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 Italian ENAC has issued AD 2005-484 affecting Agusta-Bell 412 Model helicopters. Italy is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/BELL 412/46, which will become effective on 21 December 2005.
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 Acting 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, enacted by the Australian Parliament, was introduced to regulate civil aviation within Australia, ensuring the safety and efficiency of air navigation. The Act provides the framework for the creation of regulations that pertain to the safety of air navigation, with the overarching goal of maintaining high standards in the aviation industry to protect the public. One such regulation is the Civil Aviation Safety Regulations 1998, which were developed in accordance with the Act and empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various kinds of aircraft or aeronautical products. The ADs are legislative instruments that mandate safety requirements for aircraft, ensuring their continuing airworthiness. This mechanism is crucial for aligning Australia’s aviation safety standards with international obligations, particularly under the Convention on International Civil Aviation, thereby facilitating global air travel safety and cooperation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) within Australia, ensuring compliance with international safety standards. The Act applies to the Civil Aviation Safety Authority (CASA) and other entities involved in the oversight and maintenance of aircraft within the Australian Register. This legislation mandates that CASA, as the national airworthiness authority, must issue ADs when a State of Design issues such directives for aircraft types registered in Australia. Such ADs are legislative instruments that align with the requirements of Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design overall responsibility for the continuing airworthiness of an aircraft type. States of Registry, including CASA, must implement these ADs to ensure the ongoing safety of aircraft. Notably, these regulations do not require public consultation or a Regulatory Impact Statement, reflecting the critical and immediate nature of air safety mandates. The application of these ADs is geographically and jurisdictional bound to Australia, with CASA operating under the authority granted by the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further mandates that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, as detailed in 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.
The obligations under these provisions primarily involve CASA in its role as Australia's national airworthiness authority. When a State of Design, such as Italy for the Agusta-Bell 412 Model helicopters, issues an AD, CASA must review the information and, if necessary, issue a corresponding Australian AD to enforce the State of Design's requirements. This process is integral to ensuring the continuing airworthiness of aircraft registered in Australia, as per the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation.
The Civil Aviation Safety Regulations 1998 impose several requirements on CASA and other relevant entities. CASA must assess the ADs issued by the State of Design and determine the necessity of issuing an Australian AD. Furthermore, States of Registry are required to develop or adopt their own requirements to ensure the continuing airworthiness of aircraft under their registry, adhering to international standards and practices.
Failure to comply with ADs can result in serious consequences. While the specific civil or criminal penalties are not detailed in the provided text, the issuance and enforcement of ADs are critical for maintaining aviation safety standards. Non-compliance could potentially lead to aircraft being grounded, fines, or other regulatory actions, as mandated by the Civil Aviation Act 1988 and associated regulations. These measures are designed to uphold the highest safety standards in Australia's civil aviation sector.
