What does the acronym DEADS stand for in relation to invalidating a Certificate of Registration?

The acronym DEADS in relation to invalidating a Certificate of Registration stands for Decommissioned, Exported, Address change, Destroyed, and Sold. Each component of this acronym describes a condition under which an aircraft's registration may be considered invalid:

• Decommissioned indicates that the aircraft is no longer in service, thus affecting its registration status.

• Exported signifies that the aircraft has been taken out of the country and is no longer registered in Canada, necessitating a change in registration.

• Address change refers to updates that must be made if the owner’s address changes; failing to do so may invalidate the registration.

• Destroyed denotes that if an aircraft is destroyed, it cannot remain registered.

• Sold means that a change in ownership requires the registration to be updated or invalidated in the context of the previous owner.

These five conditions are explicitly outlined in regulations governing aircraft registration in Canada, establishing a clear framework for when registration becomes invalid.

The other choices contain incorrect terms or arrangements that do not accurately reflect the definitions provided in the regulations regarding the registration of aircraft, which helps clarify why the correct answer is the most appropriate choice.
