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 36/3 affecting Beechcraft 36 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 36/3. The cancellation will become effective on 8 May 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 Acting 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 a comprehensive legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. In this context, the Civil Aviation Safety Regulations 1998 were introduced to support the Act by providing detailed provisions on various aspects of civil aviation safety, including the issuance of airworthiness directives (ADs). Regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, establishing mandatory requirements to maintain the airworthiness of these aircraft. The policy objective of these regulations is to align with Australia's international obligations under the Convention on International Civil Aviation, particularly those outlined in Annex 8, which assigns responsibilities for the continuing airworthiness of aircraft to the State of Design and State of Registry. CASA, as Australia’s national airworthiness authority, is tasked with assessing and, if necessary, issuing Australian ADs based on information provided by the State of Design. This legislative framework ensures that the continuing airworthiness of aircraft registered in Australia is maintained in accordance with international standards.
Scope and Application
The Civil Aviation Act 1988 applies to the regulation of civil aviation in Australia and authorises the Governor-General to make regulations that ensure the safety of air navigation. Pursuant to this authority, the Civil Aviation Safety Regulations 1998 permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs, which are considered legislative instruments, serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft and ensuring compliance with safety standards. The ADs are issued in accordance with international obligations under the Convention on International Civil Aviation and are designed to address unsafe conditions identified by the State of Design. The ADs apply to aircraft registered within Australia, and CASA, as the national airworthiness authority, is responsible for assessing and issuing Australian ADs based on information provided by the State of Design. The ADs are enforceable and binding, and their issuance does not typically require public consultation or a Regulatory Impact Statement. The authority to issue and cancel ADs is vested in CASA, with the specific cancellation of AD/BEECH 36/3 being executed by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, in line with the provisions of the Civil Aviation Act 1988.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 (CASR) focus on the issuance of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations that ensure the safety of air navigation, while regulation 39.001 of the CASR specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) states that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, meaning it is a legislative instrument. The issuance of these ADs is essential for maintaining the airworthiness of aircraft and ensuring safety in air navigation.
The obligations and requirements imposed by the Act and the CASR on the parties or entities they govern are stringent. According to Annex 8 to the Convention on International Civil Aviation, the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure this airworthiness. The State of Registry, which in this context is Australia, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. CASA, acting as Australia's national airworthiness authority, is required to assess information from the State of Design and issue Australian ADs if necessary to mandate the requirements of the State of Design. This ensures that Australian-registered aircraft meet international safety standards.
Breach of the obligations and requirements under the Civil Aviation Act 1988 and the CASR can lead to significant legal consequences. Although specific offences and penalties are not detailed in the provided text, it is understood that non-compliance with ADs can result in severe civil or criminal penalties. Such penalties may include fines or imprisonment, depending on the severity and impact of the non-compliance on aviation safety. The cancellation of AD/BEECH 36/3 serves as an example where CASA has taken regulatory action to ensure that an unsafe condition is addressed and rectified, highlighting the importance of adhering to ADs to maintain the safety and airworthiness of aircraft.
