I'm afraid that hoping for any level of rationality in these sort of rules is likely to be invain. The CAA have had a mindset of gold plating everything for a very long time. With their income stream now threatened by EASA they are even less likely to think sensibly and help create a rational risk based approach. EASA presently has some proposals which at the moment look promising but you only have to look at the CAA's insistance that they must inspect already certified EASA aircraft before they can go on the CAa register to see their real motivation.....
