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.
The Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 206/19 affecting Cessna U206 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 206/19. The cancellation will become effective on 23 October 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a comprehensive legal framework governing civil aviation in Australia, ensuring safety and efficiency in air navigation and operations. In 1998, the Civil Aviation Safety Regulations were introduced to provide further detail and enforce compliance with the Act's provisions. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to create regulations in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, making these directives legislative instruments subject to disallowance. This legislative framework is designed to align Australia's aviation safety standards with international obligations, particularly those under the Convention on International Civil Aviation, which mandates that the State of Design bear responsibility for an aircraft type's continuing airworthiness. Consequently, CASA is obligated to assess and potentially issue Australian ADs when necessary to maintain the airworthiness of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework within which airworthiness directives (ADs) are issued in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific kinds of aircraft or aeronautical products to ensure the continuing safety of air navigation. These ADs are legislative instruments, subject to disallowance, and must align with international standards as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Design retains overall responsibility for the airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure the compliance and safety of aircraft registered within Australia. The process involves CASA assessing information from the State of Design and, if necessary, issuing an Australian AD. For instance, AD/CESSNA 206/19 was issued for Cessna U206 model aeroplanes but has since been cancelled due to the resolution of the unsafe condition, without the need for public consultation or a Regulatory Impact Statement. The issuance and cancellation of such ADs are managed by designated CASA personnel in accordance with the Act's provisions.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 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 intended to ensure the safety of air navigation and are grounded in the overarching framework established by the Civil Aviation Act 1988 (section 98). As stated in subregulation 39.001(5), an AD is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and consequently, it is considered a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003.
In practical terms, an AD mandates specific actions or conditions that must be met to maintain the airworthiness of a particular aircraft type. For example, CASA issued AD/CESSNA 206/19 concerning Cessna U206 model aeroplanes, which was subsequently assessed and cancelled on 23 October 2008 due to the resolution of the unsafe condition it addressed. This cancellation highlights the regulatory process where CASA, as the national airworthiness authority, evaluates ADs issued by the State of Design and determines their applicability to aircraft registered in Australia.
Entities governed by these regulations, particularly aircraft operators and manufacturers, must adhere to the requirements set forth in any applicable ADs. This involves conducting necessary inspections, maintenance actions, or modifications as specified in the AD to ensure the aircraft remains airworthy. Operators must keep records of compliance with these directives and report any non-compliance to CASA. Failure to adhere to the stipulations of an AD can result in serious consequences, as these directives are integral to the safety oversight of civil aviation.
In terms of legal ramifications, breaches of the requirements set out in an AD can result in civil or criminal penalties. The specific consequences may include fines, imprisonment, or both, depending on the nature and severity of the non-compliance. Under the Civil Aviation Act 1988, the maximum penalties for non-compliance with ADs can be substantial, reflecting the critical importance of airworthiness directives in maintaining the safety standards of the aviation industry.
