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 Civil Aviation Safety Authority or its predecessors issued AD/AA-5/6 affecting Gulfstream AA-5 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-5/6. The cancellation will become effective on 4 June 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia, ensuring safety and efficiency in air navigation. As part of this legislative framework, the Civil Aviation Safety Regulations 1998 were established, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning aircraft types or aeronautical products. These ADs are critical tools for maintaining the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. The issuance and cancellation of ADs, such as the recent cancellation of AD/AA-5/6 affecting Gulfstream AA-5 model aircraft, are integral to upholding safety standards and are managed by CASA in accordance with the statutory provisions and international obligations. This legislative mechanism ensures that Australia adheres to its commitments under the Convention while safeguarding the safety of its airspace.
Scope and Application
The Civil Aviation Safety Regulations 1998, as an extension of the Civil Aviation Act 1988, apply to all aircraft and aeronautical products registered within Australia. The regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that are binding and enforceable under the legislative framework. These directives are crucial for ensuring the ongoing airworthiness of aircraft and aeronautical products, addressing any safety issues that may arise. As part of the regulatory process, CASA must assess and respond to ADs issued by the State of Design, ensuring that they meet the safety standards required under international and national laws. The scope of ADs extends to mandating specific requirements for aircraft registered in Australia, reflecting the overarching responsibility of the State of Registry under the Convention on International Civil Aviation. Notably, ADs are considered disallowable instruments under the Acts Interpretation Act 1901, and as such, they are legislative instruments as defined in the Legislative Instruments Act 2003. The application of these regulations is comprehensive, covering all aircraft and aeronautical products within the Australian jurisdiction, without specified exclusions or exemptions.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation in Australia. Section 98 of the Act allows the Governor-General to make regulations for the purposes of the Act, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. ADs are legislative instruments, as stated under section 46A of the Acts Interpretation Act 1901, and they are a critical form of continuing airworthiness information as per Annex 8 to the Convention on International Civil Aviation.
Under the Civil Aviation Act 1988 and the associated regulations, CASA is mandated to assess information provided by the State of Design and, if necessary, issue Australian ADs to ensure the continuing airworthiness of aircraft. When an AD is issued by the State of Design, CASA must evaluate the information and decide whether to issue an Australian AD to enforce the requirements. This ensures that the safety standards are upheld as per Australia’s obligations under international conventions. Moreover, the State of Registry, in this case CASA, has the responsibility to ensure the ongoing airworthiness of individual aircraft registered in Australia. This involves developing or adopting the necessary requirements to maintain the safety of the aircraft.
Any breach of the ADs or failure to comply with the continuing airworthiness requirements can result in significant consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose strict obligations on aircraft owners, operators, and maintenance personnel to adhere to the issued ADs. Non-compliance can lead to enforcement actions by CASA, including fines and penalties. The severity of the penalties depends on the nature and extent of the non-compliance, but they can be substantial, reflecting the critical importance of air safety. Furthermore, any failure to adhere to ADs can compromise the safety of air navigation, potentially leading to severe civil or criminal consequences.
The Civil Aviation Safety Regulations 1998 do not require consultation with the Australian public or a Regulatory Impact Statement for ADs, as determined by the Office of Best Practice Regulation. ADs are issued by authorised personnel within CASA, ensuring that the process is rigorous and compliant with the legislative framework. This ensures that the ADs are effective in maintaining the high safety standards required in the aviation industry. The issuance, assessment, and cancellation of ADs are carried out in accordance with the legislative provisions, ensuring that the safety of air navigation is prioritised at all times.
