Sub-base(s)
A maintenance facility under the control of the AMO located in the AMO’s principal origin/country of business as well as at other locations identified in the relevant manual which are subject to the oversight of the Competent Authority. Maintenance may not be performed outside of Canada or the EU, in countries where existing agreements or arrangements are in place with the Competent Authority for the performance or acceptance of maintenance.

Introduction

The Maintenance Annex Guidance (MAG), is sub-divided into three sections;

• Section A: Competent Authority Interaction
• Section B: Approval Process for Canadian Approved Maintenance Organizations
• Section C: Approval Process for EU Approved Maintenance Organizations

The MAG details the actions required by TCCA, EASA, the Competent Authorities (CAs), and applicants to be taken in order for a TCCA CAR 573 Approved Maintenance Organization (AMO) to maintain civil registered aircraft under the jurisdiction of a European Union Member State. It also details the actions for an EASA Part-145 AMO to maintain civil registered aircraft under the jurisdiction of Transport Canada. All in accordance with the agreement on Civil Aviation Safety between the European Union and Canada (the Agreement).

The Canadian requirements for maintenance are contained in Canadian Aviation Regulations (CAR) Part V – Airworthiness, Subparts 71 (Maintenance) and 73 (Approved Maintenance Organizations).

The European Union requirements for maintenance are contained in the regulation (EC) No 2018/1139 of the European Parliament and of the Council - Commission Regulation (EC) No 1321/2014, Annex II Part-145, as amended (EASA Part-145) and the respective EASA Acceptable Means of Compliance (AMC) and Guidance Material (GM).

TCCA and EASA have determined that the regulatory systems between EASA Part-145 and CAR Subparts 71 and 73 are sufficiently equivalent. This led to the establishment of specific regulatory requirements listed in Appendix B1 to Annex B of the Agreement. Any AMO of one Party that has been certified by a Competent Authority of that Party to perform maintenance functions shall be required to have a MAG Supplement to its manual in order to comply with the specific regulatory requirements. When it is satisfied that the MAG Supplement meets the requirements set out in Appendix B1 to Annex B of the Agreement, the respective Competent Authority shall issue an approval attesting compliance with the applicable requirements. Ratings and limitations shall not exceed that contained in its own certificate.

Under the leadership of the Joint Sectorial Committee on Maintenance, EASA and TCCA have agreed to organize, as appropriate, reciprocal participation in each other’s internal standardization or quality control system.

Section A
Competent Authority Interaction
(Not applicable to Industry)

I. General

1. Purpose

The purpose of this section of the MAG is to detail the interface procedures and activities between TCCA, the EASA and the CAs of the EU Member States required to implement Annex B of the Agreement.

2. Communications

Proposed significant revisions to the relevant laws, regulations, standards, acceptable means of compliance and guidance material which may affect the basis and the scope of this guidance should be notified in a manner consistent with Article 8 of the Agreement. Accordingly, upon notice of such changes TCCA or EASA may request a meeting to review the need for amendment to this MAG.

The list of contact points for the various technical aspects of the MAG, including communication of urgent issues is included in Appendix 1.

3. Training

In order to comply with the MAG and the requirements of Annex B to the Agreement, inspectors with oversight assignment of TCCA/EASA/EU Member CA AMOs and TCCA/EASA inspectors performing Sampling Inspection System (SIS) activity shall receive initial training (Agreement, Annexes, and MAG) and recurrent MAG training in case of changes to the MAG or in case of identified SIS implementation issues.

4. Technical Consultations, Interpretations and Resolution of Issues 

4.1 Technical Consultations

The TCCA Director of Standards and the EASA Flight Standards Director agree to consult as necessary to provide input when requested on interpretations and technical issues. The frequency of these exchanges will depend upon the number and significance of the issues to be discussed.

4.2 Interpretations/Resolution of Issues

TCCA and EASA agree to address interpretations and resolve issues through consultation or any other mutually agreed-upon means. Every effort shall be made to resolve the issues at the lowest possible level.

Issues that cannot be satisfactorily resolved between the TCCA Director of Standards and EASA Flight Standards Director on an ad hoc basis shall be added to the agenda for the next formal Joint Sectorial Committee on Maintenance (JSCM) meeting for further consideration.

Issues that cannot be resolved by the JSCM must be forwarded to the Joint Committee for resolution (the Joint Committee is a joint executive level group responsible for effective functioning of the Agreement).

For the resolution of issues involving the acceptance of sub-bases and second sites that reside outside of Canada or the EU, a case-by-case review of acceptance by the parties to the Agreement can be accomplished.

Line stations located in each other’s territory are not accepted under the Agreement (i.e. you cannot exercise the privileges received under the Agreement in the territory of the other party). EASA and TCCA may review and agree to accept the use of line stations outside of Canada and the EU on a case-by-case basis.

5. Joint Sectorial Committee on Maintenance (JSCM)

The JSCM, under the leadership of the TCCA’s Director of Standards and EASA’s Flight Standards Director shall meet at least annually to ensure the effective functioning and implementation of Annex B to the Agreement by reviewing the progress on implementation issues and propose changes to this MAG when required. Meeting attendees should include the offices responsible for the technical coordination of this guidance and additional officials of TCCA, EASA, and the CAs as needed when directly affected by the meeting agenda items. At the discretion of the joint leadership, personnel and representatives of other appropriate organizations may be invited to participate.

The host is responsible for the meeting minutes and action items that are centrally tracked.

Significant audit findings, reports and recommendations resulting from standardization and SIS activities will be submitted to the JSCM. During meetings of the JSCM, TCCA and EASA shall present its plan for SIS oversight for the next 12-month period.

The JSCM shall report to the Joint Committee the issues resulting from differences the JSCM failed to resolve and shall ensure the implementation of any decisions reached by the Joint Committee.

The JSCM may set up a Joint Sectorial Maintenance Group (JSMG) comprised of representatives from both TCCA and EASA in charge of the review of the implementation of the Agreement and propose revision of this MAG to the JSCM.

The JSCM may sponsor subgroups to address specific technical issues and make recommendations for amendment to the Agreement or revisions to the MAG.

6. Revisions

The JSCM shall review the MAG as necessary. Any revisions become effective upon approval by the JSCM and shall be implemented, as applicable, 60 days after the change has been published, unless otherwise specified.

II. Cooperation in Quality Assurance and Standardization Activities

General

In order to ensure the effective functioning and implementation of Annex B to the Agreement, continued understanding and compatibility of each other’s maintenance systems should be promoted by TCCA and EASA.

To this end, TCCA and EASA shall consult and share information on quality assurance and standardization activities and promote the participation in each other’s inspections and audits. These activities may include sampling inspections at each other’s Approved Maintenance Organizations to ensure the Competent Authority is applying the procedures set forth in this MAG. TCCA and EASA may decide to conduct these visits on a scheduled or unscheduled basis.

1. Surveillance and Standardization

1.1 Access to Reports

TCCA, EASA, and the CAs of the EU Member States will provide to each other, upon request, reports of standardization, internal quality system and surveillance with regards to Annex B of the Agreement to the extent deemed necessary to ensure effective implementation.

1.2 Involvement as Observers

TCCA and EASA have the right to participate as an observer in each other’s standardization, internal quality system and surveillance activities as a means of gaining confidence, standardization and cooperation. Their role is passive, and as part of the inspection team they follow the appropriate working procedures and protocols.

1.3 Conduct of Inspections

Requests for participating in each other’s activities must be agreed upon and coordinated through the JSCM.

1.4 Verification of Annex B Specific Regulatory Requirements 

TCCA and EASA will monitor the compliance with the terms of the Agreement, namely the Specific Regulatory Requirements contained in Appendix B1 to Annex B. The audit schedule is determined by the TCCA and EASA.

During the verification of Annex B – Specific Regulatory Requirements, the reports contained in Appendix 3 and 4 of this MAG shall be used.

The number of files to be sampled should be proportional and statistically representative in relation to the number of Approved Maintenance Organizations with an approved MAG Supplement.

2. Sampling Inspection System in EU and Canada

2.1 General

The EASA Flight Standards Directorate and the TCCA Standards Branch need to ensure that the Agreement is being implemented in accordance with its terms.

In order to accomplish this, they should establish a sampling visit schedule to conduct sampling inspections.

2.2 Objectives 

The SIS objective is to monitor the application of Annex B to the Agreement to ensure that the Annex is applied in a consistent manner.

It is also intended to assist the Competent Authority in understanding mutual obligations under the terms of the Agreement.

2.3 Mode of Operation

SIS Teams need to visit selected CAs and AMOs with EU/Canadian customers on a regular basis.

When a SIS Team perceives compliance problems with the Agreement, the MAG or the application of maintenance standards, such problems are to be reported to the host authority at the conclusion of the visit using the applicable Visit Report.

During the course of the visit, the SIS Team may have cause to raise findings and/or observations in accordance with the following:

1. Non-compliance findings with regards to Annex B – Specific Regulatory Requirements. In this case the visiting SIS Team should review the Visit Reports and request the host authority to take appropriate remedial actions in a timely manner. Findings can be raised at both the Competent Authority or visited AMO level.
2. Observations should be communicated by the SIS Team Lead to the EASA Flight Standards Directorate SIS member or the TCCA Standards SIS member, as applicable, during the visit. The host authority will ensure the necessary follow up actions are taken in relation to the observation.
3. Any evidence gathered to support a finding, or an observation should be provided to the host authority in order to support any necessary follow up actions.

2.4 SIS Team Composition

Each SIS Team should consist of two experienced maintenance surveyors/inspectors. SIS Teams may include a third maintenance surveyor/inspector as an observer.

EASA members can be selected from EASA personnel with additional personnel from CAs of EU Member States, with the team leader being always from EASA. TCCA members will be selected from the TCCA Standards Branch.

The host authority may assign personnel to accompany the SIS Team during the visit to ensure that no misunderstandings arise in respect of perceived standards and interpretation of maintenance regulations. The principal surveyor/inspector responsible for the particular organization visited should join the team for that visit in order to facilitate the on-site visit and provide background information about the organization, as required.

2.5 SIS Team Visit Program 

SIS Teams will visit CAs, TCCA Regional Offices and AMOs with EU/Canadian customers at a frequency to ensure that standards are being achieved and therefore the frequency may vary in light of experience. The Competent Authorities should determine a visit schedule and coordinate the visit with the host authority. The final dates of a specific visit should be provided to the host authority at least two (2) months in advance. The host authority is expected to make every effort to both receive and cooperate with the SIS Team.

The visiting authority will determine the SIS activity schedule using objective criteria and risk analysis. The following list is not exhaustive but may illustrate the main criteria used to select an office:

1. Offices that have large concentration of organizations with approved MAG Supplements may be used as an indication of business carried out in that area and a selection of approvals used to give a sample of that office.
2. Where the visiting authority has received a number of reports of non-compliance in relation to organizations from an office, this could indicate a higher risk and need for a visit.
3. Previous sampling inspection reports that indicate a particular office may be of concern.
4. The scope of individual approvals may be used to carry out a risk analysis to indicate where safety could be most at risk.

Additionally, a review of reported occurrences may be used as an indicator of potential problem areas. Occurrence reports may be drawn from the following areas and used to make a selection:

1. EU Member States CAs
2. Operators/Approved Maintenance Organizations within the EU
3. Operators/Approved Maintenance Organizations within Canada

2.6 SIS Procedures

SIS Teams normally visit for one week. The visiting authority must liaise with the host authority coordinators to organize the visit schedule. At the start and end of each visit the host authority shall be briefed regarding the visit.

The SIS Team should complete Visit Report Office (Appendix 3, SIS Form 10) in respect of each office visited and a Visit Report Organization (Appendix 4, SIS Form 8) in respect of each AMO visited.

A member of the host authority or office visited as applicable, should also sign the Visit Reports to indicate that it has been seen, adding any comment they wish against each finding and/or observation, and if necessary, disagree. Signature by the member of the host authority or office only means that the finding and/or observation have been seen.

The SIS Team may have cause with some organizations to raise non-compliance findings and/or observations. In this case, use Visit Report Organization (SIS Form 8) to record the non-compliance. The office must carry out the necessary follow up actions.

After each visit, responsible managers of the host authority and AMO representatives must be debriefed by the SIS Team.

2.7 Resolution of SIS Team Findings

Remedial action for any SIS Team finding reported on Visit Report Office (SIS Form 10) will be taken in a timely manner (expected 90 days).

The CA must take action on the Visit Report Organization (SIS Form 8) non-compliance findings and/or observations.

Actions taken by EASA, CAs and their regional offices, and TCCA and their regional offices may be subject to review in the JSCM for follow up and closure. Reported general observations may be discussed at a JSCM meeting to ensure standards remain compatible.

III. Technical Assistance

General

TCCA and EASA will consult each other on a case-by-case basis and make all the efforts to support each other in activities deemed to be covered by item 7 of Annex B. EASA, TCCA and where appropriate other Competent Authorities, shall provide technical evaluation assistance to each other, upon request.

Types of assistance may include, but are not limited to, the following:

1. Monitoring and reporting regarding continued compliance with the requirements described in the MAG by maintenance organizations under the jurisdiction of either Party;
2. Conduct of, and reporting on investigations; and
3. Technical evaluation.

IV. Specific Regulatory Requirements

Pursuant to the Agreement, the recognition by one Party of an aircraft AMO under the jurisdiction of the other Party shall be based upon the aircraft AMO incorporating into its relevant manual, a MAG Supplement that addresses the additional requirements stated herein.

The manual shall contain a statement of commitment signed by the current Accountable Manager/Executive confirming that the organization will comply with the manual and the MAG Supplement, and shall, at a minimum, include the information specified in the appropriate annex to this document.

The supplement shall be produced in the English language and shall be approved by the Competent Authority having primary jurisdiction over the maintenance organization.

This paragraph should explain how the release of aircraft after maintenance shall be carried out in accordance with the requirements of EASA Part-145 and the additional requirements specified in Appendix B1 of the Agreement and explained further in the MAG.

Release to service of aircraft after maintenance shall be carried out in accordance with EASA Part-145 except that paragraphs 7, 8 and 9 of this TCCA Supplement shall also be taken into account and specify the aircraft maintenance plus any repairs, modifications, Airworthiness Directives, replacement parts together with the issue of approved data used. At the completion of maintenance, the following maintenance release statement will be made in the aircraft maintenance record.

Maintenance Release in accordance with EASA Part-145.A.50/CAR 571.10:

"Certifies that except as otherwise specified, the described maintenance has been performed in accordance with the applicable airworthiness requirements and the approved MAG Supplement, and in respect to that work the aircraft is ready for release to service." or in case of Canadian operators with pre-printed release statements.

The sub-clause "except as otherwise specified" is intended for use with two types of deviation as follows:

1. The case where not all of the required maintenance was carried out as agreed by the customer. The maintenance not carried out will be listed on the release.
2. The case where the particular maintenance was only TCCA approved and not EASA approved. Example: a TCCA AD not approved by EASA.

The TCCA issued Maintenance Organisation approval number will be entered into the technical record anytime a maintenance release for an aircraft is made.

11. Reporting of Unairworthy Conditions 

This paragraph should address the procedures for the reporting of failures, malfunctions or defects that affected or was likely to affect the safety of the aircraft or aeronautical product.

When any Canadian registered aircraft or aeronautical products under the jurisdiction of TCCA have failed, malfunctioned, or became defective in such a manner as to affect or would have likely affected the safety of the aircraft, it must be reported to the Canadian customer within three (3) days of discovery. It is intended that the Canadian customer will advise Transport Canada as required by the CARs and should be reported through WSRDS Transport Canada - Continuing Airworthiness Web Information System (CAWIS) | Transport Canada - Web-based Continuing Airworthiness Information System (SWIMN).

12. Line Stations

This paragraph should explain how each EASA Part-145 line station subject to the terms of the Agreement is to be listed giving its location and the basic maintenance capability at each location. 

Line stations are accepted at locations that are identified in the relevant approval/manual and are subject to the oversight of the Competent Authority. Line stations located in Canada and line stations outside of Canada or the EU in countries where existing agreements or arrangements are in place with the Competent Authority are not accepted under the Agreement (i.e. you cannot exercise the privileges received under the Agreement in Canada or in countries where existing agreements or arrangements are in place between the Competent Authorities, unless agreed otherwise on a case-by-case basis by TCCA and EASA).

Such line stations will be subject to surveillance by the Competent Authority.

13. Safety Management System (SMS) 

A Safety Management System (SMS) is required for any CAR 573 AMO that performs and certifies maintenance on aircraft operated under Subpart 5 of Part VII (CAR 705) of the CARs.

If the AMO is performing and certifying maintenance on aircraft listed above, then they will need to establish or identify SMS procedures that meet the provisions of EASA Part-145 as amended in this section of their supplement.
