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 DGAC has issued AD 2001-368-045(A) affecting EUROCOPTER SA 315 helicopters. France is the State of Design for this helicopter. CASA has assessed this AD and has issued Australian AD/SA 315/14, which will become effective on 12 April 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, New Technologies and Systems, 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 legislative framework for the regulation of civil aviation in Australia, addressing the need for a unified and safe approach to air navigation and aviation safety. This Act empowers the Governor-General to make regulations necessary for the safety of air navigation, ensuring that the aviation industry adheres to stringent safety standards. Complementing the Civil Aviation Act is the Civil Aviation Safety Regulations 1998, which include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs, which are legislative instruments under the Acts Interpretation Act 1901, mandate the continuing airworthiness of aircraft in alignment with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Act and its associated regulations reflect Australia's commitment to international aviation safety protocols, particularly in relation to the responsibilities of the State of Design and the State of Registry in maintaining aircraft airworthiness.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) within Australia. Pursuant to section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations for the safety of air navigation, with regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowering the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. The ADs are considered legislative instruments under the Legislative Instruments Act 2003. These directives are integral to ensuring the continuing airworthiness of aircraft types, aligning with Annex 8 of the Convention on International Civil Aviation, which assigns responsibility to the State of Design and State of Registry for aircraft airworthiness. CASA, as Australia's national airworthiness authority, is obligated to issue Australian ADs in response to directives from the State of Design, such as the recent Australian AD/SA 315/14 issued in response to AD 2001-368-045(A) by France for EUROCOPTER SA 315 helicopters. The process does not require public consultation or a Regulatory Impact Statement as it stems from international obligations and directly responds to State of Design directives. The ADs are formulated by CASA officials under the authority granted by the Act, ensuring compliance with international standards and safeguarding air navigation safety.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides a framework through which airworthiness directives (ADs) are issued to ensure the safety of aircraft. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the purposes of the Act, with a focus on safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are legal instruments, as they are considered disallowable under section 46A of the Acts Interpretation Act 1901 and therefore are legislative instruments under section 6 of the Legislative Instruments Act 2003.
These ADs are integral to maintaining the continuing airworthiness of aircraft, a responsibility that falls on the State of Design and the State of Registry as per Annex 8 to the Convention on International Civil Aviation. The State of Design, such as France for the EUROCOPTER SA 315 helicopter, must provide necessary information to ensure that the aircraft type remains airworthy. The State of Registry, in this case Australia, must then implement these requirements domestically through CASA, which is Australia’s national airworthiness authority. CASA assesses ADs issued by States of Design and, if deemed necessary, issues Australian ADs to mandate these requirements, as seen in the case of AD/SA 315/14 for the EUROCOPTER SA 315 helicopters, which became effective on 12 April 2007.
Entities governed by these provisions, such as CASA, have the obligation to assess foreign ADs and issue corresponding Australian ADs when necessary. This ensures that Australian-registered aircraft meet international safety standards. Additionally, manufacturers, operators, and owners of affected aircraft must comply with the ADs, which may include conducting maintenance, repairs, or modifications to ensure airworthiness. Failure to comply with these ADs can result in significant civil and criminal consequences, including fines and imprisonment. The severity of these penalties underscores the importance of adhering to airworthiness directives to maintain safety standards in civil aviation.
