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 35/56, affecting Beech 35 model aircraft in 1984. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 13 March 2008. No replacement AD is required, as the original unsafe condition no longer exists.
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, with a primary focus on ensuring the safety of air navigation. This Act grants the Governor-General the authority to issue regulations necessary for the Act's objectives, as seen in the Civil Aviation Safety Regulations 1998. The problem or gap this Act addresses includes the need for a comprehensive legislative framework that can respond to the evolving complexities of civil aviation safety, including the issuance of airworthiness directives to maintain the continuing airworthiness of aircraft. These regulations empower the Civil Aviation Safety Authority (CASA) to issue such directives, which are critical for maintaining safety standards and ensuring compliance with international obligations under the Convention on International Civil Aviation. The policy objective is to facilitate effective regulation that supports the safe and efficient operation of aircraft, thereby protecting public safety and maintaining Australia's commitment to international aviation standards.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) aimed at ensuring the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises CASA to issue ADs for particular kinds of aircraft or aeronautical products. These ADs serve as legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and are subject to the requirements of the Legislative Instruments Act 2003. The application of the Act and its regulations extends to all aircraft registered in Australia, with CASA acting as the national airworthiness authority responsible for ensuring the continuing airworthiness of these aircraft in line with international standards set by the International Civil Aviation Organization (ICAO). While the Act and its regulations broadly apply to all aircraft within Australia’s jurisdiction, specific ADs are targeted at identified types of aircraft or aeronautical products when safety concerns are identified. The issuance of ADs is a critical tool for CASA to mandate necessary safety measures and ensure compliance with both national and international safety standards.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises CASA to issue these directives, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make such regulations for the safety of air navigation.
Compliance with ADs is mandatory for the parties they govern. For instance, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry. The State of Registry, in turn, must ensure the continuing airworthiness of individual aircraft by developing or adopting relevant requirements. When the State of Design issues an AD, CASA must assess it and, if appropriate, issue a corresponding Australian AD to enforce the State of Design’s requirements.
Recent actions taken by CASA include the cancellation of AD/BEECH 35/56, which affected Beech 35 model aircraft originally issued in 1984. This cancellation, effective from 13 March 2008, reflects the resolution of the original unsafe condition, thus negating the need for a replacement AD. No public consultation was required for this cancellation as it reduces regulatory burden, and the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement.
Breach of airworthiness directives or failure to comply with mandated safety requirements can lead to serious legal consequences. The Act and Regulations outline specific offences and penalties for non-compliance, which may include criminal charges, fines, and other sanctions. These provisions are designed to ensure that all parties adhere to the stringent safety standards required in the aviation sector.
