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/BEECH 90/33 affecting Beechcraft E90 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 90/33. The cancellation will become effective on 3 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, 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 was enacted to provide for the regulation of civil aviation in Australia, addressing the need for comprehensive safety standards and procedures in the aviation industry. The Act empowers the Governor-General to make regulations that promote the safety of air navigation. In accordance with section 98 of the Act, the Civil Aviation Safety Regulations 1998 were introduced to further specify safety requirements, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are legislative instruments that mandate specific safety measures for aircraft or aeronautical products, ensuring compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, has the responsibility to issue and manage these directives to maintain the continuing airworthiness of aircraft registered in Australia. The process ensures that Australia meets its international obligations while maintaining stringent safety standards within its jurisdiction.
Scope and Application
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, facilitates the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. These ADs, which serve as the primary means of ensuring the continuing airworthiness of aircraft, are issued by the State of Design and adopted or developed by the State of Registry. In Australia, CASA, as the national airworthiness authority, is responsible for assessing international ADs and issuing Australian ADs when necessary. The AD/BEECH 90/33, which was issued for the Beechcraft E90 model aircraft, has been cancelled by CASA effective 3 July 2008, as the unsafe condition it was addressing no longer exists. This cancellation aligns with Australia’s obligations under the Convention on International Civil Aviation, and the process did not require public consultation or a Regulatory Impact Statement. The Manager, Systems and New Technologies in the Airworthiness Engineering Branch of CASA made this AD cancellation in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations to ensure the safety of air navigation. 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. According to subregulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and consequently, an AD is a legislative instrument as per section 6 of the Legislative Instruments Act 2003. These directives are a crucial form of communication under Annex 8 of the Convention on International Civil Aviation, whereby the State of Design has overarching responsibility for the continuing airworthiness of an aircraft type, and must share necessary information with States of Registry to ensure safety.
The obligations imposed by the Act and the Regulations require the State of Design to provide necessary information for maintaining airworthiness, while the State of Registry must implement or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. Specifically, when the State of Design issues an AD for a type of aircraft registered in Australia, CASA must review this information and, if deemed necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that all aircraft in Australia meet the necessary safety standards as dictated by international conventions.
Failure to comply with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in significant consequences. While the specific offences and penalties are not detailed within the provided text, it is clear that non-compliance with airworthiness directives could lead to safety risks, potentially resulting in severe legal repercussions. Given the critical nature of air safety, penalties for breaches could include fines, imprisonment, or both, depending on the severity and impact of the non-compliance. The exact penalties would be determined by the relevant authorities and would align with the legal frameworks governing civil aviation in Australia.
