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 2008-13-28 affecting Hartzell propellers. The United States is the State of Design for these propellers. CASA has assessed this AD and has issued Australian AD/PHZL/91, which will become effective on 28 August 2008.
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 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 establish a legislative framework governing civil aviation safety and regulation within Australia, aiming to ensure the safe and efficient use of the nation’s airspace. Complementing the Act, the Civil Aviation Safety Regulations 1998 provide detailed provisions concerning airworthiness and operational standards. The Act empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft and aeronautical products, thereby ensuring public safety and compliance with international standards set by the International Civil Aviation Organization (ICAO). The issuance of ADs is a crucial mechanism through which CASA fulfills its obligations under the Convention on International Civil Aviation and responds to safety concerns raised by the aircraft's State of Design. This legislative instrument was developed by CASA, under the authority granted by the Act, and is issued without public consultation as it aligns with international obligations and pre-existing safety protocols.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, as stipulated in regulation 39.001. These ADs are legislative instruments and are subject to disallowance as per section 46A of the Acts Interpretation Act 1901. In accordance with Annex 8 of the Convention on International Civil Aviation, the State of Design bears the primary responsibility for the continuing airworthiness of an aircraft type, necessitating the provision of necessary information to ensure airworthiness to the relevant States of Registry. CASA, as Australia's national airworthiness authority, must evaluate any ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs to enforce the requirements. This mechanism ensures that Australian aviation adheres to international safety standards and practices.
Key Provisions
The main operative sections of this legislation revolve around the issuance and enforcement of airworthiness directives (ADs) under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This regulation specifies that ADs are disallowable instruments, as per section 46A of the Acts Interpretation Act 1901, and are classified as legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by this Act on CASA and other entities are primarily centred on ensuring the continuing airworthiness of aircraft. CASA, as Australia’s national airworthiness authority, is responsible for assessing ADs issued by the State of Design, such as the United States in the case of Hartzell propellers, and subsequently issuing corresponding Australian ADs if necessary. These ADs are intended to mandate the requirements for maintaining the airworthiness of aircraft registered in Australia. The State of Registry of an individual aircraft is also obligated to develop or adopt requirements that ensure the continuing airworthiness of those aircraft, in accordance with Annex 8 of the Convention on International Civil Aviation.
In terms of breaches and penalties, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences or penalties related to non-compliance with ADs. However, failure to adhere to ADs can lead to significant civil and criminal consequences. For instance, operating an aircraft that does not comply with an AD could result in severe penalties, including fines and imprisonment, as the overarching goal is to maintain the safety of air navigation. Although the specific maximum penalties are not detailed within the text, the potential ramifications for non-compliance are substantial, reflecting the critical nature of airworthiness directives in ensuring aviation safety.
