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).

The following changes to the amendment procedures are introduced in this Change 537-5:

  • the preamble will become the focal point regarding the sections affected by this Change. The change number will no longer be provided at the end of an amended section. Rather, for the current change only, an amendment tag identifying the "coming into force date" of the provision will follow the amended text. (example: (amended 2003/06/01)).
  • brackets "[ ]" will no longer be used to identify new or revised text. In the paper version, new or revised text will be highlighted. In the electronic version, new or revised text will not be highlighted but followed by an electronic link to the previous version of the modified text. (example: (amended 2003/06/01; previous version)).
  • the preamble will include a table of change information. This table will include the Notices of Proposed Amendments (NPAs) with the corresponding amended sections.

  • 1998-284
  • 537.207

With the publication of the Canadian Aviation Regulations (CARs) in 1996 and the revocation of the Engineering and Inspection Manual (E&I Manual), some information contained in Part II, Chapter III, section 3.12 of the E&I Manual regarding emergency locator transmitters (ELT), especially ELT batteries, would be lost. The CARAC Equipment Standards – Airworthiness Manual 551/537 Working Group studied the above problem and recommended that a new section be added to Chapter 537 of the Airworthiness Manual to capture information that will be left out as a result of the revocation of the E&I Manual.

Change 537-12

Published: December 1, 2009

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 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.

This amendment updates the list of Transport Canada adopted Canadian Technical Standard Orders (CAN-TSOs) with the following changes:

  • instead of explicitly referring to a revision of each TSO (CAN-TSO, FAA TSO or ETSO) listed in Appendix A (index 1 and Index 2), each TSO is referred to with a generic revision level, as amended from time to time (open brackets).
  • new issues of FAA TSOs, added to the FAA list of current TSOs between April 1st, 2022 and July 11, 2023, are incorporated by reference.
  • This modifications incorporates by reference newly issued EASA European Technical Standard Orders (ETSOs) of the 2C5XX series introduced in Amendment 17 of CS-ETSO, Subpart B, Index  2, and all other Index 2 ETSOs (non-2C5XX series), that were previously not incorporated. With this change, all ETSOs that form part of Index 2 to Subpart B of CS-ETSO - Amendment 17, are incorporated by reference.

With this amendment, it is no longer necessary to update the list of CAN-TSOs in Appendix A to adopt new revisions of FAA TSOs or ETSOs that are already listed, since these revisions are automatically incorporated by ambulatory reference.

This amendment removes the explicit end of effectivity date from the table of CAN-TSOs in Appendix A. Instead, it is specified that the effectivity of each listed CAN-TSO corresponds to the effectivity of the corresponding FAA TSO or ETSO that is incorporated by reference, as it is amended from time to time.

CAN-TSOs that are not effective are no longer eligible for use by an applicant for a new CAN-TSO design approval, but designs approved under historical CAN-TSOs may continue to be manufactured by an appropriately authorized manufacturer, subject to the conditions of their manufacturer approval.

In addition, this amendment makes an administrative update to the internet link for the procurement of referenced TSOs.

537.103 Canadian Technical Standard Orders

(effective 2023/11/17)

  • (a) The Canadian Technical Standard Orders (CAN-TSOs) consist of those Federal Aviation Administration (FAA) Technical Standard Orders (FAA-TSOs), European Union 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:
    • (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 and revision letter. The effective revision of an Index 1 CAN-TSO is the same as the effective revision of the FAA-TSO of the same number at any given time, as published by the FAA.
    • (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 and using the same numbering and revision. The effective revision of an Index 2 CAN-TSO is the same as the effective revision of the ETSO of the same number at any given time, as specified in the Executive Director (ED) Decision that accompanies the current CS-ETSO amendment.
    • (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:

      • (i) CAN-TSO-3CXXX, in which the 3 denotes that it is from Index 3.

        Information Note: CAN-TSO-3C7XX series denotes CAN-TSOs for which neither an FAA-TSO nor an ETSO exists for a particular application.

      Information Note: The applicant for and user of a CAN-TSO is encouraged to confirm its suitability for use in meeting any applicable design, installation and/or operating rules.

  • (b) Where a CAN-TSO is not effective anymore, applications for CAN-TSO design approvals with respect to these standards will no longer be accepted.

Appendix A

List of Canadian Technical Standard Orders (Index 1, Index 2 and Index 3)

(effective 2023/11/17)

Index 1

Each CAN-TSO listed in this Index 1 incorporates the FAA-TSO listed in the corresponding row with the same revision letter, denoted by the brackets ( ) following the CAN-TSO and FAA-TSO numbers.

Any TSO revision introduced by the FAA and published on the FAA website is equally adopted by the Minister as a revision of the corresponding CAN-TSO listed in this Index 1 on the effective date of the corresponding TSO amendment and remains effective until it is superseded, as may be done from time to time. The end of effectivity date, if applicable, for the CAN-TSO incorporating a particular FAA-TSO is included in the Applicability section of the newly introduced revision of that FAA-TSO. A CAN-TSO incorporating a TSO cancelled by the FAA remains effective at the last effective revision if it is listed in this Index 1.

Information Note: as of the date of this publication, the current and past amendments of FAA-TSOs can be retrieved from the FAA website at the following link: https://drs.faa.gov/browse/TSO/doctypeDetails
