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.
Transport Canada has issued AD CF-2007-02 affecting Bell 206 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 206/167, which will become effective on 8 March 2007.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the safety and efficiency of civil aviation in Australia, including the regulation of airworthiness standards. Under section 98 of this Act, the Governor-General has the authority to make regulations, including issuing airworthiness directives (ADs), to ensure the safety of air navigation. The Civil Aviation Safety Regulations 1998 further elaborate on the regulatory framework, with regulation 39.001 specifically enabling the issuance of ADs for certain types of aircraft or aeronautical products. This regulatory mechanism is essential for maintaining the safety standards required under international conventions such as Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design for an aircraft type must provide necessary information to ensure its continuing airworthiness, a responsibility that CASA, as Australia's national airworthiness authority, must enforce. This legislation ensures that Australia adheres to its international obligations while safeguarding the safety of its airspace.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) in the interests of air navigation safety. These ADs apply to specified types of aircraft or aeronautical products and are legislative instruments under the Legislative Instruments Act 2003. The State of Design for an aircraft type holds the primary responsibility for ensuring its continuing airworthiness, and must provide necessary information to States of Registry, which are responsible for the individual aircraft’s airworthiness. When the State of Design issues an AD, CASA must assess the information and, if appropriate, issue an Australian AD to mandate the requirements. For example, in response to Transport Canada’s AD CF-2007-02 affecting Bell 206 model helicopters, CASA issued AD/BELL 2007/167. Because these ADs are issued pursuant to international obligations and in response to actions by the State of Design, they do not require public consultation or a Regulatory Impact Statement. Instead, the ADs are issued by CASA on behalf of the Australian Government, ensuring compliance with both national and international aviation safety standards.
Key Provisions
The key sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 that pertain to the issue of airworthiness directives (ADs) are sections 98 and 39.001 respectively. Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. Furthermore, under subregulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is therefore a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions include the responsibility of the State of Design, which must provide necessary information to ensure the continuing airworthiness of a type of aircraft, and the State of Registry, which must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. When the State of Design issues an AD, CASA must assess this information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. For example, Transport Canada issued AD CF-2007-02 for Bell 206 model helicopters, and CASA issued Australian AD/BELL 206/167 in response, effective from 8 March 2007.
In terms of breaches, the text does not explicitly outline the offences or penalties for non-compliance with ADs. However, it is reasonable to infer that failure to comply with such directives could result in severe consequences, including potential risks to flight safety and legal penalties. While the specific maximum penalties are not detailed in the text, non-compliance with ADs could lead to enforcement actions by CASA, which may include fines, grounding of aircraft, or other regulatory measures. The severity of these penalties would likely depend on the specific circumstances of the breach and the impact on aviation safety.
