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.
The Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 303/1 affecting Cessna T303, 1982 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 303/1. The cancellation will become effective on 25 September 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 provide for the regulation of civil aviation in Australia, particularly focusing on the safety of air navigation. Under this Act, the Governor-General is empowered to make regulations, including the issuance of airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, allowing the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This regulatory framework is designed to align with international standards, particularly those set by the International Civil Aviation Organization (ICAO), which mandates that the State of Design holds responsibility for the continuing airworthiness of aircraft types, while the State of Registry ensures the airworthiness of individual aircraft. In the case of AD/CESSNA 303/1, which affected Cessna T303, 1982 model aeroplanes, CASA assessed and subsequently cancelled the directive as the unsafe condition it addressed no longer existed, effective from 25 September 2008. This cancellation adheres to Australia’s obligations under the Convention on International Civil Aviation, and as such, did not require public consultation or a Regulatory Impact Statement. The AD was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in line with the legislative provisions.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia. The Act empowers the Governor-General to make regulations necessary for the safety of air navigation, and under regulation 39.001, the Civil Aviation Safety Authority (CASA) can issue ADs for specified types of aircraft or aeronautical products. These ADs are legislative instruments that serve to ensure the continuing airworthiness of aircraft in line with international standards, particularly as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Registry for an aircraft holds the primary responsibility for the ongoing airworthiness of the aircraft, while the State of Design is responsible for the type certification and must provide necessary information to ensure continuing airworthiness. In the case of AD/CESSNA 303/1, which affected Cessna T303, 1982 model aeroplanes, CASA assessed and subsequently cancelled the AD due to the resolution of the unsafe condition, effective from 25 September 2008. Given that this cancellation aligns with Australia's obligations under international aviation conventions, no public consultation or regulatory impact statement was required.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to establish regulations that ensure the safety of air navigation. These regulations are intended to govern the operation and safety standards within the civil aviation sector. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are a form of legislative instrument, as outlined in section 46A of the Acts Interpretation Act 1901, and are considered disallowable instruments as per subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998. This means they are subject to parliamentary scrutiny and potential disallowance. Furthermore, ADs are recognised under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type to the appropriate States of Registry.
The obligations imposed by these provisions primarily fall on CASA, which is responsible for issuing and managing airworthiness directives. The State of Design has the responsibility to ensure the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry. The State of Registry, in turn, must develop or adopt requirements to maintain the continuing airworthiness of individual aircraft. These obligations are crucial for maintaining safety standards and ensuring compliance with international aviation safety protocols. CASA’s role in assessing and issuing ADs, such as the cancellation of AD/CESSNA 303/1 for Cessna T303, 1982 model aeroplanes, is part of its duty to oversee and manage these safety standards effectively.
There are no specific offences or penalties outlined in the Civil Aviation Safety Regulations 1998 concerning the issuance or non-compliance with airworthiness directives. However, the overarching framework of the Civil Aviation Act 1988 and related regulations imply that failure to comply with an AD could lead to severe consequences, including the potential grounding of an aircraft, legal action, or other regulatory sanctions. The cancellation of AD/CESSNA 303/1 is an example of CASA exercising its regulatory powers to ensure that unsafe conditions are addressed and rectified. While the specific AD in question has been cancelled without public consultation or a Regulatory Impact Statement, this does not necessarily indicate a lack of oversight. Instead, it reflects a procedural decision based on the international obligations under the Convention on International Civil Aviation, which take precedence in such matters. The AD was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, in accordance with subsection 84A(2) of the Act, demonstrating the structured and regulated process governing these safety directives.
