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 issued AD 2007-26-12, affecting Robinson R44 model helicopters, in 2007. The USA is the State of Design for this type. As a result of a request from industry, CASA has amended the equivalent Australian AD to allow the use of an FAA approved alternate means of compliance. The amended AD, AD/R44/22 Amendment 3, will become effective on 31 July 2008. 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, was introduced to establish a comprehensive legal framework for civil aviation in Australia, ensuring the safety, efficiency, and orderly development of the aviation industry. One of the key components of this framework is the regulation of airworthiness through the issuance of airworthiness directives (ADs). These directives are made under the authority granted by section 98 of the Act and are intended to maintain the airworthiness of aircraft, thereby protecting the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail the process by which ADs are issued, ensuring that they align with international standards and obligations under the Convention on International Civil Aviation. The policy objective is to mandate the continuing airworthiness of aircraft through effective regulatory measures, which includes the issuance of ADs in response to identified safety issues or in alignment with directives from the aircraft's State of Design.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), Australia's national airworthiness authority. Under the Civil Aviation Safety Regulations, CASA is authorised to issue ADs for specific types of aircraft or aeronautical products to ensure compliance with airworthiness standards. These ADs, which are legislative instruments, are necessary to maintain the continuing airworthiness of aircraft registered in Australia, aligning with international obligations under Annex 8 to the Convention on International Civil Aviation. The ADs are issued in response to directives from the State of Design, such as the FAA's AD 2007-26-12 for Robinson R44 model helicopters, and mandate specific compliance measures. While ADs do not require public consultation or a Regulatory Impact Statement, they are crucial for ensuring the safety of air navigation within Australia, impacting all entities involved in the operation and maintenance of affected aircraft types.
Key Provisions
The Civil Aviation Safety Regulations 1998 under section 39.001 permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments that mandate certain requirements to ensure the continuing airworthiness of aircraft, in accordance with Annex 8 of the Convention on International Civil Aviation. When an AD is issued by the State of Design, such as the United States Federal Aviation Administration (FAA) for the Robinson R44 model helicopters, CASA must evaluate the information and, if necessary, issue an Australian AD. Such was the case with AD 2007-26-12, which was amended to include an alternate means of compliance approved by the FAA.
These airworthiness directives impose obligations on the State of Registry to ensure the continuing airworthiness of aircraft registered within its jurisdiction. This involves adhering to the requirements set out in the ADs issued by the State of Design and any corresponding Australian ADs. The State of Design, such as the USA for the Robinson R44 model helicopters, is responsible for providing necessary information to ensure the airworthiness of the aircraft type. The State of Registry, in this case Australia, must assess this information and implement any necessary actions to maintain the airworthiness of the aircraft on its register.
Breaches of the requirements set out in ADs can result in various consequences. While the specific offences and penalties are not detailed in the provided text, it is clear that non-compliance with airworthiness directives can lead to safety issues and potential legal repercussions. CASA, as the national airworthiness authority, enforces these regulations to ensure compliance and uphold safety standards in Australian civil aviation. The authority to issue ADs and the obligation to comply with them are fundamental to maintaining the safety of air navigation in Australia.
The issuance of ADs such as AD/R44/22 Amendment 3 is a direct response to international obligations under the Convention on International Civil Aviation and the specific requirements of the State of Design. In this case, the amendment was made to incorporate an FAA-approved alternate means of compliance, reflecting the collaborative nature of international aviation safety standards. This process underscores the importance of international cooperation in maintaining global aviation safety. CASA's role in assessing and implementing these ADs is critical to ensuring that aircraft on the Australian Register meet the necessary safety standards.
In summary, the Civil Aviation Safety Regulations 1998 empower CASA to issue ADs to ensure the continuing airworthiness of aircraft. These directives are essential for compliance with international aviation standards and obligations. The responsibilities of both the State of Design and the State of Registry are pivotal in maintaining airworthiness. While the specific legal consequences of non-compliance are not detailed, the emphasis on safety and adherence to ADs highlights the importance of these regulations in the aviation industry.
