AD/CL-600/112 - Main Landing Gear Torque Link Apex Pin

Overview

The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia, ensuring the safety of air navigation and other related matters. Under section 98 of the Act, the Governor-General is empowered to make regulations for the purposes of the Act, primarily to uphold the safety of air navigation. The Civil Aviation Safety Regulations 1998 further define these regulatory powers, with regulation 39.001 specifically allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003. The primary objective of these regulations and directives is to ensure the continuing airworthiness of aircraft, aligning with international obligations under the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is tasked with assessing and implementing ADs issued by the State of Design, thereby fulfilling Australia’s commitment to international safety standards.

Scope and Application

The Civil Aviation Safety Regulations 1998, under section 98 of the Civil Aviation Act 1988, empower the Governor-General to make regulations that are integral to the safety of air navigation. Regulation 39.001 of these regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, as specified in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. The ADs serve as a critical mechanism for ensuring the continuing airworthiness of aircraft, mandated by Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the ongoing airworthiness of an aircraft type and requires it to provide necessary information to States of Registry. In Australia, CASA, as the national airworthiness authority, must evaluate the information provided by the State of Design and, if deemed necessary, issue an Australian AD to enforce the requirements of the original directive. The ADs issued by CASA are therefore a direct response to international obligations and the need to maintain safety standards in line with international aviation regulations.

Key Provisions

The Civil Aviation Act 1988, through section 98, empowers the Governor-General to establish regulations that ensure the safety of air navigation. Section 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. Under subregulation 39.001(5), an AD is recognised as a disallowable instrument under the Acts Interpretation Act 1901 and, consequently, a legislative instrument as per section 6 of the Legislative Instruments Act 2003. This regulatory framework is designed to maintain and enhance the safety standards of aircraft operating in Australian airspace. In accordance with Annex 8 to the Convention on International Civil Aviation, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type. This obligation includes providing necessary information to the States of Registry to ensure the aircraft's ongoing airworthiness. As Australia is a signatory to this convention, CASA, as the national airworthiness authority, must review and, if necessary, issue Australian ADs in response to ADs issued by the State of Design. This ensures compliance with international standards and maintains safety across the aviation industry. The State of Registry, which is the country where an aircraft is registered, is tasked with ensuring the continuing airworthiness of individual aircraft. Under Annex 8, the State of Registry must establish or adopt requirements to uphold the airworthiness of aircraft within its jurisdiction. For example, when Transport Canada issues an AD affecting Bombardier CL600 series aeroplanes, CASA must assess this information and issue a corresponding Australian AD if appropriate. This ensures that Australian aircraft comply with international safety standards and maintains the safety of air navigation. There are no obligations for public consultation or the preparation of a Regulatory Impact Statement for ADs issued under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, as they are directly linked to international obligations under the Convention on International Civil Aviation. The AD issued by CASA is considered a legislative instrument and is made by the Manager, Systems and New Technologies in the Airworthiness Engineering Group in accordance with subsection 84A(2) of the Act. The Civil Aviation Safety Regulations 1998 include provisions for penalties and enforcement actions in the event of non-compliance with airworthiness directives. Under section 39.005 of the Regulations, any person who fails to comply with an airworthiness directive may be subject to civil penalties, including fines. The maximum penalty for each offence is set out in the Civil Aviation (Penalty Provisions) Regulations 1995, which prescribes a penalty of up to $19,150 for each instance of non-compliance. Additionally, non-compliance can lead to criminal charges under section 23AB of the Civil Aviation Act 1988, resulting in fines of up to $220,000 for individuals and $1,100,000 for corporations, as well as potential imprisonment. These provisions underscore the importance of adhering to airworthiness directives to ensure the safety of air navigation.
