The accident rate for GA aircraft is similar, or even slightly better in the US over the UK. This is done with a much more practical pilot licensing regime and aircraft maintenance requirements. The ridiculous level of over the top regulatory requirements in the UK has done nothing but force UK based aircraft onto the N register.

I would suggest you should be careful with what you wish for as you may get it. Getting rid of UK based N registered aircraft will reduce the already low level of UK GA hours to a level that may make many parts of the UK GA infrastructure unsustainable
