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 Transport Canada has issued AD CF-2001-14 affecting Bombardier DHC-8-400 series aircraft. Canada is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/DHC-8/116, which will become effective on 13 April 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, New Technologies and Systems, 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 a comprehensive framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the sector. One key aspect of this framework is the issuance of airworthiness directives (ADs), which are regulatory instruments designed to mandate specific actions to ensure the continuing airworthiness of aircraft. Section 98 of the Act empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These directives are essential for maintaining the safety standards required by international conventions such as Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry. Given that ADs are a form of legislative instrument, they are subject to specific legislative processes, including the requirement for disallowance under section 46A of the Acts Interpretation Act 1901.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, provide the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. Regulation 39.001 empowers CASA to issue such directives, which are considered legislative instruments under the Legislative Instruments Act 2003. These directives are integral to ensuring the continuing airworthiness of aircraft, with the State of Design bearing the primary responsibility for this aspect as per Annex 8 to the Convention on International Civil Aviation. The State of Registry, in this case CASA as Australia's national airworthiness authority, must then develop or adopt requirements to ensure the continuing airworthiness of aircraft registered in Australia. When a State of Design, such as Transport Canada in the case of the Bombardier DHC-8-400 series, issues an AD, CASA must evaluate this information and, if necessary, issue a corresponding Australian AD. This process underscores the international nature of aviation safety standards and the necessity for harmonised regulatory measures across different jurisdictions.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation in Australia. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations that safeguard air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Under subregulation 39.001(5), ADs are recognised as disallowable instruments under the Acts Interpretation Act 1901, thereby making them legislative instruments in their own right. This regulatory structure aligns with international standards, particularly Annex 8 of the Convention on International Civil Aviation, which delineates the responsibilities of the State of Design and the State of Registry for the airworthiness of aircraft.
The obligations imposed by the Act and the Regulations are primarily concerned with ensuring the safety and airworthiness of aircraft. The State of Design, such as Canada for Bombardier DHC-8-400 series aircraft, is tasked with providing information to maintain the continuing airworthiness of aircraft types. The State of Registry, in this case CASA for Australia, must evaluate this information and issue corresponding ADs when necessary. This process ensures that Australian aircraft comply with international standards and local regulations, thereby maintaining high safety standards. CASA’s role involves assessing the ADs issued by the State of Design and determining whether they need to be adapted or implemented as Australian ADs.
Failure to comply with the requirements set forth in the ADs can lead to significant legal consequences. While specific penalties are not detailed in the text, breaches of aviation safety regulations can result in both civil and criminal liabilities. Civil penalties may include fines and other monetary sanctions, whereas criminal penalties could involve imprisonment, depending on the severity of the breach. The regulatory framework also allows for the disallowance of ADs, ensuring that these instruments remain within the bounds of legislative intent and public interest. By adhering to these obligations and complying with the ADs, parties and entities can avoid the severe repercussions associated with non-compliance.
