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 2008-15-05 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/340, which will become effective on 25 September 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes 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 by the Australian Parliament, governs civil aviation matters within Australia, including the regulation of airworthiness. This Act empowers the Governor-General to create regulations in the interest of air navigation safety. One such regulation, under regulation 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments subject to disallowance, as stipulated in the Legislative Instruments Act 2003. The policy objective behind these regulations is to ensure the continuing airworthiness of aircraft in line with international standards set forth in Annex 8 to the Convention on International Civil Aviation, which mandates the State of Design to provide necessary information for maintaining airworthiness. Consequently, CASA issues Australian ADs in response to ADs issued by the State of Design, such as the US Federal Aviation Administration's AD 2008-15-05 for Boeing B737 model aircraft, which CASA has evaluated and will implement as AD/B737/340 effective from 25 September 2008.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, provides the legislative framework within which airworthiness directives (ADs) are issued to ensure the safety of aircraft within Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations for the purposes of the Act, which includes ensuring the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for kinds of aircraft or aeronautical products. These ADs are legislative instruments that must be assessed and, if appropriate, adopted by CASA in response to directives issued by the aircraft's State of Design, ensuring compliance with international obligations under the Convention on International Civil Aviation. The ADs are specifically tailored to mandate the requirements for continuing airworthiness of aircraft registered in Australia, with no public consultation required as they are issued in response to international obligations and directives from the State of Design. This process ensures that the safety standards and regulatory requirements set by the international aviation community are consistently applied within the Australian jurisdiction.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to establish regulations for the Act's purposes, specifically to ensure the safety of air navigation. According to regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. The issuance of ADs is crucial for maintaining the airworthiness of aircraft, and these directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901. Consequently, as per section 6 of the Legislative Instruments Act 2003, ADs are classified as legislative instruments.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on the parties involved are significant. The State of Design, which is responsible for the aircraft type, must provide any necessary information to ensure the continuing airworthiness of the aircraft type to the appropriate States of Registry. In this context, the State of Registry must develop or adopt requirements to ensure the aircraft's continuing airworthiness. When the State of Design issues an AD, CASA must assess the information and, if deemed necessary, issue an Australian AD to enforce the State of Design's requirements. This process ensures that Australian-registered aircraft meet the required safety standards.
Under these regulations, any breach of the airworthiness requirements could lead to severe consequences. Failure to comply with an AD could result in the grounding of an aircraft, leading to significant operational disruptions and potential safety hazards. From a legal standpoint, the Civil Aviation Act 1988 provides CASA with the authority to take enforcement actions against entities that do not comply with ADs. While specific penalties for non-compliance are not detailed in the provided text, they could include fines, operational restrictions, or other regulatory measures designed to enforce compliance and ensure the safety of air navigation. The severity of these penalties is intended to compel adherence to the safety standards set forth by the ADs.
