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 2007-05-10 affecting Cessna 180 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/CESSNA 180/89, which will become effective on 11 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, enacted by the Australian Parliament, addresses the need for stringent safety regulations in air navigation, with a particular focus on ensuring the airworthiness of aircraft and aeronautical products. This Act empowers the Governor-General to make regulations that serve the interests of aviation safety, including the issuance of airworthiness directives (ADs) to mandate necessary safety measures. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further stipulates that the Civil Aviation Safety Authority (CASA) can issue ADs for specific kinds of aircraft or aeronautical products. These directives, which are legislative instruments, are critical in ensuring that aircraft continue to meet safety standards throughout their operational life. The Civil Aviation Act 1988 and its associated regulations align with international obligations under the Convention on International Civil Aviation, particularly Annex 8, which places the responsibility of ensuring continuing airworthiness on the State of Design and the State of Registry. CASA, acting as Australia’s national airworthiness authority, assesses and, where necessary, issues Australian ADs to enforce the requirements set by the relevant State of Design, ensuring compliance with both national and international safety standards.
Scope and Application
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 provide the legal framework for ensuring the safety of air navigation in Australia. Specifically, regulation 39.001 of these Regulations empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. This authority is exercised in accordance with Annex 8 to the Convention on International Civil Aviation, which delineates the responsibilities of the State of Design and State of Registry concerning the continuing airworthiness of aircraft. The ADs, serving as critical tools for maintaining airworthiness, are issued by CASA in response to directives from the relevant State of Design, ensuring compliance with international obligations and safety standards. An example of this is CASA's issuance of AD/CESSNA 180/89 in response to an AD by the US Federal Aviation Administration concerning Cessna 180 model aircraft. This AD was made without public consultation as it arises from Australia's commitments under international aviation conventions and has been assessed as not requiring a Regulatory Impact Statement. The issuance of such directives is a legislative instrument under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, reflecting their statutory significance in maintaining aviation safety.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to create regulations that ensure the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is granted the authority to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby classifying them as legislative instruments as per section 6 of the Legislative Instruments Act 2003.
In line with Annex 8 of the Convention on International Civil Aviation, the State of Design, which is the country where the aircraft was designed, bears the overarching responsibility for the continuing airworthiness of the aircraft type. This includes providing all necessary information to ensure the aircraft's ongoing airworthiness to the States of Registry. The State of Registry, which is the country where the aircraft is registered, must then develop or adopt requirements to maintain the airworthiness of the aircraft. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA, as the national airworthiness authority, must assess the information and, if deemed necessary, issue an Australian AD to enforce the requirements of the State of Design.
The US Federal Aviation Administration (FAA) has issued AD 2007-05-10, which affects Cessna 180 model aircraft. Since the USA is the State of Design for this aircraft type, CASA has evaluated the AD and subsequently issued Australian AD/CESSNA 180/89, which will take effect on 11 April 2007. Given that this AD is issued due to Australia's obligations under the Convention on International Civil Aviation and in response to an AD issued by the relevant State of Design, no public consultation has been required. Moreover, the Office of Regulatory Review has determined that ADs do not necessitate a Regulatory Impact Statement. This AD was created by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office on behalf of CASA, in compliance with subsection 84A(2) of the Act.
CASA, as the national airworthiness authority, has specific obligations under the Civil Aviation Safety Regulations 1998. These include assessing ADs issued by the State of Design and, if necessary, issuing corresponding Australian ADs to ensure the continuing airworthiness of aircraft registered in Australia. The State of Registry is also responsible for developing or adopting requirements to maintain the airworthiness of aircraft registered within its jurisdiction. Failure to comply with these obligations can result in significant safety risks, potentially leading to aircraft being deemed unairworthy and thus grounded.
Breach of the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to both civil and criminal consequences. The specific penalties vary depending on the nature and severity of the breach. Civil penalties can include fines, while criminal penalties may include imprisonment. The exact penalties are not detailed within the provided text but typically involve substantial fines and potential imprisonment for serious breaches that endanger safety. The enforcement of these penalties is intended to ensure compliance with airworthiness standards and maintain the highest levels of safety in civil aviation.
