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 French DGAC has issued AD 84-134-29(B) affecting SA 315 model helicopters. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/SA 315/11, which will become effective on 23 November 2006.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, with a focus on ensuring the safety and efficiency of air navigation. The Act grants the Governor-General the authority to make regulations necessary for the purposes of the Act and in the interests of the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of this Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These directives are crucial for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry as per Annex 8 to the Convention on International Civil Aviation. This legislation ensures that Australia complies with international standards and obligations, while CASA acts as the national airworthiness authority, issuing Australian ADs in response to ADs issued by the relevant State of Design.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations apply to the continuing airworthiness of aircraft and aeronautical products, with CASA, as Australia's national airworthiness authority, responsible for ensuring that all aircraft registered in Australia meet required safety standards. The Act applies to any aircraft registered in Australia, as well as any aeronautical products used in Australian aviation. Geographically, the Act's application extends to the entire Commonwealth of Australia, encompassing all states and territories. The issuance of ADs is guided by Annex 8 to the Convention on International Civil Aviation, which delineates the responsibilities of the State of Design and the State of Registry in ensuring the continuing airworthiness of aircraft types. Notably, ADs are considered legislative instruments under the Legislative Instruments Act 2003, subject to disallowance under the Acts Interpretation Act 1901. While ADs are mandated by international obligations, specific ADs, such as AD/SA 315/11 in response to a French AD, do not require public consultation or a Regulatory Impact Statement as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legislative framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Specifically, section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. This regulatory power is exercised under subregulation 39.001(5), which classifies ADs as disallowable instruments according to section 46A of the Acts Interpretation Act 1901, and as legislative instruments under section 6 of the Legislative Instruments Act 2003.
Under these provisions, the State of Design, which in this case is France for the SA 315 model helicopters, bears the overall responsibility for ensuring the continuing airworthiness of an aircraft type. This responsibility includes providing necessary information to the States of Registry, which are the countries that register individual aircraft. In Australia, CASA, as the national airworthiness authority, is responsible for assessing information from the State of Design and, if appropriate, issuing an Australian AD to enforce the requirements of the original directive. This process ensures that Australian aircraft comply with international standards and maintain their airworthiness.
Compliance with these ADs imposes specific obligations on the parties governed by the regulations. Aircraft operators and owners must adhere to the requirements outlined in the ADs, which may include inspections, repairs, or modifications to the aircraft to address safety issues identified by CASA. Failure to comply with an AD can result in serious safety risks, including the potential grounding of the affected aircraft until the required actions are taken. CASA monitors compliance through regular inspections and audits, and may take enforcement action against operators who fail to adhere to the directives.
The Civil Aviation Safety Regulations 1998 also detail the consequences of non-compliance with ADs. While the specific penalties for breaching ADs are not outlined in the provided text, regulatory non-compliance generally results in civil or criminal penalties under Australian law. In civil cases, penalties may include fines and other administrative sanctions, while criminal breaches could lead to imprisonment or substantial fines. The severity of these penalties reflects the importance of adhering to ADs in maintaining the safety of air navigation.
