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/CESSNA 337/4, affecting Cessna 337 series aircraft in 1967. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 5 June 2008. No replacement AD is required, there are no longer any affected aircraft operating in Australia, and all affected aircraft would have been modified long ago.
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, enacted by the Australian Parliament, governs the regulation of civil aviation within Australia and aims to ensure the safety of air navigation. One key component of this framework is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs, which are legislative instruments under the Legislative Instruments Act 2003, mandate requirements for the continuing airworthiness of aircraft types and aeronautical products. The Civil Aviation Safety Regulations 1998 provide the regulatory basis for CASA to issue these directives, ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO). Recently, CASA decided to cancel AD/CESSNA 337/4, which affected Cessna 337 series aircraft manufactured in 1967, as no affected aircraft remain in operation in Australia and all necessary modifications have been completed. This decision, made under the authority of the Act, was executed without public consultation and deemed not to require a Regulatory Impact Statement, reflecting a reduction in regulatory burden.
Scope and Application
The Civil Aviation Act 1988, as augmented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance and management of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). This Act applies to aircraft operators, manufacturers, and other entities involved in the aviation industry, ensuring compliance with safety regulations. The Act's jurisdiction extends across Australia, reflecting the national scope of air navigation safety. An AD is a legislative instrument that can be issued under regulation 39.001 of the Civil Aviation Safety Regulations 1998, and it serves as a critical tool for maintaining the continuing airworthiness of aircraft. The ADs are issued in response to safety concerns identified by the State of Design or Registry, and CASA's role is to assess these directives and, if necessary, issue corresponding Australian ADs. In the case of AD/CESSNA 337/4, CASA has decided to cancel the directive for the Cessna 337 series aircraft, effective 5 June 2008, due to the absence of affected aircraft operating in Australia and the completion of required modifications. The cancellation of this AD is a result of regulatory simplification, and it does not require a Regulatory Impact Statement or public consultation. The AD cancellation decision was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the legislative requirements.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further authorises CASA (Civil Aviation Safety Authority) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These directives are designed to ensure that aircraft remain in a condition that is safe for operation. According to subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and consequently, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and its regulations require CASA to issue ADs when necessary to ensure the continuing airworthiness of aircraft. The State of Registry must implement or adopt measures to maintain the airworthiness of individual aircraft, while the State of Design is responsible for the overall airworthiness of the aircraft type and must provide necessary information to the States of Registry. When a State of Design issues an AD, CASA must evaluate the information and, if appropriate, issue a corresponding Australian AD to enforce the requirements of the State of Design. In the case of AD/CESSNA 337/4, which was issued by CASA for Cessna 337 series aircraft in 1967, CASA has decided to cancel the AD due to the absence of affected aircraft currently operating in Australia and the completion of necessary modifications.
Breaches of the Civil Aviation Act 1988 or the Civil Aviation Safety Regulations 1998 can result in civil and criminal penalties. The severity of the penalties varies depending on the nature and extent of the breach. For example, section 24 of the Act specifies penalties for offences related to safety and security, including fines and imprisonment. The maximum penalties can be substantial, reflecting the importance of compliance with aviation safety regulations. Additionally, individuals or entities found in breach of ADs or other regulatory requirements may face further legal consequences, including fines, suspension of operating certificates, or other enforcement actions deemed necessary by CASA to ensure compliance.
