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/GOV/9 affecting McCauley Governors incorporating Part No. A-1635-105 Socket Head Cap Screws. CASA has assessed this AD and as a result has cancelled Australian AD/GOV/9. The cancellation will become effective on 9 April 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 comprehensive legal framework for civil aviation in Australia, addressing the need for safety regulations and oversight in the aviation industry. One of the key provisions of the Act is the authority it grants to the Governor-General to make regulations for the purposes of the Act, particularly in the interests of the safety of air navigation. Under this authority, the Civil Aviation Safety Regulations 1998 were created, which include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs serve as a critical mechanism for ensuring the continuing airworthiness of aircraft types, in line with the responsibilities of the State of Design under Annex 8 to the Convention on International Civil Aviation. The enactment of the Civil Aviation Act 1988 and the subsequent regulations were pivotal in establishing a robust regulatory environment to safeguard air navigation and aircraft safety in Australia.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations for the purposes of the Act, with a focus on the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments, and in line with international standards, they are crucial for maintaining the continuing airworthiness of aircraft types. The State of Design, typically the country where the aircraft is designed, is responsible for providing necessary information to ensure airworthiness, while the State of Registry, in this case Australia, is responsible for the continuing airworthiness of individual aircraft registered within its jurisdiction. CASA's role includes assessing information from the State of Design and issuing Australian ADs as necessary to comply with international obligations under the Convention on International Civil Aviation.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998, as relevant to airworthiness directives, are sections 39.001 and 39.001(5). Section 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 39.001(5) clarifies that these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, they are legislative instruments according to section 6 of the Legislative Instruments Act 2003. The issuance of these directives is a critical tool in ensuring the continuing airworthiness of aircraft registered in Australia, and they reflect the international standards set forth in Annex 8 to the Convention on International Civil Aviation.
Under the Civil Aviation Safety Regulations 1998, CASA has the obligation to assess any ADs issued by the State of Design that pertain to aircraft on the Australian Register. This process includes the potential issuance of Australian ADs, which mandate specific requirements to ensure the safety and airworthiness of the aircraft. The State of Registry, in this case CASA, is responsible for implementing these requirements to maintain the airworthiness of the aircraft registered within Australia. This obligation is further supported by the international responsibility of the State of Design to provide necessary information to the State of Registry to support the continuing airworthiness of the aircraft type.
Failure to comply with the airworthiness directives when they are issued can result in significant consequences. While the specific offences and penalties for non-compliance with ADs are not detailed in the text, it is reasonable to infer that such non-compliance could lead to severe civil or criminal penalties. These could include fines, imprisonment, or other sanctions as deemed appropriate by the courts, reflecting the seriousness of ensuring airworthiness to maintain the safety of air navigation. The specific details of such penalties would be governed by the broader provisions of the Civil Aviation Act 1988 and related legislation.
