Technical arrangement on maintenance - United Kingdom

Technical arrangement on maintenance between the United Kingdom Civil Aviation Authority and Transport Canada Civil Aviation

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

CONSIDERING the “Technical Arrangement on Airworthiness between the Aviation Regulation Directorate, Transport Canada, and the Safety Services Group, United Kingdom Civil Aviation Authority” (the TA-A) signed on April 27, 1987, 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 organisations 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).

Table of contents

1. Definitions

For the purposes of this TA-M:

Aircraft Certification Authority (ACA) means the authorization issued by the Approved Maintenance Organisation to those individuals who have been assigned maintenance release privileges on an aircraft, in accordance with the procedures and conditions specified in the company’s Maintenance Policy Manual or Maintenance Organisation Exposition (MOE).

“Aircraft” means any machine that can derive support in the atmosphere from the reactions of the air other than reactions of the air against the Earth’s surface.

“Approved Data” includes type certificates, supplemental type certificates, part design approvals, Canadian technical standard order (CAN-TSO) design approvals or repair design approvals as described in the applicable Technical Implementation Procedures.

“Approved Maintenance Organisation (AMO)” means a natural person or a legal person entitled to maintain any aircraft or component for which it is approved.

“CAR” means Canadian Aviation Regulations.

“Civil aeronautical product” means any civil aircraft, or aircraft engine, propeller, appliance, part or component to be installed thereon.

“Component Rated AMO” means an AMO of which scope of ratings and limitations approved by UK CAA or TCCA that includes civil aeronautical products other than the aircraft category.

“Maintenance” means the performance of inspection, overhaul, repair, preservation, and the replacement of parts, materials, appliances, or components of a product to assure the continued airworthiness of that product, including the performance of approved modifications.

“Monitoring” means the periodic surveillance by an Authority to determine continuing compliance with the appropriate standards.

“Overseeing Authority” means the civil aviation authority having jurisdiction over a maintenance organisation performing maintenance functions covered by this TA-M.

“Part 145” means an approval issued under Annex II to Regulation (EU) 1321/2014 for the continuing airworthiness of aircraft and aeronautical products, parts and appliances, and on the approval of organisations and personnel involved in these tasks (Regulation 1321/2014) as applicable in UK law pursuant to the UK’s European Union (Withdrawal) Act 2018.

“Principal Place of Business” means the head office or registered office of the undertaking within which the principal financial functions and operational control of the activities referred to in Regulation 1321/2014 are exercised.

“Responsible Authority” means the civil aviation authority having legal responsibility for regulating and controlling civil aeronautical products.

“SCA” means shop certification authority. A Canadian AMO will issue this authority to those individuals who have been assigned maintenance release privileges on civil aeronautical products intended for installation on aircraft in accordance with the procedures and conditions found within the company’s Maintenance Policy Manual. This is synonymous with the term component certification authorization issued by a UK CAA AMO.

2. Objective

  • (a) 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.
  • (b) 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

  • (a) In order to avoid duplication of inspections and evaluations to the maximum extent, each Authority may give the same validity to:
    • (i) the other Authority’s inspection and evaluation findings for the approval of maintenance organisations as to its own inspection and evaluation findings; and
    • (ii) the other Authority’s system for the release to service of aircraft after maintenance as to its own release system.

4. Sub-sections

  • (a) The Authorities understand that this TA-M is sub-divided into three Sections:
    • (i) Section A: outlines the authority interaction between UK CAA and TCCA;
    • (ii) Section B: outlines the steps necessary for a Part 145 AMO with its principle place of business located in UK to maintain aircraft under the regulatory control of TCCA;
    • (iii) Section C: outlines the steps necessary for a TCCA Canadian Aviation Regulation CAR 573 AMO located in Canada to maintain aircraft under the regulatory control of UK CAA.

Section A: Authority interaction

1. Bilateral arrangement for the promotion of aviation safety

The Authorities recommend that maintenance organisations and personnel maintaining aircraft under their respective jurisdictions be familiar with the TA-A and follow this TA-M.

2. Authorization

Unless they jointly decide otherwise, in writing, the Authorities will not issue approvals to maintenance organisations in the territory of the other Authority, except as provided in this TA-M.

3. Communication and information

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