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 2008-10-03 affecting Bell 212 model helicopters. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 212/69, which will become effective on 21 May 2008.
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 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 regulate civil aviation in Australia and to ensure the safety of air navigation. Under this Act, the Governor-General has the authority to make regulations necessary for the purposes of the Act and for the safety of air navigation, as exemplified in the issuing of airworthiness directives by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998 further empower CASA to issue airworthiness directives for specific types of aircraft or aeronautical products, which are integral to maintaining the continuing airworthiness of aircraft as mandated by international agreements such as the Convention on International Civil Aviation. These directives are legislative instruments subject to disallowance and are issued in compliance with Australia's obligations under international conventions, ensuring that Australian aircraft meet global safety standards.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, applies to the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Specifically, regulation 39.001 allows CASA to issue ADs for types of aircraft or aeronautical products to ensure the safety of air navigation. These ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003 and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The application of these regulations is driven by international obligations under Annex 8 to the Convention on International Civil Aviation, which places the responsibility for the continuing airworthiness of aircraft types on the State of Design, and on the State of Registry for individual aircraft. When an AD is issued by the State of Design, CASA must assess and, if necessary, issue a corresponding Australian AD to enforce the requirements on aircraft registered in Australia. This process is exemplified by the issuance of Australian AD/BELL 212/69 in response to the US FAA's AD 2008-10-03 for Bell 212 model helicopters. The ADs are issued without public consultation as they are mandated by international agreements and do not require a Regulatory Impact Statement, in line with the determination of the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the legislative framework under which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Specifically, section 98 of the Act allows the Governor-General to make regulations for air safety, and regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Under subregulation 39.001(5), ADs are considered disallowable instruments, and hence legislative instruments under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are centred on the continuing airworthiness of aircraft. The State of Design, which is responsible for the type design of an aircraft, must provide necessary information to ensure that the aircraft type remains airworthy. This is in accordance with Annex 8 to the Convention on International Civil Aviation. Correspondingly, the State of Registry, which in Australia is CASA, must adopt or develop requirements to ensure that individual aircraft remain airworthy. When a State of Design issues an AD, CASA must assess the information and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. This ensures that Australian aircraft conform to international safety standards.
Failure to comply with the requirements set out in an AD can result in serious consequences. Under section 84A(2) of the Act, CASA is empowered to issue these directives, and non-compliance with an AD can lead to significant penalties. While the specifics of these penalties are not detailed in the provided text, the Act and Regulations likely provide for both civil and criminal penalties for breaches. These could include fines, imprisonment, or other enforcement actions deemed necessary by CASA to ensure compliance with airworthiness standards. The serious nature of these potential consequences underscores the importance of adhering to ADs to maintain the high safety standards expected in civil aviation.
The legislative process for issuing an AD, such as AD/BELL 212/69 for the Bell 212 model helicopters, is stringent and follows international protocols. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, streamlining the process while maintaining rigorous oversight. CASA, as Australia’s national airworthiness authority, ensures that Australian ADs are issued in response to international directives and in line with Australia’s obligations under the Convention on International Civil Aviation. This coordinated approach ensures that all stakeholders are informed and that safety remains the paramount concern.
