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 56/15 affecting Beechcraft 56TC and A56TC model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 56/15. The cancellation will become effective on 5 June 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 establish 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 make regulations that promote air navigation safety, which include the issuance of airworthiness directives (ADs) as stipulated in the Civil Aviation Safety Regulations 1998. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products to maintain their airworthiness. The ADs are legislative instruments and must comply with the requirements of the Legislative Instruments Act 2003. The cancellation of a particular AD, such as AD/BEECH 56/15, reflects Australia's adherence to the Convention on International Civil Aviation, where the State of Design has the responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, assesses these directives and issues corresponding Australian ADs when necessary. This process underscores the collaborative international approach to aviation safety, ensuring that Australia meets its international obligations while maintaining high safety standards domestically.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, encompasses the regulatory framework governing airworthiness directives (ADs) in Australia. Under this framework, the Civil Aviation Safety Authority (CASA), as the national airworthiness authority, is empowered to issue ADs to ensure the safety of aircraft within Australia’s jurisdiction. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to issue these directives for specific kinds of aircraft or aeronautical products. These directives are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and are crafted in accordance with the international standards set by Annex 8 to the Convention on International Civil Aviation. ADs serve as crucial tools for maintaining the continuing airworthiness of aircraft, with CASA responsible for issuing Australian ADs when required by the State of Design or in alignment with international obligations. The authority to issue and cancel such directives is exercised by CASA under the authority delegated by the Civil Aviation Act 1988, ensuring that the safety standards are consistently upheld across the Australian aviation sector.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, allows the Governor-General to establish regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as a legislative instrument under section 6 of the Legislative Instruments Act 2003 and are subject to disallowance under section 46A of the Acts Interpretation Act 1901.
Under the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to ensure it. The State of Registry, in this case, CASA, must assess this information and issue an Australian AD if necessary. This ensures that aircraft registered in Australia meet international safety standards. The Civil Aviation Safety Authority has issued and subsequently cancelled AD/BEECH 56/15 for Beechcraft 56TC and A56TC model aircraft, effective from 5 June 2008, as the unsafe condition no longer exists.
The obligations imposed on CASA under these provisions include the assessment and issuance of ADs when required, ensuring that all aircraft registered in Australia meet the continuing airworthiness standards. CASA must also monitor and respond to ADs issued by other ICAO Contracting States, reflecting Australia's commitment to international safety standards. CASA must act promptly in cancelling ADs when unsafe conditions are no longer present, ensuring that operational safety is maintained.
Failure to comply with the requirements of an AD can lead to serious consequences. If an operator does not comply with the mandates of an AD, they could face enforcement actions from CASA. In some cases, non-compliance can result in civil penalties, such as fines. For more serious breaches, CASA can suspend or revoke an aircraft's certificate of airworthiness, effectively grounding the aircraft until the issues are resolved. These actions are taken to enforce safety standards and protect the public from potential hazards.
