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 UK CAA has issued AD G-2005-0020 affecting BAe 146 and Avro RJ model aircraft. The UK is the State of Design for these types. CASA has assessed this AD and as a result has cancelled Australian AD/BAE 146/1. The cancellation will become effective on 29 September 2005. No replacement AD is required, as the original unsafe condition has been corrected by AD/BAe 146/36 Amendment 1.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, and because it is cancelled in response to an AD raised by the relevant State of Design, no consultation with the Australian public has taken place on this AD cancellation. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes 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 regulate civil aviation in Australia and to ensure the safety of air navigation. In this context, the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs), which are critical for maintaining the safety and airworthiness of aircraft. ADs are legislative instruments, as outlined in the Legislative Instruments Act 2003, and are essential for ensuring compliance with international standards set by the Convention on International Civil Aviation. The Civil Aviation (Safety) Regulations 1998 mandate that the State of Design for an aircraft type is responsible for issuing ADs, and the State of Registry, such as CASA in Australia, must then assess and implement these directives to maintain the continuing airworthiness of aircraft registered in Australia. This legislative framework ensures that all necessary safety measures are communicated and enforced, thereby protecting public safety in civil aviation.
Scope and Application
The Civil Aviation Act 1988, as supported by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia, ensuring the ongoing safety and airworthiness of aircraft. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products, with these directives being legislative instruments under the Legislative Instruments Act 2003. The Act applies to entities involved in the operation and maintenance of aircraft registered in Australia, including airlines, aircraft manufacturers, and maintenance organisations. Its jurisdiction extends nationally, with CASA as Australia's national airworthiness authority responsible for implementing and enforcing these directives. International obligations under the Convention on International Civil Aviation further inform the process, as Australia must align with directives issued by the State of Design, which in the case of BAe 146 and Avro RJ models, is the UK. This alignment can result in the cancellation or amendment of existing Australian ADs, as exemplified by the cancellation of Australian AD/BAE 146/1 in response to UK AD G-2005-0020. This cancellation, aligned with international standards, does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory provision is grounded in section 98 of the Civil Aviation Act 1988, which allows the Governor-General to make regulations to ensure the safety of air navigation. Moreover, subregulation 39.001(5) stipulates that an AD is a disallowable instrument as per section 46A of the Acts Interpretation Act 1901, and thus, in line with section 6 of the Legislative Instruments Act 2003, an AD qualifies as a legislative instrument. This legislative framework ensures that ADs, which are essential for maintaining the continuing airworthiness of aircraft, are issued in accordance with international standards and obligations.
The Civil Aviation Safety Regulations 1998 mandate that the State of Design has primary responsibility for the continuing airworthiness of an aircraft type, and it must provide necessary information to the States of Registry to ensure ongoing compliance with safety standards. The State of Registry, in turn, is responsible for the airworthiness of individual aircraft and must develop or adopt requisite measures to maintain this standard. When the State of Design issues an AD, CASA, as Australia's national airworthiness authority, is required to assess this information and, if appropriate, issue an Australian AD to enforce the State of Design's requirements. This collaborative approach ensures that safety directives are uniformly applied across jurisdictions, reflecting international best practices.
Under these regulations, CASA has assessed a UK Civil Aviation Authority (CAA) AD G-2005-0020, which affects BAe 146 and Avro RJ model aircraft. As the UK is the State of Design for these aircraft types, CASA has determined that Australian AD/BAe 146/1 should be cancelled. This cancellation, effective from 29 September 2005, was made in response to the original unsafe condition being corrected by AD/BAe 146/36 Amendment 1. Given that the AD cancellation aligns with Australia's obligations under the Convention on International Civil Aviation and is in response to an AD issued by the relevant State of Design, no consultation with the Australian public was necessary. Furthermore, the Office of Regulatory Review has concluded that ADs do not require a Regulatory Impact Statement.
In the context of civil aviation, it is important to note the legal consequences of non-compliance with airworthiness directives. Under the Civil Aviation Act 1988, failure to comply with an AD can result in significant penalties. For instance, individuals found guilty of contravening an AD may face fines of up to $22,235 for individuals and $111,175 for corporations, as stipulated in section 98 of the Act. Additionally, CASA has the authority to take enforcement actions, including grounding non-compliant aircraft and imposing operational restrictions, to ensure the safety of air navigation. These stringent measures underscore the importance of adhering to airworthiness directives to maintain the highest standards of aviation safety.
