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 United States FAA has issued AD 2005-24-13 affecting Bombardier Learjet 45 aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/LJ45/8, which will become effective on 20 December 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 Acting Manager, New Technologies and Systems, 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, enacted by the Australian Parliament, serves to regulate the safety and efficiency of civil aviation within Australia, addressing the need for comprehensive oversight to ensure the safety of air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were established, empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These directives are critical for maintaining the continuing airworthiness of aircraft, aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The issuance of ADs is a response to Australia’s obligations under this convention and follows assessments by CASA to ensure compliance with international safety requirements. This regulatory framework ensures that Australian aircraft meet necessary safety standards, with CASA acting as the national airworthiness authority to mandate these requirements effectively.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, ensuring compliance with safety regulations. These ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and are created in accordance with section 6 of the Legislative Instruments Act 2003. The issuing of ADs aligns with the State of Design's responsibility under Annex 8 of the Convention on International Civil Aviation, which mandates that the designing state must provide necessary information for continuing airworthiness to relevant states of registry. CASA, acting as Australia's national airworthiness authority, evaluates information from states of design and issues corresponding Australian ADs if necessary. For instance, following the United States Federal Aviation Administration's issuance of AD 2005-24-13 for Bombardier Learjet 45 aircraft, CASA assessed the directive and issued AD/LJ45/8, effective from 20 December 2005. This process reflects Australia's commitment to international aviation safety standards without requiring public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The key provisions of the Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, outline the framework for the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Section 98 of the Act empowers the Governor-General to create regulations that serve the safety of air navigation, and regulation 39.001 of the Regulations enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby categorising them as legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions on CASA and the State of Registry are significant. CASA, as Australia’s national airworthiness authority, must assess information provided by the State of Design regarding ADs. If deemed necessary, CASA must issue corresponding Australian ADs to enforce the requirements of the State of Design. The State of Registry is also responsible for ensuring the continuing airworthiness of individual aircraft, developing or adopting necessary requirements to meet this obligation. These provisions underscore the importance of international collaboration in maintaining airworthiness standards, as outlined in Annex 8 to the Convention on International Civil Aviation.
In terms of compliance and enforcement, breaches of ADs may lead to significant consequences. Although specific offences and penalties are not detailed within this excerpt, the overarching legislation implies that non-compliance with ADs could result in civil or criminal penalties. Given that ADs are legally binding and necessary for safety, failure to adhere to them can potentially lead to severe repercussions, including but not limited to fines or imprisonment, depending on the nature and severity of the breach. The legal framework ensures that these directives are strictly enforced to maintain the highest safety standards in air navigation.
