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 US FAA has issued AD 2007-24-14 affecting Hartzell propellers. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/PHZL/90, which will become effective on 31 July 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 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 safety and efficiency in the industry. Under this Act, the Governor-General has the authority to create regulations that promote the safety of air navigation, which is further elaborated upon in the Civil Aviation Safety Regulations 1998. Specifically, regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products, thereby ensuring adherence to safety standards and continuing airworthiness. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. In line with international obligations under the Convention on International Civil Aviation, Australia’s national airworthiness authority, CASA, is mandated to assess and implement ADs issued by the State of Design, ensuring that Australian aircraft meet global safety standards.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that are applicable to specific kinds of aircraft or aeronautical products to ensure safety in air navigation. This Act applies to all entities and individuals involved in the operation, maintenance, and design of aircraft within Australia, encompassing various industries including commercial aviation, general aviation, and aeronautical manufacturing. The geographical scope of this legislation is national, with CASA acting as Australia's overarching airworthiness authority. Exclusions and exemptions from the application of ADs are generally not specified within the Act itself but are determined through subordinate instruments and specific regulatory provisions. The issuance of ADs is often mandated by international obligations under the Convention on International Civil Aviation, and in such cases, the ADs are formulated in response to directives from the relevant State of Design, such as the US Federal Aviation Administration (FAA) in the instance of Hartzell propellers. Consequently, while the Act provides a broad framework for AD issuance, the detailed application and enforcement are governed by the specific conditions and requirements set out in these subordinate instruments.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to enact regulations that align with the Act’s objectives and safety requirements for air navigation. Under this legislative framework, the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments as defined by section 6 of the Legislative Instruments Act 2003.
In accordance with Annex 8 to the Convention on International Civil Aviation, the State of Design holds overarching responsibility for the continuing airworthiness of an aircraft type, which includes providing necessary information to the appropriate States of Registry. This ensures the maintenance of airworthiness standards across international borders. The State of Registry, in turn, must implement or adopt the necessary requirements to ensure that individual aircraft remain airworthy. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA, as the national airworthiness authority, is required to review this information and, if deemed necessary, issue an Australian AD to enforce the requirements set by the State of Design.
The obligations placed on parties under this Act include the State of Design’s duty to provide critical information regarding airworthiness and the State of Registry’s responsibility to establish or adopt the requisite standards for maintaining airworthiness. CASA must evaluate any ADs issued by foreign authorities and, if appropriate, promulgate corresponding Australian ADs to ensure compliance with international standards. This collaborative approach underscores the importance of maintaining consistent air safety protocols across different jurisdictions.
Failure to comply with the requirements outlined in an AD can result in severe consequences. Section 94 of the Civil Aviation Act 1988 provides that an AD is enforceable by CASA, which may impose fines or other penalties for non-compliance. The maximum penalties for contravening an AD can include substantial fines, imprisonment, or both, depending on the severity of the offence and the discretion of the court. Additionally, non-compliance can result in grounding of the aircraft, suspension of airworthiness certificates, or other regulatory actions that could impact the safety and operational status of the aircraft.
