Interpretation Provision for Part V Standards

In these Standards:

1. (a) The passages giving the Minister the power to determine, approve, establish or authorise something without stating the criteria for the use of such power are to be construed as requiring that the power be used in consideration of two factors: the airworthiness of the appliance or part that is the subject of the determination, approval or authorisation, or of the aircraft on which the appliance or part that is the subject of the determination, approval or authorisation is to be installed, and the aircraft's level of safety;
   (amended 2009/12/01)
2. (b) the word "approved" or "authorised", when used without an indication of a method of approval or authorisation, is to be construed as referring to an approval or an authorisation granted under the Aeronautics Act.
   (amended 2009/12/01)

1. (a) A revised list of Aviation Technical Standard Orders in Subchapter B, based on Advisory Circular AC 20-110J, Appendix 1, dated May 30, 1997, including TSO-C149 and TSO-C150 published by FAA after May 30, 1997 . This change was subjected to consultation with the aviation industry through NPA 1998-174, dated 19 August 1998, and has received general acceptance;
2. (b) Cross reference criteria between FAR and Canadian regulations, that were previously contained in AMA 537/1, and the AMA has been canceled. This change was subjected to consultation with the aviation industry through NPA 1994-16, dated 20 December 1994, and has received general acceptance; and
3. (c) The addition of an Information Note after paragraph 537.205 (c).

Information note:

Effective 1 December 1998 a new Chapter 551of the Airworthiness Manual, entitled "Aircraft Equipment and Installation Standards" has been published. This chapter contains the acceptable design standards as well as installation standards for use by installers and users of these items of equipment.

Chapter 537 "Appliances" of this manual remains valid; it specifies the current standards for issuance of a Type Certificate for new aviation appliances and is designer / manufacturer oriented.

1. General

This change introduces a new amendment format. This new amendment format is introduced in Chapter 537 of the Airworthiness Manual in order to be more consistent with the administrative procedures followed to amend the Canadian Aviation Regulations (CARs).

This amendment updates the list of Transport Canada adopted Technical Standard Orders (TSOs) with those recently amended and published TSOs identified from the FAA list of current TSOs, as modified between May 17, 2007 and February 6, 2009. The adoption of these FAA TSOs is in order to harmonize section 537.103 with the FAA's current list of TSOs.

On December 1, 2009, Part V Subpart 21 of the Canadian Aviation Regulations (CAR 521) came into force. CAR 521 replaces the following Regulations in Part V - Airworthiness:

Subpart 11 - Approval of the Type Design of an Aeronautical Product
Subpart 13 - Approval of Modification and Repair Designs
Subpart 16 - Aircraft Emissions
Subpart 22 - Gliders and Powered Gliders
Subpart 23 - Normal, Utility, Aerobatic and Commuter Category Aeroplanes
Subpart 25 - Transport Category Aeroplanes
Subpart 27 - Normal Category Rotorcraft
Subpart 29 - Transport Category Rotorcraft
Subpart 31 - Manned Free Balloons
Subpart 33 - Aircraft Engines
Subpart 35 - Aircraft Propellers
Subpart 37 - Aircraft Appliances and Other Aeronautical Products
Subpart 41 - Airships
Subpart 51 - Aircraft Equipment
Subpart 91 - Service Difficulty Reporting
Subpart 93 - Airworthiness Directives

In addition, with publication of CAR 521, the following Chapters of the Airworthiness Manual have been withdrawn:

Chapter 511 - Approval of the Type Design of an Aeronautical Product
Chapter 513 - Approval of Modification and Repair Designs
Standard 591 - Service Difficulty Reporting
Standard 593 - Airworthiness Directives

This change amends Chapter 537 of the AWM to reflect changes in legal drafting style, in terminology and in references required because of the introduction of CAR 521.

Subchapter A is amended to refer to the new Canadian Technical Standard Order (CAN-TSO) design approval and to make related changes.
The general provisions of Subchapter B have been modified to reflect our new CAN-TSO and to add a new column to the table to provide the CAN-TSO number that corresponds to the adopted FAA TSO.

Subchapter C is amended to delete section 537.203 on child restraint systems, which is now part of Chapter 551 of the AWM.

 

This change contains the following:

This amendment updates the list of Transport Canada adopted Canadian Technical Standard Orders (CAN-TSOs) with those recently amended and published CAN-TSOs identified from the FAA list of current TSOs, as modified between February 7, 2009 and December 17, 2009. The adoption of these FAA TSOs harmonizes section 537.103 with the FAA's current list of TSOs.

In addition, editorial revisions to the section and paragraph numbering of 537.101 and 537.103 are made to restore the location of adopted FAA TSOs to section 537.103. Continued use of section 537.103 to identify those adopted FAA TSOs will simplify and therefore better enable ongoing determination of historical and current effective dates of FAA TSOs in Canada, through the use of the CARAC Notice of Proposed Amendments System database search function, allowing the use of the single search criteria of "537.103" to obtain an appropriate listing.

(effective 2015/08/04)

537.103 Canadian Technical Standard Orders

(effective 2015/08/04)

1. (a) The Canadian Technical Standard Orders (CAN-TSOs) consist of those Federal Aviation Administration (FAA) Technical Standard Orders (FAA-TSOs), European Aviation Safety Agency (EASA) European Technical Standard Orders (ETSOs) and those unique Canadian CAN-TSOs that are adopted by the Minister, using the simplified process for the amendment of the design standards of airworthiness, as set out in the Canadian Aviation Regulation Advisory Council Management Charter, and are identified with a corresponding CAN-TSO number as follows:
   (effective 2020/01/23)
   1. (1) Index 1 of Appendix A to this Chapter consists of those CAN-TSOs identical to those used by the FAA and using the same numbering.
      (effective 2015/08/04)
   2. (2) Index 2 of Appendix A to this Chapter consists of those CAN-TSOs identical to those used by EASA, as listed in CS-ETSO Subpart B Index 2, only for those Index 2 ETSOs where an FAA-TSO does not exist for a particular application (i.e. ETSO-2C5XX series), and using the same numbering.
      (effective 2015/08/04)

      Information Note: The applicant for and user of an Index 2 CAN-TSO is encouraged to confirm its suitability for use in meeting any applicable design, installation and/or operating rules.
      (effective 2017/11/25)

   3. (3) Index 3 of Appendix A to this Chapter consists of those CAN-TSOs that have been developed by the Minister and issued pursuant to paragraph 521.106(b) of the Canadian Aviation Regulations, where these CAN-TSOs are not technically similar to either FAA-TSOs or ETSOs and will be numbered as follows:
      (effective 2015/08/04)
      1. (i) CAN-TSO-3CXXX, in which the 3 denotes that it is from Index 3.
