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 European Aviation Safety Agency (EASA) has issued AD 2006-0055-E affecting AS 350 B, AS 350 BA, AS 350 BB, AS 350 B1, AS 350 B2, AS 350 B3 and AS 350 D rotorcraft. France is the State of Design for this type and is a member of the European Union. CASA has assessed this AD and has issued Australian AD/ECUREUIL/117, which will become effective on 6 March 2006.
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 by the Parliament of Australia to provide a legislative framework for the regulation of civil aviation within the country, primarily to ensure the safety of air navigation. In line with this overarching objective, the Civil Aviation Safety Regulations 1998 were established to detail specific safety requirements. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations that serve the Act’s purposes and the interests of air navigation safety. Under these regulations, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. The Civil Aviation Safety Regulations 1998 further clarify that ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. This legislative framework ensures that Australia adheres to its international obligations under the Convention on International Civil Aviation, particularly concerning the continuing airworthiness of aircraft types, a responsibility primarily borne by the State of Design. CASA, as Australia’s national airworthiness authority, plays a crucial role in assessing and, if necessary, issuing ADs to mandate the requirements of the State of Design.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, provide for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. These directives are legislative instruments that apply to specific kinds of aircraft or aeronautical products registered in Australia. The ADs are necessary to maintain the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation and the requirements set by the aircraft's State of Design. CASA, acting as Australia's national airworthiness authority, must assess and, if appropriate, issue Australian ADs that reflect the directives issued by the relevant State of Design, ensuring compliance and safety standards are uniformly upheld across the Australian aviation sector. The issuance of these directives is executed without public consultation as they are directly responsive to international safety standards and obligations.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the regulation of civil aviation safety in Australia, with particular emphasis on the issuance and enforcement of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to create regulations for air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), an AD is considered a disallowable instrument under the Acts Interpretation Act 1901, and as such, it falls under the purview of the Legislative Instruments Act 2003.
The obligations imposed by this legislation are multifaceted. Firstly, the State of Design—the country where the aircraft type is designed—has the overarching responsibility for ensuring the continuing airworthiness of the aircraft type, in accordance with Annex 8 to the Convention on International Civil Aviation. This includes providing necessary information to the States of Registry to maintain airworthiness. Secondly, the State of Registry, which in Australia is CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD for an aircraft type registered in Australia, CASA must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements stipulated by the State of Design.
Failure to comply with the provisions of an AD can lead to significant legal consequences. Under section 84A of the Act, CASA can impose penalties for non-compliance with airworthiness directives. These penalties may include fines, imprisonment, or both, depending on the severity of the breach. The exact penalties are not specified in the provided text, but it is clear that strict adherence to ADs is mandatory to maintain safety standards in civil aviation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 mandate that CASA issue airworthiness directives to ensure the safety of aircraft in Australia. The State of Design is responsible for issuing initial ADs, which CASA must then assess and potentially enforce as Australian ADs. Failure to comply with these directives can result in severe penalties, underscoring the critical importance of adhering to airworthiness standards.
