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 55/71, affecting Beech 55 model aircraft in 1988. 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 all affected aircraft would have been inspected, and if necessary modified, long ago.
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 ensure the safety of air navigation in Australia, providing the legal framework for the regulation of civil aviation. The Act empowers the Governor-General to make regulations that serve the interests of aviation safety, with the Civil Aviation Safety Regulations 1998 further detailing these regulations. One such regulation is the issuance of airworthiness directives (ADs), which are legislative instruments under subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998. These ADs are essential for maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) issues ADs to enforce airworthiness requirements, ensuring compliance with international standards. In line with these provisions, CASA has decided to cancel AD/BEECH 55/71, effective from 5 June 2008, after reviewing the directive and determining that no further action is necessary for the affected aircraft.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) playing a central role in ensuring the safety and continuing airworthiness of aircraft registered in Australia. Pursuant to section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations in the interest of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers CASA to issue ADs for types of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003. The ADs serve as a mechanism for continuing airworthiness information, mandated by Annex 8 to the Convention on International Civil Aviation, where the State of Design is responsible for ensuring the continuing airworthiness of an aircraft type and the State of Registry must enforce these requirements domestically. CASA, as Australia's national airworthiness authority, is obligated to issue corresponding ADs when necessary, following the assessment of information from the State of Design. For instance, CASA issued and subsequently cancelled AD/BEECH 55/71 concerning Beech 55 model aircraft, reflecting the completion of required inspections and modifications. This cancellation, which does not require public consultation or a Regulatory Impact Statement, underscores the efficiency and responsiveness of the regulatory framework in reducing unnecessary regulatory burdens.
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. These directives are formal instruments designed to ensure the continuing airworthiness of aircraft, and they are critical for maintaining safety standards in air navigation. Section 98 of the Civil Aviation Act 1988 underpins this regulatory power, allowing for the creation of such directives in the interests of safety. Importantly, subregulation 39.001(5) classifies ADs as disallowable instruments under the Acts Interpretation Act 1901, making them subject to parliamentary scrutiny. They are also legislative instruments as defined by section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and Regulations on parties such as aircraft manufacturers, operators, and CASA are substantial. The State of Design, which is responsible for the initial airworthiness of a specific aircraft type, must provide all necessary information to ensure its continuing airworthiness. The State of Registry, which oversees the individual aircraft's ongoing compliance with safety standards, must then either develop or adopt requirements to maintain this airworthiness. CASA, acting on behalf of Australia, is mandated to assess any ADs issued by the State of Design and, if necessary, issue equivalent Australian ADs. This ensures that Australian aircraft meet internationally recognised safety standards.
Failure to comply with an airworthiness directive can lead to severe consequences. Under the Civil Aviation Act 1988, non-compliance can result in civil penalties, which may include fines and other sanctions. In more serious cases, CASA can take enforcement actions, such as grounding non-compliant aircraft, which can have significant operational and financial repercussions for aircraft operators. Furthermore, if non-compliance leads to an accident or incident, it can result in criminal charges, potentially leading to imprisonment for responsible parties. The specific penalties vary depending on the severity and intent behind the breach, but they underscore the critical importance of adhering to ADs.
