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.
CASA issued AD/AC-SNOW/10 affecting Ayres Thrush series aircraft in 1968. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Airframes 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 regulate civil aviation in Australia, ensuring safety and efficiency in the industry. The Act provides the legislative framework for the Civil Aviation Safety Regulations 1998, which include provisions for the issuance of airworthiness directives (ADs). ADs are legislative instruments that mandate specific safety measures for certain types of aircraft or aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Act empowers the Civil Aviation Safety Authority (CASA), Australia’s national airworthiness authority, to issue ADs to ensure the continuing airworthiness of aircraft registered in Australia. This regulatory approach is crucial in maintaining high safety standards and mitigating risks associated with civil aviation. The policy objective is to enhance aviation safety by implementing necessary measures in response to identified safety issues, as demonstrated by CASA’s recent decision to cancel an outdated AD affecting Ayres Thrush series aircraft, reflecting ongoing efforts to streamline and update safety regulations.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, encompasses various measures to ensure the safety of air navigation, with a particular focus on the issuance of airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue these directives, which are considered disallowable instruments under the Acts Interpretation Act 1901. Consequently, an AD is classified as a legislative instrument under the Legislative Instruments Act 2003. These regulations apply to entities such as aircraft manufacturers and operators, ensuring that they adhere to standards that maintain the safety and airworthiness of aircraft within Australia. The geographic reach of these regulations is national, as Australia’s obligations under Annex 8 to the Convention on International Civil Aviation require coordination between the State of Design and the State of Registry, with CASA playing a pivotal role in enforcing these standards domestically. The scope of application extends to all aircraft types registered within Australia, mandating compliance with issued airworthiness directives to ensure ongoing safety and airworthiness.
Key Provisions
The Civil Aviation Safety Regulations 1998 under section 39.001 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are intended to ensure the continuing airworthiness of aircraft, which is a critical aspect of aviation safety. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations that serve the interests of air navigation safety, and regulation 39.001 is a prime example of this. An AD is a legislative instrument that can be disallowed under section 46A of the Acts Interpretation Act 1901, and it is subject to the Legislative Instruments Act 2003.
The obligations imposed by these regulations are multifaceted. The State of Design is tasked with the overall responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry to ensure safety. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. For instance, when CASA, Australia's national airworthiness authority, receives an AD from a State of Design, it must assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that all aircraft registered in Australia meet the necessary safety standards.
In terms of compliance and enforcement, any breach of the ADs or regulations could lead to significant civil or criminal consequences. Although specific offences and penalties are not detailed in the text, the issuance and enforcement of ADs are critical for maintaining safety standards in aviation. Failure to comply with an AD could potentially result in penalties under the Civil Aviation Act 1988 or other relevant legislation. It is essential that all parties adhere to these directives to avoid any adverse outcomes, which could include fines, suspension of operations, or other regulatory actions. The seriousness of these potential penalties underscores the importance of complying with the ADs.
