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/BEECH 35/16 affecting Beech 35 type/model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 35/16. 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 ensure the safety of air navigation and to establish the regulatory framework for civil aviation in Australia. This Act was introduced to address the need for a comprehensive legal framework governing the safety and regulation of civil aviation within Australia, aligning with international standards and obligations. The Civil Aviation Safety Regulations 1998 further support the Act by providing detailed rules and procedures for maintaining airworthiness, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are essential for ensuring that aircraft and aeronautical products continue to meet safety standards, as mandated by Annex 8 to the Convention on International Civil Aviation. The authority to issue these directives is exercised by CASA, which acts in accordance with Australia’s obligations under international conventions, ensuring that the continuing airworthiness of aircraft is maintained in line with global safety standards.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, establishes the framework for ensuring the safety of air navigation in Australia, with specific emphasis on the continuing airworthiness of aircraft. Under this Act, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001. These directives are legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901, as well as regulation in accordance with the Legislative Instruments Act 2003. The ADs serve to address safety concerns and ensure compliance with international standards as outlined in 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, is tasked with ensuring the continuing airworthiness of individual aircraft registered in Australia. This involves assessing international ADs and, if necessary, issuing Australian ADs to enforce the required safety measures. The Act and its regulations apply to all aircraft and aeronautical products within Australia, affecting both operators and manufacturers who must adhere to the airworthiness directives issued by CASA.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation. Specifically, section 98 of the Act empowers the Governor-General to make regulations that serve the interests of air navigation safety. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003. ADs are an essential mechanism for maintaining the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation, which places the responsibility for the continuing airworthiness of an aircraft type on the State of Design.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require the State of Design to provide necessary information to ensure the continuing airworthiness of an aircraft type to the State of Registry. The State of Registry, in turn, is responsible for the continuing airworthiness of individual aircraft and must develop or adopt requirements to ensure this. In Australia, CASA acts as the national airworthiness authority and must assess any ADs issued by the State of Design against aircraft types on the Australian Register. If deemed appropriate, CASA may issue an Australian AD to enforce the requirements of the State of Design. This process was exemplified when CASA assessed and subsequently cancelled Australian AD/BEECH 35/16, affecting Beech 35 type/model aircraft, due to the unsafe condition no longer existing. This cancellation was made in accordance with Australia's obligations under the Convention on International Civil Aviation and became effective on 10 April 2008.
The legislation also addresses the consequences of non-compliance with airworthiness directives. Under the Civil Aviation Act 1988, failure to comply with an AD can result in serious safety risks and potential penalties. CASA has the authority to enforce compliance, and non-compliance can lead to civil or criminal penalties. Specifically, the Act provides for penalties that can include fines and imprisonment, reflecting the severity of endangering public safety through non-compliance with airworthiness directives. The exact penalties are determined based on the nature and severity of the offence, but the overarching goal is to ensure that all parties adhere to the safety requirements to prevent accidents and maintain the highest standards of air navigation safety.
