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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/CESSNA 320/20 affecting Cessna 320 aeroplanes in 1974. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 24 September 2009. No replacement AD is required.
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, Initial Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a regulatory framework for civil aviation, with a focus on ensuring the safety of air navigation. The Act grants the Governor-General the authority to make regulations, such as the Civil Aviation Safety Regulations 1998, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to maintain the safety standards of aircraft and aeronautical products. These ADs are legislative instruments that serve as a critical means of ensuring the continuing airworthiness of aircraft types, as mandated by the Convention on International Civil Aviation. The cancellation of AD/CESSNA 320/20, affecting Cessna 320 aeroplanes, exemplifies how CASA adheres to international obligations, thus fulfilling its role in maintaining aviation safety within Australia.
The Civil Aviation Safety Regulations 1998, established under the Civil Aviation Act 1988, allow CASA to issue ADs, which are essential for maintaining the airworthiness of aircraft and aeronautical products. The cancellation of AD/CESSNA 320/20, effective from 24 September 2009, highlights CASA's commitment to international aviation standards as stipulated in the Convention on International Civil Aviation. Given the nature of ADs as legislative instruments, no public consultation was deemed necessary for this cancellation, and the Office of Best Practice Regulation confirmed that a Regulatory Impact Statement was not required. This action underscores CASA's role in ensuring that Australia's aviation safety regulations align with global standards.
Scope and Application
The Civil Aviation Act 1988, alongside the Civil Aviation Safety Regulations 1998, establishes the framework for ensuring the safety of air navigation in Australia, with a particular focus on the issuance of airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue these directives, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs serve as a critical mechanism for maintaining the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, where the aircraft is designed, bears the primary responsibility for ensuring continuing airworthiness, while the State of Registry, in this case Australia, is tasked with ensuring that individual aircraft meet airworthiness standards. CASA has historically issued and periodically reviewed such directives, as evidenced by the AD/CESSNA 320/20 affecting Cessna 320 aeroplanes, which was subsequently cancelled on 24 September 2009 due to obligations under the Convention on International Civil Aviation. Given the international scope and nature of these regulations, public consultation and regulatory impact statements are not required for ADs, reflecting their technical and safety-focused purpose.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, allows the Governor-General to create regulations that ensure the safety of air navigation (section 98). According to regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) states that an AD is considered a disallowable instrument under the Acts Interpretation Act 1901, and as such, it is a legislative instrument under the Legislative Instruments Act 2003 (section 6). Annex 8 to the Convention on International Civil Aviation stipulates that the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry to ensure the aircraft's ongoing airworthiness. In this context, ADs serve as a primary means of continuing airworthiness information and are issued by most ICAO Contracting States. Additionally, the State of Registry of an individual aircraft holds the responsibility for its continuing airworthiness and must develop or adopt requirements to ensure the aircraft remains airworthy under Annex 8.
The obligations and requirements imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on the parties involved include the responsibility of the State of Design to provide necessary information to the States of Registry to ensure the continuing airworthiness of an aircraft type. This responsibility extends to the requirement of providing information under Annex 8 to the Convention on International Civil Aviation. Furthermore, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. CASA, acting on behalf of the State of Registry, has the authority to issue ADs for specific types of aircraft or aeronautical products to meet these obligations and requirements. CASA's issuance of ADs is conducted in accordance with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, specifically under subsection 84A(2) of the Act.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences, penalties, or civil/criminal consequences for breach in relation to the issuance of ADs. However, the issuance of ADs is a regulatory process aimed at ensuring the safety of air navigation and the continuing airworthiness of aircraft. Any failure to comply with ADs or the obligations and requirements imposed by the Act and the Regulations could potentially lead to enforcement actions by CASA or other regulatory authorities. Such actions may include the imposition of fines, revocation of airworthiness certificates, or other regulatory measures to ensure compliance with safety regulations. The exact consequences for non-compliance would depend on the specific circumstances and the applicable provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998.
