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/BEECH 35/34 affecting Beechcraft turbocharged 35 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 35/34. The cancellation will become effective on 8 May 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 was enacted to provide a legal framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation and operations. The Act empowers the Governor-General to make regulations to support these objectives, which is reflected in the Civil Aviation Safety Regulations 1998. Under this regulatory framework, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) to mandate safety standards and ensure the continuing airworthiness of aircraft registered in Australia. This legislative approach is designed to align Australia’s regulatory practices with international standards, particularly those set by the Convention on International Civil Aviation, and to maintain the safety of air navigation within Australia. CASA’s role includes assessing information from the State of Design and, if necessary, issuing Australian ADs to enforce compliance with international safety directives.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for ensuring the safety of air navigation in Australia, with the Civil Aviation Safety Authority (CASA) as the national airworthiness authority. Under section 98 of the Civil Aviation Act, the Governor-General can make regulations for air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations allows CASA to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments that ensure compliance with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, in this case Australia, must implement the necessary requirements to maintain airworthiness. CASA's role includes assessing and, if necessary, issuing Australian ADs to enforce the safety mandates of the State of Design. The issuance and cancellation of such ADs, such as the recent cancellation of AD/BEECH 35/34 for turbocharged 34 model aircraft, are made in accordance with the Act and do not typically require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations that support the Act and ensure the safety of air navigation. Within this framework, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as a mechanism to ensure that aircraft remain airworthy and comply with safety standards. According to subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus they are classified as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations on the parties involved, particularly CASA, include the responsibility to assess any ADs issued by the State of Design concerning aircraft types registered in Australia. CASA must ensure that these ADs are aligned with international standards and, if necessary, issue corresponding Australian ADs to enforce the required safety measures. This obligation extends to ensuring that the continuing airworthiness of each aircraft is maintained by the State of Registry, in line with the principles outlined in Annex 8 of the Convention on International Civil Aviation.
In terms of compliance and enforcement, the Act and the accompanying regulations outline specific consequences for breaches. While the specific details of penalties for non-compliance with ADs are not provided in the excerpt, it is clear that the failure to adhere to these directives could result in civil or criminal penalties. Such penalties may include fines, imprisonment, or other sanctions, depending on the severity of the breach and the jurisdiction in which it occurs. The exact penalties would be detailed in relevant sections of the Civil Aviation Act 1988 and other pertinent legislation.
The process of issuing and cancelling ADs, as demonstrated with the Beechcraft turbocharged 35 model aircraft, underscores the dynamic nature of air safety regulations. CASA's role in assessing and potentially cancelling an AD, such as AD/BEECH 35/34, highlights the agency's commitment to ensuring that only necessary and relevant safety directives remain in effect. In this instance, the cancellation of AD/BEECH 35/34 was a direct result of the aircraft no longer posing a safety risk, and no further action was required as the unsafe condition had been resolved.
