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 Dutch CAA has issued AD NL-2005-0013 affecting Fokker F28 Mark 0100 and 0070 model aircraft. The Netherlands is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/F100/73, which will become effective on 22 December 2005.
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 introduced to regulate civil aviation safety and ensure the safety of air navigation. In line with this objective, the Civil Aviation Safety Regulations 1998 were formulated to provide the legal framework for ensuring the continuing airworthiness of aircraft and aeronautical products. The issuance of airworthiness directives (ADs) under this legislation plays a crucial role in maintaining the safety standards required by international conventions, such as Annex 8 to the Convention on International Civil Aviation. ADs serve as a means for the State of Design to communicate necessary information to the State of Registry, ensuring that all aircraft meet specific safety requirements. CASA, as Australia's national airworthiness authority, is responsible for issuing Australian ADs based on assessments of directives from the State of Design, thereby fulfilling Australia’s obligations under international aviation agreements. This process ensures that safety directives from other countries are appropriately implemented within Australia, without the need for public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework under which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are considered legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The ADs must align with Annex 8 to the Convention on International Civil Aviation, which places the responsibility of continuing airworthiness on the State of Design, requiring it to provide necessary information to the States of Registry. In Australia, CASA acts as the national airworthiness authority, tasked with assessing ADs issued by the State of Design and, if appropriate, issuing corresponding Australian ADs. The issuance of these directives does not require public consultation and does not necessitate a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The ADs are prepared by CASA officials, such as the Manager, Airframes, in accordance with the relevant provisions of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the associated Civil Aviation Safety Regulations 1998 outline a comprehensive framework for ensuring the safety of air navigation in Australia. Section 98 of the Act allows the Governor-General to make regulations for air navigation safety, while regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. Section 39.001(5) of the Regulations further clarifies that ADs are legislative instruments subject to disallowance under section 46A of the Acts Interpretation Act 1901, and are regulated as such under the Legislative Instruments Act 2003. These ADs are a critical mechanism for ensuring the continuing airworthiness of aircraft, in line with international standards as set out in Annex 8 to the Convention on International Civil Aviation.
Under the Civil Aviation Act 1988, CASA, as Australia’s national airworthiness authority, has several key responsibilities. It must ensure that any airworthiness directives issued by the State of Design, the country where the aircraft was designed, are assessed for their applicability to aircraft registered in Australia. If deemed necessary, CASA issues its own ADs to mandate the requirements of the State of Design. This process is exemplified by the Dutch Civil Aviation Authority's AD NL-2005-0013, which affects Fokker F28 Mark 0100 and 0070 models. CASA has issued Australian AD/F100/73 in response, which will take effect on 22 December 2005. These actions underscore CASA’s role in maintaining airworthiness standards in accordance with international obligations and national safety requirements.
The obligations imposed by the Act and Regulations on parties governed by them are significant. CASA must rigorously assess foreign ADs and, where necessary, issue corresponding Australian ADs. This ensures that all aircraft registered in Australia meet the continuing airworthiness standards set forth by the relevant State of Design. Additionally, the State of Registry for each aircraft must develop or adopt requirements to ensure ongoing airworthiness, as mandated by Annex 8 of the Convention on International Civil Aviation. This dual responsibility ensures that both design and registry states contribute to maintaining the safety and airworthiness of aircraft.
The legislation also outlines the consequences for non-compliance with the Act and its associated regulations. While the specific provisions of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 do not detail the exact penalties for breach, the issuance of ADs and the failure to comply with them can have serious ramifications. Non-compliance could lead to enforcement actions by CASA, which may include fines, suspension or revocation of airworthiness certificates, or other regulatory penalties. These measures are intended to ensure that all stakeholders adhere to the highest safety standards, thereby protecting the public and maintaining the integrity of the aviation system.
