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 55/31 affecting Beechcraft 55 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 55/31. The cancellation will become effective on 5 June 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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, establishes a legislative framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations in the interests of air navigation safety, with a particular focus on airworthiness directives (ADs). These ADs, issued by the Civil Aviation Safety Authority (CASA), mandate the ongoing airworthiness of aircraft and aeronautical products as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. The Civil Aviation Act 1988 addresses the need for a cohesive and enforceable regulatory approach to aviation safety in Australia, aligning with international standards and obligations under the Convention on International Civil Aviation. The policy objective is to maintain high safety standards in civil aviation by ensuring that all aircraft meet required airworthiness criteria.
Scope and Application
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance and management of airworthiness directives (ADs) in Australia, ensuring the ongoing safety of air navigation. Under these regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001. These directives are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type and must share necessary information with States of Registry, such as Australia, to maintain safety standards. CASA, as Australia's national airworthiness authority, must review this information and, if necessary, issue corresponding Australian ADs to enforce the requirements set by the State of Design. This legislative framework ensures that all relevant entities and individuals comply with safety standards, maintaining the integrity of air navigation within Australia.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia, with section 98 of the Act (1) empowering the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 (2) specifically allowing the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003 and are disallowable under section 46A of the Acts Interpretation Act 1901.
The obligations imposed on CASA under this legislation are significant. As Australia’s national airworthiness authority, CASA must ensure the continuing airworthiness of aircraft registered in Australia, in compliance with Annex 8 to the Convention on International Civil Aviation. This means that when the State of Design issues an AD for a type of aircraft on the Australian Register, CASA must evaluate this information and, if necessary, issue a corresponding Australian AD to enforce the State of Design's requirements. This ensures that Australian aircraft meet international safety standards and are maintained in a safe condition for operation.
Failure to comply with ADs can lead to serious consequences. Section 84A of the Civil Aviation Act 1988 outlines the offences and penalties associated with non-compliance with ADs. Pilots, owners, and operators of aircraft who fail to comply with ADs may face substantial fines and potential imprisonment. The exact penalties depend on the severity of the non-compliance, but they can be severe, reflecting the critical importance of air safety. Furthermore, CASA has the authority to take enforcement actions, including grounding aircraft that do not meet the required safety standards.
The Civil Aviation Safety Authority has recently cancelled Australian AD/BEECH 55/31, which affected Beechcraft 55 model aircraft. This decision followed a thorough assessment by CASA, which determined that the unsafe condition no longer existed. As a result, the cancellation of this AD will become effective on 5 June 2008, and no replacement AD is required. This action underscores the dynamic nature of airworthiness regulations and the continuous efforts of CASA to ensure the safety of aircraft in Australia.
