Hi JXK so what your say is after the initial rush when subpart G was launched owners are now managing their aircraft them selfs.So these aircraft are being maintained outside the controlled environment and are requiring their ARC's to be issued yearly by the CAA or a CAMO.Isnt the ARC fee's every year a bit of a pain.
Correct - Owners keep their logbooks up together and at the specified maintenance times contact their MO to schedule the necessary work. A part G organisation with sub part I can then issue the ARC after the part F has done the work.
In the case of a MO with both G & F the whole operation is synchronised and there doesn't have to be 2 way communication between the different organisations.
