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/BEECH 90/25, affecting Beech 90 model aircraft in 1971. 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 Australian Parliament, establishes the framework for ensuring the safety and efficiency of civil aviation in Australia. It empowers the Governor-General to make regulations aimed at enhancing the safety of air navigation. One such regulation is the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. The policy objective of this Act and its regulations is to ensure the highest safety standards in civil aviation through continuous airworthiness oversight and the issuance of necessary directives.
The Civil Aviation Act 1988 and its associated regulations are designed to align with international standards set by the Convention on International Civil Aviation, particularly through Annex 8, which mandates that the State of Design is responsible for the continuing airworthiness of an aircraft type. CASA, acting as Australia's national airworthiness authority, must assess any ADs issued by the State of Design and, if deemed necessary, issue corresponding ADs for aircraft registered in Australia. The process ensures that all aircraft maintain their airworthiness standards, thereby safeguarding public safety and international aviation compliance.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This regulatory framework is designed to ensure the continuing airworthiness of aircraft, a responsibility ultimately held by the State of Registry. In the case of Australia, CASA acts as the national airworthiness authority, required to assess and, if necessary, mandate the requirements of ADs issued by the State of Design. An AD is considered a legislative instrument, subject to disallowance under the Acts Interpretation Act 1901 and regulated by the Legislative Instruments Act 2003. The issuance of ADs aligns with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. For instance, CASA issued AD/BEECH 90/25 for Beech 90 model aircraft in 1971, which has since been cancelled due to the condition being addressed by another AD. The cancellation of this specific AD does not require public consultation as it reduces regulatory burden, and no Regulatory Impact Statement is mandated by the Office of Best Practice Regulation. The AD was made by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in compliance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 lay out a framework for ensuring the safety of air navigation. Specifically, section 98 of the Act empowers the Governor-General to create regulations in the interest of air navigation safety, while regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain aircraft or aeronautical products. This regulatory power is further clarified by subregulation 39.001(5), which states that an AD is a disallowable instrument under the Acts Interpretation Act 1901 and a legislative instrument under the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant. The State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to ensure the continuing airworthiness of the aircraft type to the appropriate States of Registry. Meanwhile, the State of Registry is tasked with developing or adopting requirements to ensure the continuing airworthiness of aircraft. In the case of Australia, CASA, as the national airworthiness authority, must assess any ADs issued by the State of Design and, if necessary, issue an Australian AD to enforce the requirements of the State of Design.
The Act and Regulations also impose consequences for non-compliance. While the specific offences and penalties are not detailed in the provided text, it is clear that regulatory oversight is stringent, with CASA having the authority to issue ADs and enforce compliance. The Civil Aviation Safety Regulations 1998 provide a robust framework for ensuring that aircraft remain airworthy and safe for operation. The text does not specify the maximum penalties for non-compliance, but it is reasonable to infer that significant penalties could apply, given the critical nature of aviation safety regulations.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive regulatory framework for ensuring the safety of air navigation in Australia. CASA’s role in issuing and enforcing ADs is central to this framework, with obligations clearly defined for both the State of Design and the State of Registry. The consequences for non-compliance are significant, reflecting the high stakes involved in aviation safety.
