C.A.M.O.
Sorry if this one has already been done to death, but I'm researching the charges made by maintenance organisations for ongoing charges under the C.A.M.O. scheme. As usual, there seem to be wild differences between them.
By the way, I understand that the value of Permit aircraft has increased significantly since the start of the scheme, as owners finally get fed up with the costs involved in running aircraft that require a C of A.
