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 188/34, affecting Cessna 188 model aircraft in 1980. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 14 February 2008. No replacement AD is required, as the original unsafe condition has long ceased to exist.
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 comprehensive framework for the regulation of civil aviation in Australia, addressing various aspects of aviation safety and administration. The Act empowers the Governor-General to make regulations necessary for the safety of air navigation, with specific provisions enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives. These directives are essential for ensuring the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998 further detail the regulatory process, including the issuance of airworthiness directives as legislative instruments. The policy objective of these regulations is to enhance aviation safety by maintaining and enforcing airworthiness standards in accordance with international conventions and national requirements.
The Civil Aviation Act 1988 and its associated regulations were established by the Parliament of Australia to ensure that civil aviation activities within the country are conducted safely and efficiently. CASA, acting under the authority granted by the Act, has the responsibility to issue and manage airworthiness directives to address safety issues related to aircraft types registered in Australia. The legislative framework supports the overarching goal of maintaining high safety standards in civil aviation, facilitating compliance with international obligations while catering to the specific needs of the Australian aviation sector.
Scope and Application
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This authority is derived from section 98 of the Act and regulation 39.001 of the Regulations, which allow for the creation of ADs in the interests of air navigation safety. ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003, and their issuance aligns with Annex 8 of the Convention on International Civil Aviation, where the State of Design and the State of Registry share responsibilities for the continuing airworthiness of aircraft. CASA, as Australia's national airworthiness authority, must assess information from the State of Design and issue corresponding Australian ADs where necessary. For instance, CASA issued AD/CESSNA 188/34 in 1980, which has since been cancelled, effective 14 February 2008, due to the resolution of the original safety concern. This cancellation does not require public consultation or a Regulatory Impact Statement, as it reduces the regulatory burden, and no replacement AD is deemed necessary. The AD was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Key Provisions
The Civil Aviation Safety Regulations 1998 provide that the Civil Aviation Safety Authority (CASA) may issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, pursuant to section 98 of the Civil Aviation Act 1988 (section 39.001). An AD is defined as a disallowable instrument under the Acts Interpretation Act 1901 (subregulation 39.001(5)) and is considered a legislative instrument under the Legislative Instruments Act 2003 (section 6). These directives serve as a primary means of ensuring the continuing airworthiness of aircraft types, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design holds overall responsibility for the airworthiness of an aircraft type and must provide necessary information to ensure its airworthiness to States of Registry. The State of Registry, in turn, is responsible for the airworthiness of individual aircraft and must develop or adopt requirements to ensure this.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to assess any ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs to enforce the requirements for aircraft registered in Australia. This process ensures that Australian aircraft comply with international standards and that safety is maintained across the aviation sector. CASA's role in issuing and enforcing ADs is critical, as it directly impacts the safety and airworthiness of aircraft operating within Australia.
Failure to comply with ADs can result in severe consequences. Section 98 of the Civil Aviation Act 1988 empowers CASA to take enforcement actions against non-compliant aircraft and operators. Such actions may include grounding the aircraft until the required actions are completed, imposing fines, or taking legal action against the aircraft owner or operator. The severity of penalties varies depending on the nature and extent of the non-compliance, but can include substantial financial penalties and, in extreme cases, criminal charges. The regulations are designed to ensure that all aircraft meet the necessary safety standards, thereby protecting both the public and the aviation industry.
