SI 513-009, Issue 01, 2006-04-01 —Part Design Approval Procedures.
Aeronautical Product: an aircraft, aircraft engine, aircraft propeller or aircraft appliance or part, or a component part of any of those things, including any computer system and software (Ref. Aeronautics Act and Section 521.01 of the CARs). This SI does not apply to products approved by a Canadian Technical Standard Order (CAN-TSO) design approval.
Certification Basis: refers to the applicable standards as established in Section 521.157 of the CARs, as appropriate, including any special conditions—airworthiness (SCA), findings of equivalent level of safety, and exemptions applicable to the product to be certified.
National Aeronautical Product Approval (NAPA) System: an automated system that provides staff in aircraft certification with the tools necessary to track the certification of aeronautical products and issue the design approval documents. This system also provides a database of the projects and supporting data for this certification.
Part Design Approval (PDA): a document that is issued by the Minister to record the approval of the type design of a replacement part, identified by a part number or by some other means of identification unique to the part, for use on an aeronautical product that is identified by type or model (Subsection 101.1(1) of the CARs).
Standards of Airworthiness: design requirements as defined in the AWM. For design changes, the standards of airworthiness may also be listed on the type certificate data sheet (TCDS).
the airworthiness limitations section of the instructions for continued airworthiness (ICA) specified in the applicable chapters of the AWM; and
(Ref: Section 101.01 of the CARs).
With the implementation of Subpart 521 of the CARs new documents have been created to support the regulations. All guidance material such as SIs, ACs and Policy Letters, that supported the previous CARs including Chapters 511, 513, 591 and 593 of the AWM have been reviewed and the relevant material included in the 521 series ACs and SIs.
This SI is organized to mirror Sections and Subsections of Division VII of Subpart 521 of the CARs, so that it can be easily read in conjunction with Subpart 521 of the CARs.
Although Subpart 521 of the CARs introduced a change in terminology in the English version from “compliance” to “conformity” this SI will be using “compliance” wherever possible to minimize confusion.
The PDA was introduced to allow the approval of replacement parts where the design of that replacement part represents a negligible change to the fit, form and function of the part it is intended to replace. The replacement part must meet the applicable airworthiness requirements as stated in the TCDS of the original equipment manufacturer product. In addition, the replacement part does not enhance the functionality of the part it is intended to replace, nor of the aeronautical product on which the part is installed.
The requirements that must be fulfilled to obtain a PDA as a result of a replacement part are defined in Divisions IV, Changes to a Type Design and VII, Part Design Approvals of Subpart 521 of the CARs,. This SI should be used in conjunction with SI 521-004.
Sections 521.301 to 521.303 of the CARs define the requirements of an applicant for a PDA. Sections 521.304 and 521.305 of Division VII of the CARs and Sections 521.157 to 521.160 of Division IV of the CARs establish the certification requirements as well as the requirements for demonstrating that the replacement part complies with all certification requirements. Sections 521.306 and 521.307 of Division VII of the CARs and Section 521.161 of Division IV of the CARs define the design approval issuance and subsequent revision requirements.
This SI applies to applications for a Canadian PDA under Division VII of Subpart 521 of the CARs.
Any Canadian individual or organization may apply for a PDA. Canadian design approval documents are not issued directly to foreign applicants. Refer to Division XI of Subpart 521 of the CARs for more information on foreign aeronautical products.
Section 521.302 of the CARs requires the applicant to have or have access to the required technical capabilities specific to the replacement part under consideration. An applicant could meet this requirement by:
Having a level of knowledge and capability appropriate for the replacement part, or;
Showing that an arrangement exists for the applicant to have access to a level of knowledge and capability appropriate for the replacement part.
For more detailed information on how the Minister determines technical capability, refer to AC 521-002.
Applications for a PDA are processed in accordance with the procedures defined in SI 521-004.
The replacement part shall not:
be subject to an airworthiness limitation;
be a standard part or a commercial part;
constitute a change to the type design of the aeronautical product; or
create an airworthiness limitation.
See AC 521-007 for a complete list of eligibility criteria for PDAs.
Establishment of the certification basis is to be conducted in accordance with Subsection 521.158(2) of the CARs.
SI 521-004 provides information on establishing means of compliance and TCCA’s level of involvement.
The applicant’s compliance demonstration with the certification basis is to be conducted in accordance with the procedures defined in SI 521-004 (Section 521.160 of the CARs).
In addition to any compliance issues specified in SI 521-004 (Section 521.160 of the CARs), the following specific issues should be considered for PDAs:
Part marking; and
Methods of analyses (computation), inspections and test. Certification by inspection only, i.e. identicality is not sufficient means to satisfy compliance with the certification basis.
Issuance of a PDA is to be conducted in accordance with the procedures defined in SI 521-004 and the guidance provided in this section.
A sample PDA is provided in Appendix A of this SI.
The certificate format and numbering system for PDAs is as described in Appendix B of this SI.
Only an appropriately authorized TCCA employee may issue PDAs.
A PDA-specific Approval Document Checklist is provided in Appendix D of this SI. This checklist should be used in conjunction with the project checklist provided in SI 521-004.
A transmittal letter template is provided in Appendix E of this SI.
Additional guidance on the issuance of approvals for a change to a type design is provided in SI 521-004.
Revisions for the purpose of adding references to new or revised engineering data, or for incorporating other necessary changes or corrections, shall be annotated with a vertical bar adjacent to the right hand margin to indicate the changes on the certificate.
A change to a PDA that is classified as a major change (not minor) shall be applied for as either a new PDA (replacement part that does not modify the baseline aeronautical product), or shall be applied for as an supplemental type certificate (STC) that is separate from the original PDA, the new change being a modification of the baseline aeronautical product.
Minor changes shall be dealt with in accordance with Section 521.154 of the CARs.
TCCA files will retain key compliance related information such as certification plans, issue papers and decision records as well as any data cited on the approval document such as flight manuals and supplements, maintenance manuals/Instructions for Continued Airworthiness (ICA) and master document lists.
