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 United States FAA has issued AD 2008-10-06 affecting Boeing 747-400 series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B747/378, which will become effective on 3 July 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, Systems and New Technologies 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 framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act grants the Governor-General the authority to make regulations under section 98, which are aimed at enhancing the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail the procedures for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The policy objective is to ensure the continuing airworthiness of aircraft in accordance with international standards set by the International Civil Aviation Organization (ICAO). When a State of Design issues an AD, CASA must assess it and, if necessary, issue an Australian AD to mandate the requirements, fulfilling Australia's obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) to ensure the safety of air navigation in Australia. Specifically, regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs, being legislative instruments under the Legislative Instruments Act 2003, mandate compliance to maintain the continuing airworthiness of aircraft as per international standards set out in Annex 8 to the Convention on International Civil Aviation. The Act applies to CASA as Australia’s national airworthiness authority and is responsible for assessing ADs issued by the State of Design and issuing corresponding Australian ADs where necessary. While ADs are crucial for compliance with international obligations, they do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This legislative framework ensures that Australian aviation remains aligned with global safety standards, reflecting the shared responsibility of the State of Design and the State of Registry in maintaining aircraft airworthiness.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to establish regulations that align with the Act's objectives, focusing on the safety of air navigation. Within this framework, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), ADs are considered disallowable instruments as per section 46A of the Acts Interpretation Act 1901, and they are classified as legislative instruments under section 6 of the Legislative Instruments Act 2003. This classification underscores their formal status and regulatory authority.
The obligations imposed by the Act and its associated regulations primarily rest on the States of Design and Registry. The State of Design, responsible for the design of an aircraft type, is tasked with ensuring the continuing airworthiness of that type and must provide necessary information to the States of Registry, as mandated by Annex 8 to the Convention on International Civil Aviation. Correspondingly, the State of Registry, which in this case is Australia, must develop or adopt requirements to maintain the continuing airworthiness of aircraft registered within its jurisdiction. When the State of Design issues an AD, CASA, as Australia's national airworthiness authority, is required to evaluate this information and, if necessary, issue an Australian AD to enforce the requirements set forth by the State of Design.
Failure to comply with the provisions of the ADs could result in serious legal and safety repercussions. The Civil Aviation Safety Regulations 1998, along with the overarching Civil Aviation Act 1988, may include specific provisions for non-compliance. Generally, breaches of airworthiness directives could lead to significant penalties, including fines and potential criminal charges. The exact penalties are often outlined within the regulations themselves, but they can be severe, reflecting the critical importance of adhering to airworthiness standards to ensure public safety in aviation. The seriousness of these consequences underscores the mandatory nature of compliance with ADs and the regulatory oversight by CASA.
