I would like to point out that the CAMO managing the aircraft is the only way to stay in the controlled environment and to get the ARC through the CAMO itself.
The ARC will then last 1 year + 2x 1 year, provided the aircraft remains under the same CAMO.
No airworthiness review is necessary in the 2nd and 3rd year.
This seems to be a good advantage. Morevore there is no more need to apply to CAA for CofA renewal
