CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 Netherlands CAA has issued AD CAA-NL 2004-159 affecting Fokker F50 model aircraft. The Netherlands is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/F50/90, which will become effective on 12 May 2005.
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 Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish the legal framework governing civil aviation in Australia. It provides the basis for safety regulations and standards within the industry, ensuring the safety of air navigation and the continued airworthiness of aircraft. The Act empowers the Governor-General to make regulations under section 98, and these regulations are instrumental in maintaining and enhancing aviation safety. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, include provisions for issuing airworthiness directives (ADs), which are legislative instruments that mandate the requirements necessary to ensure the continuing airworthiness of aircraft. The Civil Aviation (Airworthiness Directives) Determination 2005, for instance, reflects Australia’s commitment to international standards by aligning with directives issued by other contracting states under the Convention on International Civil Aviation. This legislative approach ensures that Australian aviation standards are consistent with international best practices, thereby maintaining high safety standards and facilitating global cooperation in aviation.
Scope and Application
The Civil Aviation Act 1988, and its associated Civil Aviation Safety Regulations 1998, govern the issuance of airworthiness directives (ADs) within Australia, with the overarching aim of ensuring the safety of air navigation. The Act applies to entities such as the Civil Aviation Safety Authority (CASA), which is designated as Australia's national airworthiness authority, and to aircraft registered in Australia, including those designed by foreign States. The geographic reach of the Act is national, ensuring compliance with international standards set forth by the Convention on International Civil Aviation, specifically Annex 8, which delineates the responsibilities of States of Design and States of Registry regarding the continuing airworthiness of aircraft. ADs are legislative instruments issued under the authority granted to CASA by regulation 39.001 of the Civil Aviation Safety Regulations 1998, and they can be mandated in response to directives issued by the State of Design, such as the Netherlands in the case of the Fokker F50 model aircraft. These directives are not subject to public consultation or a Regulatory Impact Statement, as they are grounded in international obligations and specific safety requirements.
Key Provisions
The Civil Aviation Act 1988 and its regulations provide the framework for ensuring the safety of air navigation, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Section 98 of the Civil Aviation Act 1988 grants the Governor-General the authority to make regulations necessary for the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA can issue ADs for specific types of aircraft or aeronautical products to address safety concerns. Section 39.001(5) further clarifies that ADs are considered disallowable instruments under the Acts Interpretation Act 1901, and hence are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on the parties involved are significant. The State of Design, which is the country where the aircraft type is designed, has the primary responsibility for ensuring the continuing airworthiness of the aircraft type. This includes providing necessary information to the States of Registry, which are the countries where individual aircraft are registered. In Australia, CASA, as the national airworthiness authority, is responsible for assessing ADs issued by the State of Design and, if deemed necessary, issuing corresponding Australian ADs. This ensures that Australian-registered aircraft comply with international safety standards.
There are specific obligations for both CASA and the States of Registry. CASA must diligently assess ADs issued by the State of Design and determine if an Australian AD is necessary. If so, CASA must issue the AD, ensuring that all Australian-registered aircraft comply with the safety directives. States of Registry must develop or adopt requirements to ensure the continuing airworthiness of their registered aircraft. These requirements must align with any ADs issued by the relevant State of Design or CASA.
Failure to comply with ADs can lead to serious consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly outline specific penalties for non-compliance with ADs, but general aviation regulations and acts may provide penalties for non-compliance with airworthiness requirements. These penalties can include fines, suspension or revocation of an aircraft's certificate of airworthiness, and potential criminal charges for individuals or entities responsible for the non-compliance. The severity of the penalties can vary depending on the nature and extent of the non-compliance. It is essential for all parties involved to adhere to ADs to maintain the highest safety standards in civil aviation.
