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 Civil Aviation Safety Authority or its predecessors issued AD/ELECT/4 affecting Magnetos BTH AG4, SG4 and MC1 types with screened contact breaker covers. CASA has assessed this AD and as a result has cancelled Australian AD/ELECT/4. The cancellation will become effective on 12 February 2009. No replacement AD is required, as the unsafe condition no longer exists.
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, Systems and New Technologies, 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 legislative framework for the safety and efficiency of civil aviation in Australia. It grants authority to the Governor-General to make regulations for air navigation safety, including the issuance of airworthiness directives (ADs) to ensure aircraft and aeronautical products meet safety standards. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue ADs for specific kinds of aircraft or aeronautical products. The Civil Aviation Act 1988 aims to ensure that the continuing airworthiness of aircraft is maintained in accordance with international standards set by the International Civil Aviation Organization (ICAO). The State of Design has the responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the individual aircraft. CASA must assess ADs issued by the State of Design and, if necessary, issue Australian ADs to mandate the requirements. The AD/ELECT/4 cancellation exemplifies Australia's commitment to international civil aviation obligations and safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) within Australia. Under these regulations, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific kinds of aircraft or aeronautical products, thereby ensuring adherence to safety standards. These directives are legislative instruments that hold the force of law, mandated to uphold the safety of air navigation as outlined in section 98 of the Act. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to the State of Registry, which in Australia is represented by CASA. Consequently, CASA is obligated to assess the information provided by the State of Design and, if deemed necessary, issue an Australian AD. The scope of these regulations extends to all aircraft registered in Australia, ensuring that they meet the required safety standards. Notably, these directives do not require consultation with the public or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to enact regulations that serve the interests of air navigation safety. The Civil Aviation Safety Regulations 1998, through regulation 39.001, further specify that the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives, as outlined in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and the accompanying regulations require CASA to rigorously assess any ADs issued by the State of Design and to determine if an Australian AD should be issued to mandate these requirements. The State of Registry, which in this case is Australia, must ensure the continuing airworthiness of all aircraft registered within its borders, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. This includes the duty to develop or adopt necessary requirements to maintain the airworthiness of aircraft, and to act on ADs issued by the State of Design. CASA’s role is to translate these international standards into practical mandates for the Australian aviation sector.
In terms of legal consequences, breaches of airworthiness directives could lead to significant civil or criminal penalties. Under the Civil Aviation Act 1988, non-compliance with ADs could result in fines and imprisonment, as the regulations are designed to ensure the highest safety standards are met. Specifically, under the Civil Aviation Regulations 1988, penalties may include fines of up to $22,222 for individuals and $111,111 for corporations for each flight conducted in non-compliance with an AD. Furthermore, CASA has the authority to impose additional administrative actions, such as grounding of aircraft or suspension of air operator certificates, to enforce compliance.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for the issuance and enforcement of airworthiness directives to ensure the safety of air navigation. CASA is responsible for issuing and cancelling ADs based on assessments of international and domestic safety requirements. Failure to comply with these directives can result in severe penalties, underscoring the critical importance of adhering to the mandated safety protocols.
