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 UF-2005-117 affecting Airbus A320 model aircraft. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A320/181, which will become effective on 1 September 2005.
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 legal framework governing civil aviation activities in Australia. This Act empowers the Governor-General to make regulations that are integral to the safety of air navigation, and it has been instrumental in facilitating Australia's compliance with international aviation standards. One of the key provisions of the Act is the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. ADs are legislative instruments used to mandate safety requirements for specific types of aircraft or aeronautical products. The issuance of ADs is a critical mechanism for maintaining the continuing airworthiness of aircraft, as per the requirements of Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has the overall responsibility for the continuing airworthiness of an aircraft type. CASA, acting as Australia’s national airworthiness authority, is required to issue corresponding ADs when a State of Design issues a directive that affects aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988 and the associated Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation, and one significant aspect of this framework is the issuance of airworthiness directives (ADs). Under this legislation, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products, as outlined in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments that mandate specific safety requirements to ensure the continuing airworthiness of aircraft, and they are issued in response to obligations under international agreements such as the Convention on International Civil Aviation. ADs are typically issued by the State of Design, and CASA, as Australia's national airworthiness authority, is responsible for assessing these directives and, if necessary, issuing corresponding Australian ADs. This process ensures that aircraft registered in Australia comply with international safety standards. The issuance of ADs under this legislation does not require consultation with the public or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The ADs are crafted in accordance with the Act and are a crucial mechanism for maintaining the safety and airworthiness of aircraft within Australia.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to create regulations that safeguard air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs are legislative instruments, as stipulated under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. They are crucial for maintaining the continuing airworthiness of aircraft, as per Annex 8 of the Convention on International Civil Aviation.
Under these regulations, the State of Design—the country responsible for designing the aircraft—bears the overall responsibility for the aircraft type's continuing airworthiness and must provide necessary information to the States of Registry. These States of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft on their registers. When a State of Design issues an AD, CASA must assess the information and, if necessary, issue an Australian AD to mandate the State of Design's requirements. For instance, the French Civil Aviation Authority (DGAC) issued AD UF-2005-117 concerning Airbus A320 model aircraft, and CASA subsequently issued Australian AD/A320/181, effective from 1 September 2005.
CASA is obligated to assess ADs issued by the States of Design and, if necessary, issue corresponding Australian ADs to ensure compliance with international standards and obligations under the Convention on International Civil Aviation. This process ensures that Australian aircraft meet the required safety standards and are airworthy. Furthermore, the Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement, and no public consultation is mandated for these directives. The AD is 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.
Failure to comply with the requirements set out in an airworthiness directive can result in severe consequences. Non-compliance may lead to the aircraft being grounded, which can have significant operational and financial implications for operators. In addition, CASA has the authority to take enforcement actions against non-compliant aircraft or operators. Penalties for breaches can include fines, suspension of the aircraft's airworthiness certificate, and other administrative measures. In severe cases, criminal charges may be pursued, leading to imprisonment for the responsible individuals or entities. These stringent measures underscore the importance of adhering to ADs to maintain the highest safety standards in aviation.
