Part V - Airworthiness Manual Chapter 549 - Amateur-Built Aircraft

Canadian Aviation Regulations (CARs) 2017-2

Content last revised: 1998/02/17

[Interpretation Provision for Part V Standards

[In these Standards, the passages giving the Minister power to accept or to find unnecessary something without stating criteria for the use of such power are to be interpreted as requiring that the power be used in consideration of two factors only: the airworthiness of the aircraft that is the subject of the acceptation or the finding, or on which an aeronautical product that is the subject of the acceptation or the finding is to be installed, and the aircraft’s level of safety.]


The content of this chapter is based on Part II, Chapter I, Section 1.8 of the Engineering and Inspection Manual at Amendment 29 dated 31 December 1985.

Information Note:

Chapter 507D entitled Flight Authorisation details a new system of flight authorities. However, Chapter 507D cannot be implemented until Air Regulation 211(4) is amended to enable the new concepts. Therefore, not withstanding what is stated in section 549.3(b) of this Chapter the Department of Transport will continue to issue Flight Permits in accordance with the present Air Regulation 211(4) and the E&I Manual until such time as Air Regulation 211(4) is amended.
