Preamble
General
The content of this chapter is based on the United States Code of Federal Regulations, Title 14, Chapter 1, Part 23 entitled "Airworthiness Standards, Normal, Utility, Acrobatic and Commuter Category Aeroplanes". These United States airworthiness standards have been used and adapted as the model for the Canadian standards supplemented by additional airworthiness requirements based on Canadian experience and required for Canadian aviation purposes.
The FAR numbering system is used. The Canadian standards bear the same number as the FAR equivalent, prefixed by the number "5", as this chapter contains the standards for Part V of the Canadian Aviation Regulations (CARs).
First Edition
Effective - January 1, 1986
The standards in this chapter are presented in a two column format with the United States FAR in the left column and the Canadian standards in the right column. Chapters, sub-chapters, sections and subsections numbering and headings are opposite to the equivalent FAR. Where the Canadian standard is identical to the FAR, the words "No Variation" appear; where a variation exists, the affected part of text is printed opposite to the FAR with all changes underlined.
The first edition of this chapter is based on FAR Part 23, up to and including amendment 23-31. In addition to administrative changes (e.g., Administrator = Minister; Part = Chapter) and the deletion of references to operating FARs, the Canadian variations included in this edition are as follows:
Miscellaneous Markings and Placards: use of metric units, Section 523.1557 paragraph (c)(4);
Aeroplane Flight Manual: use of metric units paragraph 523.1581(e) and reference to operating rules, paragraph (f);

Change 523-3:
Effective - January 2, 1992
This change incorporates the following amendments to the United States Code of Federal Regulations, Title 14, Chapter 1, Part 23:
Amendment 23-37 "Revision of General Operating and Flight Rules" affects U.S. operations only and is not applicable in Canada.
Amendment 23-38 "Airworthiness Standards; Fatigue Requirements" which adopts fatigue requirements for empennage, canard, tandem wing and winglet/tip structures. Service history has shown the need to consider empennage fatigue strength during type certification. Also, due to recent design developments where conventional wing and empennage configurations are being replaced or modified by canard, tandem wing and winglet/tip fin structures, fatigue requirements for these new structures are also included.
Amendment 23-39 "Airworthiness Standards; Commuter Category Aeroplanes" is based on the requirements adopted by FAR amendment 23-34 and specifies take off height and performance airspeeds requirements.
Amendment 23-40 "Fuel Venting and Exhaust Emission Requirements for Turbine Powered Aeroplanes" which requires compliance with the new Part 34. Part 34 consolidates all of the applicable aircraft engine fuel venting and exhaust emission requirements of SFAR 27-5, and the test procedures specified under the U.S. regulations implementing the Clear Air Act of the United States of America. In lieu of Part 34, Transport Canada has adopted the standards of Annex 16 to the Convention on International Civil Aviation, Volume II entitled "Aircraft Engine Emission," First Edition - 1981, published by ICAO. Accordingly sections 523.903 and 523.951 are amended to refer to chapter 516, Second Edition, Subchapter B.
Amendment 23-41 amends the airworthiness standards for equipment, systems and installations, and establishes airworthiness standards for the installation of electronic display instrument systems in normal, utility, acrobatic and commuter category aeroplanes. This amendment resulted from the FAA's Small Aeroplane Airworthiness Review Program Amendment No. 5.
Amendment 23-42 provides airworthiness standards for advancements in technology being incorporated in current designs, permits type certification of spin resistant aeroplanes, and reduces the regulatory burden in showing compliance with some of the requirements for the design and type certification of small aeroplanes.

Change 523-4:
Effective - 1 September 1996
This change incorporates the following amendments to the United States Code of Federal Regulations, Title 14, Chapter 1, Part 23:
Amendment 23-43 "Small Aeroplane Airworthiness Review Program, Amendment No. 3" which amends the powerplant and equipment airworthiness standards for normal, utility, acrobatic and commuter category aeroplanes. This amendment is based on certain proposals and recommendations discussed at the Small Aeroplane Airworthiness Review Conference held on October 22-26, 1984 in St. Louis, Missouri, and arises from the recognition by both government and industry, that upgraded standards are needed to maintain an acceptable level of safety for small aeroplanes. The adoption of this FAA amendment was object of Canadian NPA 93-06.
Amendment 23-44 "Airworthiness Standards, Small Aeroplanes with Stall Speed Greater than 61 knots", which amends the stalling speed requirements applicable to single-engine aeroplanes and to certain multi-engine small aeroplanes of less than 6,000 pounds maximum weight. The rule permits those aeroplanes to have a stall speed greater than 61 knots, provided they meet certain additional occupant protection standards. These amendments are needed to permit the design and type certification of higher performance aeroplanes with increased cruise speeds and better specific fuel consumption. The amendments are intended to achieve the benefits of certificating higher performance aeroplanes while affording their occupants the same level of protection in an emergency landing that is presently provided by aeroplanes with a 61-knot stall speed. The adoption of this FAA amendment was object of Canadian NPA 93-09.
Amendment 23-45 "Small Aeroplanes Airworthiness Review Programs, Amendment No. 4", which changes airframe and flight airworthiness standards for normal, utility, acrobatic and commuter category aeroplanes. The amendments are based on a number of recommendations discussed at the Small Aeroplane Airworthiness Review Conference held on October 22-26, 1984, in St. Louis, Missouri. These updated safety standards will continue to provide an acceptable level of safety in the design requirements for small aeroplanes used in both private and commercial operations. Some of the amendments provide design requirements applicable to advancements in technology being incorporated in current designs. This amendment will also reduce the regulatory burden in showing compliance with some requirements while maintaining an acceptable level of safety. The adoption of this FAA amendment with the exception of section 23.573, was object of Canadian NPA 93-11.
This amendment also includes:
Canadian Variation to section 523.573, paragraph (a)(5) was object of Canadian NPA 94-11 dated 20 August 1994.
FAR section 23.573 "Damage Tolerance and Fatigue Evaluation of Structure" which is introduced as part of Amendment 23-45, and concerns aeroplane designs that make extensive use of composite materials, including bonded joints. This section contains the provisions of the earlier FAA Special Conditions, entitled "Evaluation of Composite Structure" in which a paragraph was devoted to the strength of bonded joints and was intended to ensure that disbonding did not result in a level of strength less than that necessary to carry limit loads.
The Enabling Authority has been replaced by the reference to the Canadian Air Regulations in subsection 523.1(a)
The renumbering of paragraph 523.1581(f) and (g) as 523.1581(g) and (h) because of the incorporation of FAR Amendment 23-45.
The publication of the following advisory material:
AMA 500C/8A | Composite Aircraft Structure, dated 1 September 1996. |
---|---|
AMA 500/9 | Standards For The Design And Installation of Aircraft Skis, dated 1 September 1996. |

3. CARAC Working Group
This amendment also implements the recommendations of CARAC Working Group 523-525.
In 1996 the integration of the existing Design Standards of this Manual into the new Canadian Aviation Regulations (CARs), Part V was delayed as a result of a request by Canadian aviation industry to review these standards, in particular the Canadian variations, and all associated Canadian advisory material (AMAs) for their accuracy and appropriateness.
Due to the time frame for CARs implementation, the CARAC Airworthiness Technical Committee V formed several Working Groups made up of industry and Transport Canada specialists to review those variations, AMAs and any applicable Special Conditions and make recommendations to the Committee for their disposition.
The final report of the 523/525 Working Group was completed in June 1997 and all its recommendations were accepted by the CARAC Technical Committee V. With the publication of this Change to Chapter 523, Transport Canada Civil Aviation, Aircraft Certification Branch, starts the implementation of those recommendations.
Therefore, this change includes:
-
(a) The cancellation of Canadian variation 523.573 (a)(5), which is superseded by the adoption of FAR Amendment 23-48, effective 30 June 1997. The related AMA 500C/8A was revised to ensure consistency in interpretation and application of the requirements related to bonded joints. (NPA 2000-93)
-
(b) The cancellation of Canadian variations:
523.1581(g) and (h) effective on the date of publication of this change. (NPAs 2000-94 and 2001-012)

4. Miscellaneous Changes
This change also includes editorial corrections, including the update of cross references to CARs (e.g. 523.1).
Due to the consolidation of all regulatory requirements previously found in the Air Regulations and Air Navigation Orders into the new Canadian Aviation Regulations, administrative changes are included in this amendment to update the regulatory references and terminology (e.g. Type Certificate instead of Type Approval).
Change 523-6:
Effective - December 1, 2004
In an effort to harmonize our regulatory guidance documents with those of other international aviation authorities and other branches within Transport Canada Civil Aviation (TCCA), the Aircraft Certification Branch has decided to replace existing Airworthiness Manual Advisories (AMA) related to certification of aeronautical products with new Advisory Circulars (AC). While the content of the new ACs will remain technically the same as the corresponding AMAs, which they will replace, the format of the ACs will be standardized to conform to other guidance documents published within the branch.
This change in guidance documentation becomes effective 1 December 2004 at which time the AMAs will be cancelled and replaced by their corresponding Advisory Circular concurrent with the next publishing of the Canadian Aviation Regulations (CAR). After this time, the CARAC Secretariat will no longer publish these AMAs and, consequently, ACs will not be published with their corresponding AWM Chapter. As of the 1 December 2004 issue of the CARs, any affected AMA references and content will have been removed. However, the AMA Index found in AMA 500/00 will, for now, continue to exist to provide a cross-reference between the old AMAs and the new ACs.
Change 523-7:

The purpose of this proposal is to harmonize the Airworthiness Manual section 523.961 with FAR Part 23 corrected 23.961.
FAR Amendment No. 23-43 was published in the US Federal Register, Vol. 58, No. 67, dated April 9, 1993 with an effective date of May 10, 1993. However, prior to its effectivity, the FAA promulgated a correction in 58 FR 27060 on May 6, 1993, which corrected the "100º F" to instead read "110º F" at section 23.961.
TCCA did not make note of the promulgated correction and issued NPA 93-06 to adopt Amendment No. 23-43 (uncorrected) that became effective in the Airworthiness Manual on September 1, 1996.

This amendment establishes two levels of lightning protection for aeroplane systems based on consequences of system function failure: catastrophic consequences which would prevent continued safe flight and landing; and hazardous or major consequences which would reduce the capability of the aircraft or the ability of the flight crew members to respond to an adverse operating condition. This standard also establishes lightning protection for aeroplane systems according to the aircraft's potential for lightning exposure.
Existing airworthiness standards for the lightning protection of electrical and electronic systems installed on aircraft certified under AWM Chapters 523, 527 and 529 require the type certification applicant only to "consider" the effects of lightning. Unlike system lightning protection airworthiness standards for transport category aeroplanes, these airworthiness standards have not been significantly amended since they were first established, and do not reflect current advances in technology.

This amendment entitled “Revision of Airworthiness Standards for Normal, Utility, Acrobatic, and Commuter Category Airplanes” amends the design standards in this Chapter by incorporating the requirements of amendment 23-64 to the Federal Aviation Regulations, Part 23, as published in the Federal Register, Volume 81, No. 251, on December 30, 2016.
This amendment replaces current prescriptive design requirements with performance-based airworthiness standards. These standards also replace the current weight and propulsion divisions with performance- and risk-based divisions for aeroplanes with a maximum seating capacity of 19 passenger and a maximum takeoff weight of 19,000 pounds. These airworthiness standards are based on, and will maintain, the level of safety of the current Chapter 523, except for areas addressing loss of control and icing, for which the safety level has been increased. Through this amendment Transport Canada adopts additional airworthiness standards for flight in icing conditions, enhanced stall characteristics, and minimum control speed to prevent departure from controlled flight for multiengine aeroplanes.
