I agree with Dick. We have experienced the same with our private jet. Not only do we have to pay CAsA the $2000+ estimate to have our aircraft 'approved' when nothing has changed on the aircraft, we also have to spend our time and effort educating CAsA as to why our aircraft should be approved. Some of the questions we have been asked that should already be known by the regulator or questions they ask which they already have the access to documents that contain the answer for them, is something I find frustrating. There seems to be little value in the $140 per hour that we pay CAsA not to read our documents.
