What is the correct Transport Canada action when a foreign Airworthiness Directive exists for a Canadian-registered aircraft?

• A. The AD applies to all aircraft in all countries
• B. Transport Canada will review and approve that AD in Canada
• C. Transport Canada will reissue that AD in Canada
• D. The AD only applies to aircraft in the country of origin

Answer: (C)

When a foreign Airworthiness Directive exists for a Canadian-registered aircraft, Transport Canada will reissue that AD in Canada. Airworthiness Directives are mandatory safety actions issued by the authority responsible for an aircraft’s design and airworthiness. To ensure Canadian-registered airplanes are held to the same safety standard, Canada mirrors the foreign directive by issuing a Canadian AD with the same required actions, timing, and applicability. This makes the directive legally enforceable for operators in Canada and keeps safety practices aligned with international actions. It isn’t about applying the foreign AD globally or merely reviewing it; it’s about formally issuing a Canadian AD so Canadian operators must comply. It also isn’t limited to the country of origin; it actively applies to Canadian-registered aircraft under Canadian regulations.
