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/BEECH 55/16 affecting Beechcraft D55 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 55/16. The cancellation will become effective on 5 June 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 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 by the Commonwealth Parliament, serves to provide a legislative framework for the regulation of civil aviation in Australia, with a key focus on safety. This Act empowers the Governor-General to make regulations in the interest of air navigation safety. One such regulation, specified in the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are legislative instruments that are issued to maintain the continuing airworthiness of aircraft in accordance with international standards set out in the Convention on International Civil Aviation. The ADs ensure that any unsafe conditions identified in aircraft types are addressed promptly, aligning with Australia's obligations under international conventions. The Civil Aviation Safety Regulations also outline the procedures for the issuance, assessment, and cancellation of these directives, as demonstrated by the recent cancellation of AD/BEECH 55/16 for the Beechcraft D55 model aircraft.
Scope and Application
The Civil Aviation Safety Regulations 1998, as an instrument of the Civil Aviation Act 1988, applies to all entities and individuals involved in the civil aviation industry in Australia, specifically those concerned with the safety and airworthiness of aircraft and aeronautical products. This encompasses aircraft operators, maintenance organisations, manufacturers, and other relevant stakeholders within the aviation sector. The regulations have a national reach, enforcing standards and requirements to ensure the safety of air navigation across Australia. Notably, the regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that can be enforced as legislative instruments, thus extending their application through subordinate instruments as necessary. These ADs are essential for maintaining the continuing airworthiness of aircraft, with CASA acting on behalf of the Australian government to issue and enforce such directives. The regulations also align with international obligations under the Convention on International Civil Aviation, ensuring that Australia's aviation safety practices are consistent with global standards.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) provide the legal framework for the issuance of airworthiness directives (ADs). Under these provisions, the Civil Aviation Safety Authority (CASA) is authorised to issue ADs for specific kinds of aircraft or aeronautical products to ensure the safety of air navigation. Section 39.001(5) of the Civil Aviation Safety Regulations 1998 further clarifies that an AD is a disallowable instrument, making it a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003. These directives are integral to maintaining the continuing airworthiness of aircraft, as stipulated by Annex 8 to the Convention on International Civil Aviation.
Under these regulations, the State of Design bears the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure the safety and compliance of aircraft with airworthiness standards. The State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must develop or adopt requirements to enforce these standards. When a State of Design issues an AD for an aircraft type on the Australian Register, CASA, as Australia’s national airworthiness authority, is required to assess the information and, if deemed appropriate, issue an Australian AD to enforce the requirements of the State of Design. This ensures that all aircraft operating in Australia meet the necessary safety standards.
The obligations imposed by these provisions include the responsibility of CASA to assess and, if necessary, issue Australian ADs in response to international directives. CASA must ensure that the ADs issued are in compliance with international safety standards and obligations under the Convention on International Civil Aviation. The State of Registry, in this case, Australia, must also ensure that all aircraft registered within its jurisdiction meet the airworthiness standards set forth in the ADs. The obligations extend to the manufacturers of the aircraft to provide necessary information and comply with the ADs issued to maintain the safety and airworthiness of their products.
In terms of consequences for non-compliance, breaching the requirements set forth in an AD can lead to significant penalties. Although specific penalties are not detailed in the text, non-compliance with airworthiness directives can generally result in civil penalties, including fines or revocation of airworthiness certificates. In more severe cases, criminal charges may be pursued, leading to imprisonment or substantial fines. The severity of the penalties reflects the critical importance of air safety and the potential risks associated with non-compliance with airworthiness directives.
