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 New Zealand CAA has issued AD DCA/Cresco/11 affecting Cresco 08-600 model aircraft. New Zealand is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/CRESCO/11, which will become effective on 15 February 2007.
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 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. Under this Act, the Governor-General is empowered to make regulations aimed at enhancing aviation safety, and these regulations are intended to serve the interests of both the public and the aviation industry. The Act addresses the problem of ensuring that aviation activities within Australia meet internationally recognised safety standards, while also allowing for the development of a robust domestic regulatory environment. The Civil Aviation Safety Regulations 1998, which were made under the authority of the Act, further detail the specific measures to be taken for ensuring airworthiness, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). The policy objective of these regulations is to maintain and improve the safety of civil aviation in Australia, aligning national practices with international standards as set forth by the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation in Australia. The Act empowers the Governor-General to make regulations for air safety, and regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft or aeronautical products. These directives are legislative instruments and subject to disallowance under the Acts Interpretation Act 1901. The ADs are designed to ensure that aircraft and products maintain their airworthiness standards as required by Annex 8 to the Convention on International Civil Aviation. The State of Design, which is the country where the aircraft type is designed, holds the primary responsibility for the continuing airworthiness of that type and must share necessary information with the States of Registry, which include Australia. CASA, as Australia's national airworthiness authority, is tasked with assessing foreign ADs and issuing corresponding Australian ADs when appropriate. For example, CASA issued AD/CRESCO/11 in response to a New Zealand AD concerning Cresco 08-600 model aircraft, reflecting Australia’s commitment to international civil aviation standards. These directives do not require public consultation or a Regulatory Impact Statement, as they are issued in compliance with international obligations and relevant state directives.
Key Provisions
The Civil Aviation Act 1988 (section 98) allows the Governor-General to make regulations in the interest of air navigation safety, and under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific aircraft types or aeronautical products. Section 39.001(5) of the Civil Aviation Safety Regulations 1998 further clarifies that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus are legislative instruments according to section 6 of the Legislative Instruments Act 2003. ADs are essential tools for maintaining the continuing airworthiness of aircraft as per Annex 8 to the Convention on International Civil Aviation. The State of Design, which in this context refers to the country where the aircraft type is designed, has the primary responsibility for ensuring the continuing airworthiness of the aircraft type and must provide necessary information to the States of Registry. The State of Registry, which is the country where the aircraft is registered, must then develop or adopt requirements to maintain the continuing airworthiness of the aircraft in its jurisdiction.
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 mandate that CASA, as Australia's national airworthiness authority, must assess information from the State of Design regarding ADs issued against aircraft types on the Australian Register. If necessary, CASA must issue its own ADs to enforce the requirements set by the State of Design. This process ensures that Australian aircraft meet the international standards and safety requirements set forth by ICAO Contracting States. The obligation extends to CASA ensuring that the ADs issued by other countries, such as New Zealand, are assessed and, if appropriate, adopted as Australian ADs. This was the case with AD DCA/Cresco/11 issued by New Zealand affecting Cresco 08-600 model aircraft, which CASA assessed and issued as Australian AD/CRESCO/11, effective from 15 February 2007.
Failure to comply with airworthiness directives can lead to serious legal and safety consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose strict requirements on aircraft operators, manufacturers, and maintenance providers to adhere to ADs. Breach of these requirements can result in significant penalties. Under the Act, violations may lead to civil penalties, including fines up to $216,000 for corporations and $43,200 for individuals, depending on the severity of the breach. In more serious cases, especially those involving significant safety risks, criminal penalties may apply, with maximum fines of up to $1,080,000 for corporations and $216,000 for individuals. Additionally, CASA has the authority to take enforcement actions such as grounding non-compliant aircraft, suspending or revoking airworthiness certificates, and prosecuting offenders in court. These measures underscore the importance of adhering to ADs to ensure the safety and airworthiness of aircraft operating in Australia.
