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/CHA/7 affecting Bellanca model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CHA/7. The cancellation will become effective on 7 May 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, is the primary legislative framework governing civil aviation safety in Australia. It provides the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs) to ensure the continuing airworthiness of aircraft registered in Australia. These directives are issued under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows CASA to mandate specific actions to maintain safety standards. The policy objective underpinning this legislation is to align with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type. CASA, as the national airworthiness authority, acts on the directives issued by the State of Design and ensures that these are appropriately reflected in Australian regulations. This legislative mechanism is crucial for harmonising safety practices across jurisdictions and maintaining high standards of airworthiness for aircraft operating within Australian airspace.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). This legislation applies to entities and individuals involved in the design, manufacture, maintenance, and operation of aircraft within Australia. The ADs are intended to ensure the continuing airworthiness of aircraft, aligning with the responsibilities of both the State of Design and the State of Registry as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is tasked with assessing ADs issued by other states and, if deemed necessary, issuing corresponding Australian ADs to enforce compliance. The regulations permit the issuance of these directives to mandate specific safety measures and requirements, thereby ensuring that all aircraft registered in Australia meet safety standards. The ADs are considered legislative instruments and can be subject to disallowance under the Acts Interpretation Act 1901. Additionally, CASA has the authority to cancel ADs when the unsafe conditions they were addressing no longer exist, as evidenced by the cancellation of AD/CHA/7 for Bellanca model aeroplanes, which was carried out in compliance with the Act’s provisions.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 that are relevant to the issue of airworthiness directives (ADs) include section 98 of the Act, which empowers the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Regulations, which allows the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. Section 39.001(5) of the Regulations specifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore a legislative instrument under section 6 of the Legislative Instruments Act 2003. This means that ADs are formal documents with legal force that can be issued to ensure the safety and airworthiness of aircraft.
The obligations and requirements imposed by these provisions on parties and entities include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type and to provide necessary information to appropriate States of Registry. The State of Registry, in this case CASA, has the responsibility to assess information provided by the State of Design and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. This ensures that Australian-registered aircraft meet international safety standards and comply with local regulations.
Under these regulations, there are significant consequences for breaches or non-compliance with ADs. Failure to adhere to an AD can result in serious safety issues and legal repercussions. While the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 do not explicitly state specific offences or penalties for non-compliance with ADs, breaches of aviation safety regulations generally can lead to civil or criminal penalties. For instance, non-compliance with ADs could result in fines, imprisonment, or both, depending on the severity of the breach and the discretion of the court. Additionally, operators and owners of aircraft found to be non-compliant may face suspension or revocation of their aircraft certificates of airworthiness, which can prevent the aircraft from legally operating.
The legislative framework ensures that airworthiness directives are a critical tool in maintaining the safety of air navigation, and that there are clear obligations and consequences for those who must comply with them. The regulations underscore the importance of international cooperation and adherence to safety standards in civil aviation.
