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/BEA 206/3 affecting Beagle B206 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/BEA 206/3. The cancellation will become effective on
2 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, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, establishes the legal framework for ensuring the safety and efficiency of civil aviation within Australia. The Act empowers the Governor-General to make regulations aimed at safeguarding air navigation, reflecting a policy objective to maintain high standards of aviation safety. One such regulation, specified in the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These directives, which are considered legislative instruments under the Legislative Instruments Act 2003, are essential for ensuring the continuing airworthiness of aircraft in accordance with international standards set by the Convention on International Civil Aviation. The cancellation of Australian AD/BEA 206/3, affecting Beagle B206 series aeroplanes, exemplifies the application of these provisions to address specific safety issues, demonstrating CASA’s commitment to fulfilling its responsibilities under both national and international frameworks.
Scope and Application
The Civil Aviation Act 1988 applies to all aircraft operating in Australian airspace and to the Civil Aviation Safety Authority (CASA), which is Australia's national airworthiness authority. The Act empowers CASA to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998, ensuring compliance with safety standards and obligations under the Convention on International Civil Aviation. ADs are legislative instruments issued to mandate requirements for the continuing airworthiness of specific types of aircraft or aeronautical products. The scope of these directives includes all aircraft registered in Australia and must be assessed and, if necessary, adopted from the State of Design. In the case of AD/BEA 206/3, which affected Beagle B206 series aeroplanes, CASA cancelled the Australian AD due to the resolution of the unsafe condition, demonstrating the dynamic nature of airworthiness management in response to international obligations and safety assessments.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish a framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the Act’s purposes, which includes 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 specified kinds of aircraft or aeronautical products. These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and legislative instruments under section 6 of the Legislative Instruments Act 2003. ADs are essential tools for maintaining the continuing airworthiness of aircraft, and they are commonly issued by International Civil Aviation Organization (ICAO) Contracting States, including Australia.
Under these regulations, the State of Design of an aircraft bears the primary responsibility for ensuring the aircraft's continuing airworthiness, as per Annex 8 to the Convention on International Civil Aviation. This responsibility includes providing necessary information to the State of Registry, which is the State responsible for an individual aircraft's airworthiness. When an AD is issued by a State of Design for a type of aircraft registered in Australia, CASA must evaluate the information and, if appropriate, issue an Australian AD to enforce the requirements specified by the State of Design. This ensures that Australian-registered aircraft meet international safety standards.
CASA, acting on behalf of Australia, has issued and subsequently cancelled Australian AD/BEA 206/3, which affected Beagle B206 series aeroplanes. This cancellation, effective from 2 July 2009, was made because the unsafe condition that necessitated the AD no longer exists. As a result, no replacement AD is required. This action aligns with Australia’s obligations under the Convention on International Civil Aviation, and therefore, no public consultation or Regulatory Impact Statement was necessary.
Failure to comply with ADs can lead to serious consequences. CASA, as the national airworthiness authority, enforces these directives to ensure compliance. Non-compliance with an AD may result in the grounding of an aircraft, legal action against the aircraft operator, and potential civil or criminal penalties. While the specific penalties for non-compliance with ADs are not detailed in the provided text, they generally include fines and other enforcement measures to ensure the safety of air navigation is upheld.
