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/BEECH 55/59 Amendment 1, affecting Beech 55 model aircraft in 1980. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 5 June 2008. No replacement AD is required, as the manufacturer’s maintenance manuals have been amended to include this requirement, and routine maintenance requirements are adequate.
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 a legal framework for the regulation of civil aviation in Australia, addressing the need for a comprehensive approach to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations that contribute to the safety of air navigation, with the Civil Aviation Safety Regulations 1998 establishing specific requirements, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The objective of these regulations is to maintain and ensure the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998, particularly under regulation 39.001, allow CASA to issue ADs, which are legislative instruments subject to disallowance. In response to international obligations and domestic needs, CASA has the responsibility to issue ADs that align with the requirements of the State of Design and ensure the safety standards are met by the State of Registry.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively establish a robust system for the regulation of airworthiness, ensuring that both international and domestic standards are upheld. This legislative framework is designed to protect public safety by mandating rigorous standards for aircraft maintenance and operation, thereby mitigating risks associated with civil aviation activities. The involvement of CASA in issuing and managing ADs underscores the importance of a coordinated and authoritative approach to airworthiness, ensuring that aircraft operating in Australian airspace meet necessary safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under 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 ADs serve as legislative instruments under the Acts Interpretation Act 1901 and are integral to maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design, which holds primary responsibility for the airworthiness of an aircraft type, issues ADs that CASA must assess and, if necessary, translate into Australian regulations. The State of Registry is also responsible for ensuring the continuing airworthiness of aircraft within its jurisdiction. CASA’s issuance of ADs, such as AD/BEECH 55/59 Amendment 1, reflects its role in enforcing safety standards in accordance with both national and international requirements. The cancellation of such ADs, when appropriate, reduces regulatory burden and is implemented without public consultation if it eases regulatory constraints, as determined by the Office of Best Practice Regulation. The authority to issue these directives lies with CASA, exercised by the Manager, Airframes in the Airworthiness Engineering Branch, under the provisions of the Civil Aviation Act 1988.
Key Provisions
The key sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are pivotal in governing the issuing of airworthiness directives (ADs) for aircraft. Section 98 of the Act empowers the Governor-General to create regulations that serve the safety interests of air navigation. Regulation 39.001 under the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for particular kinds of aircraft or aeronautical products. Moreover, subregulation 39.001(5) classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and by extension, as legislative instruments pursuant to section 6 of the Legislative Instruments Act 2003.
These regulations impose specific obligations on CASA and other entities involved in aircraft airworthiness. CASA, as Australia’s national airworthiness authority, is tasked with assessing information provided by the State of Design and determining whether an Australian AD is necessary to enforce the requirements of the State of Design. The State of Design, typically the country where the aircraft is designed, has the overarching responsibility for ensuring the continuing airworthiness of the aircraft type and must furnish any necessary information to the State of Registry. The State of Registry, which is responsible for the individual aircraft, must establish or adopt requirements to guarantee the aircraft's continuing airworthiness.
Failure to comply with the ADs can lead to various consequences. The Act and the Regulations do not explicitly detail the specific offences, penalties, or consequences for non-compliance with ADs. However, non-compliance generally results in the aircraft being deemed unairworthy, which could lead to serious safety risks and potential legal repercussions for operators. CASA's authority to enforce these regulations is crucial in maintaining the safety standards required in civil aviation.
