1. Purpose

This Airworthiness Notice (AN) is issued to provide information and guidance relating to the Technical Arrangement on Aviation Maintenance between Transport Canada Civil Aviation (TCCA) and the Civil Aviation Authority Singapore (CAAS). This document provides:

1.1 Procedures for the acceptance of maintenance organizations under the terms of the Technical Arrangement;
1.2 Guidelines for Air Operators and Approved Maintenance Organizations contracting for or providing maintenance in accordance with the Technical Arrangement; and
1.3 Guidelines to maintenance organizations presently approved or accepted by either authority, on the transition to the new working arrangements.

2. Introduction

On February 7, 2003, Transport Canada Civil Aviation and the Civil Aviation Authority of Singapore, signed a Technical Arrangement – Maintenance (TA-M). The TA-M has since been re-signed as a result of changes in terminology therefore these implementation procedures have been updated to reflect the revised terminology. The TA-M continues to allow for the reciprocal acceptance of maintenance organizations qualifying under the terms of the Technical Arrangement and all other applicable articles remain in force.

3. Canadian Regulatory Requirements

Canadian Aviation Regulations (CARs) Part VII subpart 6 (CAR 706) and Standards 726 require that Canadian registered aircraft and components operated in commercial air service be maintained by an Approved Maintenance Organization (AMO) approved under CAR 573.

CAR 706 and CAR 573 include provisions for the acceptance of maintenance performed on Canadian registered aircraft and components by foreign maintenance organizations where an agreement or arrangement, such as the Canada-Singapore TA-M, is in force.

By signing the TA-M, TCCA acknowledges that maintenance organizations, approved in accordance with (SAR 145) and qualifying under the terms of this TA-M are considered equivalent to a Canadian maintenance organization approved under CAR 573.

4. Singapore Regulatory Requirements

The Singapore Airworthiness Requirements Part 145 (SAR-145) requires Singapore aircraft and aircraft components to be maintained by a maintenance organization appropriately approved in accordance with the SAR-145. The SAR-145 also contains a provision to allow the acceptance of a maintenance organization located outside Singapore.

By signing the TA-M, CAAS acknowledges that maintenance organizations, approved in accordance with CAR 573 and qualifying under the terms of this TA-M are considered equivalent to a Singapore maintenance organization approved under the SAR-145.
