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 2008-08-02 affecting Boeing B727 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B727/211, which will become effective on 5 June 2008.
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, 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, serves as the foundational statute for the regulation of civil aviation within Australia, encompassing aspects such as safety, efficiency, and environmental protection. This Act empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. In particular, the Civil Aviation Safety Regulations 1998, pursuant to section 98 of the Civil Aviation Act 1988, authorise the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. This mechanism is critical for maintaining the continuing airworthiness of aircraft and ensuring compliance with international safety standards as set forth in the Convention on International Civil Aviation. The issuance of ADs, such as AD/B727/211 for Boeing B727 model aircraft, reflects Australia's commitment to aligning with international obligations and maintaining high safety standards in the national airspace.
Scope and Application
The Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, which are legislative instruments made to ensure the safety of air navigation. Under the Act, the Governor-General has the authority to make regulations, and under the Regulations, the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products. These ADs are mandated by the State of Design's responsibility to maintain the continuing airworthiness of aircraft types, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in this context is Australia, must ensure the ongoing airworthiness of aircraft registered within its jurisdiction. When a State of Design issues an AD, such as the US Federal Aviation Administration's AD 2008-08-02 for Boeing B727 model aircraft, CASA evaluates the information and issues a corresponding Australian AD, like AD/B727/211, to enforce the requirements within Australian-registered aircraft of that type. This process ensures compliance with international standards and does not involve public consultation or require a Regulatory Impact Statement, as it is driven by international obligations and the specific needs of aircraft safety.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to make regulations that contribute to the safety of air navigation, a principle that is central to the operations of the Civil Aviation Safety Regulations 1998. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These directives are crucial for ensuring that aircraft remain in a condition safe for operation and are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant for both CASA and the operators of the aircraft. CASA, as Australia’s national airworthiness authority, must carefully assess any ADs issued by the State of Design—the country where the aircraft was designed. For example, in the case of Boeing B727 model aircraft, CASA must review any ADs issued by the United States Federal Aviation Administration (FAA) and determine whether these should be adopted and implemented in Australia. If deemed necessary, CASA issues corresponding ADs for Australian-registered aircraft, ensuring compliance with international safety standards and Australia’s obligations under the Convention on International Civil Aviation.
Failure to comply with an airworthiness directive can result in severe consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to significant penalties. Civil penalties can include fines up to a substantial amount as specified in the Act, while criminal penalties may apply for more serious breaches, potentially resulting in imprisonment. The enforcement of these regulations is critical to maintaining the high standards of safety and reliability in air navigation, and the potential penalties serve as a deterrent against non-compliance.
Moreover, the legislative process for issuing these ADs is streamlined due to their nature and the international obligations that necessitate them. ADs, such as the one issued for Boeing B727 aircraft, do not require consultation with the Australian public or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This expediency allows for swift action to be taken in response to identified safety issues, ensuring that aircraft remain airworthy and safe for operation. The AD is issued by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988, which underscores the authority and responsibility vested in CASA to act in the best interest of aviation safety.
