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 US FAA has issued AD 2005-06-12 affecting Boeing 747 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/281 Amendment 1 which will become effective on 7 July 2005. This AD cancels and replaces the previous issue.
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 was enacted to establish a comprehensive legal framework for civil aviation in Australia, ensuring the safety, efficiency, and orderly growth of aviation activities. The Act empowers the Governor-General to make regulations in the interests of the safety of air navigation, with the Civil Aviation Safety Regulations 1998 further detailing the requirements for maintaining airworthiness of aircraft and aeronautical products. This legislative framework is integral to fulfilling Australia's obligations under the Convention on International Civil Aviation, particularly concerning the continuing airworthiness of aircraft types. The Civil Aviation (Airworthiness Directives) Regulations 2005, as represented by the instrument F2005L01351, illustrate the mechanism by which the Civil Aviation Safety Authority (CASA) issues airworthiness directives in response to international mandates, ensuring alignment with global safety standards while maintaining the safety of air navigation within Australia.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, establish a comprehensive framework for ensuring the safety of air navigation in Australia. The Act empowers the Governor-General to make regulations necessary for safety, with specific provisions allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs serve as legislative instruments, designed to mandate requirements necessary for maintaining the continuing airworthiness of aircraft, in line with international standards set forth by the Convention on International Civil Aviation. The application of these regulations extends to all aircraft registered in Australia, irrespective of their origin, ensuring that both domestic and foreign aircraft comply with Australian safety standards. Exemptions or exclusions from these requirements are not detailed in the provided text, but it is implied that they would be assessed on a case-by-case basis by CASA. The scope of these regulations is further extended through subordinate instruments, allowing for the detailed specification of airworthiness standards and mandates.
Key Provisions
The main operative sections of the Civil Aviation Regulations 1998 pertinent to the issue of airworthiness directives (ADs) are sections 39.001 (subsection 5) and 84A (subsection 2). Section 39.001(5) explicitly states that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and by extension, a legislative instrument under section 6 of the Legislative Instruments Act 2003. This section clarifies the legal status of ADs, ensuring they are recognised and treated as formal regulatory instruments. Section 84A(2) outlines the authority under which CASA can issue such directives, aligning with the requirements set out by the Civil Aviation Act 1988.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose specific obligations on CASA and other parties involved in the issuance and compliance with ADs. CASA, as the national airworthiness authority, must assess ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs. This ensures that Australian-registered aircraft meet international safety standards. The State of Registry is responsible for implementing these ADs and ensuring the continuing airworthiness of aircraft within its jurisdiction. These obligations are rooted in international obligations under the Convention on International Civil Aviation, particularly Annex 8, which designates the State of Design and State of Registry with specific responsibilities.
The legislation does not explicitly outline offences or penalties for non-compliance with ADs within the text provided. However, the gravity of airworthiness issues implies that failure to comply with ADs could lead to severe consequences, including potential aircraft grounding, prosecution, and hefty fines. The specifics of penalties would likely be addressed in other sections of the Civil Aviation Act 1988 or related regulations, which are not detailed in the provided text. Given the critical nature of air safety, non-compliance could also result in severe civil liabilities and potentially criminal charges if the non-compliance leads to accidents or endangers lives.
In summary, the Civil Aviation Regulations 1998 and related acts provide a clear framework for the issuance and enforcement of airworthiness directives to ensure the safety of air navigation. CASA's role in assessing and issuing ADs is crucial, and the responsibilities of States of Design and Registry are clearly defined under international conventions. The legal status of ADs as legislative instruments underscores their importance and enforceability.
