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 210/23 affecting Cessna 210 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 210/23. The cancellation will become effective on 10 April 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 Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a comprehensive framework for civil aviation regulation in Australia, ensuring safety and efficiency in the national airspace. Under this Act, the Governor-General has the authority to issue regulations that serve the interests of air navigation safety. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are essential for maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 of the Convention on International Civil Aviation. CASA, acting as Australia’s national airworthiness authority, must evaluate and, if necessary, issue Australian ADs to align with directives issued by the State of Design. This legislative structure aims to ensure that all aircraft registered in Australia meet international safety standards and to maintain the highest safety protocols within Australian airspace.
Scope and Application
The Civil Aviation Act 1988, specifically under regulation 39.001 of the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft and aeronautical products within Australia. This regulatory mechanism is part of the broader international commitment under Annex 8 to the Convention on International Civil Aviation, where the State of Design holds the responsibility for the continuing airworthiness of aircraft types, and the State of Registry must implement and enforce necessary measures to maintain airworthiness. The ADs issued by CASA, including the cancellation of Australian AD/CESSNA 210/23, reflect Australia’s adherence to these international standards, ensuring that the continuing airworthiness of aircraft registered in Australia aligns with global safety protocols. The ADs are legislative instruments that can be issued without public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation, given their technical nature and the specific obligations under international aviation conventions.
Key Provisions
The Civil Aviation Act 1988 provides the legislative framework for the regulation of civil aviation in Australia. Section 98 allows the Governor-General to make regulations for the purposes of the Act and for the safety of air navigation. In this context, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Subregulation 39.001(5) clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, making it a legislative instrument in its own right. This legal status is further affirmed under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions primarily fall on CASA as the national airworthiness authority. Under Annex 8 to the Convention on International Civil Aviation, the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the appropriate States of Registry. In Australia, CASA must assess this information and, if deemed appropriate, issue an Australian AD to enforce the requirements set by the State of Design. This ensures that aircraft registered in Australia meet the necessary safety standards. Additionally, the State of Registry is responsible for the ongoing airworthiness of individual aircraft and must develop or adopt requirements to maintain these standards.
In the specific case of the Cessna 210 aircraft, CASA issued AD/CESSNA 210/23. After a thorough assessment, CASA determined that the unsafe condition addressed by this AD no longer existed and subsequently cancelled the directive. This cancellation took effect on 10 April 2008, and no replacement AD was necessary. The decision to cancel the AD was made in line with Australia's obligations under the Convention on International Civil Aviation, hence no public consultation was required. Moreover, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement.
There are potential civil and criminal consequences for non-compliance with ADs. While the specific penalties are not detailed in the provided text, it is understood that failure to adhere to an AD can result in serious safety risks, which may lead to enforcement actions by CASA. These actions could include fines, suspension, or revocation of aircraft certificates of airworthiness, and in severe cases, criminal charges against individuals or companies responsible for non-compliance. The precise penalties would depend on the nature and severity of the non-compliance, as well as relevant provisions within the Civil Aviation Act 1988 and other related legislation.
