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/CESSNA 337/23 affecting Cessna 337 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 337/23. The cancellation will become effective on 8 May 2008. 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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, aims to regulate civil aviation and ensure the safety of air navigation within the country. To address the need for maintaining the continuing airworthiness of aircraft, the Civil Aviation (Airworthiness) Regulations 1998 were introduced under section 98 of the Act, empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives. These directives are legislative instruments that mandate safety requirements for specific aircraft types or aeronautical products. The policy objective of these regulations is to align with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, must respond to directives from the State of Design by issuing corresponding Australian directives if necessary, ensuring compliance with both national and international safety standards.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, mandates the issuance of airworthiness directives (ADs) to ensure the safety of air navigation, as outlined in regulation 39.001. These directives apply to specific types of aircraft or aeronautical products and are issued by the Civil Aviation Safety Authority (CASA), which acts on behalf of the Australian government as the national airworthiness authority. The application of these ADs is guided by Annex 8 to the Convention on International Civil Aviation, which places responsibility for the continuing airworthiness of an aircraft with the State of Design, while the State of Registry, in this case Australia, must implement the necessary requirements to maintain airworthiness. ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and subject to the provisions of the Legislative Instruments Act 2003. The scope of these regulations extends nationally, as CASA's actions are governed by international standards and obligations, ensuring that all aircraft registered in Australia meet the required safety standards.
Key Provisions
The Civil Aviation Act 1988 (section 98) allows the Governor-General to establish regulations that promote air navigation safety. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft types or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. Furthermore, under subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, an AD is deemed a disallowable instrument in accordance with section 46A of the Acts Interpretation Act 1901, and is therefore recognised as a legislative instrument under section 6 of the Legislative Instruments Act 2003.
Entities and parties governed by the Act, such as CASA, are required to issue ADs based on the continuing airworthiness of aircraft types and aeronautical products. As per Annex 8 to the Convention on International Civil Aviation, the State of Design bears the responsibility for ensuring the continuing airworthiness of an aircraft type and must provide necessary information to the appropriate States of Registry. Consequently, the State of Registry must establish or adopt requirements to maintain the continuing airworthiness of aircraft. When a State of Design issues an AD, CASA must assess the information and, if appropriate, issue an Australian AD to enforce the State of Design's requirements.
Failure to comply with ADs can lead to serious consequences, including potential safety hazards and legal repercussions. Although the specific offences, penalties, or consequences for non-compliance with ADs are not outlined in the Civil Aviation Act 1988, it is evident that such non-compliance can result in safety risks and legal action. In some cases, non-compliance with ADs may lead to fines, imprisonment, or both, depending on the severity of the breach and the applicable aviation regulations. Additionally, aircraft operators may face penalties such as suspension or revocation of their airworthiness certificates, which can result in grounded aircraft and financial losses.
In summary, the Civil Aviation Act 1988 and its associated regulations empower CASA to issue ADs to maintain air navigation safety. Entities and parties governed by the Act must adhere to these ADs to ensure the continuing airworthiness of aircraft. Non-compliance with ADs can result in safety risks and legal consequences, including fines, imprisonment, and suspension or revocation of airworthiness certificates.
