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.
The Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 303/10 affecting Cessna T303 model aeroplanes modified in accordance with Cessna Service Bulletin (SB) No. MEB88-3. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 303/10. The cancellation will become effective on 25 September 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 Manager, Systems and New Technologies, in the Airworthiness Engineering Group, 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 ensure the safety of air navigation and the continuing airworthiness of aircraft within Australia. This Act grants the Governor-General the authority to make regulations under section 98, which are pivotal in maintaining the safety standards required for air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, ensuring compliance with international standards and obligations under the Convention on International Civil Aviation. The ADs serve as a crucial mechanism for maintaining the airworthiness of aircraft, and their issuance and cancellation, such as the recent cancellation of AD/CESSNA 303/10 for Cessna T303 model aeroplanes, reflect Australia’s commitment to international obligations and safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively provide the legislative framework for the issuance and management of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation and the continuing airworthiness of aircraft. The Act empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs, which are legislative instruments, are crucial in maintaining the safety standards of aircraft and aeronautical products in line with international obligations under the Convention on International Civil Aviation. The State of Design holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the airworthiness of individual aircraft. CASA has the authority to issue and cancel ADs, as demonstrated by the cancellation of AD/CESSNA 303/10 for Cessna T303 model aeroplanes, which was subsequently cancelled due to the resolution of the unsafe condition. The cancellation was made without public consultation as it aligned with Australia’s international obligations, and no Regulatory Impact Statement was required. The AD was issued by CASA in accordance with the Civil Aviation Act 1988, reflecting the comprehensive regulatory approach to air safety.
Key Provisions
The Civil Aviation Act 1988, in section 98, empowers the Governor-General to create regulations that enhance the safety of air navigation. Pursuant to regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are crucial for maintaining the safety and airworthiness of aircraft, and as stated in subregulation 39.001(5), they are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, classifying them as legislative instruments. This regulatory framework is designed to ensure that the standards set by the Convention on International Civil Aviation, particularly those outlined in Annex 8, are adhered to by the State of Design and the State of Registry.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on the parties involved are significant. The State of Design, which is responsible for the design of the aircraft, must provide all necessary information to the appropriate State of Registry to ensure the aircraft’s continuing airworthiness. Similarly, the State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements that ensure the ongoing airworthiness of the aircraft. CASA, acting on behalf of the Australian government, issued AD/CESSNA 303/10 for Cessna T303 model aeroplanes modified in accordance with Cessna Service Bulletin No. MEB88-3. After assessing the situation, CASA has cancelled AD/CESSNA 303/10, effective from 25 September 2008, as the unsafe condition no longer exists. This cancellation reflects the commitment to maintaining the highest safety standards in accordance with international obligations.
Failure to comply with the provisions of the Civil Aviation Safety Regulations 1998 and the directives issued under them may result in various consequences. The Act and Regulations do not explicitly outline specific offences or penalties for non-compliance with ADs, but such breaches can potentially lead to civil or criminal liability. Non-compliance could result in severe safety risks, including aircraft accidents, which could lead to prosecution under broader aviation safety laws. Additionally, any legislative instrument made under the Act, such as an AD, is subject to disallowance by either house of Parliament, which can further enforce compliance through legislative scrutiny.
In summary, the Civil Aviation Safety Regulations 1998 and the associated ADs are integral to maintaining the safety and airworthiness of aircraft in Australia. The obligations on the State of Design and the State of Registry are clear, with CASA playing a pivotal role in issuing and managing these directives. The cancellation of AD/CESSNA 303/10 underscores the dynamic nature of these regulations, adapting to evolving safety standards and conditions. Compliance with these directives is crucial to avoid potential civil or criminal consequences, thereby ensuring the continued safety of air navigation.
