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/SM-260/5 affecting SIAI Marchetti 260 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/SM-260/5. The cancellation will become effective on 30 July 2009. 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, Airframe and Structures, 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 a legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. Under this Act, the Governor-General has the authority to create regulations that serve the interests of air navigation safety. 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 types of aircraft or aeronautical products, which are legislative instruments that can be disallowed under the Acts Interpretation Act 1901. These ADs are essential tools for maintaining the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. CASA, as the national airworthiness authority, is responsible for assessing and implementing ADs issued by the State of Design and ensuring compliance with these directives for aircraft registered in Australia. In this context, CASA issued and subsequently cancelled AD/SM-260/5 for SIAI Marchetti 260 series aeroplanes, reflecting Australia's commitment to international safety standards and the resolution of previously identified unsafe conditions.
Scope and Application
The Civil Aviation Act 1988, as amended, governs the regulation and safety of aviation in Australia. Under this Act, the Governor-General is empowered to make regulations to ensure the safety of air navigation. The Civil Aviation Safety Regulations 1998 implement this authority and permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby ensuring the ongoing safety standards of aircraft in Australia. These ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. The ADs align with international standards under Annex 8 to the Convention on International Civil Aviation, where the State of Design holds responsibility for the continuing airworthiness of an aircraft type, and the State of Registry, in this case CASA, ensures compliance with these standards within Australia. The application of these ADs is integral to maintaining the safety and airworthiness of aircraft registered in Australia, and their issuance and cancellation reflect Australia’s commitment to international aviation safety standards.
Key Provisions
The key operative sections of this legislation, particularly sections 98 and 39.001 of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, provide the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs). An AD is a legislative instrument that mandates specific requirements to ensure the continuing airworthiness of aircraft. In this instance, CASA has cancelled AD/SM-260/5, which affected SIAI Marchetti 260 series aeroplanes, as the unsafe condition it addressed no longer exists.
Entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, including CASA and aircraft operators, must comply with the ADs issued by CASA. Specifically, CASA has the responsibility to assess ADs issued by the State of Design and, when necessary, issue Australian ADs to enforce the requirements. Aircraft operators must adhere to the ADs applicable to their aircraft, ensuring they meet the safety standards set by CASA.
Failure to comply with ADs can result in significant legal consequences. For example, aircraft operators who do not adhere to an AD may face enforcement actions, including fines, suspension of their operator certificate, or even criminal charges in severe cases. While the specific penalties are not detailed in the provided text, the general principle is that non-compliance with ADs can lead to regulatory action and potential criminal liability.
It is noteworthy that the cancellation of AD/SM-260/5 was executed due to Australia’s international obligations under the Convention on International Civil Aviation, specifically Annex 8, and no public consultation was required as ADs are not considered to require a Regulatory Impact Statement. This cancellation reflects CASA’s adherence to international standards and obligations, ensuring that Australian regulations align with global safety frameworks.
