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 2009-04-04 affecting Cessna 401 and 402 model aircraft. The USA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/CESSNA 400/118, which will become effective on
2 March 2009.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes & 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 for the regulation of civil aviation in Australia, particularly focusing on the safety of air navigation. The Act empowers the Governor-General to make regulations that are essential for the safety of air navigation. In line with this, the Civil Aviation Safety Regulations 1998 were formulated, which among other provisions, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This legislative framework is crucial for ensuring that aircraft meet continuing airworthiness standards, aligning with international obligations under the Convention on International Civil Aviation. The Civil Aviation Act 1988 thus addresses the need for a robust regulatory system to oversee the safety and airworthiness of aircraft operating in Australian airspace.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provides the legislative framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the purposes of the Act, which in this case includes the issuance of ADs through regulation 39.001. These directives are legislative instruments that fall under the purview of the Legislative Instruments Act 2003, and they serve to mandate the continuing airworthiness of specific types of aircraft or aeronautical products. The State of Registry, which in Australia's case is CASA, is responsible for ensuring that these requirements are implemented and enforced. Given the international obligations under the Convention on International Civil Aviation, specifically Annex 8, the State of Design, which for certain aircraft types includes the United States, is tasked with providing necessary information to maintain airworthiness, and Australia, as a State of Registry, must respond by issuing appropriate ADs. This regulatory mechanism ensures that aircraft registered in Australia meet international safety standards, and it underscores the collaborative nature of aviation safety oversight between nations.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to make regulations that promote the safety of air navigation, with the Civil Aviation Safety Regulations 1998 (regulation 39.001) providing the specific authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, are legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. The issuance of an AD by CASA is a critical mechanism in ensuring the continuing airworthiness of aircraft registered in Australia, particularly when mandated by the aircraft's State of Design under Annex 8 to the Convention on International Civil Aviation.
The obligations imposed on CASA and other parties by the Civil Aviation Safety Regulations 1998 include the requirement to assess ADs issued by the State of Design and, if deemed necessary, to issue corresponding Australian ADs. This process ensures that all aircraft registered in Australia meet the necessary safety standards. The State of Registry is also obliged to develop or adopt requirements that ensure the continuing airworthiness of aircraft within its jurisdiction. These obligations are integral to maintaining the high safety standards expected in the aviation industry and are in line with the international obligations under the Convention on International Civil Aviation.
Breach of the requirements outlined in the Civil Aviation Safety Regulations 1998, particularly failure to comply with ADs, can lead to significant consequences. While the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail specific penalties for non-compliance with ADs, breaches can result in severe civil and criminal consequences. Non-compliance may lead to the grounding of aircraft, which can have significant financial and operational repercussions for the operators. Additionally, in more serious cases, there can be criminal prosecution under the Civil Aviation Act 1988, which can result in fines and imprisonment. The exact penalties can vary depending on the severity and intent of the breach, but they are designed to ensure strict adherence to safety regulations.
