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 USA FAA issued AD 2005-26-10, affecting Lycoming aircraft engines, in 2005. USA is the State of Design for Lycoming engines. As a result of a request from the industry, CASA has amended the equivalent Australian AD to amendment 1. The amended AD, AD/LYC/113 Amendment 1, will become effective on 13 April 2006. This AD cancels and replaces the previous issue.
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, establishes the legal framework for civil aviation in Australia, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations necessary for the safety of air navigation, including the issuance of airworthiness directives (ADs) as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. The policy objective of this legislation is to ensure the continuing airworthiness of aircraft and aeronautical products, aligning with Australia's obligations under the Convention on International Civil Aviation, particularly those set out in Annex 8. The Civil Aviation Safety Authority (CASA) acts as the national airworthiness authority, responsible for issuing ADs that mandate compliance with international standards when required. For example, in response to the USA Federal Aviation Administration's AD 2005-26-10 concerning Lycoming aircraft engines, CASA issued an amended Australian AD to ensure continued safety and regulatory compliance within Australia's aviation sector.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, mandates the issuance of airworthiness directives (ADs) under regulation 39.001, overseen by the Civil Aviation Safety Authority (CASA). These directives apply to the types of aircraft or aeronautical products specified within the regulations, ensuring compliance with international standards for airworthiness as outlined in Annex 8 to the Convention on International Civil Aviation. The ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901. The scope of these regulations extends to the States of Design and Registry, requiring the State of Design to provide necessary information to ensure continuing airworthiness, while the State of Registry must implement the ADs to maintain the airworthiness of individual aircraft registered within its jurisdiction. The Civil Aviation Safety Regulations 1998 do not specify exclusions, exemptions, or thresholds, but they do permit the issuance of ADs in response to international directives, thereby enforcing compliance with international civil aviation standards.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for ensuring the safety of air navigation in Australia. Section 98 of the Act allows the Governor-General to make regulations for air navigation safety, and regulation 39.001 specifically authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and must comply with the Legislative Instruments Act 2003. Annex 8 of the Convention on International Civil Aviation outlines the responsibilities of the State of Design in ensuring the continuing airworthiness of an aircraft type and mandates the provision of necessary information to States of Registry.
Under the Civil Aviation Safety Regulations 1998, CASA, as Australia’s national airworthiness authority, has the obligation to assess any ADs issued by the State of Design and, if deemed appropriate, issue corresponding Australian ADs. This ensures that the requirements set forth by the State of Design are implemented in Australia. For example, when the USA Federal Aviation Administration (FAA) issued AD 2005-26-10 in 2005 concerning Lycoming aircraft engines, CASA amended the equivalent Australian AD to AD/LYC/113 Amendment 1, effective from 13 April 2006. This amendment cancels and replaces the previous AD, demonstrating the seamless integration of international safety directives into Australia’s regulatory framework.
Entities governed by these regulations, such as aircraft operators and manufacturers, must comply with ADs by adhering to the specified safety requirements. These directives may include mandatory inspections, repairs, modifications, or operational limitations to ensure the continuing airworthiness of the aircraft. Failure to comply with ADs can result in severe consequences, as non-compliance with safety regulations can lead to significant risks to aviation safety. CASA has the authority to take enforcement actions against non-compliant entities, which can include grounding of aircraft, fines, and other penalties. The maximum penalties for breaches of these regulations are determined by the specific circumstances and the severity of the non-compliance, but can include substantial financial penalties and potential criminal charges for serious breaches.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for the issuance and enforcement of airworthiness directives to ensure the safety of air navigation. CASA plays a pivotal role in assessing and implementing these directives, and entities such as aircraft operators and manufacturers must comply to maintain safety standards. Non-compliance can result in serious civil and criminal consequences, including fines and potential imprisonment.
