CIVIL AVIATION ACT 1988
CIVIL AVIATION 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. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
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 issued AD 94-03-07, affecting Boeing 767 aircraft, in 1994. The USA is the State of Design for this type. As a result of a request from industry, CASA has amended the equivalent Australian AD to update references to documentation specified in the AD. The amended AD, AD/B767/76 Amendment 1, will become effective on 17 February 2005. 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Parliament of Australia, was introduced to regulate the safety and efficiency of civil aviation within the country. This legislation provides the legislative framework for ensuring the safety of air navigation and the continuing airworthiness of aircraft, and it empowers the Civil Aviation Safety Authority (CASA) to issue regulations and directives necessary to achieve these objectives. One of the critical tools CASA employs is the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs mandate compliance with safety standards and address specific safety issues related to aircraft or aeronautical products. The policy objective of the Act is to safeguard the public by maintaining high safety standards in civil aviation, aligning with Australia’s international obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 applies to all aspects of civil aviation within Australia, regulating entities such as aircraft operators, aviation service providers, and aviation personnel, as well as governing the conduct and transactions related to civil aviation. The Act encompasses both national and international aviation activities to ensure compliance with safety standards and regulations. The Civil Aviation Safety Regulations 1998 further delineate the specific requirements and operational standards for airworthiness, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). ADs are binding instruments that mandate corrective actions or modifications for specific types of aircraft to ensure their continuing airworthiness. These regulations extend to all aircraft registered in Australia, aligning with international standards set by the International Civil Aviation Organization (ICAO). Notably, the Act and its subordinate regulations do not apply to military aircraft or operations primarily conducted for defence purposes. The issuance and amendment of ADs, such as the example provided for Boeing 767 aircraft, are executed by CASA under the authority granted by the Act, with the process adhering to international obligations and conventions, including the Convention on International Civil Aviation.
Key Provisions
The main operative sections of this legislation are section 98 of the Civil Aviation Act 1988, which empowers the Governor-General to make regulations in the interests of the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. This authority is exercised by CASA under the oversight of the State of Design, which has the overall responsibility for the continuing airworthiness of an aircraft type as per Annex 8 to the Convention on International Civil Aviation. CASA, as the national airworthiness authority, must assess information from the State of Design and, if necessary, issue an Australian AD to enforce the requirements of the State of Design.
The obligations imposed on the parties governed by this Act include the responsibility of the State of Design to provide necessary information to ensure the continuing airworthiness of a type to appropriate States of Registry. The State of Registry, in this case, CASA, must then develop or adopt requirements to ensure the continuing airworthiness of aircraft within their jurisdiction. For the Boeing 767 aircraft, this involves CASA amending the equivalent Australian AD when requested by industry and updating references to documentation specified in the AD. This process ensures that all parties involved adhere to the highest safety standards as mandated by international conventions and national regulations.
The issuance of airworthiness directives is critical in maintaining safety standards in aviation, and failure to comply with these directives can lead to significant consequences. Any breach of an AD may result in civil or criminal penalties, although the specifics of these penalties are not detailed in the provided text. However, the importance of compliance is underscored by the authority of CASA to issue ADs as a means of enforcing airworthiness requirements. The regulatory framework ensures that any non-compliance could lead to severe repercussions, including potential grounding of aircraft and legal action against the responsible parties.
The ADs, such as AD/B767/76 Amendment 1, are issued to ensure that all aircraft meet the required safety standards. The effectiveness of these measures is dependent on the adherence of all stakeholders, including aircraft manufacturers, operators, and regulatory bodies. The AD is issued without public consultation due to its basis in international obligations and in response to an AD raised by the relevant State of Design. This streamlined process ensures that safety measures are implemented promptly and effectively, without unnecessary delays. The AD has been crafted by the Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A(2) of the Act, ensuring that it is issued with the proper authority and oversight.
