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 US FAA has issued AD 2007-05-10 affecting Cessna 206 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/CESSNA 206/63, which will become effective on 11 April 2007.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to ensure the safety of air navigation and to provide a comprehensive legal framework governing civil aviation in Australia. This legislation was introduced to address the need for a robust regulatory structure to manage the complexities and risks associated with civil aviation, including aircraft registration, licensing, and airworthiness standards. The Act empowers the Governor-General to make regulations that serve the interests of safety in air navigation. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions by granting the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are legislative instruments that mandate compliance to ensure the continuing airworthiness of aircraft, aligning with Australia’s obligations under international conventions such as the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation, thereby applying to all persons and entities involved in the operation of aircraft registered in Australia. These regulations mandate that CASA, as Australia’s national airworthiness authority, assess and, if necessary, issue Australian ADs in response to ADs issued by the State of Design, such as the United States for certain aircraft types. This regulatory framework is essential for maintaining the continuing airworthiness of aircraft registered in Australia, ensuring compliance with international standards as set out in Annex 8 to the Convention on International Civil Aviation. Notably, ADs are legislative instruments, which can be subject to disallowance under the Acts Interpretation Act 1901, and are created in accordance with the provisions of the Legislative Instruments Act 2003. While ADs are integral to international cooperation in aviation safety, they are not subject to public consultation or Regulatory Impact Statements, reflecting their technical and safety-focused nature.
Key Provisions
The Civil Aviation Act 1988 provides the framework within which the Governor-General has the authority to create regulations aimed at ensuring the safety of air navigation (section 98). One of the key provisions of this Act is the ability for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs apply to specific types of aircraft or aeronautical products, and they are designed to maintain the continuing airworthiness of aircraft (39.001(5)). It is important to note that ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901 and governed by the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on the entities they govern are significant. The State of Design of an aircraft type, such as the USA for a Cessna 206, has the primary responsibility to ensure that the aircraft type remains airworthy. This responsibility includes providing any necessary information to the States of Registry to maintain this airworthiness. The State of Registry, in this case Australia, must implement measures to ensure that individual aircraft remain airworthy, either by developing or adopting appropriate requirements. When an AD is issued by a State of Design, CASA, as Australia’s national airworthiness authority, is obliged to review this information and, if necessary, issue a corresponding Australian AD. This ensures that the requirements of the State of Design are legally mandated in Australia.
Failure to comply with an AD can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD is an offence that can result in civil penalties. The specific maximum penalties for such breaches are not detailed in the provided text, but they can include substantial fines. Additionally, continued non-compliance or repeated offences could result in criminal charges. The potential civil and criminal repercussions serve as a deterrent to ensure that all stakeholders adhere to the safety standards set forth by the ADs, thereby maintaining the safety of air navigation.
