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 2007-13-01 affecting Boeing 717-200 series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B717/22, which will become effective on 30 August 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia and to establish the Civil Aviation Safety Authority (CASA) as the national airworthiness authority. One of the key problems it addressed was the need for a comprehensive framework to ensure the safety and airworthiness of aircraft operating within Australian airspace, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Act empowers the Governor-General to make regulations for air navigation safety, delegating authority to CASA to issue airworthiness directives (ADs) under the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments designed to mandate specific requirements for aircraft types registered in Australia, ensuring compliance with international standards and maintaining the safety of air navigation. The ADs are issued pursuant to Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates the State of Design's responsibility for continuing airworthiness. CASA, as the State of Registry, is obligated to assess and, if necessary, implement Australian ADs in response to ADs issued by the State of Design, such as the United States Federal Aviation Administration (FAA). This process ensures that Australian-registered aircraft meet the necessary safety standards set forth by international and domestic regulations.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft and aeronautical products, ensuring adherence to safety standards. These directives are legally binding instruments aimed at maintaining or restoring airworthiness, and are subject to disallowance procedures under the Acts Interpretation Act 1901. Airworthiness directives are typically issued in response to safety concerns identified by the State of Design and must be assessed and, if necessary, adopted by the State of Registry, which in Australia is CASA. For instance, CASA issued AD/B717/22 in response to an AD from the United States Federal Aviation Administration concerning Boeing 717-200 series aircraft. The process for issuing such directives does not involve public consultation due to their alignment with international aviation safety standards under the Convention on International Civil Aviation. The issuance of these directives is carried out by authorised CASA personnel in accordance with the relevant sections of the Civil Aviation Act 1988.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 that pertain to the issuance of airworthiness directives (ADs) include section 98 of the Act, which empowers the Governor-General to make regulations for air navigation safety, and regulation 39.001 of the Regulations, which allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific aircraft or aeronautical products. These ADs serve as legislative instruments under subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003. This regulatory framework ensures that Australia adheres to international standards set by the Convention on International Civil Aviation, particularly through Annex 8, which mandates the State of Design to maintain the continuing airworthiness of aircraft types and share necessary information with States of Registry.
The obligations imposed on parties governed by these provisions include the requirement for the State of Design to provide information on airworthiness to relevant States of Registry. For Australia, CASA, as the national airworthiness authority, must evaluate any ADs issued by the State of Design and determine whether to issue an Australian AD. This process ensures that Australian aircraft meet international safety standards and are maintained in a safe condition. CASA’s role is critical in assessing foreign ADs and adapting them to the Australian context, thereby maintaining the safety and reliability of the Australian civil aviation fleet.
Failure to comply with ADs can lead to significant legal consequences. Under the Civil Aviation Act 1988 and associated regulations, non-compliance with an AD can result in both civil and criminal penalties. For example, operating an aircraft in violation of an AD can lead to fines or imprisonment, reflecting the serious nature of ensuring air safety. The maximum penalties can vary, but they underscore the importance of adhering to airworthiness directives to maintain the highest safety standards in aviation. CASA has the authority to enforce these regulations and can take action against non-compliant aircraft or operators, thereby reinforcing the importance of compliance with ADs.
