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 2006-11-16 affecting Honeywell T53 series engines. The United States is the State of Design for this engine series. CASA has assessed this AD and has issued Australian AD/T53/22, which will become effective on 3 August 2006.
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 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 a legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. This legislation allows the Governor-General to make regulations for the purposes of the Act, and under section 98, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. This regulatory mechanism ensures that the continuing airworthiness of aircraft is maintained in accordance with international standards set by the International Civil Aviation Organization (ICAO). The policy objective is to enhance aviation safety by implementing consistent and effective airworthiness directives, which are critical for maintaining the safety standards of aircraft registered in Australia. The Civil Aviation Safety Regulations 1998, and specifically regulation 39.001, formalise the process by which CASA can mandate compliance with these directives, thereby aligning Australia's aviation safety practices with international obligations and ensuring a coordinated approach to aircraft safety across different jurisdictions.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure the safety of air navigation. These directives, which are legislative instruments, mandate actions to maintain or restore the airworthiness of aircraft, and they are crucial in fulfilling Australia’s obligations under international agreements such as Annex 8 to the Convention on International Civil Aviation. The State of Design, in this case, the United States, holds the primary responsibility for the continuing airworthiness of aircraft types and must provide necessary information to the States of Registry, such as Australia, to ensure compliance with safety standards. CASA, as Australia’s national airworthiness authority, is required to assess this information and issue corresponding ADs when necessary. For instance, CASA issued Australian AD/T53/22 in response to the United States FAA’s AD 2006-11-16, which pertains to the Honeywell T53 series engines. Given that these directives are issued due to international obligations and in response to directives from the relevant State of Design, there is no requirement for public consultation or the preparation of a Regulatory Impact Statement. This AD was made by the Manager, New Technologies and Systems, in CASA’s Manufacturing, Certification and New Technologies Office, in line with subsection 84A(2) of the Civil Aviation Act 1988.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998 (CASR) relevant to airworthiness directives (ADs) are sections 39.001 and 39.001(5). Section 39.001 permits the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are formal directives that aim to ensure the continuing airworthiness of aircraft by mandating specific maintenance, inspection, or repair actions. Section 39.001(5) states that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus they are legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed on parties and entities by these provisions are primarily on CASA. As Australia's national airworthiness authority, CASA is responsible for assessing airworthiness directives issued by the State of Design and determining whether to issue an Australian AD to mandate these requirements. This ensures that the continuing airworthiness of aircraft on the Australian Register is maintained in accordance with international standards. The State of Registry, which is the country where the aircraft is registered, also has obligations under Annex 8 of the Convention on International Civil Aviation to ensure the continuing airworthiness of aircraft.
There are no specific offences or penalties outlined in the Civil Aviation Safety Regulations 1998 for failing to comply with an airworthiness directive. However, non-compliance with ADs can lead to severe consequences, including potential grounding of aircraft, which can result in significant operational disruptions and financial loss for operators. The safety and regulatory frameworks in place ensure that compliance with ADs is mandatory, and failure to adhere to these can lead to enforcement actions by CASA.
Under the Civil Aviation Act 1988, CASA has the authority to enforce compliance with ADs through various means, including audits, inspections, and the imposition of fines or other penalties. The severity of these penalties can vary based on the nature and extent of non-compliance. For instance, serious breaches that lead to safety hazards may attract higher penalties. However, specific maximum penalties are not detailed in the provided text. It is important for operators and owners of affected aircraft to ensure that all mandated actions in ADs are promptly and thoroughly addressed to avoid any regulatory action or safety risks.
