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 USA FAA has issued AD 2004-23-02 Amendment 39-13857 affecting Beechcraft aircraft. USA is the State of Design for Beechcraft aircraft type. CASA has assessed this AD and has issued Australian AD/BEECH 90 /75, Amendment 5, which will become effective on 5 July 2007. This AD cancels and replaces the previous issue.
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 Acting 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 a comprehensive legislative framework for civil aviation in Australia, addressing the need for national safety standards and regulatory oversight. Under this Act, the Governor-General has the authority to make regulations, including the issuance of airworthiness directives (ADs), to ensure the safety of air navigation. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, allowing the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. The objective of these regulations is to align with international standards, particularly those set by the International Civil Aviation Organization (ICAO), and to mandate continuing airworthiness of aircraft registered in Australia. This approach ensures that Australian aviation safety standards are consistent with global practices, thereby protecting the public and maintaining the integrity of international air travel.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) which are legislative instruments used to mandate specific safety requirements for aircraft types registered in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue such directives for types of aircraft or aeronautical products. This authority extends to ensuring the continuing airworthiness of aircraft registered in Australia in accordance with international obligations under the Convention on International Civil Aviation, particularly through Annex 8, which places responsibility for type airworthiness on the State of Design and mandates the State of Registry to implement necessary measures. The ADs serve as a mechanism for states to communicate safety-critical information. Given the international nature of the aviation industry, CASA is tasked with assessing and, where necessary, issuing Australian ADs in response to directives issued by the aircraft's State of Design. This process ensures that Australian registered aircraft meet the international safety standards set by the Convention on International Civil Aviation, thereby fulfilling Australia's commitments under the convention.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, particularly section 98 and regulation 39.001, allow the Governor-General to make regulations for air navigation safety and mandate the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Regulation 39.001(5) stipulates that ADs are legislative instruments, which means they carry the weight of law. This regulatory framework ensures that ADs, which are essential for maintaining the continuing airworthiness of aircraft, are issued under the oversight of the State of Design and adopted by the State of Registry, in this case, Australia.
The Civil Aviation Safety Regulations 1998 impose specific obligations on CASA and other entities. CASA, as the national airworthiness authority, must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to ensure compliance with safety standards. The State of Registry, in this context, Australia, must ensure that its aircraft meet the continuing airworthiness requirements set forth by the State of Design. This involves adopting the necessary measures and ensuring that all relevant parties are informed of and comply with the ADs. The responsibility of maintaining the continuing airworthiness of individual aircraft falls on the State of Registry, which must develop or adopt the necessary requirements to fulfil this obligation.
The legislation also delineates the consequences of non-compliance with ADs. While the specific offences, penalties, or consequences for breaching ADs are not detailed in the provided text, it is clear that failure to comply with ADs could result in serious ramifications. In a regulatory context such as civil aviation, non-compliance can have severe safety implications and could potentially lead to both civil and criminal penalties. Given the critical nature of airworthiness directives, regulatory authorities such as CASA are likely to enforce compliance rigorously to uphold the highest safety standards. Although the exact penalties are not specified in the provided excerpt, the seriousness of potential breaches is underscored by the mandatory nature of ADs and the stringent regulatory oversight they entail.
