CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 DGAC has issued AD F-2005-052 R1 affecting Airbus Model A320 aircraft. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A320/175, which will become effective on 9 June 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 Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, was introduced to provide a comprehensive framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of the aviation industry. The Act addresses the need for a unified legislative approach to the management of air navigation safety and the oversight of aircraft airworthiness. In line with its policy objective of maintaining high safety standards, the Act grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) through regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are considered legislative instruments under the Legislative Instruments Act 2003 and are essential for ensuring the continuing airworthiness of aircraft types registered in Australia. CASA, as the national airworthiness authority, must issue Australian ADs in response to ADs from the State of Design when necessary to comply with international civil aviation conventions. This legislative mechanism underscores Australia's commitment to international safety standards while maintaining domestic air navigation safety.
Scope and Application
The Civil Aviation Act 1988, through regulation 39.001 of the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This legislation applies to all aircraft registered in Australia and those operating within Australian airspace, ensuring adherence to airworthiness standards that are in line with international obligations under the Convention on International Civil Aviation. Airworthiness directives are legislative instruments that CASA issues to maintain or improve the safety of air navigation, and they are mandated by Australia's role as a State of Registry. The authority to issue ADs is exercised in response to directives from the State of Design, such as the French Directorate General for Civil Aviation (DGAC) issuing AD F-2005-052 R1 for Airbus A320 aircraft. CASA's assessment of such international directives results in the issuance of corresponding Australian ADs, such as AD/A320/175, which becomes effective on a specified date. This process does not involve public consultation or require a Regulatory Impact Statement, reflecting the necessity for prompt action in matters of aviation safety.
Key Provisions
The key sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) that are critical for ensuring the continuing airworthiness of aircraft. Section 98 of the Act empowers the Governor-General to make regulations in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Subregulation 39.001(5) clarifies that ADs are legislative instruments that are subject to disallowance under section 46A of the Acts Interpretation Act 1901.
Under these provisions, CASA has the responsibility to issue ADs when necessary, particularly in response to directives issued by the State of Design, such as the recent AD/A320/175 issued for Airbus A320 aircraft. This directive was issued following the French Civil Aviation Authority's AD F-2005-052 R1. The State of Design, France, has a primary obligation to provide information to ensure the continuing airworthiness of aircraft types. Meanwhile, the State of Registry, Australia, must develop or adopt requirements to ensure the same. In this case, CASA has assessed the French AD and issued the Australian equivalent, ensuring compliance with international obligations under the Convention on International Civil Aviation.
Entities governed by the Act, including CASA and the aircraft operators, must adhere to the ADs issued by CASA. CASA is responsible for assessing foreign ADs and issuing corresponding Australian ADs, ensuring that all aircraft on the Australian Register meet the required safety standards. Aircraft operators must comply with these directives by implementing the necessary modifications, inspections, and maintenance actions specified in the ADs to maintain airworthiness. Failure to comply with ADs can result in severe consequences, including civil penalties for non-compliance with safety regulations. Under section 84A of the Civil Aviation Act 1988, CASA can impose penalties on non-compliant aircraft operators, which may include fines and potential grounding of non-compliant aircraft. This ensures that all aircraft operating in Australia meet the highest safety standards.
