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/CESSNA 207/3 affecting Cessna 207 and T207 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 207/3. The cancellation will become effective on 25 September 2008. 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 provide for the safety and efficiency of civil aviation in Australia, including the regulation of airworthiness and the issuance of airworthiness directives. The Act empowers the Governor-General to make regulations for the purposes of the Act, with the overarching goal of ensuring the safety of air navigation. Under the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives for specific kinds of aircraft or aeronautical products. As stipulated in section 39.001(5) of the Regulations, these directives are legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. In line with international obligations under Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure the continuing airworthiness of aircraft registered in Australia. The AD/CESSNA 207/3, initially issued for Cessna 207 and T207 model aeroplanes, has been cancelled by CASA following an assessment that the unsafe condition it addressed no longer exists, thereby fulfilling Australia’s international obligations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation in Australia. Under these laws, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are considered legislative instruments and serve to maintain the continuing airworthiness of aircraft registered in Australia, in compliance with the Convention on International Civil Aviation. The State of Design holds primary responsibility for the airworthiness of an aircraft type, while the State of Registry is tasked with ensuring the ongoing airworthiness of individual aircraft. CASA, as Australia’s national airworthiness authority, evaluates ADs issued by other contracting states and may issue Australian ADs as necessary. For instance, CASA issued and subsequently cancelled AD/CESSNA 207/3 for Cessna 207 and T207 model aeroplanes, reflecting changes in safety assessments and obligations under international conventions. The process of issuing or cancelling ADs does not typically require public consultation or a Regulatory Impact Statement, and the specific ADs are created by authorised personnel within CASA, adhering to the provisions outlined in the Act.
Key Provisions
The Civil Aviation Act 1988, particularly under section 98, empowers the Governor-General to issue regulations that are vital for the safety of air navigation. This includes the issuance of airworthiness directives (ADs) as specified in regulation 39.001 of the Civil Aviation Safety Regulations 1998. An AD is a formal legislative instrument that mandates specific safety measures for certain types of aircraft or aeronautical products. According to subregulation 39.001(5), these directives are disallowable instruments as per section 46A of the Acts Interpretation Act 1901, and they are classified as legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant. The State of Design, which is the country where the aircraft was originally designed, holds primary responsibility for the continuing airworthiness of an aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. This State must furnish any necessary information to ensure the continuing airworthiness of the aircraft to the States of Registry. Meanwhile, the State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft within its jurisdiction. In Australia, the Civil Aviation Safety Authority (CASA) acts as the national airworthiness authority and must assess any ADs issued by the State of Design, issuing its own Australian AD if appropriate.
In terms of compliance and enforcement, any breach of the requirements outlined in an AD can lead to serious consequences. Although specific penalties are not detailed in the text, it is reasonable to infer that non-compliance with ADs could result in enforcement actions by CASA, potentially leading to fines, legal proceedings, or other administrative sanctions under the Civil Aviation Act 1988. Given that ADs are crucial for maintaining safety standards, failure to adhere to these directives can compromise the safety of air navigation, leading to significant legal and operational repercussions.
In summary, the Civil Aviation Act 1988 and associated regulations establish a robust framework for ensuring the continuing airworthiness of aircraft through the issuance and enforcement of airworthiness directives. These directives are integral to meeting international standards and ensuring the safety of air navigation, with CASA playing a pivotal role in their assessment and implementation in Australia.
