The sticking point might be the CEO role, given that we're talking about a number of legal entities signing up, all with their own CEOs, so who wears the responsibility for ensuring adequate provision of facilities and equipment for each base? Don't get me wrong, I really like the concept, but that's possibly one factor they'll home in on as to why they flip-flopped and said they objected to it after apparently being fully happy for years.
That's the simplest answer, the HOFO/CP is responsible for ensuring each base has the required documentation and adequate facilities or the operation stops until such time there are. The CFI is responsible on location to see they are used and obeyed. The entities at the coal face of the other companies are not flying staff, they run the 'Club' let's say, not much to do with the compliance just financial and asset management. That's the way I see it anyway.
