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 2006-24-07 affecting McCauley propellers. The United States is the State of Design for these propellers. CASA has assessed this AD and has issued Australian AD/PMC/51 which will become effective on 7 June 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 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, enacted by the Commonwealth Parliament, was established to provide a legal framework for the regulation of civil aviation in Australia, with a primary focus on ensuring safety and efficiency in air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of this Act, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as per regulation 39.001. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, reflecting their regulatory nature and the importance of ensuring that they comply with international standards set by the International Civil Aviation Organization (ICAO). The policy objective is to mandate continuing airworthiness requirements for aircraft and aeronautical products, ensuring they meet safety standards, and to align with Australia’s obligations under international conventions, particularly the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. These ADs are legislative instruments and apply to aircraft and aeronautical products registered in Australia. CASA, as Australia's national airworthiness authority, must assess airworthiness information provided by the State of Design and issue Australian ADs when necessary. The process of issuing these directives is governed by Australia’s obligations under the Convention on International Civil Aviation and does not require public consultation or a Regulatory Impact Statement. This legislative mechanism ensures that Australian-registered aircraft meet international safety standards and are maintained in a continuing airworthy condition.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides a framework for the issuance of airworthiness directives (ADs). Specifically, section 98 of the Act authorises the Governor-General to make regulations in the interest of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This regulatory power is further delineated in subregulation 39.001(5), which identifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby classifying them as legislative instruments.
The obligations imposed by the Civil Aviation Act and the Civil Aviation Safety Regulations are significant for the entities they govern. The State of Design, as per Annex 8 of the Convention on International Civil Aviation, holds primary responsibility for the continuing airworthiness of an aircraft type, requiring it to furnish any necessary information to appropriate States of Registry. In Australia, CASA, as the national airworthiness authority, is tasked with assessing any ADs issued by the State of Design and, if deemed necessary, issuing an Australian AD to enforce the requirements. Similarly, the State of Registry must develop or adopt requisite measures to ensure the continuing airworthiness of aircraft within its jurisdiction.
Failure to comply with the ADs can lead to severe legal consequences. Although specific offences and penalties are not detailed in the provided text, general aviation law typically includes provisions for both civil and criminal penalties. These could range from fines to imprisonment, depending on the severity and intent of the breach. Furthermore, non-compliance could potentially lead to aircraft being grounded, affecting operational safety and leading to substantial financial and reputational damage for the entities involved.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for ensuring the safety and airworthiness of aircraft through the issuance of ADs. These regulations impose clear obligations on the States of Design and Registry, with CASA playing a pivotal role in enforcing these standards within Australia. While the specific penalties for non-compliance are not outlined in the provided text, the potential consequences underscore the importance of adhering to these regulatory requirements.
