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 issued AD 2005-26-03, affecting Boeing B737 aircraft, in 2005. The USA is the State of Design for this type. As a result of a request from industry, CASA has amended the equivalent Australian AD to allow the use of an updated Boeing Service Bulletin. The amended AD, AD/B737/278 Amendment 1, will become effective on 7 August 2009. 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager Initial Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, with a strong emphasis on safety. The Act empowers the Governor-General to create regulations for the safety of air navigation, with the Civil Aviation Safety Regulations 1998 further detailing the implementation of these regulations. One significant aspect of these regulations is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft. These ADs serve as a legislative instrument under the Acts Interpretation Act 1901, reflecting Australia's commitment to international standards as outlined in the Convention on International Civil Aviation. CASA is responsible for assessing and issuing ADs based on information provided by the aircraft's State of Design, ensuring that Australian-registered aircraft meet necessary safety standards. This approach maintains alignment with global aviation safety practices and ensures the safety and reliability of aircraft operating within Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, as amended, apply to all aircraft registered in Australia and to aeronautical products used in Australian aviation. These regulations are designed to ensure the safety of air navigation and the continuing airworthiness of aircraft. Under the Act, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments that are subject to disallowance under the Acts Interpretation Act 1901 and must comply with the Legislative Instruments Act 2003. The ADs are issued in accordance with international obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry. The State of Registry, in turn, must ensure the aircraft's continuing airworthiness by adopting or developing appropriate requirements. In the case of ADs issued by the State of Design, CASA must assess the information and, if necessary, issue corresponding Australian ADs to enforce the requirements. For instance, following a U.S. Federal Aviation Administration (FAA) AD for Boeing B737 aircraft, CASA has amended the corresponding Australian AD to incorporate an updated Boeing Service Bulletin. This AD, effective from 7 August 2009, cancels and replaces the previous issue. The AD was made under the authority of the Act, without public consultation, as it is aligned with international obligations and follows an AD from the relevant State of Design.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (39.001). These directives are instrumental in ensuring the continuing airworthiness of aircraft and are considered legislative instruments under the Legislative Instruments Act 2003 (6). Subregulation 39.001(5) specifies that ADs are disallowable instruments as per the Acts Interpretation Act 1901 (46A). Consequently, any AD issued by CASA must align with the requirements of the Civil Aviation Act 1988 and the overarching goal of enhancing aviation safety.
The obligations imposed by these regulations require CASA, as Australia's national airworthiness authority, to meticulously assess any AD issued by the State of Design concerning a type of aircraft registered in Australia. If deemed appropriate, CASA must issue a corresponding Australian AD to enforce the State of Design’s requirements. This ensures that all aircraft registered in Australia meet international safety standards and comply with relevant regulatory mandates. The State of Registry must implement these requirements to maintain the airworthiness of individual aircraft, thereby upholding both national and international safety standards.
Breaching the obligations set forth by the Civil Aviation Safety Regulations 1998 can lead to significant consequences. For instance, failure to comply with an AD may result in the grounding of affected aircraft, which can incur substantial financial losses for operators and potentially endanger public safety. Additionally, CASA may impose penalties on non-compliant entities, which can include fines or other sanctions as stipulated under the Civil Aviation Act 1988. In severe cases, regulatory action may be taken against operators who fail to adhere to the mandated airworthiness directives, further underscoring the importance of compliance with these regulations.
In summary, the ADs issued under the Civil Aviation Safety Regulations 1998 are critical for ensuring the safety and airworthiness of aircraft registered in Australia. CASA’s role in issuing and enforcing these directives is paramount, and compliance is mandatory for all relevant parties. Non-compliance not only risks significant penalties but also compromises the safety of air travel, making adherence to these regulations essential for all stakeholders within the aviation industry.
