Where are the official guidelines for operating an aircraft on an AOC, but privately flown when the owner is on board ?
Good question.
However its like he says in our neck of woods.
His owner left 'my' operation and went to the ops where he is flying (long time ago, when JAROPS was introduced) basically because our principal said: you need to remove the airplane from the AOC and then put it back on when you want to operate "G" with a mx check.
Their principal said, you can do that routenily. (with conditions of course)
