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 French DGAC has issued AD 80-250-21(B) affecting SA 315 model helicopters. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/SA 315/12, which will become effective on 23 November 2006.
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, establishes the framework for the regulation of civil aviation in Australia, aiming to ensure safety and efficiency in air navigation. The Act empowers the Governor-General to create regulations that serve the interests of air navigation safety, with the Civil Aviation Safety Regulations 1998 being a key component of this framework. These regulations provide the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products to maintain the continuing airworthiness of aircraft. This legislative structure was designed to align with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation, ensuring that Australia meets its obligations as both a State of Registry and Design. The objective is to ensure that all aircraft operating in Australian airspace adhere to the highest safety standards, as determined by CASA in consultation with international aviation authorities.
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. These directives are issued to ensure compliance with safety standards and regulations in the interests of air navigation safety. As legislative instruments, ADs are subject to disallowance provisions outlined in the Acts Interpretation Act 1901 and are regulated under the Legislative Instruments Act 2003. The application of these ADs is both national and international, as they are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has the responsibility for the continuing airworthiness of aircraft types and must provide necessary information to States of Registry, including Australia. CASA, as Australia’s national airworthiness authority, is required to assess information from the State of Design and issue corresponding Australian ADs when necessary. Exemptions or thresholds for AD issuance are not specified in the provided text, but the process does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, outlines the framework for ensuring the safety of air navigation in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations for the Act's purposes, particularly for enhancing the safety of air navigation. Regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. Importantly, these ADs are legislative instruments under section 46A of the Acts Interpretation Act 1901 and are thus subject to disallowance procedures.
The obligations imposed by these regulations are substantial. The State of Design, which is the country where the aircraft type is designed, has the overarching responsibility for ensuring the continuing airworthiness of the aircraft. This responsibility includes providing necessary information to the States of Registry, which are the countries where the individual aircraft are registered. CASA, as Australia's national airworthiness authority, must assess the ADs issued by States of Design and, if deemed necessary, issue corresponding Australian ADs to enforce the design state’s requirements. This ensures that Australian-registered aircraft meet international safety standards.
Failure to comply with the ADs can have significant legal consequences. Although the ADs themselves do not require public consultation or a Regulatory Impact Statement, their issuance is critical to maintaining safety standards. Any breaches of ADs can lead to serious penalties. Civil penalties may include fines, and criminal penalties can include imprisonment, reflecting the gravity of ensuring aviation safety. The ADs are issued by authorised personnel within CASA, ensuring that the process adheres to the statutory requirements set forth in the Act.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for ensuring the safety of air navigation through the issuance and enforcement of airworthiness directives. These instruments place significant responsibilities on both the State of Design and the State of Registry, with CASA acting as the national authority responsible for assessing and implementing these directives. Compliance is mandatory, and any breaches can result in serious civil and criminal penalties, underscoring the importance of these regulations in maintaining aviation safety standards.
