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 German LBA has issued AD 2001-261 affecting Dornier 328 model aircraft. Germany is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DO 328/42, which will become effective on 16 March 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, enacted by the Australian Parliament, aims to ensure the safety and efficiency of air navigation. This Act provides the framework for regulating civil aviation in Australia, including the issuance of airworthiness directives (ADs) to maintain the airworthiness of aircraft. The Civil Aviation Safety Regulations 1998 further detail the procedures for ADs, allowing the Civil Aviation Safety Authority (CASA) to issue these directives for certain types of aircraft and aeronautical products. The policy objective is to align Australia's aviation safety practices with international standards as outlined in the Convention on International Civil Aviation, ensuring that Australian-registered aircraft meet the required safety standards set by the aircraft's State of Design. The issuance of ADs is a critical tool in maintaining the safety of air navigation, as it mandates specific actions to address potential safety issues in aircraft or aeronautical products.
Scope and Application
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments that fall under the authority of the Civil Aviation Act 1988, aimed at ensuring the safety of air navigation. The application of these directives extends to any aircraft registered in Australia, and they are intended to mandate the requirements set by the aircraft's State of Design. This process aligns with international obligations under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, must assess the information provided by the State of Design and, if necessary, issue an Australian AD to enforce these requirements. The issuance of ADs does not require public consultation and is determined by the Manager, Airframes within CASA, ensuring compliance with both national and international aviation safety standards.
Key Provisions
The Civil Aviation Safety Regulations 1998, particularly under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are intended to ensure that aircraft maintain a state of airworthiness, which is crucial for safety in air navigation (section 98 of the Civil Aviation Act 1988). Under subregulation 39.001(5), ADs are classified as disallowable instruments, which means they can be annulled by a resolution of either House of the Parliament. This classification also designates ADs as legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations primarily rest on CASA, as Australia’s national airworthiness authority, to assess and, if necessary, issue Australian ADs that align with the requirements set forth by the State of Design. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type and must provide all necessary information to ensure this airworthiness. Meanwhile, the State of Registry, which in the case of Australian aircraft is CASA, is obligated to develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. When an AD is issued by the State of Design, CASA must review and, if appropriate, issue a corresponding Australian AD to mandate these requirements.
Failure to comply with airworthiness directives can result in severe consequences, both civil and criminal. Civil penalties may include fines, while criminal penalties can lead to imprisonment. The specific penalties are not detailed in the text provided, but they can vary based on the severity and circumstances of the breach. The legal framework ensures that these directives are strictly enforced to maintain the highest safety standards in air navigation.
In summary, the Civil Aviation Safety Regulations 1998, under regulation 39.001, provide the legal basis for CASA to issue ADs, which are essential for ensuring the continuing airworthiness of aircraft. These directives are issued in response to obligations under international conventions and the requirements of the State of Design. CASA’s role is pivotal in assessing and implementing these directives to ensure compliance and uphold safety standards. Non-compliance can lead to significant civil and criminal penalties, underscoring the importance of adhering to these regulations.
