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/BEECH 200/11 affecting Beech 200 series aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 200/11. The cancellation will become effective on 10 April 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 Acting 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 was enacted to establish a comprehensive regulatory framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations that serve the interests of air navigation safety. One such regulation, the Civil Aviation Safety Regulations 1998, under section 39.001, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This authority stems from the overarching aim to maintain and enhance aviation safety standards in alignment with international conventions, particularly Annex 8 to the Convention on International Civil Aviation, which delineates the responsibilities of States of Design and States of Registry regarding aircraft airworthiness. The Civil Aviation Act 1988 thus provides the legislative foundation for CASA to act decisively in matters of aviation safety, including the issuance and cancellation of ADs as necessitated by evolving safety concerns or the resolution of identified unsafe conditions.
Scope and Application
The Civil Aviation Act 1988 applies to all aspects of civil aviation within Australia, encompassing various entities such as aircraft operators, pilots, and aviation service providers, as well as the Civil Aviation Safety Authority (CASA), which is responsible for ensuring compliance with airworthiness standards. The Act grants CASA the authority to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which are legislative instruments designed to maintain the continuing airworthiness of aircraft. These directives apply to specific types of aircraft or aeronautical products and are intended to address safety issues and ensure that aircraft remain in a safe condition for operation. The ADs are issued in accordance with international standards set out in Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry of the aircraft. The Act’s application extends nationally, and while ADs are generally made without public consultation due to their technical nature, they are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The scope of these regulations is further managed through subordinate instruments, ensuring the effective and timely dissemination of safety information to all relevant stakeholders.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (section 39.001) together establish a framework for the regulation of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Specifically, regulation 39.001(5) of the Civil Aviation Safety Regulations 1998 classifies an AD as a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus a legislative instrument as per section 6 of the Legislative Instruments Act 2003. This regulatory mechanism ensures that ADs, which are essential for maintaining the continuing airworthiness of aircraft, are issued in accordance with the requirements set out in Annex 8 to the Convention on International Civil Aviation. Under these international standards, the State of Design is responsible for the overall airworthiness of an aircraft type, while the State of Registry (CASA, in Australia's case) is responsible for ensuring the continuing airworthiness of individual aircraft.
The obligations imposed by these provisions on CASA include the assessment and potential issuance of Australian ADs when a State of Design issues a directive for a type of aircraft registered in Australia. This ensures compliance with international standards and Australian regulatory requirements. CASA's role in this process is to evaluate the information provided by the State of Design, determine if an Australian AD is necessary, and if so, issue it to mandate the required actions for maintaining airworthiness. This systematic approach aligns with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, reinforcing the importance of international cooperation in aviation safety.
There are no explicit offences, penalties, or civil/criminal consequences detailed in the text for breaches of the ADs or their cancellation. However, the rigorous process by which ADs are issued and monitored suggests that non-compliance with these directives could lead to serious safety concerns and potential legal ramifications for aircraft operators. CASA's authority to issue and cancel ADs underscores the critical role of adherence to these regulations in ensuring the safety of air navigation. The absence of specific penalties in the text implies that broader aviation safety laws and regulations may apply to cases of non-compliance, potentially leading to enforcement actions, fines, or other penalties as prescribed by relevant legislation.
