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 European Aviation Safety Authority (EASA) has issued AD 2007-0034 affecting Socata TB 200 model aircraft. EASA acts on behalf of France, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/TB 200/10, which will become effective on 12 April 2007.
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 regulate the safety and efficiency of civil aviation in Australia, ensuring that air navigation safety is upheld. This legislation empowers the Governor-General to create regulations that serve the interests of air navigation safety. The Civil Aviation Safety Regulations 1998, which are made under the authority of the Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are considered legislative instruments as per the Legislative Instruments Act 2003 and serve as a mechanism for ensuring the continuing airworthiness of aircraft. The Act ensures that Australia adheres to international standards as outlined in the Convention on International Civil Aviation, particularly the responsibilities of the State of Design and State of Registry regarding aircraft airworthiness.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for issuing airworthiness directives (ADs) in Australia, facilitating the maintenance of aircraft safety standards in line with international obligations. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, which are legislative instruments under the Acts Interpretation Act 1901. The ADs are integral to the continuing airworthiness of aircraft, as per Annex 8 of the Convention on International Civil Aviation, with the State of Design holding primary responsibility for airworthiness information. The State of Registry, in this case CASA, must then assess and, if necessary, issue corresponding ADs to ensure compliance with international standards. For example, following the issuance of AD 2007-0034 by the European Aviation Safety Authority (EASA) for Socata TB 200 model aircraft, CASA issued Australian AD/TB 200/10. These directives are issued without public consultation and do not require a Regulatory Impact Statement, reflecting their technical nature and the imperative for swift regulatory action to maintain safety.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, lays out provisions for the issuance of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs for specific types of aircraft or aeronautical products. This regulation ensures that the ADs serve as a legislative instrument, which can be disallowed under section 46A of the Acts Interpretation Act 1901, as per subregulation 39.001(5). These ADs are instrumental in maintaining the continuing airworthiness of aircraft, as stipulated under Annex 8 to the Convention on International Civil Aviation.
The responsibilities outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are significant. The State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry to ensure compliance with safety standards. The State of Registry is tasked with developing or adopting requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. In the case of Australia, CASA, as the national airworthiness authority, must assess ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs to enforce the required safety measures.
Breaching the requirements set forth by ADs can have serious legal consequences. Under the Civil Aviation Act 1988, failure to comply with an AD can result in both civil and criminal penalties. For instance, operating an aircraft in a manner that contravenes an AD can lead to fines or imprisonment, depending on the severity of the violation. The specific penalties are not detailed in the provided text, but they can be significant, reflecting the importance of adhering to airworthiness directives to maintain safety in aviation.
The process for issuing ADs, as described in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, is designed to ensure that safety measures are implemented efficiently and effectively. When a State of Design issues an AD, CASA must assess the information and issue a corresponding Australian AD if necessary. This was the case with the European Aviation Safety Authority's AD 2007-0034 affecting Socata TB 200 model aircraft, which CASA assessed and issued as Australian AD/TB 200/10. Given that this AD was issued due to Australia’s obligations under the Convention on International Civil Aviation and in response to an AD from the relevant State of Design, no public consultation was required. The AD was 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.
