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 207/8 affecting all Cessna 207 series model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 207/8. 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, Airframe and Structures, 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 comprehensive legal framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation and the continuing airworthiness of aircraft. Under this Act, the Governor-General is empowered to make regulations that contribute to the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under this Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs serve as a means of ensuring that aircraft maintain their airworthiness and comply with safety standards. The ADs are legislative instruments and must comply with the requirements set out in the Legislative Instruments Act 2003. The Civil Aviation Act 1988 and the associated regulations are instrumental in aligning Australia's aviation safety practices with international standards, particularly those set by the International Civil Aviation Organization (ICAO).
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of airworthiness directives (ADs) in Australia. Pursuant to 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. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products, thereby ensuring the continuing airworthiness of aircraft registered in Australia. These ADs are legislative instruments subject to disallowance under section 46A of the Acts Interpretation Act 1901. This regulatory framework extends to all aircraft registered in Australia and is administered by CASA, which acts in accordance with the obligations under Annex 8 of the Convention on International Civil Aviation. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, and the State of Registry, in this case CASA, must ensure that appropriate measures are implemented to maintain airworthiness standards. The issuance, assessment, and enforcement of ADs are integral to these responsibilities, as illustrated by the recent cancellation of AD/CESSNA 207/8 for all Cessna 207 series model aeroplanes, reflecting the dynamic nature of airworthiness management in Australia.
Key Provisions
The key provisions of the Civil Aviation Safety Regulations 1998, as related to the issuing of airworthiness directives (ADs) under section 98 of the Civil Aviation Act 1988, are found in regulation 39.001. This regulation allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products (39.001). These ADs are considered legislative instruments as they are disallowable instruments under section 46A of the Acts Interpretation Act 1901 and thus subject to the Legislative Instruments Act 2003 (39.001(5)). Annex 8 to the Convention on International Civil Aviation further underscores the State of Design's responsibility for the continuing airworthiness of an aircraft type, necessitating the provision of necessary information to States of Registry.
The obligations imposed by these regulations primarily concern the State of Design and the State of Registry. The State of Design must ensure that any information necessary for the continuing airworthiness of an aircraft type is made available to the States of Registry. The State of Registry, in turn, has the responsibility of developing or adopting requirements to maintain the continuing airworthiness of aircraft registered within its territory. In the context of Australia, CASA is tasked with assessing information from the State of Design and, if deemed appropriate, issuing Australian ADs to enforce the requirements of the State of Design on aircraft registered in Australia.
The consequences for non-compliance with these regulations are significant. While specific offences under the Civil Aviation Safety Regulations 1998 are not detailed in the provided text, the overarching framework of the Civil Aviation Act 1988 includes provisions for both criminal and civil penalties. For instance, serious breaches may result in fines and imprisonment, as stipulated by various sections of the Act. Furthermore, CASA retains the authority to take enforcement actions, such as grounding non-compliant aircraft or imposing operational restrictions.
Given the international nature of aviation, adherence to these ADs and regulations is crucial for ensuring safety and compliance across borders. The Civil Aviation Safety Authority's cancellation of AD/CESSNA 207/8, due to the resolution of an unsafe condition, exemplifies the dynamic nature of airworthiness directives and the need for ongoing vigilance and compliance from all stakeholders involved in the aviation industry.
