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 2006-0316R1, affecting BRP-Rotax GmbH & Co. Kg engines. Germany is the State of Design for these engines. CASA has amended the equivalent Australian AD to AD/ROTAX/22 Amendment 1. The amended AD, AD/ROTAX/22 Amendment 1 will become effective on 3 July 2008. This AD cancels and replaces the previous issue.
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, Systems and New Technologies in the Airworthiness Engineering Branch, 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 legislative framework for the regulation of civil aviation in Australia, primarily to ensure the safety of air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were also established to further delineate the safety requirements for aircraft and aeronautical products, including the issuance of airworthiness directives (ADs). These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, ensuring the continuing airworthiness of aircraft registered in Australia. The ADs are critical tools in enforcing international safety standards as outlined in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design holds responsibility for the continuing airworthiness of aircraft types and must provide necessary information to States of Registry. CASA, acting as Australia’s national airworthiness authority, is tasked with assessing this information and issuing appropriate ADs to comply with international obligations and maintain safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together facilitate the regulation of airworthiness directives (ADs) in Australia, ensuring that aircraft and aeronautical products meet continuing safety standards. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products, with these directives being considered disallowable instruments under the Acts Interpretation Act 1901. These regulations apply to all entities and individuals involved in the operation, maintenance, and registration of aircraft within Australia, and extend to the broader aviation industry by ensuring adherence to international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The ADs are a reflection of Australia’s commitment to international obligations and cooperation in aviation safety. The issuance of ADs, such as the Australian AD/ROTAX/22 Amendment 1, is directly linked to actions taken by the State of Design and does not involve public consultation as it is a response to international regulatory requirements.
Key Provisions
The Civil Aviation Act 1988, through section 98, grants the Governor-General the authority to make regulations that are in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are legislative instruments as per section 6 of the Legislative Instruments Act 2003 and can be disallowed under section 46A of the Acts Interpretation Act 1901. This legal framework ensures that ADs are consistent with international standards, particularly those set forth in Annex 8 to the Convention on International Civil Aviation, which outlines the responsibilities of the State of Design and the State of Registry in maintaining the continuing airworthiness of aircraft.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to monitor and respond to ADs issued by the State of Design, which is the country responsible for the design of the aircraft or product in question. In this context, Germany is the State of Design for BRP-Rotax GmbH & Co. Kg engines, and CASA, as Australia’s national airworthiness authority, must review and, if necessary, issue an Australian AD to implement the requirements of the German AD. This process ensures that Australian-registered aircraft meet international safety standards. CASA must also ensure that these ADs are communicated effectively to the relevant stakeholders, including aircraft operators and maintenance organisations, to maintain the continuing airworthiness of aircraft.
Failure to comply with the requirements set out in an AD can lead to significant consequences. Under the Civil Aviation Act 1988, non-compliance can result in civil penalties, including fines of up to $16,500 for individuals and significantly higher penalties for corporations. Additionally, CASA can take enforcement actions such as grounding non-compliant aircraft, which can severely impact the operations of airlines and other aviation businesses. In severe cases, criminal charges can be pursued, leading to substantial fines and imprisonment for individuals responsible for the non-compliance. These stringent measures underscore the importance of adhering to airworthiness directives to ensure the safety of air navigation.
