Not a specialist but with CS-STAN you have a form to fill, send a copy to EASA and keep a copy in the a/c maintenance record. Depending the change/repair, the pilot-owner or an engineer can sign the release to service.
You don’t send any forms to EASA or your NAA. Th engineer signs the Form 123, as does the aircraft owner to accept the modification and that’s it.

Well, the italic passage above will basically stop me from radiating ADS-B out with my GTX330ES. I don’t need to upgrade my GNS430s to WAAS or GTN / IFD models. The only solution would be a special GPS source north of 4k installed, including paperwork.
How come? CS-STAN describes standard installations/repairs you can do without an STC or EASA approval. If you already have an ADS-B installation approved via an STC or directly by EASA, then that approval with still be valid. If you don’t, the change to CS-STAN won’t make it any more illegal than it already is – possibly less. :-)

Presumably the italic passage is a, ahem, hmmm, you know…. “friendly” way of saying the interconnection has to appear in the transponder Installation ManualObviously.
The IM is approved by the certification authority so putting an interconnection in the IM is an implicit installation approval.
That depends on the wording. The Trig TT31 mentions five GPSes/GPS families, including GNSxxxW and GTN, but it also states: “At the time of publishing this manual, enabling the ADS-B Out feature is considered a major change and will generally involve further approval”, so you can’t take it as an implicit approval.

Because Garmin will not allow any GPS source to be connected to their GTX 330 and confirm it works except one which costs north of 4K installed. The wording there means that the equipment manufacturer has to confirm that the GPS source will work with the transponder. In my case, the 430s non WAAS are not accurate enough to allow ADS-B out, the only options would be something like a GTN650, IFD440, 430w upgrade or fitting of an approved source. Approved by Garmin.

It means that if you want to make an ADS-B installation without a STC or change approval from EASA, then the manufacturer indeed has to confirm. But right now, you can’t make an ADS-B installation at all without a STC or change approval. So it might be that the revision to CS-STAN is not helpful in your case, but it doesn’t make anything worse.
You are not forced to do things according to CS-STAN. It gives opportunities to make some things easier.
It is worth noting that this CS-STAN only applies to SIL-0, not “proper” ASB-out installations

There are two proposed new CS-STANs for ADS-B installations, CS-SC005a and CS-SC006a. The one I described is CS-SC005a which allows for a “proper” ADS-B installation. The other one, CS-SC006a, concerns ADS-B installations for the purpose of “airborne awarness” in GA aircraft. It doesn’t require the manufacturer statement of compatibility, but it also only allows SIL-1 (not SIL-0).
Ah, I see – thanks!
This just turned up on email:
Please note that the final deliverable ‘Regular update of the certification specifications for standard changes & standard repairs (CS-STAN) – Issue 3’, as well as the related CRD to NPA 2018-10 , have been published on the EASA website.
CS-STAN issue 3 has come out. Local copy. May be 1 year old news…
