Preamble

General

The content of this chapter is based on the United States Code of Federal Regulations, Title 14, Chapter 1, Part 29 entitled, Airworthiness Standards, Transport Category Rotorcraft. 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 bears the same number as the FAR equivalent, prefixed by the number "5", as this chapter forms part of Series 5 of the Canadian Aeronautics Code.

First Edition

Effective July 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, subchapters, 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 exits, the affected part of text is printed opposite to the FAR with all changes underlined.

The first issue of this chapter is based on FAR Part 29, up to and including amendment 29-24. 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:

* Rotorcraft Operations after Ground Cold Soak, section 529.1301-1;

* Miscellaneous Markings and Placards, use of metric units, section 529.1557, paragraph (c)(3);

Change 529-1

Effective January 1, 1989

This Change incorporates the following amendments to the United States Code of Federal Regulations, Title 14, Chapter 1, Part 29:

Amendment 29-25 "Cockpit Voice Recorders and Flight Data Recorders" provides standards governing the design and installation of cockpit voice recorders and flight data recorders for rotorcraft. Generally, the requirements and parameters for flight recorders are upgraded to the level of the most sophisticated systems available; the use of digital recording equipment will henceforth become the norm. Additionally, uninterrupted sound recording will be required in cockpit voice recorders. At the date of effectivity of this amendment, Air Navigation Order, Series II, No. 13 and 14 do not require cockpit voice recorders or flight data recorders in rotorcraft. The standards in Sections 529.1457 and 529.1549 will not be applicable unless specifically required in the type certificate basis, a unique operational requirement, or voluntary compliance is requested and approved by Transport Canada.

Amendment 29-26 "Rotorcraft Regulatory Review Program; Amendment No. 3" adopts new and revised airworthiness standards for the powerplant and rotor drive systems to changing rotorcraft certification requirements brought on by technological advances. Amendment 29-26 is adopted with the exception of the amendment to 529.1093 subparagraph (b)(1). A variation is presently being developed to require all rotorcraft to demonstrate some capability to operate during flight encounters with snow, without adverse effect on engine operation. Pending approval of this variation the present text of 529.1093(b)(1) is reprinted on the right side of the page.

Information Note:

Changes are identified by brackets [ ]; editorial alterations and typographical corrections are not identified.

Change 529-2

Effective February 1, 1992

This change incorporates the following amendments to the United States Code of Federal Regulations, Title 14, Chapter 1, Part 29:

Amendment 29-27 "Revision of General Operating Flight Rules". This amendment changes a cross reference to Part 91 in Appendix A of Part 29, and therefore it is not applicable in Canada. This FAR change is part of a larger reorganization of the general U.S. operating and flight rules to make them more understandable and easier to use.

Amendment 29-28 "Transport Category Rotorcraft Structural Fatigue Evaluation" (published October 27, 1989). This amendment adds flaw tolerance requirements to the requirements for fatigue evaluations of structures. The amendment also extends the requirements for fatigue evaluations for flight structures only to all critical structures, including landing gear, and requires consideration of operations having a high number of power cycles per hours. This amendment is intended to avoid or reduce catastrophic fatigue failures in transport category rotorcraft.

Amendment 29-29 "Occupant Restraint in Normal and Transport Category Rotorcraft". This amendment adds two dynamic crash impact design conditions for seat and occupant restraint systems and increases the static design load factors for seating devices and items of mass in the cabin or adjacent to the cabin. This amendment also prescribes a shoulder harness for each occupant and adopts human impact injury criteria as a measure for occupant protection for dynamic crash impact conditions.

Amendment 29-30 "Rotorcraft Regulatory Review Program Amendment No. 4". This amendment introduces new and revised airworthiness standards for certification of airframe and related equipment on both normal and transport category rotorcraft. This amendment grew out of a rotorcraft regulatory review program and the recognition by both the U.S. government and industry that updated safety standards are needed. The amendment provides a high level of safety in design requirements, while removing certain unnecessary existing burdens.

Amendment 29-31 "Rotorcraft Airworthiness Amendments Based on European Joint Airworthiness Requirements Proposals". This amendment introduces changes to the airworthiness standards for systems propulsion and airframe for both normal and transport category rotorcraft. In addition, the amendment introduces safety improvements, clarify existing regulations, and standardize terminology. The changes are based on some of the proposals that were submitted to the FAA by the European Airworthiness Authorities. The amendment is intended to achieve increased commonality of airworthiness standards among the respective countries. Transport Canada, Aviation Group shares this objective of international harmonization of airworthiness standards for the certification of civil aircraft.

Amendment 29-32 "Shoulder Harnesses in Normal and Transport Category Rotorcraft". This amendment requires the installation and use of shoulder harnesses at all seats of rotorcraft manufactured after September 1992. In right column a Note states that the applicable Canadian retroactive requirements are being published in Air Navigation Order, Series II, No. 2.

In addition, this Change also introduces:

A Canadian variation to section 529.1093 subparagraph (b)(1). In the Preamble to Change 529-1, it was annotated against FAR amendment 29-26, that the change in requirements for flight tests in snow conditions was not applicable in Canada and that a new requirement was under development. The variation published in this Change has been subjected to consultation with Canadian aviation industry and has received general acceptance. This variation is supplemented by the publication of advisory material AMA 500C/7, dated 27 July 1990, which provides guidance on acceptable means of compliance.

The revision of previous preambles for completeness and clarity.

The publication of the following new or revised advisory material:

AMA 500C/5B Aircraft Operation After Ground Cold Soak dated March 2, 1990.

AMA 500C/6 Lighting Protection of Aircraft Fuel Systems dated Oct. 27, 1989.

AMA 500C/7 Induction System Snow Protection dated July 27, 1990

AMA 500C/8 Composite Aircraft Structures dated Jan. 8, 1991.

Change 529-3

Effective January 3, 1994

This change is the result of FAA NPRM 90-24. The proposed amendment entitled "Crash Resistant Fuel Systems in Normal and Transport Category Rotorcraft" intends to improve the survivability from helicopter crashes resulting in post crash fires. In anticipation of the final rule incorporating this amendment into FAR Part 29 and in harmonization with the JAA, Transport Canada has adopted this proposed amendment. The standards intend to minimize spillage of fuel (and other flammable fluids) near ignition sources, minimize potential ignition sources and improve evacuation time needed for crew and passengers to escape a post crash fire.

The adoption of this rule was object of NPA 93-03.

Second Edition

Change 529-4

Published December 1, 2003

1. General

This change introduces a new format that eliminates the left-hand column containing the FARs. The Canadian standards in this chapter are now presented in a full-page format. Canadian variations and major differences in textual references from the FARs are underlined with the FAR text following in an information note. This change introduces a new amendment format and as a result the change number and date of affected pages has been removed from the bottom of the page. This new amendment format was introduced in chapter 525 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 529-4:

* the preamble will be 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, the amended text will be followed by an amendment tag identifying the coming into force date of the provision. (example: amended (2003-06-01);).

* brackets "[ ]" will no longer be used to identify new or revised text. On 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 tables of change information. These tables will include the Notices of Proposed Amendments (NPAs) with the corresponding amended sections.

With the incorporation of these changes, the entire chapter is republished in a Second Edition.

3. CARAC Proposed Amendment Recommendations

This amendment also implements the recommendations of CARAC Working Group 527/529

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 527/529 Working Group was completed in July 1999 and presented to CARAC Technical Committee V in September 1999. The Civil Aviation Regulatory Committee (CARC) approved all the recommendations on 10 December 1999.

Therefore, this change includes:

Table of Change Information
Notice of Proposed Amendment Amended Section
  • 1995-001
  • 529.807
  • 529.813

These requirements improve exit standards for passenger emergency evacuation in cases where the rotorcraft is resting on its side. These variations were subjected to consultation with Canadian aviation industry through NPA 95-01 and received general acceptance.

The Working Group 527/529 reviewed this variation and recommended changes that were submitted to industry consultation by means of NPA 99-152. The present Canadian variations at paragraph 529.807 (c) and 529.813 (d) were approved by CARC on 10 December 1999. A new Advisory Circular (529-xxx series) contains acceptable means of compliance with these requirements.

The Canadian variation in 529.1581(e) and (f) was cancelled.

The Canadian variation 529.975 (b) was also cancelled as explained in the text of amendment 29-42.

4. Miscellaneous Changes

This change also includes editorial corrections, including the update of cross-references to CARs (e.g. 529.1).

Due to the consolidation of all regulatory requirements previously found in the Air Regulations and Air Navigation Orders into the Canadian Aviation Regulations, administrative changes are included in this amendment to update the regulatory references and terminologies (e.g. Type Certificate instead of Type Approval).

Change 529-5

Published: December 30, 2006

This change incorporates the following amendment to the United States Code of Federal Regulations, Title 14, Chapter I, Part 29:

FAR Amendment 29-45

Effective: June 23, 2003

Table of Change Information
Notice of Proposed Amendment Amended Section
  • 2002-063
  • 529.602

This amendment entitled “Critical Parts” adopts by reference the rotorcraft critical parts requirements of FAR amendment 29-45, dated 25 October 1999, and incorporates the FAA final rule in AWM Chapter 529 in order to harmonize with both the FAA and JAA (now the European Aviation Safety Agency (EASA)).

In 1999, FAA and JAA issued harmonized requirements dealing with the quality assurance of critical parts of rotorcraft. The new requirements contain a definition of “Critical Parts” and require to show compliance with the quality assurance requirements of FAR or JAR Part 21 (superseded by EASA IR Part 21). The FAA and JAA/EASA rules and related advisory material are fully harmonized.

The objective of the rule is to create a rotorcraft critical part list to ensure that critical parts are controlled during design, substantiation, manufacturing and throughout their service life (maintenance and modifications).

Information Note:

FAA and JAA published advisory material: AC/ACJ 29.602. This Advisory Circular is acceptable in Canada.

Change 529-6

Published: June 30, 2008

This change incorporates the following amendments to the United States Code of Federal Regulations, Title 14, Chapter I, Part 29:

Table of Change Information
Notice of Proposed Amendment Amended Section
  • 2007-018
  • 529.67

This amendment entitled “Climb: One-Engine Inoperative” adopts by reference a correction to AWM Chapter 529 paragraph 529.67(a)(2), which has not yet been captured. The FAA Federal Register volume 64, page 45337, dated 19 August 1999 provided a change to the noted paragraph.

Paragraph (a)(2)(ii) is [now] deleted because the requirement is previously stated in Sec. 29.64. The deletion of paragraph (a)(2)(ii) resulted in an editorial renumbering of paragraphs (iii) and (iv) as (ii) and (iii) respectively.

The above correction affects only the English text of the CARs since the error originated with the FARs. As a result, the French text is untouched. This explains the discrepancy associated with the Amendment dates tags for the English text (July 16, 2007) and the French text (April 7, 1997).

This amendment entitled “Airworthiness Standards; Electrical and Electronic System Lightning Protection” revises the airworthiness standards applicable to transport category rotorcraft by establishing new lightning protection standards for electrical and electronic systems installed on aeroplanes certified under AWM Chapter 529.

This amendment establishes two levels of lightning protection for rotorcraft 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 rotorcraft or the ability of the flight crew members to respond to an adverse operating condition. This standard also establishes lightning protection for rotorcraft systems according to the rotorcraft’s potential for lightning exposure. The airworthiness standards establish consistent lightning protection requirements for rotorcraft electrical and electronic systems.

This amendment entitled “Damage Tolerance and Fatigue Evaluation of Composite Rotorcraft Structures” revises the airworthiness standards for type certification requirements of normal and transport category rotorcraft. The amendment requires evaluation of fatigue and residual static strength of composite rotorcraft structures using a damage tolerance evaluation, or a fatigue evaluation if the applicant establishes that a damage tolerance evaluation is impractical and addresses advances in composite structures technology and provides internationally harmonized standards.

The Minister shall issue type certificates for aircraft, aircraft engines, propellers, and specified appliances when the Minister finds the product is properly designed and manufactured, performs properly, and meets the regulations and minimum standards. This amendment is within the scope of these authorities because it will promote safety of composite structures by updating the existing minimum prescribed standards, used during the type certification process, to address advances in composite structural fatigue substantiation technology. It will also harmonize this standard with international standards for evaluating the fatigue strength of normal and transport category rotorcraft composite primary structural elements.

This amendment entitled “Fatigue Tolerance Evaluation of Metallic Structures” revises the airworthiness standards for fatigue tolerance evaluation (FTE) of transport category rotorcraft metallic structures. This revises the FTE safety requirements to address advances in structural fatigue substantiation technology for metallic structures. This provides an increased level of safety by avoiding or reducing the likelihood of the catastrophic fatigue failure of a metallic structure. These increased safety requirements will help ensure that should serious accidental damage occur during manufacturing or within the operational life of the rotorcraft, the remaining structure could withstand, without failure, any fatigue loads that are likely to occur, until the damage is detected or the part is replaced. Besides improving the safety standards for FTE of all principal structural elements (PSEs), the amendment is harmonized with international standards.

Rotorcraft fatigue strength reduction or failure may occur due to aging, temperature, moisture absorption, impact damage, or other factors. Since a reduction in strength of any primary structural element can lead to a catastrophic failure, it is important to evaluate fatigue tolerance.
