The United Kingdom Civil Aviation Authority (UK CAA) and Transport Canada Civil Aviation (TCCA), (collectively, the Authorities),

Considering the “Working Arrangement between the Civil Aviation Directorate of the Department of Transport of Canada and the Civil Aviation Authority of the United Kingdom of Great Britain and Northern Ireland for the promotion of aviation safety” (the “Working Arrangement”) that came into operation January 1, 2021, which recognized the need for a temporary administrative solution to ensure the continuity of aviation safety activities between TCCA and CAA until such a time as a similar Bilateral Agreement on Civil Aviation Safety between Canada and the United Kingdom has entered into force and which provides for the basis to develop a technical arrangement with regard to aircraft maintenance,

Considering that they have conducted technical assessments and developed an understanding of each other’s regulations, standards, and systems with regards to airworthiness approvals and maintenance certification of civil aeronautical products, approval and monitoring of maintenance organizations and approval of persons,

Considering that their respective national law, procedures, and systems for the performance of maintenance are sufficiently comparable to permit the mutual acceptance of maintenance certification subject to the procedures described in this Technical Arrangement for Maintenance (TA-M).

  • (1) The objective of this TA-M is to outline the terms and conditions for the reciprocal acceptance and recognition by the Authorities of each other’s aviation safety program with regards to the performance and certification of aircraft maintenance.

  • (2) Nothing in this TA-M is intended to create a binding legal agreement, or to supersede, prejudice or otherwise derogate from the respective laws and regulations, administrative practices, or procedures, or administrative or adjudicative decision-making of the Authorities. This TA-M will not affect the rights and commitments of the Authorities under other international instruments.

3. Recognition of validity

  • (1) In order to avoid duplication of inspections and evaluations to the maximum extent, each Authority may give the same validity to:

    • (a) the other Authority’s inspection and evaluation of findings for the approval of maintenance organisations as to its own inspection and evaluation findings; and

    • (b) the other Authority’s system for the release to service of aircraft after maintenance as to its own release system.

4. Sections

  • (1) The Authorities understand that this TA-M is sub-divided into three Sections:

    • (a) Section A: outlines the authority interaction between UK CAA and TCCA;

    • (b) Section B: outlines the steps necessary for a Part 145 AMO with its principal place of business located in the UK to maintain aircraft under the regulatory control of TCCA; and

    • (c) Section C: outlines the steps necessary for a Canadian Aviation Regulation (CAR) 573 AMO with its principal place of business in Canada to maintain aircraft under the regulatory control of the UK CAA.

Such organisations’ facilities, whether located inside or outside of Canada and the UK will be subject to monitoring by the Overseeing Authority;

    • (b) An AMO approved by their Overseeing Authority will not perform maintenance or sign a maintenance release within the territorial boundaries of the other Authority’s country, except when the AMO is approved by the same Authority as the State of Registry. This includes a maintenance release on a civil aeronautical product removed, maintained and re-installed on the same registered aircraft;

    • (c) The territorial boundaries mentioned in 4(b) means, in relation to Canada, Canadian territory inclusive of its provinces and territories, and in relation to the UK, the territory of Great Britain and Northern Ireland; and

    • (d) The certification of maintenance performed on civil aeronautical products, other than complete aircraft, will be carried out in accordance with the requirements of Part 145 and CAR 573, which are considered equivalent.
