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.
CASA issued AD/BEECH 18/16, affecting Beech 18 model aircraft in 1971. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 20 December 2007. No replacement AD is required, as the original unsafe condition is now covered by AD/GENERAL/74.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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 ensure the safety of air navigation, providing the legal framework for regulating aviation activities within Australia. The Act empowers the Governor-General to make regulations in the interests of safety, with specific provisions for issuing airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs serve as legislative instruments to mandate airworthiness requirements for aircraft and aeronautical products. The Civil Aviation (Safety Authority) Act 1990 establishes the Civil Aviation Safety Authority (CASA) as the national airworthiness authority, responsible for implementing and enforcing ADs. The objective of these regulations is to ensure the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). This legislative framework addresses the need for consistent and stringent safety measures in the aviation sector to protect public safety and maintain international compliance.
Scope and Application
The Civil Aviation Act 1988 provides a legislative framework for the regulation of civil aviation in Australia, and under this Act, the Civil Aviation Safety Regulations 1998 have been made to specify the requirements for air navigation safety. Regulation 39.001 of these Regulations empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, which are legislative instruments that mandate specific actions to ensure the continuing airworthiness of the aircraft. The ADs issued by CASA, including AD/BEECH 18/16 which was subsequently cancelled, apply to the relevant aircraft and their operators within Australia. These ADs are issued in accordance with international standards, specifically Annex 8 to the Convention on International Civil Aviation, which assigns responsibility for the continuing airworthiness of aircraft to the State of Design and the State of Registry. CASA, as Australia’s national airworthiness authority, ensures that Australian aircraft meet these continuing airworthiness standards by issuing ADs as necessary. The cancellation of AD/BEECH 18/16, effective from 20 December 2007, was made without public consultation because it resulted in a reduction of regulatory burden, and no Regulatory Impact Statement was required as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, and specifically section 98, empowers the Governor-General to enact regulations that serve the interests of air navigation safety. This legislative framework is further elaborated upon in the Civil Aviation Safety Regulations 1998, where regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. Subregulation 39.001(5) clarifies that these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, thus classifying them as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions require CASA to act as Australia’s national airworthiness authority, ensuring the safety and airworthiness of aircraft registered in Australia. When the State of Design issues an AD against a type of aircraft on the Australian Register, CASA must assess this information and, if necessary, issue a corresponding Australian AD to enforce the requirements stipulated by the State of Design. This process underscores the importance of international collaboration in maintaining aircraft safety standards, as stipulated under Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the overarching responsibility for the continuing airworthiness of an aircraft type.
In terms of consequences for non-compliance, the Civil Aviation Act 1988 does not explicitly detail specific offences or penalties for breaching airworthiness directives. However, the overarching regulatory framework implies that failure to comply with CASA's ADs could potentially lead to severe civil or criminal penalties, as non-compliance with safety regulations can result in significant safety risks. The seriousness of these potential consequences highlights the importance of adhering to ADs issued by CASA.
The cancellation of AD/BEECH 18/16, which affects Beech 18 model aircraft from 1971, serves as an example of CASA's regulatory actions. The decision to cancel this AD was made by the Manager, Airframes, in the Airworthiness Engineering Branch, on behalf of CASA, under subsection 84A(2) of the Act. The cancellation of this AD will take effect on 20 December 2007, and no replacement AD is required as the original safety concern is now addressed by AD/GENERAL/74. Notably, no consultation with the Australian public was conducted for this cancellation, as it results in a reduction of the regulatory burden. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement.
