FAA STCs
Yes that's pretty much the may it works. All of the JP Instruments systems - EDM760, FS450 etc are installed under this route.
In the past, the person who owned the AAN (the original applicant who paid the fee) gave permission for someone else to use the AAN, in a similar way to the method the FAA currently dictate. This is where the FAA STC holder must give written permission for someone to embody the modification. In reality, if you find the validated FAA STC in EASA, CAA or LBA lists you can pretty much just get on with it, provided you have the full STC data package.
The one area which can catch people out is if the AAN or other validation calls up any limitations or a particular AFM supplement which may vary from the original FAA document. It's important, therefore, to obtain not just the AAN approval number, but also the actual AAN document so you can check on limitations and applicability.
