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 French DGAC has issued AD 96-054-078(B)R2 affecting Airbus A321 model aircraft. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A320/221, 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 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, aiming to ensure safety and efficiency in air navigation. Under this Act, the Governor-General has the authority to make regulations necessary for the safety of air navigation, and one of these regulations pertains to the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). This legislative mechanism allows CASA to mandate specific requirements for the continuing airworthiness of aircraft registered in Australia, aligning with international standards set by the Convention on International Civil Aviation. This approach ensures that Australian civil aviation practices are consistent with global safety norms, thereby addressing potential gaps in airworthiness compliance that could arise from the international nature of aircraft operations.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework within which the Civil Aviation Safety Authority (CASA) issues airworthiness directives (ADs) for aircraft and aeronautical products. Specifically, section 39.001 of the Regulations empowers CASA to issue ADs, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. ADs are critical for ensuring the continuing airworthiness of aircraft, with the State of Design having the primary responsibility for issuing such directives. In Australia, CASA, as the national airworthiness authority, is mandated to assess and, if necessary, issue Australian ADs to enforce the requirements set forth by the State of Design. This process ensures compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. For instance, following the issuance of a French AD concerning Airbus A321 aircraft, CASA assessed and subsequently issued an Australian AD to mandate the same safety measures. These directives apply to all aircraft registered within Australia and are issued without public consultation, as they are based on international obligations and assessments by the relevant State of Design.
Key Provisions
The Civil Aviation Act 1988 (sections 98 and 84A) empowers the Governor-General to establish regulations that serve the Act's objectives and the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. In this context, an AD is a formal instruction issued to ensure that aircraft remain in a condition suitable for safe operation.
The obligations imposed by these regulations primarily rest on CASA as Australia's national airworthiness authority. CASA must assess ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to ensure compliance with the State of Design's requirements. For example, the French Civil Aviation Authority (DGAC) has issued AD 96-054-078(B)R2 concerning Airbus A321 aircraft, a type designed in France. CASA has evaluated this AD and issued Australian AD/A320/221, effective from 5 June 2008. This process underscores CASA's role in enforcing continuing airworthiness standards for aircraft registered in Australia.
The Civil Aviation Safety Regulations 1998 also outline the State of Registry's responsibilities for an aircraft's continuing airworthiness. Under Annex 8 to the Convention on International Civil Aviation, the State of Registry must establish or adopt measures to ensure that aircraft remain airworthy. For instance, when the State of Design issues an AD, the State of Registry must evaluate and, if appropriate, implement corresponding measures. This ensures that all stakeholders, including aircraft operators and maintenance providers, adhere to the necessary safety standards.
Failure to comply with the ADs and the associated regulations can result in serious consequences. While the specific offences and penalties are not detailed in the provided text, non-compliance with ADs can lead to enforcement actions under the Civil Aviation Act 1988. These actions may include fines, suspension or revocation of airworthiness certificates, or other regulatory measures. Such consequences underscore the importance of adhering to ADs to maintain aviation safety standards.
