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.
CASA issued AD/AC/47, affecting Aerocommander model aircraft in 1972. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Airframes 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 Parliament of Australia, addresses the regulation and safety of civil aviation within Australia, including the issuance of airworthiness directives to ensure the safety of aircraft. Pursuant to this Act, the Civil Aviation Safety Regulations 1998 were also established to provide detailed rules and requirements for maintaining the airworthiness of aircraft and aeronautical products. One critical aspect of these regulations is the ability of the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products, as outlined in regulation 39.001. This process ensures that the continuing airworthiness of aircraft is maintained, in line with the international standards set by the Convention on International Civil Aviation. The issuing of these directives is a legislative instrument, subject to disallowance and review as stipulated in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The policy objective is to uphold the highest safety standards in air navigation, thereby protecting the public and promoting the responsible management of airworthiness.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for issuing airworthiness directives (ADs) in Australia, with the overarching aim of ensuring the safety of air navigation. Under section 98 of the Act, the Governor-General has the authority to create regulations in the interests of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under the Acts Interpretation Act 1901 and are legislative instruments as per the Legislative Instruments Act 2003. The ADs are a reflection of international standards, as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design bears the responsibility for the continuing airworthiness of an aircraft type. The State of Registry, which in Australia is CASA, must then ensure the continuing airworthiness of aircraft registered within its jurisdiction. The cancellation of an AD, such as AD/AC/47 affecting Aerocommander model aircraft issued by CASA in 1972, is conducted under the authority of the Act and is subject to review and assessment by CASA. The decision to cancel such an AD is made to reduce the regulatory burden and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 provides the legislative framework for the safety of air navigation in Australia, with particular attention to the airworthiness of aircraft and aeronautical products. Section 98 of this Act empowers the Governor-General to create regulations that align with the Act's objectives, ensuring safety in air navigation. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are intended to address any identified safety issues and are considered legislative instruments under the Legislative Instruments Act 2003.
Airworthiness directives are a crucial mechanism for maintaining the safety standards of aircraft. Under Annex 8 of the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry must ensure the ongoing airworthiness of individual aircraft. Consequently, when CASA, as Australia’s national airworthiness authority, receives an AD from a State of Design, it must assess the information and, if necessary, issue an Australian AD to enforce the State of Design's requirements. This collaborative approach ensures that all aircraft in Australia meet the highest safety standards.
The obligations under the Civil Aviation Safety Regulations 1998 require CASA to carefully consider any ADs issued by the State of Design and to act promptly to issue corresponding Australian ADs when necessary. This process involves rigorous assessment to ensure that the safety measures outlined in the AD are appropriate and effectively address any identified risks. Additionally, CASA must ensure that these ADs are communicated effectively to all relevant parties, including aircraft operators, maintenance providers, and other stakeholders. The process must also comply with the requirements set out in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Breaching the obligations imposed by the Civil Aviation Safety Regulations 1998 can result in significant consequences. Failure to comply with an airworthiness directive can lead to serious safety risks, potentially resulting in accidents or incidents. The Civil Aviation Act 1988 provides for both civil and criminal penalties for non-compliance with ADs. Civil penalties can include fines and other monetary sanctions, while criminal penalties may involve imprisonment. The specific penalties depend on the severity of the breach and the circumstances surrounding it, reflecting the critical importance of adhering to safety regulations in the aviation industry.
