And to note, an invalid registration also invalidates the AWC by rule. However, any host country NAA where the aircraft domiciles can generate their own rule to allow any of the affected aircraft to fly if needed, but only within that country's NAA jurisdiction. For example, Canada's TCCA created an owner maintained category of aircraft that allows the owner to perform maintenance on any of the eligible type-certified aircraft. Except those aircraft are permanently marked and not permitted to be exported or flown in other countries.
Cancelling the registration probably affects the ability to get an export C of A issued. This needs handling with care as making the situation worse is a possibilty.
