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/FU24/41 affecting Airparts (NZ) FU24 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 was enacted to address the need for comprehensive regulation of civil aviation safety in Australia. It empowers the Governor-General to create regulations that ensure the safety of air navigation. The Civil Aviation Safety Regulations 1998, under section 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, which are considered legislative instruments under the Legislative Instruments Act 2003. These directives are essential for maintaining the continuing airworthiness of aircraft, a responsibility mandated by Annex 8 to the Convention on International Civil Aviation. CASA, as the national airworthiness authority, must evaluate information from the State of Design and, if necessary, issue Australian ADs to enforce the requirements of the State of Design. In line with these provisions, CASA has decided to cancel the AD/FU24/41 for Airparts (NZ) FU24 model aircraft from 1971, effective 17 January 2008, due to the resolution of the original safety issue by another directive, AD/GENERAL/74 Amendment 1. This cancellation, which reduces the regulatory burden, did not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Scope and Application
The Civil Aviation Safety Regulations 1998, as a legislative instrument under the Civil Aviation Act 1988, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products, thereby ensuring the safety of air navigation in Australia. These ADs are legally binding instruments aimed at maintaining the airworthiness of aircraft registered in Australia and are issued in response to safety concerns identified by the State of Design. The application of these regulations extends to all aircraft and aeronautical products within Australia's jurisdiction, ensuring compliance with international standards set by the Convention on International Civil Aviation. The ADs are instrumental in enforcing the continuing airworthiness requirements mandated by the State of Registry, with CASA playing a pivotal role in their issuance and enforcement. The cancellation of a particular AD, such as AD/FU24/41 affecting Airparts (NZ) FU24 model aircraft, is a process overseen by CASA, reflecting the dynamic nature of aviation safety regulations and the authority's commitment to adapting to new information and technological advancements.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 set out the framework for ensuring the safety and airworthiness of aircraft within Australia. Section 98 of the Act allows the Governor-General to create regulations in the interest of air navigation safety, and under regulation 39.001, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
These airworthiness directives play a crucial role in maintaining the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the initial airworthiness of a type of aircraft, must provide necessary information to ensure the ongoing safety of the aircraft to the State of Registry, which is responsible for the individual aircraft’s airworthiness. CASA, as Australia’s national airworthiness authority, must then evaluate this information and issue an Australian AD if appropriate, to enforce the State of Design’s requirements.
The obligations imposed by the Act and the Regulations on parties such as CASA and the State of Registry are significant. CASA must assess the ADs issued by the State of Design and decide whether to implement an Australian AD to ensure compliance with safety standards. The State of Registry, on the other hand, must develop or adopt requirements to ensure the ongoing airworthiness of aircraft within its jurisdiction. In cases where CASA cancels an existing AD, such as AD/FU24/41 affecting Airparts (NZ) FU24 model aircraft, it must ensure that the cancellation results in no adverse impact on safety, and that any necessary measures are in place to address previously identified issues.
There are also legal consequences for breaches of the regulations outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. While the specific penalties for non-compliance with ADs are not detailed in the provided text, it is reasonable to infer that failure to adhere to these directives could result in serious civil or criminal penalties. Such penalties might include fines, imprisonment, or other regulatory actions deemed necessary by CASA to enforce compliance and maintain aviation safety standards.
