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 NZ CAA has issued AD DCA/750XL/7A affecting PAC Model 750XL aircraft. New Zealand is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/750XL/7, Amendment 1, which will become effective on 6 January 2006. This AD cancels and replaces the previous issue.
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, was established to provide a framework for the regulation of civil aviation within Australia, with a primary focus on ensuring the safety of air navigation. As a key instrument within this legislative framework, the Civil Aviation Safety Regulations 1998 further operationalise the Act’s provisions by enabling the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are designed to ensure the continuing airworthiness of aircraft and aeronautical products, aligning with international standards and obligations under the Convention on International Civil Aviation. The Act and its associated regulations empower CASA to mandate safety requirements for aircraft registered in Australia, particularly when corresponding directives are issued by the State of Design, thus facilitating a coordinated international approach to aviation safety.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance of airworthiness directives (ADs) in Australia, ensuring compliance with international standards for the safety of air navigation. Under this Act, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products to maintain or ensure airworthiness. These ADs are issued pursuant to the authority granted by the Governor-General under section 98 of the Act, and they constitute legislative instruments as per the Legislative Instruments Act 2003. In this context, CASA acts as Australia's national airworthiness authority, assessing and implementing ADs issued by the State of Design or other relevant authorities, such as the New Zealand Civil Aviation Authority (NZ CAA). This process ensures that Australian aircraft meet international safety standards as outlined in Annex 8 to the Convention on International Civil Aviation. The issuance of ADs does not require public consultation or a Regulatory Impact Statement, reflecting their technical nature and the necessity for swift regulatory action in aviation safety matters.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are central to the regulation of airworthiness directives (ADs) in Australia. Section 98 of the Act empowers the Governor-General to create regulations that serve the interests of safety in air navigation. Regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are legislative instruments as per subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are multifaceted. The State of Design, which in this case is New Zealand for the PAC Model 750XL aircraft, holds the primary responsibility for the continuing airworthiness of the aircraft type, as stipulated by Annex 8 to the Convention on International Civil Aviation. This includes providing necessary information to ensure the airworthiness of the aircraft type to the States of Registry. For Australia, the State of Registry, CASA must assess the AD issued by the State of Design and, if deemed appropriate, issue an Australian AD that mandates the requirements set forth by the State of Design. In this instance, CASA has issued Australian AD/750XL/7, Amendment 1, which cancels and replaces the previous AD and will take effect on 6 January 2006.
Failure to comply with ADs can lead to severe consequences. The regulations do not explicitly detail the offences, penalties, or civil/criminal consequences for non-compliance in this particular legislation excerpt. However, generally, non-compliance with ADs can result in the grounding of the aircraft, fines, and other enforcement actions taken by CASA. The specific penalties would depend on the nature and severity of the non-compliance, as outlined in other sections of the Civil Aviation Act 1988 and related regulations. CASA is authorised to take necessary actions to ensure that the ADs are adhered to, thereby maintaining the high safety standards required in civil aviation.
