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/CESSNA 336/6, affecting Cessna 336 model aircraft in 1971. 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 provide for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. This Act allows for the creation of regulations to maintain the safety of air navigation, including the issuance of airworthiness directives (ADs). The Civil Aviation Safety Regulations 1998 further detail the procedures under which ADs can be issued, with regulation 39.001 authorising the Civil Aviation Safety Authority (CASA) to mandate ADs for specific aircraft or aeronautical products. In line with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation, the State of Design holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type, while the State of Registry, such as Australia, must implement the necessary measures to maintain the airworthiness of registered aircraft. CASA, as Australia’s national airworthiness authority, plays a critical role in this process by assessing and, when necessary, issuing Australian ADs that reflect the requirements of the State of Design. The regulatory framework is designed to ensure that air travel remains safe and that Australian standards align with international best practices.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments, as stipulated by the Legislative Instruments Act 2003, and aim to ensure the continuing airworthiness of aircraft registered in Australia. Such directives typically align with international standards set by the International Civil Aviation Organization (ICAO). CASA, acting as Australia's national airworthiness authority, is responsible for assessing and, if necessary, issuing Australian ADs in response to directives from the State of Design or other relevant authorities. The scope of these directives extends to all aircraft registered within Australia, thereby affecting aircraft owners, operators, and maintenance providers within the country. While the ADs are intended to enhance safety and comply with international standards, there are no stated exclusions or thresholds within the provided text, and any exemptions or modifications to the application of these directives would likely be detailed in subordinate instruments or specific regulatory guidance.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 98 of the Civil Aviation Act 1988 further supports this by allowing the Governor-General to make regulations that are necessary for the safety of air navigation. An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is classified as a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003. This regulatory framework ensures that CASA can mandate safety measures and maintain the airworthiness of aircraft registered in Australia.
The obligations under the Civil Aviation Safety Regulations 1998 require CASA to closely monitor the airworthiness of aircraft types registered in Australia. When a State of Design issues an AD for a specific aircraft type, CASA must review and assess this information. If deemed necessary, CASA can issue its own AD to enforce the safety requirements specified by the State of Design. This obligation ensures that Australian-registered aircraft meet international safety standards and continue to be airworthy. The State of Registry, which is the country where an aircraft is registered, is also responsible for ensuring the ongoing airworthiness of the aircraft, developing or adopting the necessary requirements to maintain this standard.
The Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 establish several consequences for non-compliance with ADs. Any breach of these regulations can lead to civil or criminal penalties, depending on the severity of the violation. For example, if an operator fails to comply with an AD, CASA may issue a Notice of Proposed Civil Penalty (NOPC) or initiate legal proceedings. The maximum penalties for non-compliance can include fines or imprisonment, reflecting the critical nature of adhering to airworthiness directives to ensure the safety of air navigation. CASA has the authority to enforce these regulations rigorously to maintain high safety standards within the Australian aviation industry.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for issuing and enforcing airworthiness directives. CASA's role in assessing and implementing ADs is crucial for maintaining the safety and airworthiness of aircraft registered in Australia. The obligations on both CASA and the States of Registry ensure that all aircraft meet the necessary safety standards. The potential penalties for non-compliance underscore the importance of adhering to these regulations to protect the public and maintain the integrity of the aviation industry.
