Airworthiness Notices - B056, Edition 1 - 14 July 2000Applicability of Foreign Airworthiness Directives in CanadaPurpose The purpose of this notice is to clarify the applicability of airworthiness directives (ADs), issued by foreign aviation authorities, to aircraft registered in Canada. Definitions Within the context of this notice, the following definitions apply:
Issue The Federal Aviation Administration (FAA) is the responsible aviation authority for many U.S. aircraft types registered in Canada. Consistent with the Transport Canada/FAA Bilateral Airworthiness Agreement and Transport Canada (TC) regulations, ADs issued by the FAA against aircraft for which it is the responsible authority, are mandatory in Canada unless superseded by a Transport Canada AD. Some recent FAA ADs have included statements indicating that the AD is applicable only to U.S. registered aircraft. For example, the text: “Who must comply with this AD? Anyone who wishes to operate any of the above airplanes on the U.S. register” could be incorrectly interpreted as meaning that the AD is not applicable to Canadian registered aircraft. Canadian Regulations The Canadian Aviation Regulations (CARs), Part VI, section 605.84 stipulate that an aircraft shall not be flown unless it is maintained in accordance with the requirements of any ADs issued by Transport Canada or the appropriate foreign aviation authority. With regard to the applicability of foreign ADs, CAR 625, Appendix H, article 4, states: “CAR 605.84 recognizes the mandatory status of foreign ADs and equivalent notices issued by the aviation authority that has jurisdiction over the type design of the aeronautical product.” Note that an AD issued by a foreign aviation authority, which does not have jurisdiction over the type design of the aeronautical product affected, does not apply in Canada. For example, an FAA AD issued against a non-U.S. product does not apply in Canada; likewise, a French DGAC AD issued against a U.S. or other non-French product does not apply in Canada. Transport Canada Policy Transport Canada is encouraging the FAA to return to its previous practice of writing its AD applicability statements as generically as possible; specifically, it is being asked to not make further references to U.S. registered aircraft. Regardless of the FAA’s response to this appeal, the following policy continues to apply:
Availability and Sources of ADs Under ICAO, foreign aviation authorities are required to provide TC with all ADs issued by them in respect of aircraft types which are registered in Canada. After review by TC’s Continuing Airworthiness Division, and when confirmed to be applicable in Canada, TC attempts to individually notify the owners of the affected aircraft. However, in accordance with Airworthiness Manual Chapter 593 (Appendix B) of the CARS, “owners of foreign manufactured products should ensure that they receive all continuing airworthiness information directly from the state having jurisdiction over the type design”, and “...owners are responsible for obtaining directly from their manufacturers all continuing airworthiness information, including service bulletins, be they mandated by the state or not”. Owners should also monitor ADs which may be applicable to certified equipment and appliances installed on their aircraft, as TC is usually unable to identify specific owners or aircraft having these products. ADs known to be applicable to Canadian registered aircraft can be determined from the following official Transport Canada sources: 1. The TC Internet AD website at http://www.tc.gc.ca/aviation/aircert/continaw/ad.htm. 2. The quarterly book “Index of Airworthiness Directives Applicable in Canada” (TP9857), available by subscription from Canada Government Publishing, Ottawa, K1A 0S9, telephone (819) 994-1498. 3. Any Transport Canada Centre, or Continuing Airworthiness Division in Ottawa, telephone (613) 952‑4357, facsimile (613) 996‑9178. |
