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 Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 337/12 affecting Cessna 337 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 337/12. The cancellation will become effective on 5 June 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Systems and New Technologies 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 regulate civil aviation in Australia, focusing primarily on the safety of air navigation. Under this Act, the Governor-General has the authority to create regulations for the safety of air navigation, as exemplified by the Civil Aviation Safety Regulations 1998. These regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. ADs are critical tools for maintaining the continuing airworthiness of aircraft, in line with Australia’s obligations under the Convention on International Civil Aviation. The Civil Aviation Safety Authority, acting as Australia’s national airworthiness authority, is responsible for assessing information from the State of Design and issuing Australian ADs where necessary. Recently, CASA assessed and subsequently cancelled AD/CESSNA 337/12 affecting Cessna 337 aircraft, effective from 5 June 2008, as the unsafe condition it addressed no longer exists. This action was taken in accordance with Australia’s international obligations and did not require public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) pertaining to specific types of aircraft or aeronautical products. These ADs, which are legislative instruments, serve as crucial tools for maintaining the continuing airworthiness of aircraft, aligning with the obligations set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design, responsible for the overall airworthiness of an aircraft type, must provide necessary information to States of Registry to ensure the safe operation of aircraft. CASA, acting as Australia's national airworthiness authority, is obligated to assess this information and, if necessary, issue corresponding Australian ADs. An example of this regulatory process is the issuance and subsequent cancellation of Australian AD/CESSNA 337/12 for Cessna 337 aircraft, which was cancelled on 5 June 2008 as the identified unsafe condition no longer existed. This cancellation was made in accordance with the Civil Aviation Act 1988, without the need for public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, sets out the framework for ensuring the safety and airworthiness of aircraft. Under section 98 of the Act, the Governor-General can make regulations for air navigation safety, and regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This regulatory power is integral to maintaining safety standards in the aviation industry. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, which underscores their legal standing and enforceability.
The obligations imposed by the Act and the Regulations are significant. The State of Design, which is the country where the aircraft type is designed, has the primary responsibility for ensuring the continuing airworthiness of the aircraft type. This responsibility includes providing necessary information to the States of Registry, which are the countries where individual aircraft are registered. CASA, as Australia's national airworthiness authority, must assess the information from the State of Design and, if necessary, issue an Australian AD to enforce the required safety measures. This process ensures that the safety standards are consistently applied across all aircraft operating within Australia.
Breaching the requirements set out in these ADs can have serious consequences. The Civil Aviation Act 1988 provides for both civil and criminal penalties for non-compliance. Civil penalties can include fines, while criminal penalties may include imprisonment, reflecting the seriousness of ensuring aviation safety. For instance, operating an aircraft that does not comply with an AD could result in penalties under the Act. The maximum penalties for offences under the Act can vary, but they are designed to enforce compliance and maintain high safety standards in the aviation sector.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for ensuring the safety and airworthiness of aircraft. The issuing and enforcement of ADs by CASA are critical to this framework, ensuring that all aircraft meet the necessary safety standards. The obligations on the States of Design and Registry, as well as the potential penalties for non-compliance, underscore the importance of adhering to these regulations to protect public safety in aviation.
