FAA unapproved parts notifications, searchable and matched to every listing

When the FAA finds parts produced or sold for certificated aircraft without approval, it publishes a notice naming the producer and the parts. Those notices live on the FAA site as yearly tables and PDFs. We pulled all 213 of them into one searchable list at /unapproved-parts, with the part numbers parsed out of the notice text.

The useful part is the matching. Every part number listed here and every vendor's business name is checked against the list. A match shows on the part page, in the FAA tab, and on the vendor page. No match shows too: a vendor page now carries the line "No unapproved-parts notification names this company", which is the trust signal a buyer actually wants.

The list refreshes daily. Read the notice itself before acting on a match: a part number can be legitimate from an approved source and unapproved from another.
