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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/CESSNA 177/18 affecting Cessna 177RG model aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 31 July 2008. No replacement AD is required.
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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, addresses the regulation of civil aviation within Australia, with a focus on safety. Under the authority of this Act, the Governor-General is empowered to enact regulations that are essential for the safety of air navigation. One such regulation is the Civil Aviation Safety Regulations 1998, which provides the Civil Aviation Safety Authority (CASA) with the ability to issue airworthiness directives (ADs) for various types of aircraft and aeronautical products. These ADs are critical for maintaining the continuing airworthiness of aircraft, a responsibility that rests with the State of Registry as per Annex 8 of the Convention on International Civil Aviation. In accordance with Australia's international obligations, CASA has the authority to issue, review, and cancel ADs, ensuring compliance with safety standards and international conventions. In this instance, AD/CESSNA 177/18, affecting Cessna 177RG model aircraft, has been cancelled due to Australia's obligations under the Convention on International Civil Aviation, with no replacement AD required. This action was taken by CASA, following a review and in line with the legislative framework established by the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for the regulation of civil aviation safety in Australia. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These directives, which are considered legislative instruments, are critical for ensuring the continuing airworthiness of aircraft and are aligned with Australia's obligations under international conventions, such as Annex 8 to the Convention on International Civil Aviation. The State of Registry of an individual aircraft bears the responsibility for its ongoing airworthiness, and CASA issues ADs as part of this regulatory responsibility. The issuance and cancellation of ADs, such as AD/CESSNA 177/18 affecting Cessna 177RG model aircraft, are conducted under the authority of CASA, ensuring compliance with both domestic and international safety standards. Notably, the cancellation of ADs, like the one affecting the Cessna 177RG model, does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This process underscores CASA's role in maintaining the highest safety standards in civil aviation.
Key Provisions
The key operative sections of the Civil Aviation Safety Regulations 1998 relevant to the issue of airworthiness directives (ADs) are found in regulation 39.001 (subsection 5), which specifies that an AD is a legislative instrument. This means that ADs carry the force of law and must be complied with by the parties they govern. Regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs to ensure the continuing airworthiness of aircraft or aeronautical products. The Act and these regulations rely on the overarching responsibility of the State of Design, as outlined in Annex 8 to the Convention on International Civil Aviation, to provide necessary information to the State of Registry to maintain airworthiness.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on parties affected by ADs include ensuring compliance with the directives issued by CASA. For aircraft owners and operators, this means taking necessary actions such as inspections, repairs, or modifications as specified in the ADs to maintain the airworthiness of their aircraft. The State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft in their jurisdiction, which may include implementing and enforcing ADs. CASA, as the regulatory body, has the responsibility to issue ADs and ensure that they are in compliance with Australia's obligations under international conventions and regulations.
There are potential civil and administrative consequences for non-compliance with ADs. If an aircraft is operated in a manner that does not comply with an AD, it may be deemed unairworthy, leading to potential grounding of the aircraft. Operators who fail to comply with ADs may face enforcement actions from CASA, which could include fines, suspension or revocation of airworthiness certificates, and other administrative penalties. While specific penalties are not detailed in the provided text, they are typically outlined in other sections of the Civil Aviation Act 1988 and related regulations. The severity of penalties may depend on the nature and extent of the non-compliance, as well as any resulting safety risks.
