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 180/42 affecting Cessna 180J aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 180/42. The cancellation will become effective on 13 March 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, is the primary legislation governing civil aviation in Australia. It was introduced to ensure the safety and efficiency of air navigation within Australian territory, and to fulfil Australia’s international obligations under the Convention on International Civil Aviation. The Act empowers the Governor-General to create regulations in the interest of air navigation safety, with a focus on continuing airworthiness of aircraft and aeronautical products. The Civil Aviation Safety Regulations 1998, made under the Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, which are legally binding legislative instruments designed to address safety concerns and maintain airworthiness standards. These directives are crucial for ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO). CASA, as Australia’s national airworthiness authority, plays a pivotal role in assessing and issuing these directives, thereby upholding both domestic and international safety requirements.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations apply to all aircraft and aeronautical products registered in Australia, ensuring that safety standards are maintained in alignment with international obligations under the Convention on International Civil Aviation. Specifically, the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure that aircraft within Australia meet the necessary safety standards by issuing or adopting ADs as required. The ADs serve as legislative instruments, subject to disallowance under the Acts Interpretation Act 1901, and are intended to address safety issues by mandating corrective actions or modifications to aircraft types registered in Australia. In the specific instance of AD/CESSNA 180/42, CASA assessed the AD issued by the State of Design and, finding that the unsafe condition no longer exists, decided to cancel the Australian AD effective 13 March 2008, without the need for a replacement directive. This decision was made in accordance with the relevant statutory provisions and does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The key provisions of the Civil Aviation Act 1988, as they relate to the issuance of airworthiness directives (ADs), can be found in section 98, which empowers the Governor-General to make regulations to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further provides that the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products. The Civil Aviation Safety Regulations 1998, under subregulation 39.001(5), stipulate that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, as per section 6 of the Legislative Instruments Act 2003, ADs are classified as legislative instruments. This means that ADs have the force of law and must be issued in accordance with the statutory framework.
The obligations imposed by these provisions on CASA and other entities primarily revolve around ensuring the continuing airworthiness of aircraft. Under Annex 8 to the Convention on International Civil Aviation, the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure its airworthiness to appropriate States of Registry. In Australia, CASA, as the national airworthiness authority, is tasked with assessing the information provided by the State of Design and, if necessary, issuing an Australian AD to mandate the requirements of the State of Design. This ensures that the Australian Register complies with international safety standards. The State of Registry of an individual aircraft must also develop or adopt requirements to ensure the continuing airworthiness of the aircraft.
There are significant consequences for non-compliance with ADs, though the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail penalties for breaching these specific provisions. Generally, non-compliance with ADs can lead to severe penalties, including fines and imprisonment for individuals, as well as potential liability for civil suits. The seriousness of these consequences underscores the importance of adhering to the ADs to maintain the safety of air navigation. CASA’s assessment and subsequent cancellation of Australian AD/CESSNA 180/42 for Cessna 180J aircraft, effective from 13 March 2008, exemplifies how ADs are managed to address unsafe conditions and ensure compliance with international obligations.
