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 US FAA has issued AD 2007-01-09 affecting Boeing B747 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/354, which will become effective on 15 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, enacted by the Australian Parliament, serves as the primary legislative framework governing civil aviation in Australia. This Act was introduced to ensure the safety and efficiency of civil aviation within Australia, aligning with international standards and obligations under the Convention on International Civil Aviation. In particular, the Act facilitates the regulation of air navigation and the issuance of airworthiness directives (ADs) to address potential safety issues in aircraft or aeronautical products. The Civil Aviation Safety Regulations 1998, which complement the Act, empower the Civil Aviation Safety Authority (CASA) to issue ADs as necessary. These directives are critical for maintaining the continuing airworthiness of aircraft registered in Australia, reflecting the State of Registry’s responsibility under Annex 8 of the Convention on International Civil Aviation. The issuance of ADs by CASA ensures compliance with international obligations and addresses safety concerns identified by the State of Design, such as the recent AD issued by the US Federal Aviation Administration affecting Boeing B747 model aircraft.
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) that apply to specific types of aircraft or aeronautical products. These directives are legislative instruments issued under the authority of the Governor-General and are essential for ensuring the continuing airworthiness of aircraft registered in Australia. The scope of these regulations extends to the entire Australian jurisdiction, encompassing both domestic and international civil aviation activities occurring within Australia. ADs are issued in response to safety concerns identified by the State of Design, with CASA acting as Australia's national airworthiness authority to assess and mandate these requirements. While ADs are issued to meet international obligations under the Convention on International Civil Aviation, they are not subject to public consultation or the requirement for a Regulatory Impact Statement, as they are considered a direct response to safety directives from the State of Design.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for the issuance of airworthiness directives (ADs). Specifically, section 98 of the Civil Aviation Act 1988 allows the Governor-General to create regulations in the interest of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs for certain types of aircraft or aeronautical products. Moreover, subregulation 39.001(5) classifies ADs as disallowable instruments under the Acts Interpretation Act 1901, and thus as legislative instruments according to the Legislative Instruments Act 2003.
These regulations impose obligations on CASA to assess and, if necessary, issue Australian ADs in response to ADs issued by the State of Design. This involves evaluating the information provided by the State of Design and ensuring that it aligns with the requirements for continuing airworthiness as outlined in Annex 8 of the Convention on International Civil Aviation. The State of Registry, in this case CASA, must ensure that the aircraft continue to meet airworthiness standards, which includes implementing any necessary ADs. The responsibility to maintain the continuing airworthiness of an aircraft ultimately lies with the State of Registry, which must develop or adopt the necessary requirements to achieve this.
Failure to comply with ADs can lead to significant consequences. Civil aviation regulations often outline specific offences related to non-compliance with ADs, and violations can result in both civil and criminal penalties. For example, under the Civil Aviation Act 1988, non-compliance with an AD can lead to fines, imprisonment, or both, depending on the severity of the violation and the specific provisions of the legislation. CASA has the authority to enforce these regulations and can take action against entities or individuals who fail to comply with ADs, which may include grounding aircraft, imposing fines, or pursuing legal action.
In summary, the legislative framework established by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 ensures that ADs are effectively issued and enforced to maintain the safety and airworthiness of aircraft. CASA plays a pivotal role in this process, ensuring that Australian aircraft comply with international standards and domestic regulations.
