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.
Transport Canada has issued AD CD-2003-11 affecting Bell 427 helicopters. Canada is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/BELL 427/5, which will become effective on 28 September 2006.
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 framework for the regulation of civil aviation in Australia, primarily focusing on safety and efficiency. One of its key provisions allows the Governor-General to make regulations for the safety of air navigation, which includes the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are legislative instruments issued under regulation 39.001 of the Civil Aviation Safety Regulations 1998, and they are designed to address specific safety concerns with aircraft or aeronautical products. The policy objective of the ADs is to ensure the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8, which designates the State of Design with the responsibility for maintaining airworthiness standards. This legislative framework ensures that CASA, as the national airworthiness authority, can effectively mandate safety requirements in response to directives issued by other states, thereby enhancing overall aviation safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products to ensure the safety of air navigation. These directives, which are legislative instruments, serve as a key mechanism for maintaining the continuing airworthiness of aircraft types. Each AD applies to the relevant aircraft registered in Australia and mandates compliance with the directives issued by the State of Design. For instance, CASA has issued Australian AD/BELL 427/5 in response to an AD from Transport Canada concerning Bell 427 helicopters, reflecting Australia's commitment to international aviation safety standards under the Convention on International Civil Aviation. These directives do not require public consultation or a Regulatory Impact Statement, as they are issued to meet international obligations and regulatory requirements. The issuance of these ADs is conducted by designated CASA officials in accordance with the statutory framework provided by the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to make regulations that are essential for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifies that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) concerning certain types of aircraft or aeronautical products. These ADs, as per subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus are legislative instruments as per section 6 of the Legislative Instruments Act 2003. This regulatory framework ensures that the continuing airworthiness of aircraft is maintained in accordance with international standards.
The obligations imposed by these provisions on CASA and other entities are significant. CASA, as Australia’s national airworthiness authority, must ensure that the continuing airworthiness of aircraft on the Australian Register is maintained. This involves assessing information from the State of Design and, if necessary, issuing corresponding ADs to mandate the required safety measures. The State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must comply with the ADs issued by CASA to ensure that all aircraft operate within safe parameters. Additionally, the State of Design has the responsibility to provide necessary information to maintain the airworthiness of the aircraft type, which is a critical component of international aviation safety protocols.
Failure to comply with the requirements set out in the ADs can lead to serious consequences. Civil Aviation Act 1988 does not specify exact penalties for breaches, but non-compliance with airworthiness directives can result in severe civil and criminal penalties. For instance, operating an aircraft that does not meet the standards set by an AD could lead to the aircraft being grounded, fines, or even imprisonment. CASA has the authority to enforce these regulations, and the consequences for non-compliance can be significant, impacting both the operator and the manufacturer.
In the specific case of AD/BELL 427/5 issued by CASA, which corresponds to Transport Canada’s AD CD-2003-11 for Bell 427 helicopters, the directive became effective on 28 September 2006. Given that this AD was issued in response to international obligations and the need to align with the State of Design's requirements, no public consultation was conducted, and the Office of Regulatory Review determined that it did not require a Regulatory Impact Statement. This AD was 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. This process highlights the streamlined approach taken to ensure that international safety standards are swiftly and effectively implemented within the Australian regulatory framework.
