Re: Well, that's it then
Indeed, but unfortunately the UK CAA (as part of the post brexit rush to distance from anything European) has a policy of distancing itself from EASA and aligning more closely with the FAA. Or at least had that policy under the last government and has not got round to changing it yet.
The policy extends to preventing aircraft engineers with EASA certification from getting equivalent CAA certificates and working on UK registered aircraft. Instead they must retrain from scratch, despite a lack of qualified engineers crippling the aviation industry at the moment.
