I'd certainly be totally in favour, as I've posted elsewhere, in the UK adopting the FAA's DAR system at the very least.
As I'm an airworthiness engineer, amongst other thing, I went and had a look at the adverts, which are here:-
https://careers.caa.co.uk/job/Gatwick-D ... 630724501/
The adverts are very poorly constructed, don't list salaries, but in general terms the skillset they're after is extremely rare. Could I do it? Yes. Could they afford me? probably - CAA have always paid very well for the skillsets. Do I have any desire to work in the Belgrano? Not on your Nelly. Do I know many people likely to be job hunting who have the skillset? Very very few indeed.
I really hope they're advertising in the USA, it's probably the only place they've a lot of chance of getting significant numbers of people with these skills. Their own systematic and deliberate de-skilling over the last decade has done the UK no favours whatsoever.
