, which ARE generally required to be traced to the
manufacturer. Maintenance documents for the life of the part are also not
required, even for the above mentioned life limited parts.
The amount of years has changed different companies require different
lengths of time.

Disclaimer - The above refers to commercial industry standards, not FAA
requirements or GA spare parts.
