Re: Brexit?
The UK can keep on copying EASA regulations, in the same way that EASA and FAA certification schemes are, in most cases, paragraph by paragraph identical. However, unless the CAA can get the manpower to perform all the required audits and inspections, aircraft parts produced in the UK WILL NOT BE AIRWORTHY. This goes for wings, for jet engines, for avionics etc. etc. Pilots and airliners get a lot of attention because the UK populace will notice it if the UK airliners are not allowed to fly them in and out of the country, but the main problem (IMHO) will be the manufacturing industry. Since this will also hurt the non-UK aviation industry, the problem WILL get attention at some point, but not without a lot of hurting.
The brexiteers can be proud of their Spitfires (complete with polish pilots), they are about to kill of the industry that created them.
