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 33/8 affecting Beech 33 type/model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 33/8. The cancellation will become effective on 10 April 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, enacted by the Commonwealth Parliament, addresses the need for regulations that ensure the safety of air navigation, delegating authority to the Governor-General to make such regulations. Complementing this, the Civil Aviation Safety Regulations 1998 provide for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), which are instrumental in maintaining the continuing airworthiness of aircraft as per Annex 8 to the Convention on International Civil Aviation. The ADs are legislative instruments that serve to mandate specific requirements for aircraft types registered in Australia, ensuring compliance with international standards for safety and airworthiness. The Act and regulations together facilitate the effective management of aircraft safety and airworthiness within Australia, reflecting the nation's commitment to international aviation safety standards.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes the framework for the regulation of airworthiness in Australia, with the overarching aim of ensuring the safety of air navigation. Under this legislative framework, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. The issuance and assessment of ADs are integral to Australia's compliance with international obligations under the Convention on International Civil Aviation, particularly Annex 8, which delineates the responsibilities of the State of Design and the State of Registry in ensuring the continuing airworthiness of aircraft types. CASA, as Australia’s national airworthiness authority, is tasked with evaluating international ADs and issuing corresponding Australian ADs when necessary. This process ensures that Australian aircraft maintain their airworthiness standards in alignment with international safety protocols.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to establish regulations that serve the Act's purposes, particularly focusing on the safety of air navigation. Under this authority, the Civil Aviation Safety Regulations 1998 (regulation 39.001) enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified aircraft types or aeronautical products. These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments according to section 6 of the Legislative Instruments Act 2003. The ADs issued by CASA must comply with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. This annex places the responsibility for an aircraft type's continuing airworthiness on the State of Design, requiring it to provide necessary information to the States of Registry to ensure safety.
The obligations placed on the State of Registry include developing or adopting specific requirements to maintain the continuing airworthiness of aircraft within their jurisdiction. When a State of Design issues an AD against a type of aircraft registered in Australia, CASA must review this information and, if necessary, issue an Australian AD to enforce the requirements. This process was followed in the case of AD/BEECH 33/8, which affected Beech 33 type/model aircraft. After evaluation, CASA cancelled AD/BEECH 33/8, effective from 10 April 2008, as the unsafe condition identified in the AD no longer existed, rendering a replacement AD unnecessary.
The cancellation of AD/BEECH 33/8 was executed under Australia's obligations under the Convention on International Civil Aviation, which obviated the need for public consultation on the AD cancellation. Additionally, the Office of Best Practice Regulation has determined that such ADs do not require a Regulatory Impact Statement. The AD was formally issued by the Acting Manager of Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act.
In terms of compliance, failure to adhere to ADs can result in significant consequences. Non-compliance with an AD can be considered an offence under the Civil Aviation Act 1988, leading to potential civil or criminal penalties. The severity of these penalties can vary, but they may include fines, imprisonment, or both, depending on the nature and extent of the breach. It is crucial for all relevant parties, including aircraft operators and maintenance providers, to comply strictly with ADs to ensure safety and avoid legal repercussions.
