That last sentence is not correct. An aircraft in the uncontrolled environment cannot have its ARC extended by a Part-66 engineer, or by a CAMO for that matter. In the uncontrolled environment the aircraft has to have an airworthiness review - and a new ARC issued - each year. Extending the ARC can only be done for aircraft in a controlled environment.
