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 2009-19-04 affecting certain McCauley propellers. The USA is the State of Design for this equipment. CASA has assessed this AD and has issued Australian AD/PMC/53, which will become effective on 27 October 2009.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager Initial Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted by the Commonwealth Parliament to provide a legislative framework for the regulation of civil aviation in Australia, focusing on the safety and efficiency of air navigation. This legislation was introduced to address the need for a cohesive regulatory structure governing the civil aviation industry, ensuring it meets national and international safety standards. Section 98 of the Act empowers the Governor-General to make regulations that align with the Act's safety objectives, facilitating the implementation of necessary safety measures. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs), which serve as a key mechanism for maintaining the continuing airworthiness of aircraft and aeronautical products. This regulatory approach ensures that Australian aviation standards are consistent with international obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998 under the Civil Aviation Act 1988, specifically regulation 39.001, authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments under section 46A of the Acts Interpretation Act 1901 and are governed by the Legislative Instruments Act 2003. The ADs are issued to ensure the continuing airworthiness of aircraft, a responsibility that rests with the State of Registry, in accordance with Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is mandated to assess information provided by the State of Design and, if necessary, issue corresponding Australian ADs. For example, following the US Federal Aviation Administration’s issuance of AD 2009-19-04 concerning certain McCauley propellers, CASA has issued Australian AD/PMC/53, which became effective on 27 October 2009. Given the international obligations under the Convention on International Civil Aviation and the direct response to a State of Design directive, no public consultation was required, and the Office of Best Practice Regulation has determined that such ADs do not necessitate a Regulatory Impact Statement.
Key Provisions
The primary sections relevant to the issue of airworthiness directives (ADs) are section 98 of the Civil Aviation Act 1988 and regulation 39.001 of the Civil Aviation Safety Regulations 1998. Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, which includes the issuance of ADs through regulation 39.001. The ADs are considered legislative instruments, as they are disallowable instruments under section 46A of the Acts Interpretation Act 1901 and regulated by the Legislative Instruments Act 2003.
Under these provisions, the Civil Aviation Safety Authority (CASA) is tasked with the responsibility of issuing ADs for specific types of aircraft or aeronautical products to ensure compliance with airworthiness standards. 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 aircraft types. The State of Registry, in this case CASA for Australia, must then assess this information and, if necessary, issue a corresponding Australian AD to mandate the requirements of the State of Design.
Compliance with these regulations imposes significant obligations on CASA and the entities it governs. CASA must thoroughly assess any ADs issued by the State of Design and determine if they need to be adopted and enforced within Australia. This includes evaluating the safety implications of the AD and ensuring that the AD aligns with Australian aviation safety standards. For aircraft operators, compliance with ADs is mandatory. Failure to adhere to the requirements set out in an AD can result in severe consequences, including potential grounding of aircraft and other enforcement actions by CASA.
The Act also outlines specific consequences for non-compliance with ADs. Civil and criminal penalties may be imposed for breaches of ADs, reflecting the serious nature of ensuring air safety. While the specific penalties are not detailed in the provided text, the enforcement of ADs is a critical aspect of maintaining aviation safety standards. The implications of non-compliance can extend to significant financial penalties and, in severe cases, criminal charges against individuals or entities responsible for the oversight of the aircraft. The strict enforcement of ADs underscores the importance of adhering to these safety regulations.
