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 United States FAA has issued AD 2007-23-16 affecting Cessna 525B model aircraft. The United States is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/CESSNA 525/6, which will become effective on 19 December 2007.
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, 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 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations for the purposes of the Act, specifically addressing the safety of air navigation. Under the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs serve as legislative instruments under the Acts Interpretation Act 1901 and are crucial for maintaining the continuing airworthiness of aircraft types, aligning with international standards set by the Convention on International Civil Aviation. The Australian AD/CESSNA 525/6 issued by CASA in response to an AD from the United States Federal Aviation Administration exemplifies the application of these regulations to ensure compliance with international obligations and domestic safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the scope and application of airworthiness directives (ADs) within Australia. Under these legislative frameworks, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs concerning specific types of aircraft or aeronautical products, as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. This regulatory power is exercised to ensure the safety of air navigation and to comply with international obligations, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. The Act applies to entities such as aircraft operators, manufacturers, and aviation authorities, ensuring adherence to safety standards and compliance with airworthiness directives. The jurisdiction of these regulations extends nationally, with CASA acting as the national airworthiness authority responsible for issuing ADs based on assessments of international directives. While ADs are legislative instruments, they do not require public consultation or a Regulatory Impact Statement, given their focus on international safety standards and the urgency of compliance.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for ensuring the safety of air navigation in Australia. Section 98 of the Act empowers the Governor-General to make regulations, while regulation 39.001 of the Civil Aviation Safety Regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs serve as a crucial means of maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. This convention designates the State of Design as having overall responsibility for the continuing airworthiness of an aircraft type, with the State of Registry required to adopt and enforce the necessary measures to ensure this airworthiness.
Under these regulations, CASA must act on ADs issued by the State of Design, such as the United States Federal Aviation Administration (FAA), by assessing and, if necessary, issuing corresponding Australian ADs. For example, the FAA issued AD 2007-23-16 for the Cessna 525B model aircraft, leading CASA to issue Australian AD/CESSNA 525/6, which became effective on 19 December 2007. Because these ADs are issued in compliance with international obligations and in response to directives from the relevant State of Design, they do not require public consultation or a Regulatory Impact Statement. The issuance of these ADs is a legislative instrument, as specified by section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations extend to ensuring that both the State of Design and the State of Registry adhere to the continuing airworthiness requirements. The State of Design must provide necessary information to the State of Registry, which in turn must implement the requirements to maintain the airworthiness of the aircraft. CASA, as Australia’s national airworthiness authority, plays a pivotal role in this process by assessing foreign ADs and issuing corresponding Australian ADs where necessary. These ADs carry legal weight, and their enforcement is critical to maintaining the safety standards required by the Civil Aviation Act and the Civil Aviation Safety Regulations.
Failure to comply with these ADs can result in serious consequences. The regulations do not explicitly outline specific offences, penalties, or civil/criminal consequences for non-compliance within the text provided. However, it is understood that non-compliance with ADs can lead to significant legal repercussions, including potential enforcement actions by CASA. These actions could range from fines to the grounding of non-compliant aircraft, depending on the severity of the breach. The overarching goal of these regulations is to ensure that all stakeholders adhere to the highest standards of airworthiness, thereby safeguarding the safety of air navigation.
