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 EASA has issued AD 2008-0217 affecting Airbus Dornier 228 series aircraft. Germany is the State of Design for these aircraft. CASA has assessed this AD and has issued Australian AD/DO 228/15, which will become effective on 24 December 2008.
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 acting Manager, Airframes and Structures, in the Airworthiness Engineering Group, 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 legal framework for the regulation of civil aviation in Australia, addressing gaps in the oversight and safety standards for air navigation. This Act empowers the Governor-General to create regulations that prioritise the safety of air navigation, delegating authority to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for aircraft and aeronautical products, as stipulated in the Civil Aviation Safety Regulations 1998. In alignment with international obligations under Annex 8 to the Convention on International Civil Aviation, the Act mandates that Australia’s national airworthiness authority, CASA, must issue ADs to ensure the continuing airworthiness of aircraft registered in Australia, responding to directives issued by the State of Design. This legislative approach ensures compliance with international standards and fosters a robust safety framework for civil aviation in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments subject to disallowance and must comply with the Legislative Instruments Act 2003. The ADs are issued in response to international obligations under Annex 8 of the Convention on International Civil Aviation, which mandates the State of Design to provide information for the continuing airworthiness of aircraft types. The State of Registry, in this case CASA, must then assess and, if necessary, issue an Australian AD to ensure compliance with the airworthiness requirements. For instance, following an AD issued by the European Aviation Safety Agency (EASA) affecting the Airbus Dornier 228 series aircraft, CASA assessed the directive and issued AD/DO 228/15. This Australian AD, which will take effect on 24 December 2008, aligns with Australia's international commitments and the AD issued by Germany, the State of Design. Given that these directives are in response to international obligations and do not require public consultation, no Regulatory Impact Statement was deemed necessary by the Office of Regulatory Review. The AD was issued by the acting Manager, Airframes and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Safety Regulations 1998 (Regulation 39.001) empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This process is mandated by section 98 of the Civil Aviation Act 1988, allowing the Governor-General to establish regulations for air navigation safety. The ADs are a legislative instrument under the Legislative Instruments Act 2003 and serve as a common form of continuing airworthiness information, issued by most ICAO Contracting States, as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on the parties and entities governed by the Act are multifaceted. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to appropriate States of Registry to ensure the aircraft’s continuing airworthiness. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. CASA, as Australia’s national airworthiness authority, is required to assess any ADs issued by the State of Design and, if necessary, issue an Australian AD to mandate the requirements for aircraft on the Australian Register.
Breaches of airworthiness directives can lead to significant consequences. Under the Civil Aviation Act 1988, failure to comply with an AD can result in civil or criminal penalties. Civil penalties may include fines, and in some cases, criminal penalties may apply, leading to imprisonment. The severity of the penalty depends on the nature and extent of the breach, with maximum penalties outlined in the relevant sections of the Act. For example, under section 84A, the maximum penalty for failure to comply with an AD can be substantial, reflecting the critical importance of air safety and the potential risks associated with non-compliance.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for ensuring the safety of air navigation through the issuance and enforcement of airworthiness directives. These regulations impose clear obligations on the States of Design and Registry, as well as on CASA, to maintain the airworthiness of aircraft. Failure to adhere to these directives can result in serious civil and criminal penalties, underscoring the importance of compliance with aviation safety regulations.
