CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
The Civil Aviation Safety Authority or its predecessors issued AD/HU 369/50 affecting McDonnell Douglas (Hughes) 369 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 369/50. The cancellation will become effective on 4 June 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, focusing on safety and efficiency within the aviation industry. This Act empowers the Governor-General to create regulations that ensure the safety of air navigation, including the issuance of airworthiness directives (ADs) as stipulated under section 98. These directives are critical for maintaining the continuing airworthiness of aircraft, ensuring that they meet safety standards set by the Civil Aviation Safety Regulations 1998. The Civil Aviation Safety Authority (CASA) plays a pivotal role in issuing these directives, which are legislative instruments subject to disallowance and oversight under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003 respectively. The objective of this legislation is to align Australian aviation safety practices with international standards, particularly those outlined in Annex 8 of the Convention on International Civil Aviation, thereby facilitating consistent safety protocols across different jurisdictions.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) in Australia, with the overarching aim of ensuring the safety of air navigation. Under this legislative structure, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs concerning specific types of aircraft or aeronautical products, as stipulated in regulation 39.001. These ADs are considered legislative instruments, subject to disallowance and the Legislative Instruments Act 2003. The scope of the ADs is aligned with the international obligations under Annex 8 to the Convention on International Civil Aviation, which places the responsibility for the continuing airworthiness of aircraft types with the State of Design, while the State of Registry, in this case CASA, is tasked with ensuring the ongoing airworthiness of individual aircraft within Australia. The regulatory process involves CASA assessing information from the State of Design and, when necessary, issuing corresponding Australian ADs. The cessation of Australian AD/HU 369/50 for McDonnell Douglas (Hughes) 369 series Helicopters exemplifies this process, with the cancellation effective from 4 June 2009, reflecting Australia's adherence to international civil aviation standards.
Key Provisions
The Civil Aviation Act 1988, as amended, grants the Governor-General the authority to establish regulations under section 98, with a focus on ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs, as delineated 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. Such directives serve as a vital mechanism for maintaining the continuing airworthiness of aircraft types, as stipulated under Annex 8 of the Convention on International Civil Aviation, where the State of Design bears the responsibility for ensuring that the type of aircraft remains airworthy and must provide necessary information to the States of Registry.
The obligations under this legislative framework require the State of Design to take the lead in ensuring the continuing airworthiness of an aircraft type, thereby providing all necessary information to the States of Registry to maintain airworthiness standards. Conversely, the State of Registry must develop or adopt requisite measures to ensure the ongoing airworthiness of individual aircraft. In the Australian context, CASA, as the national airworthiness authority, is mandated to assess information provided by the State of Design and, if deemed necessary, issue an Australian AD to enforce the requirements stipulated by the State of Design. This ensures that Australian aircraft remain compliant with international safety standards.
Failure to comply with the airworthiness directives could result in serious consequences. The Civil Aviation Act 1988 imposes obligations on aircraft operators and owners to adhere to the ADs, ensuring the safety and airworthiness of their aircraft. Non-compliance with these directives could lead to severe civil or criminal penalties. While the specific penalties are not detailed in the provided text, it is clear that breaching the ADs could result in significant legal repercussions, potentially including fines and other enforcement actions by CASA. The gravity of these consequences underscores the importance of strict adherence to the airworthiness directives to maintain the highest standards of aviation safety.
