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/50 affecting aircraft batteries. CASA has assessed this AD and as a result has cancelled Australian AD/ELECT/50. The cancellation will become effective on 11 February 2008. 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 Acting 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, enacted to regulate the safety and efficiency of civil aviation in Australia, allows the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. This legislative framework is supplemented by the Civil Aviation Safety Regulations 1998, which among other things, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. These ADs, as specified under regulation 39.001(5) of the Civil Aviation Safety Regulations 1998, are considered disallowable instruments under the Acts Interpretation Act 1901, and thus constitute legislative instruments as per section 6 of the Legislative Instruments Act 2003. The ADs are a critical mechanism for ensuring the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as the national airworthiness authority, assesses the information provided by the State of Design and issues Australian ADs to mandate necessary requirements, ensuring compliance with international standards.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legislative framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for particular kinds of aircraft or aeronautical products. These ADs are legislative instruments that must adhere to the requirements set out in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The scope of the ADs extends to ensuring the continuing airworthiness of aircraft registered in Australia, aligning with the international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design, typically the manufacturer, has the primary responsibility for the airworthiness of an aircraft type, while the State of Registry, in this case CASA, must enforce these standards domestically. The issuance and cancellation of ADs, such as AD/ELECT/50 for aircraft batteries, are governed by CASA's assessment of safety information provided by the State of Design and the international obligations under the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Act 1988 (section 98) allows the Governor-General to make regulations for air navigation safety. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulation also establishes that an AD is a disallowable instrument under the Acts Interpretation Act 1901 (section 46A), and consequently, an AD is considered a legislative instrument according to the Legislative Instruments Act 2003 (section 6). These directives are essential for maintaining the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the overall responsibility for the airworthiness of an aircraft type and mandates it to provide necessary information to States of Registry.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 include ensuring that the State of Design, typically the manufacturer of the aircraft, provides necessary information to maintain the continuing airworthiness of an aircraft type. The State of Registry, in this case, CASA, has the responsibility to assess this information and, if necessary, issue an Australian AD to enforce the requirements set by the State of Design. This ensures that all aircraft registered in Australia meet the necessary safety standards. Additionally, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of the aircraft.
Failure to comply with airworthiness directives can lead to severe consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in civil penalties. The specific penalties can include fines, but the exact amount is not specified in the text. Additionally, CASA can take enforcement actions against the aircraft operator or owner, including grounding the aircraft if it is deemed unsafe to fly. In criminal cases, violations may lead to prosecution and potential imprisonment, although the exact penalties for criminal offences are not detailed in the provided text.
In summary, the key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for ensuring the safety and airworthiness of aircraft through the issuance of airworthiness directives. The obligations on the State of Design and State of Registry are to provide and implement necessary safety measures. The consequences for non-compliance can include civil penalties, aircraft grounding, and potential criminal prosecution, although the specific penalties are not exhaustively detailed in the provided text.
