They now come as standard from the factory
An aircraft manufacturer can certify “anything” under their TC. Examples.
Whether that can be used in Europe to certify a Major mod, I don’t know. I know that in the FAA system you can use it, in specific ways.
It is also possible that, post-brexit, the UK CAA is more flexible on approvals based on US approvals. They might directly accept US STCs for example – even if they do it under the table to avoid p1ssing off EASA and compromising future CAA-EASA agreements. It would make sense, but a) I have not heard of this and b) always be ultra wary of “we are working on certification” statements which this business is full of and mostly they are BS, for years, or worse.
The EI business has a particularly bad history of pushing products out, and so far AFAIK nobody has managed to certify a standalone magneto replacement.
EDIT
On the topic of cost saving, read the ICA. Almost nobody does. The Surefly has a 2400hr life limit.
I thought it must have because it rotates so there must be something… Like the B&C alternator has a 1700 HR limit.
Compliance is return to factory, in the US.

It’s a recommended interval for replacement OR factory inspection, but not an airworthiness limitation. Their airworthiness limitation section explicitly says “none”.
Right – thanks for pointing that out.
I checked the B&C 410 backup alternator IM also – the 1700 hrs is a “recommendation”.
However, we don’t know what text will be in the EASA (or UK CAA – is this really real??) STC, if/when it arrives. EASA tends to be more prescriptive on this stuff.
@bathman – referring to that (unknown type) plane which you say comes with the Surefly mags, assuming it is G- or EASA-reg, what is the text of the AFMS on the magnetos?
