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/RES/4, affecting certain types of safety belts in 1967. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 22 November 2007. No replacement AD is required, as the original unsafe condition no longer exists, the affected belts having long been inspected and modified.
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, with a primary focus on ensuring the safety of air navigation. This legislation empowers the Governor-General to make regulations that serve the interests of aviation safety, and it grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments that mandate specific actions to ensure the continuing airworthiness of aircraft, aligning with international standards set out in Annex 8 to the Convention on International Civil Aviation. The policy objective is to maintain and enhance aviation safety by ensuring that all aircraft on the Australian Register meet the necessary airworthiness standards. CASA, as Australia's national airworthiness authority, is responsible for assessing and issuing ADs, reflecting its commitment to upholding stringent safety requirements in alignment with global best practices.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) to ensure the safety of air navigation in Australia. Specifically, regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue these directives for types of aircraft or aeronautical products. Such directives are considered legislative instruments under the Legislative Instruments Act 2003 and are subject to disallowance as per section 46A of the Acts Interpretation Act 1901. This legislative framework ensures that CASA, as Australia's national airworthiness authority, adheres to international standards set by the International Civil Aviation Organization (ICAO) under Annex 8 of the Convention on International Civil Aviation. The ADs are crucial for maintaining the continuing airworthiness of aircraft, with the State of Registry being ultimately responsible for compliance with these directives. In the instance of AD/RES/4, which dealt with specific types of safety belts, CASA has determined that the original unsafe condition no longer exists, leading to the cancellation of the directive, effective from 22 November 2007. This cancellation reflects the completion of necessary inspections and modifications on the affected belts and does not necessitate a replacement AD. The decision to cancel the AD was made without public consultation due to the reduction in regulatory burden, and it has been reviewed and approved by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 lay down the framework for issuing airworthiness directives (ADs), which are legal requirements to ensure the safety of aircraft. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations that support the Act, specifically for the safety of air navigation (s 98). Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further specifies that the Civil Aviation Safety Authority (CASA) can issue ADs for particular types of aircraft or aeronautical products (reg 39.001). Importantly, under subregulation 39.001(5), an AD is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore, it is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003.
Under these provisions, CASA, as Australia’s national airworthiness authority, has a critical role in ensuring that aircraft meet safety standards. Specifically, when the State of Design issues an AD for a type of aircraft registered in Australia, CASA must review this information and decide whether to issue an Australian AD to enforce the design state's requirements. This process is part of the international framework where the State of Design has overall responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must ensure that individual aircraft meet safety standards. This dual responsibility ensures that both the type and individual aircraft are maintained to a high standard of safety.
The obligations on CASA and other entities governed by these regulations are significant. CASA must assess the information provided by the State of Design and determine if an Australian AD is necessary. This assessment must be conducted with a view to ensuring the safety of air navigation and the continuing airworthiness of aircraft. The process also requires CASA to liaise with other regulatory bodies and ensure that any issued ADs are consistent with international standards set by the International Civil Aviation Organization (ICAO). In the case of AD/RES/4, which affected certain types of safety belts, CASA reviewed the AD and decided to cancel it, effective from 22 November 2007. This decision was based on the fact that the unsafe condition no longer existed, as the affected belts had been inspected and modified.
Failure to comply with ADs can lead to significant consequences. While the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 do not explicitly detail penalties for non-compliance with ADs, non-compliance with regulations generally can result in civil or criminal penalties. These can include fines and imprisonment, depending on the severity of the breach. CASA has the authority to enforce compliance and can take action against entities that fail to adhere to the ADs. The regulatory burden reduction due to the cancellation of AD/RES/4 was deemed not to require public consultation, as determined by the Office of Best Practice Regulation, which also concluded that ADs do not require a Regulatory Impact Statement. The AD cancellation was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
