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.
CASA issued AD/BEECH 200/23, Amendment 1, affecting Beech 200 model aircraft in 1978. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the original unsafe condition no longer exists.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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 by the Australian Parliament to establish a legislative framework that ensures the safety and efficiency of civil aviation within Australia. This Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, delegating such authority to the Civil Aviation Safety Authority (CASA). One of the critical mechanisms provided by the Act is the issuance of airworthiness directives (ADs) under the Civil Aviation Safety Regulations 1998. ADs are legislative instruments that mandate specific actions to maintain the airworthiness of aircraft and aeronautical products. They are essential for ensuring that aircraft continue to meet safety standards throughout their operational life, as required under international conventions such as Annex 8 to the Convention on International Civil Aviation. The policy objective of these regulations is to harmonise Australia's approach to aircraft airworthiness with international standards, thereby enhancing overall aviation safety.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes the framework within which the Civil Aviation Safety Authority (CASA) operates, particularly in ensuring the safety of air navigation and the continuing airworthiness of aircraft. This legislative framework allows CASA to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are formal and enforceable measures that aim to correct an unsafe condition on an aircraft, and they apply to all aircraft and aeronautical products registered in Australia. An AD is considered a legislative instrument under the Legislative Instruments Act 2003, as stipulated in section 6 and further detailed in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998. The application of these directives is in line with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design and the State of Registry have specific roles in ensuring the continuing airworthiness of aircraft. In the case of the Beech 200 model aircraft, CASA issued AD/BEECH 200/23, Amendment 1, which has since been cancelled as the unsafe condition no longer exists. This cancellation was made without public consultation as it reduces the regulatory burden and was determined not to require a Regulatory Impact Statement by the Office of Best Practice Regulation. The decision to cancel the AD was executed by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the provisions of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 (section 98) allows the Governor-General to create regulations for the safety of air navigation, and the Civil Aviation Safety Regulations 1998 (regulation 39.001) empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003 (section 6). According to Annex 8 of the Convention on International Civil Aviation, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. When a State of Design issues an AD against a type of aircraft registered in Australia, CASA must assess the information and, if necessary, issue an Australian AD to enforce the State of Design’s requirements.
The Civil Aviation Safety Regulations 1998 (subregulation 39.001(5)) establish that an AD is a disallowable instrument under the Acts Interpretation Act 1901 (section 46A), meaning it can be disallowed by Parliament. This regulation underscores the formal and legally binding nature of ADs within Australia’s aviation safety framework. For instance, CASA issued AD/BEECH 200/23, Amendment 1, which affected Beech 200 model aircraft manufactured in 1978. After review, CASA has decided to cancel this AD, effective from 10 April 2008. The cancellation is based on the fact that the original unsafe condition no longer exists, and no replacement AD is necessary. This decision reflects the continuous assessment and adaptation of safety measures to ensure the highest standards of airworthiness.
Entities and individuals governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 must comply with the ADs issued by CASA. For example, aircraft operators and owners must ensure that their aircraft meet the specified airworthiness standards outlined in the ADs. Failure to comply with an AD can result in serious safety risks and may lead to enforcement actions by CASA. Additionally, the State of Design and State of Registry have ongoing obligations to collaborate on airworthiness information, ensuring that all relevant parties are informed about the necessary maintenance and safety measures.
Failure to comply with an AD can result in severe penalties and legal consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose strict obligations on the parties involved. Violations can lead to civil penalties, such as fines, and criminal charges, particularly if the non-compliance results in an aviation accident or endangers public safety. CASA has the authority to take enforcement actions, including grounding non-compliant aircraft and prosecuting offenders. The exact penalties depend on the severity of the breach and the specific regulations violated. It is imperative for all stakeholders to adhere to the ADs to maintain the safety and integrity of the Australian aviation system.
