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/AC/16 affecting all Twin Aero Commander aircraft models. CASA has assessed this AD and as a result has cancelled Australian AD/AC/16. The cancellation will become effective on 31 July 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, Airframe and Structures, 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 establish and regulate the safety of civil aviation in Australia. This legislation was introduced to address the need for comprehensive regulation of air navigation and aircraft safety, ensuring that these activities are conducted in a manner that protects the public and promotes efficient air travel. The Act empowers the Governor-General to make regulations for the purposes of the Act, as seen in the Civil Aviation Safety Regulations 1998. The Civil Aviation Safety Regulations 1998 further provide the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, aligning with international standards and obligations under the Convention on International Civil Aviation. This regulatory framework ensures that Australia meets its commitments to international safety standards while maintaining the safety of air navigation within its jurisdiction.
Scope and Application
The Civil Aviation Act 1988 applies to any person, entity, aircraft, aeronautical product, or transaction that falls within the scope of civil aviation in Australia. Under the Act, the Governor-General has the authority to make regulations that promote the safety of air navigation, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The ADs are legislative instruments that mandate safety requirements for specific kinds of aircraft or aeronautical products to ensure their continuing airworthiness. This Act applies nationally across Australia, adhering to international standards set by the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 further specify the process and authority for CASA to issue ADs, which must be assessed and, if appropriate, adopted by Australia. The ADs are not subject to disallowance, and their cancellation or issuance does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The ADs are issued by authorised personnel within CASA, ensuring compliance with both national and international aviation safety standards.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance and management of airworthiness directives (ADs) in Australia. According to section 98 of the Act, the Governor-General has the authority to make regulations that contribute to the safety of air navigation, and regulation 39.001 of the Regulations specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are considered legislative instruments under section 46A of the Acts Interpretation Act 1901 and are subject to disallowance.
The obligations imposed by the Civil Aviation Act and Regulations on parties and entities primarily concern the maintenance of airworthiness. Under Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry must ensure the airworthiness of individual aircraft. CASA, as Australia’s national airworthiness authority, must evaluate ADs issued by States of Design and, if necessary, issue corresponding Australian ADs. This ensures that Australian aircraft comply with international standards and safety requirements.
Failure to comply with ADs can result in serious consequences. While the Civil Aviation Safety Regulations do not explicitly outline specific offences or penalties for non-compliance with ADs, general provisions of the Civil Aviation Act 1988 and other related legislation may apply. Non-compliance with ADs can lead to the grounding of affected aircraft, which can result in significant financial losses and potential safety risks. Furthermore, CASA may take enforcement actions against non-compliant operators, which could include fines, suspension or revocation of air operator certificates, and other regulatory measures. The exact penalties depend on the severity of the breach and the specific circumstances of the case.
