Overview

The Civil Aviation Regulations 1998 (the Regulations), administered by the Civil Aviation Safety Authority (CASA), are designed to ensure the safety and efficiency of civil aviation in Australia. One of the key components of these regulations is the scheduling of airworthiness directives, which are legally enforceable requirements aimed at addressing specific safety issues in aircraft. The particular legislative instrument F2006B08627 pertains to the Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes, introducing an airworthiness directive aimed at rectifying an issue with the horizontal stabiliser pitch trim actuator. This directive was introduced to address a potential safety risk where the pitch trim actuator's motor drive gear pinions might become loose, leading to damage of internal control wiring. The aim is to ensure that this compliance is met before the issuance of an Australian Certificate of Airworthiness, thereby maintaining high safety standards in civil aviation. The instrument references a related Canadian Department of Transport directive (AD CF-82-05) and a Canadair Service Bulletin (SB No. A600-0084) as foundational documents guiding the implementation of this safety measure.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, pertains to airworthiness directives issued by the Civil Aviation Safety Authority (CASA). This particular legislation applies to Bombardier (Canadair) CL-600 (Challenger) series aeroplanes, focusing on the modification of horizontal stabiliser pitch trim actuators as outlined in the requirement document, namely Canadair Challenger Alert SB No. A600-0084. This directive is influenced by the Canadian Department of Transport AD CF-82-05, which addresses similar safety concerns. Compliance with these regulations is mandatory and must be met before the issue of an Australian Certificate of Airworthiness. The directive is applicable to the identified pitch trim actuators and aims to prevent potential damage to internal control wiring, which could arise from loose motor drive gear pinions. The scope of this legislation extends across the Commonwealth of Australia, ensuring that all relevant aircraft operators and maintenance entities comply with these safety standards. No specific exclusions or exemptions are detailed in the regulations, implying a broad application across the aviation industry within the jurisdiction.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, Part 39, in relation to the Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes, specifically address the modification of the horizontal stabiliser pitch trim actuator. Section 39-105 of the regulations outlines the mandatory requirements for the modification of pitch trim actuators as listed in the requirement document, Canadair Challenger Alert SB No. A600-0084, which references the Canadian Department of Transport AD CF-82-05. The compliance requirement states that any modifications to the pitch trim actuators must be completed before the issue of an Australian Certificate of Airworthiness. The Act imposes several obligations and requirements on the parties or entities it governs. Firstly, it mandates that the horizontal stabiliser pitch trim actuators of Bombardier (Canadair) CL-600 (Challenger) Series Aeroplanes must be modified to prevent the suspected issue of loose motor drive gear pinions, which could lead to damage of the internal control wiring. This modification is to be carried out in accordance with the specified requirement document and Canadian Department of Transport directive. Additionally, the modifications must be completed prior to the issuance of an Australian Certificate of Airworthiness, ensuring that the aircraft meets all safety standards before it can be legally operated. In terms of consequences for non-compliance, the Act does not explicitly detail specific offences, penalties, or civil/criminal consequences for breaches within the provided text. However, failure to comply with the mandatory modification requirements could potentially result in the non-issuance of an Australian Certificate of Airworthiness, which is a critical document for the legal operation of the aircraft in Australia. This in turn could lead to legal and operational issues for the aircraft owner or operator, potentially including the grounding of the aircraft until the required modifications are completed and verified by the relevant authorities.
