The CAA review will have to address their own lack of manpower to oversee and enforce any future increase in their breadth of regulation.
There are still loopholes in Part NCC, or any other regulations. As far as minimum weather conditions are concerned, at private landing sites, some of which may be used on a "one off" basis, who is to say what the visibility actually was, apart from the pilot on the day? The pilot will still have to take the flak when he tells the aircraft owner that the flight cannot go ahead in conditions that were acceptable in the past. Therein lies the problem.
