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.
CASA issued AD/CESSNA 340/15, affecting Cessna 340 model aircraft in 1978. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as all affected aircraft would have been inspected, and, if necessary, modified long ago.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. In line with this objective, the Act empowers the Governor-General to create regulations that support the Act's aims and safeguard air navigation safety. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions by allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby maintaining the continuing airworthiness of these aircraft. The ADs serve as a legislative instrument under the Acts Interpretation Act 1901 and are crucial for ensuring that aircraft meet international safety standards as set out in Annex 8 to the Convention on International Civil Aviation. This regulation process ensures that Australia’s national airworthiness authority, CASA, effectively manages and enforces safety standards for aircraft registered within its jurisdiction.
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 specific types of aircraft or aeronautical products. These directives are legislative instruments that must comply with the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are intended to ensure the safety of air navigation and are aligned with international standards as set out in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type. The State of Registry, which is the country where the aircraft is registered, must also ensure the continuing airworthiness by adopting or developing appropriate requirements. For example, when the State of Design issues an AD for a type of aircraft registered in Australia, CASA, as the national airworthiness authority, must assess the information and, if necessary, issue an Australian AD to enforce the requirements. In the case of AD/CESSNA 340/15, affecting Cessna 340 model aircraft from 1978, CASA has decided to cancel this directive as no further action is required for the affected aircraft. This cancellation, effective from 3 July 2008, does not necessitate public consultation or a Regulatory Impact Statement as it results in a reduction of the regulatory burden. The AD cancellation was authorised by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Civil Aviation Act 1988.
Key Provisions
The key operative sections of this legislation are section 98 of the Civil Aviation Act 1988, which empowers the Governor-General to make regulations in the interest of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. Section 39.001(5) of the Regulations further clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus constitutes a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
These provisions outline the framework within which CASA operates to ensure the continuing airworthiness of aircraft registered in Australia. CASA’s role is to assess information provided by the State of Design and, where appropriate, issue Australian ADs to enforce the necessary safety measures. This involves a rigorous process of reviewing and potentially cancelling existing ADs if they are no longer applicable, as was the case with AD/CESSNA 340/15, which affected Cessna 340 model aircraft built in 1978. CASA’s decision to cancel this AD was based on the conclusion that all affected aircraft had already been inspected and modified as necessary, thus making the AD redundant.
The obligations imposed by these regulations are significant for both CASA and aircraft operators. CASA must diligently assess and respond to ADs issued by the State of Design, ensuring that Australian ADs are issued when necessary to maintain airworthiness standards. Aircraft operators, on the other hand, are required to comply with all ADs that apply to their aircraft. This includes adhering to the specified inspection and modification requirements to ensure their aircraft remain airworthy. Failure to comply with an AD can result in severe consequences, including potential grounding of the aircraft and legal repercussions.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose strict penalties for non-compliance with ADs. Violations can result in both civil and criminal penalties. Under the Act, non-compliance with an AD can lead to substantial fines, with the exact amount determined by the seriousness of the breach. Additionally, persistent or egregious non-compliance may result in criminal charges, leading to imprisonment for up to two years. These stringent measures underscore the importance of adhering to ADs to ensure the highest standards of aviation safety.
