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 400/16 affecting Cessna 400 series aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 25 September 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to provide a framework for the regulation of civil aviation in Australia, was introduced to ensure the safety and efficiency of air navigation, including the regulation of aircraft and aeronautical products. This legislation empowers the Governor-General to make regulations that align with the Act’s objectives, particularly those related to the safety of air navigation. Under the authority granted by section 98 of the Civil Aviation Act, the Civil Aviation Safety Regulations 1998 were established, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various kinds of aircraft and aeronautical products. These directives serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft, as mandated by international standards set forth in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, plays a pivotal role in assessing international ADs and issuing corresponding directives to ensure compliance with safety standards within Australia.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia, which are instruments that mandate the maintenance, repair, or replacement of aircraft components to ensure continuing airworthiness. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, thereby extending the scope of these regulations to any aircraft registered in Australia and any aeronautical products used within Australian jurisdiction. Such directives are designed to comply with the requirements of Annex 8 to the Convention on International Civil Aviation, which places the responsibility of ensuring continuing airworthiness on the State of Registry, which in Australia is CASA. These ADs are legislative instruments as defined under section 46A of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The application of these regulations is national, affecting all aircraft and aeronautical products registered in Australia, and are subject to the international obligations under the Convention on International Civil Aviation. There are no specific exclusions mentioned in the text, but the application of ADs is contingent upon the assessment by CASA of the information provided by the State of Design, and the necessity to ensure the safety of air navigation as per section 98 of the Civil Aviation Act 1988. The authority to issue and cancel ADs extends through subordinate instruments as per the legislative provisions.
Key Provisions
The Civil Aviation Act 1988, through section 98, grants the Governor-General the authority to create regulations that support the Act, particularly focusing on the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory power is essential for maintaining the safety standards of the aviation industry. Subregulation 39.001(5) clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and as such, it is considered a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
Under these provisions, the obligations for CASA and other entities are significant. CASA must ensure that any AD issued by the State of Design, which has the responsibility for the continuing airworthiness of an aircraft type, is assessed and, if deemed appropriate, translated into an Australian AD. This obligation ensures that the requirements for maintaining the airworthiness of aircraft registered in Australia are effectively communicated and enforced. The State of Registry, which is the State responsible for the individual aircraft, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. These requirements must align with the ADs issued by the State of Design.
The Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 establish clear consequences for non-compliance with ADs. While the specific offences, penalties, or civil/criminal consequences for breach are not detailed in the provided text, it is known that ADs are crucial for maintaining safety standards. Non-compliance with these directives could lead to significant safety risks, potentially resulting in severe civil or criminal penalties. The seriousness of these potential consequences underscores the importance of adhering to ADs and ensuring the airworthiness of aircraft is maintained.
Additionally, the process of issuing and cancelling ADs is closely tied to international obligations. For example, under Annex 8 to the Convention on International Civil Aviation, the State of Design must provide necessary information to ensure the continuing airworthiness of aircraft types, which may result in the issuance or cancellation of ADs. The text notes that the AD/CESSNA 400/16, which affected Cessna 400 series aircraft, was cancelled by CASA as the unsafe condition it was addressing no longer existed. The cancellation of such an AD without public consultation is permissible under the Convention and reflects the importance of international cooperation in maintaining aviation safety standards.
