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 EASA has issued AD 2006-0345 affecting MT Propellers. The EASA is the State of Design for these propellers. CASA has assessed this AD and has issued Australian AD/PMTV/2, 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, New Technologies and Systems, 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, enacted by the Australian Parliament, is a foundational piece of legislation governing civil aviation in Australia. The Act was introduced to establish a comprehensive framework for ensuring the safety and efficiency of civil aviation within Australia and its territories. In line with the objectives of the Act, the Civil Aviation Safety Regulations 1998 were introduced to provide detailed regulatory provisions to uphold air safety standards. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations that serve the interests of air navigation safety. The Civil Aviation Safety Regulations 1998 further delegate authority to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as outlined in regulation 39.001. The process of issuing ADs is crucial for maintaining the continuing airworthiness of aircraft, which is a shared responsibility between the State of Design and the State of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation. CASA, as the national airworthiness authority, is mandated to assess and, if necessary, issue Australian ADs in response to directives from the State of Design to ensure compliance with international aviation safety standards.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legal framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). These ADs apply to aircraft and aeronautical products within Australia and are mandated under section 39.001 of the Regulations, which empowers CASA to issue such directives for specific types of aircraft or aeronautical products. As per the legislative framework, ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments under section 6 of the Legislative Instruments Act 2003. The application of these directives is aligned with the international obligations under Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of an aircraft type. Consequently, when the European Aviation Safety Agency (EASA), as the State of Design, issues an AD affecting aircraft registered in Australia, CASA is obligated to assess and, if necessary, issue a corresponding Australian AD. The issuance of such directives is intended to ensure the safety and airworthiness of aircraft operating within Australian jurisdiction, without requiring public consultation or a Regulatory Impact Statement as per the Office of Regulatory Review’s determination.
Key Provisions
The Civil Aviation Act 1988, and specifically section 98, empowers the Governor-General to create regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 extends this authority to the Civil Aviation Safety Authority (CASA), allowing them to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs serve as legal instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments under section 6 of the Legislative Instruments Act 2003.
Under these provisions, CASA is obligated to assess any ADs issued by the State of Design, particularly when they pertain to aircraft types registered in Australia. The State of Design, which in this case is the European Aviation Safety Agency (EASA) for MT Propellers, has issued AD 2006-0345. CASA, upon evaluating this directive, has issued Australian AD/PMTV/2, effective from 12 April 2007. This demonstrates CASA’s role in ensuring that Australian aircraft comply with international airworthiness standards.
The obligations imposed on entities such as CASA and the State of Registry include the assessment and enforcement of ADs to maintain the continuing airworthiness of aircraft. The State of Design, by issuing ADs, also shares the responsibility of ensuring safety standards are met. The State of Registry must develop or adopt measures that align with international standards to ensure the safety of aircraft registered within their jurisdiction.
Failure to comply with ADs can result in serious consequences. While specific penalties are not detailed in the provided text, breaches of airworthiness regulations can lead to significant civil or criminal liabilities. These may include fines, imprisonment, or other penalties as prescribed by relevant aviation laws. The seriousness of non-compliance underscores the importance of adhering to ADs to maintain safety standards in air navigation.
