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 US FAA has issued AD 2007-01-10 affecting Boeing B747 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/315, Amendment 1, which will become effective on 15 March 2007. 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 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, enacted by the Australian Parliament, serves as the foundational legal framework for ensuring the safety and efficiency of civil aviation in Australia. In 1998, the Civil Aviation Safety Regulations were introduced to provide further detail and enforce compliance with safety standards. One significant aspect of these regulations is the issuance of airworthiness directives (ADs) under regulation 39.001, which are legislative instruments used to address safety issues concerning aircraft and aeronautical products. The Civil Aviation Safety Authority (CASA), as the national airworthiness authority, is tasked with issuing these ADs in accordance with international standards, particularly those set by the Convention on International Civil Aviation. This ensures that Australia meets its obligations under international agreements and maintains the safety of its airspace. The ADs are issued in response to directives from the State of Design or other contracting states, as mandated by Annex 8 of the Convention, and are enforced to uphold the continuing airworthiness of aircraft registered in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products, ensuring the ongoing safety and airworthiness of these aircraft within Australia. This regulation applies to all aircraft registered in Australia and is intended to ensure compliance with international standards set by the International Civil Aviation Organization (ICAO). As such, it covers all aircraft operators, manufacturers, and other entities involved in the operation and maintenance of aircraft within Australian jurisdiction. The application of these regulations is not limited to Australian territory; they extend to all aircraft registered in Australia regardless of where they are located or operated internationally, ensuring that Australian standards are upheld globally. While the ADs are legislative instruments that must be assessed and potentially adopted by CASA, they are not subject to public consultation or regulatory impact statements, given their alignment with international safety obligations and the necessity of rapid response to safety concerns raised by the State of Design.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Under these provisions, the Civil Aviation Safety Regulations 1998 (regulation 39.001) allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, as outlined in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, they qualify as legislative instruments under section 6 of the Legislative Instruments Act 2003. The ADs are essential tools for maintaining the airworthiness of aircraft types, as they provide necessary information to ensure their continued safe operation, in accordance with Annex 8 of the Convention on International Civil Aviation.
The responsibilities of the State of Design and the State of Registry are clearly defined in the Convention on International Civil Aviation. The State of Design, in this case, the United States for Boeing B747 model aircraft, holds the overall responsibility for the continuing airworthiness of the aircraft type and must furnish any information required to ensure this airworthiness to the appropriate States of Registry. Conversely, the State of Registry, represented by CASA in Australia, is tasked with the responsibility of ensuring the continuing airworthiness of individual aircraft. This involves developing or adopting requisite measures and, in the case of an AD issued by the State of Design, assessing the information and, if necessary, issuing an Australian AD to enforce the State of Design's requirements. This ensures that Australian-registered aircraft meet international safety standards.
The obligations placed on parties governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are substantial. CASA, as Australia's national airworthiness authority, must act swiftly and efficiently in assessing and responding to ADs issued by the State of Design. This includes cancelling and replacing previous ADs with updated information, as seen with AD/B747/315, Amendment 1, which replaced the previous directive and is set to become effective on 15 March 2007. The State of Registry is also obligated to ensure that all aircraft under its registry comply with the ADs issued, thereby maintaining the highest safety standards in accordance with international conventions.
In terms of legal consequences, any breach of the requirements outlined in the ADs can lead to severe penalties and consequences. While the specific penalties are not detailed in the provided text, it is known that non-compliance with airworthiness directives can result in civil or criminal penalties, including fines and potential imprisonment. The severity of these penalties underscores the importance of adhering to the ADs, which are designed to safeguard the safety of air navigation. The rigorous assessment process and the legal framework in place reflect the high stakes involved in ensuring the airworthiness of aircraft.
