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.
Transport Canada has issued AD CF-2005-21 affecting Bombardier CL600 series aircraft. Canada is the State of Design for these aircraft. CASA has assessed this AD and has issued Australian AD/CL-600/66, which will become effective on 29 September 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 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 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. This legislation empowers the Governor-General to create regulations that promote the safety of air navigation, thereby fulfilling Australia’s obligations under international agreements such as the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 further delineate the responsibilities and processes for maintaining aircraft airworthiness, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These directives are critical in maintaining the continuing airworthiness of aircraft and are issued in response to safety concerns identified by the aircraft's State of Design or in accordance with international standards. The ADs are legislative instruments subject to disallowance and review, and their issuance often does not require public consultation due to their alignment with international obligations. This legislative framework is designed to ensure that aircraft operating in Australia meet the necessary safety standards, thereby protecting the public and maintaining the integrity of the nation's aviation safety system.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, provide the authority for the Civil Aviation Safety Administration (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are legislative instruments that serve to ensure the safety of air navigation, and are mandated under the State of Design's responsibility as outlined in Annex 8 to the Convention on International Civil Aviation. In Australia, CASA, acting as the national airworthiness authority, is tasked with assessing ADs issued by the State of Design and, if deemed necessary, issuing corresponding Australian ADs to enforce the required safety measures. This process applies to aircraft registered in Australia, ensuring compliance with international safety standards. The issuance of these directives is a formal process undertaken by CASA, reflecting Australia's commitment to international aviation safety agreements, and does not require public consultation as it is directly tied to international obligations and assessments.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, under section 98 and regulation 39.001 respectively. An AD is a legislative instrument that mandates certain actions or conditions to ensure the continuing airworthiness of the aircraft, as per subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901. These directives are crucial for maintaining safety standards as they are the primary means of communication for continuing airworthiness information, as outlined in Annex 8 of the Convention on International Civil Aviation. The State of Design, which is the country where the aircraft is designed, is responsible for ensuring that the aircraft remain airworthy, and must provide necessary information to the State of Registry, which is the country where the aircraft is registered. In this context, Australia, through CASA, must assess and, if necessary, issue an Australian AD when the State of Design issues one.
Entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 have specific obligations regarding airworthiness directives. CASA, as the national airworthiness authority, must review and assess any airworthiness directive issued by the State of Design, such as Transport Canada's AD CF-2005-21 for Bombardier CL600 series aircraft. Upon assessment, if deemed necessary, CASA must issue a corresponding Australian AD to enforce the same requirements within the Australian context. This ensures that all aircraft registered in Australia comply with international safety standards and are maintained in a safe and airworthy condition. Additionally, the State of Registry is responsible for implementing and enforcing these ADs to ensure the continuing airworthiness of the aircraft within their jurisdiction.
The Act and Regulations also outline the consequences for non-compliance with airworthiness directives. Failure to comply with an AD can lead to severe penalties and legal consequences. While the specific penalties are not detailed in the provided text, non-compliance with airworthiness requirements generally results in the inability to legally operate the aircraft, potentially leading to fines, suspension or revocation of the aircraft's certificate of airworthiness, and even criminal charges in severe cases. These measures are critical to enforcing the safety standards set forth by international conventions and national regulations, ensuring that all aircraft maintain the highest levels of safety and airworthiness.
Given that these airworthiness directives are issued in response to international obligations and the specific requirements of the State of Design, the Act exempts them from certain procedural requirements, such as public consultation and the need for a Regulatory Impact Statement. This streamlined process ensures that critical safety information is communicated and implemented swiftly without unnecessary delays. The ADs are made by authorised officials within CASA, such as the Manager, New Technologies and Systems, in accordance with the legislative framework provided by the Act. This process underscores the importance of adhering to international standards and the efficiency required in managing airworthiness directives to maintain aviation safety.
