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/SC7/6 affecting all Short Brothers & Harland SC7 (Skyvan) series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/SC7/6. The cancellation will become effective on 2 July 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, Airframe and Structures, 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 ensure the safety and efficiency of civil aviation in Australia, addressing the need for a robust regulatory framework that aligns with international standards. The Act empowers the Governor-General to create regulations aimed at enhancing air navigation safety, with the Civil Aviation Safety Regulations 1998 further detailing specific requirements, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs, which are legislative instruments, serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft types, as mandated by Annex 8 to the Convention on International Civil Aviation. The Act enables CASA to issue ADs in response to airworthiness concerns, ensuring that Australian aviation standards are met and maintained. The cancellation of a particular AD, such as AD/SC7/6 for Short Brothers & Harland SC7 (Skyvan) series aeroplanes, reflects the dynamic nature of airworthiness regulations, responding to evolving safety considerations and obligations under international conventions.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby ensuring the safety of air navigation. These directives, as disallowable instruments, are legislative in nature and are crucial for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 of the Convention on International Civil Aviation. The State of Design holds primary responsibility for the airworthiness of an aircraft type and must provide necessary information to the States of Registry, which include Australia. CASA, acting as Australia’s national airworthiness authority, is required to assess any ADs issued by States of Design and, if deemed necessary, issue corresponding Australian ADs to enforce the required safety measures. The recent cancellation of Australian AD/SC7/6 for the Short Brothers & Harland SC7 (Skyvan) series aeroplanes reflects Australia’s commitment to international obligations, and as the unsafe condition addressed by the AD no longer exists, no replacement directive is necessary.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further clarifies that the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework underscores the importance of maintaining aircraft safety standards and ensuring that the aviation industry adheres to these safety measures.
The obligations imposed by these provisions are significant. The State of Design, which is the country where the aircraft was designed, holds the primary responsibility for the continuing airworthiness of the aircraft type. This means they must provide any necessary information to ensure the aircraft's airworthiness to the States of Registry, which are the countries where the aircraft are registered. CASA, as Australia's national airworthiness authority, is obligated to assess the information provided by the State of Design and, if necessary, issue an Australian AD to mandate the required safety measures. This dual responsibility ensures that all stakeholders are aligned in their efforts to maintain safe air travel.
Non-compliance with ADs can lead to serious consequences. While specific offences and penalties are not detailed within the excerpt, it is understood that breaching these regulations could lead to civil or criminal penalties. The severity of these penalties would depend on the nature and extent of the non-compliance. The legislative nature of ADs, as outlined in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, reinforces the seriousness with which these directives are treated under Australian law.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for ensuring the safety of air navigation. They mandate specific responsibilities for the State of Design and the State of Registry, and empower CASA to issue and enforce ADs. The obligations placed on these entities are critical to maintaining the high safety standards required in the aviation industry. While the exact penalties for non-compliance are not specified, the legislative status of ADs implies that violations could result in significant legal consequences.
