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 French DGAC has issued AD F-2000-520-159(B) affecting Airbus A319, A320 and A321 model aircraft. France is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/A320/215, which will become effective on 5 June 2008.
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, 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 to provide a comprehensive legal framework for civil aviation in Australia, with a strong emphasis on safety and efficiency. One of its primary functions is to empower the Governor-General to make regulations under section 98 of the Act, ensuring these regulations align with the safety of air navigation. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, specifically enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft or aeronautical products. The ADs, as outlined in regulation 39.001(5) of the Civil Aviation Safety Regulations, are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and thus qualify as legislative instruments under section 6 of the Legislative Instruments Act 2003. These directives play a crucial role in maintaining the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO) under Annex 8 of the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 applies to the regulation of air navigation safety in Australia and empowers the Governor-General to make regulations for this purpose. Under the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are legislative instruments subject to disallowance and the Legislative Instruments Act 2003. These ADs are integral to ensuring the continuing airworthiness of aircraft and are issued in accordance with Annex 8 of the Convention on International Civil Aviation. The State of Design, such as France for Airbus A319, A320 and A321 models, has the primary responsibility for issuing ADs for aircraft types, while the State of Registry, in this case CASA for Australia, is tasked with ensuring the continuing airworthiness of individual aircraft on its register by adopting or developing appropriate requirements. Consequently, CASA assesses foreign ADs and issues corresponding Australian ADs, such as AD/A320/215 in response to the French AD F-2000-520-159(B), without the need for public consultation or a Regulatory Impact Statement due to their international obligations and specific regulatory nature.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure air navigation safety. These ADs, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, serve as crucial tools for maintaining the continuing airworthiness of aircraft types. This responsibility is underscored by Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the duty to provide necessary information to ensure the airworthiness of aircraft types, with the State of Registry obligated to implement these requirements for individual aircraft. For instance, following the issuance of AD F-2000-520-159(B) by the French DGAC for Airbus A319, A320, and A321 models, CASA issued Australian AD/A320/215 in alignment with its regulatory obligations.
Under this framework, CASA, acting as Australia's national airworthiness authority, assumes a pivotal role in ensuring the safety and compliance of aircraft registered in Australia. When a State of Design issues an AD, CASA evaluates the provided information and, if necessary, issues a corresponding Australian AD to enforce the design state's requirements. This process is exemplified by CASA's issuance of AD/A320/215 in response to the French AD F-2000-520-159(B), which became effective on 5 June 2008. Given that ADs are issued due to international obligations and in response to directives from the relevant State of Design, they do not necessitate public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
The obligations imposed on parties governed by these regulations are significant. CASA, as the issuing authority, must ensure that ADs are consistent with international safety standards and are effectively communicated to relevant stakeholders, including aircraft operators and maintenance providers. Aircraft operators and owners must comply with the requirements stipulated in ADs, which may include specific maintenance actions, inspections, and operational limitations. Failure to adhere to these directives can result in serious safety risks and potential legal consequences. CASA's authority to issue ADs is exercised through the Manager, Airframes in the Airworthiness Engineering Branch, in accordance with section 84A(2) of the Act.
In terms of consequences for non-compliance, the Civil Aviation Safety Regulations 1998 impose strict penalties and legal actions for breaches of ADs. Non-compliance with an AD can lead to civil penalties, including fines and potential criminal charges, depending on the severity of the breach and its impact on safety. The specific penalties are outlined in the regulations and can vary, but they underscore the critical importance of adhering to airworthiness directives. Ensuring compliance with ADs is fundamental to maintaining the safety and integrity of the aviation industry, both domestically and internationally.
