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 2008-02-13 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/B727/208, which will become effective on 10 April 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 Commonwealth Parliament, provides the legislative framework for ensuring the safety of air navigation in Australia. Under this Act, the Civil Aviation Safety Regulations 1998 were also established, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to mandate safety requirements for specific types of aircraft or aeronautical products. These regulations align with international obligations under Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as having overall responsibility for the continuing airworthiness of an aircraft type. In accordance with these international standards, CASA, as Australia's national airworthiness authority, must assess and, if necessary, issue Australian ADs to ensure compliance with the safety standards set by the State of Design. This legislative process underscores Australia's commitment to maintaining high safety standards in civil aviation, reflecting a policy objective of harmonising national regulations with international safety protocols.
Scope and Application
The Civil Aviation Act 1988 and its accompanying Civil Aviation Safety Regulations 1998 establish the framework within which airworthiness directives (ADs) are issued in Australia. These regulations apply to aircraft and aeronautical products, extending the scope to include any aircraft or aeronautical products that are registered within Australia. The Act and the associated regulations are applicable on a national scale, governed by the Commonwealth. The State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must ensure that individual aircraft maintain their airworthiness. In practice, when the State of Design issues an AD for a type of aircraft registered in Australia, the Civil Aviation Safety Authority (CASA) must assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. The issuance of these ADs is conducted under the authority granted by the Civil Aviation Act and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The ADs are legislative instruments that extend the application of the Act and are issued by authorised personnel within CASA.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are pivotal in establishing the framework for the issuance and enforcement of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to enact regulations that ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998, in turn, authorises the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) clarifies that an AD is a disallowable instrument, thereby rendering it a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are primarily centred around ensuring the safety and airworthiness of aircraft. The State of Design, which is the country where the aircraft type is designed, has the overarching responsibility for the continuing airworthiness of the aircraft type. This includes providing necessary information to the State of Registry to maintain the airworthiness of the aircraft. The State of Registry, typically the country where the aircraft is registered, must establish or adopt requirements to ensure that the aircraft remain airworthy. CASA, as Australia's national airworthiness authority, has the obligation to assess information from the State of Design and, if necessary, issue an Australian AD to enforce the requirements set forth by the State of Design. This ensures alignment with international safety standards and protocols.
Failure to comply with the requirements set out in an airworthiness directive can lead to significant consequences. The Civil Aviation Safety Regulations 1998 do not explicitly outline the penalties for non-compliance with ADs, but the overarching Civil Aviation Act 1988 provides a framework for enforcement. Non-compliance can potentially lead to serious safety issues, and in severe cases, it might result in the grounding of aircraft or other punitive measures. Although the specific penalties are not detailed in the Civil Aviation Safety Regulations 1998, they can include substantial fines and legal action against the operators or owners of non-compliant aircraft. The regulatory framework ensures that adherence to ADs is rigorously enforced to maintain the highest standards of aviation safety.
