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 Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 310/6 affecting Cessna 310 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 310/6. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting 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, enacted by the Australian Parliament, establishes the framework for ensuring the safety of air navigation within Australia. This legislation empowers the Governor-General to create regulations under section 98, which are critical for maintaining the safety standards of air navigation. The Civil Aviation Safety Regulations 1998, which complement the Act, provide specific provisions such as enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs, which are legislative instruments as per the Legislative Instruments Act 2003, play a vital role in ensuring the continuing airworthiness of aircraft, in line with international obligations under the Convention on International Civil Aviation. CASA, acting as Australia’s national airworthiness authority, assesses information from the State of Design and issues appropriate ADs to mandate necessary safety measures. The authority to cancel ADs, as seen with the recent cancellation of AD/CESSNA 310/6, underscores the dynamic nature of airworthiness regulation, ensuring that safety standards are continually met and maintained.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives in Australia, ensuring the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for certain types of aircraft or aeronautical products. These directives are legislative instruments that are subject to disallowance under the Acts Interpretation Act 1901 and are regulated by the Legislative Instruments Act 2003. The State of Design, typically the country where the aircraft type is designed, bears primary responsibility for the continuing airworthiness of an aircraft type under Annex 8 to the Convention on International Civil Aviation, with the State of Registry, in this case, Australia, responsible for ensuring the airworthiness of specific aircraft registered within its territory. When a State of Design issues an airworthiness directive, CASA must assess the information and, if appropriate, issue an Australian airworthiness directive to enforce the requirements. The AD/CESSNA 310/6, affecting Cessna 310 aircraft, is an example where CASA issued and subsequently cancelled such a directive due to changes in the unsafe condition identified. This action aligns with Australia’s obligations under the Convention on International Civil Aviation, and as such, no public consultation was necessary. Additionally, the Office of Best Practice Regulation has determined that airworthiness directives do not require a Regulatory Impact Statement. The cancellation of AD/CESSNA 310/6 was executed by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework under which airworthiness directives (ADs) are issued in Australia. Under section 98 of the Act, the Governor-General is empowered to create regulations aimed at ensuring the safety of air navigation, and regulation 39.001 of the Regulations specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs are legislative instruments and can be disallowed under section 46A of the Acts Interpretation Act 1901. The ADs are typically issued to address safety issues identified with specific aircraft types and are mandated by the State of Design, which has the overarching responsibility for the continuing airworthiness of the aircraft type.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA and other entities include the assessment and potential issuance of ADs when a State of Design issues one for aircraft on the Australian Register. CASA, as Australia's national airworthiness authority, must review the ADs issued by the State of Design and determine if an Australian AD is necessary to ensure compliance with safety standards. Additionally, under Annex 8 to the Convention on International Civil Aviation, the State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must develop or adopt requirements to ensure the safety of aircraft registered within its jurisdiction. These obligations ensure that safety directives are communicated and implemented effectively across all relevant parties.
Failure to comply with ADs can lead to significant legal consequences. While the specific offences and penalties for non-compliance with ADs are not detailed in the provided text, it is known that breaches of civil aviation regulations can result in both civil and criminal penalties. Under Australian law, civil penalties can include fines, and in severe cases, criminal penalties may apply, which could result in imprisonment. The exact penalties would depend on the specific breach and the severity of the violation, but they are designed to ensure strict adherence to safety regulations to protect the public and maintain the integrity of the aviation system.
