EASA has brought us many more rules, making things far more difficult (for those legally plying their trade) to make a living.
However, it seems to have left some large loopholes through lack of enforcement
The enforcement is done through the competent authority. Now how that works for a dodgy N reg in Europe I am not sure... My gut feeling says that the CAA is the competent authority so they would be the enforcement agency, not EASA.
