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 2008-11-03 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/333, 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, 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 to address the need for comprehensive regulation of civil aviation safety and operations in Australia, empowers the Governor-General to establish regulations aimed at ensuring the safety of air navigation. This Act provides the legal framework within which the Civil Aviation Safety Regulations 1998 operate, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). The policy objective underlying these regulations is to maintain and enhance the safety standards of air navigation and aircraft operations, in alignment with international conventions such as the Convention on International Civil Aviation. These directives are crucial for ensuring that aircraft types registered in Australia meet continuing airworthiness standards, as mandated by the State of Design and enforced by CASA, Australia's national airworthiness authority.
Scope and Application
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 provide the legislative framework for ensuring the safety of air navigation in Australia. Under section 98 of the Civil Aviation Act, the Governor-General has the authority to make regulations for the purposes of the Act, specifically focusing on the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby establishing and enforcing safety standards. These ADs are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. They serve as a mechanism to ensure that aircraft maintain their airworthiness in accordance with international standards set by the International Civil Aviation Organization (ICAO). The State of Design, which is responsible for the design of the aircraft type, must provide necessary information to the State of Registry, where CASA as Australia’s national airworthiness authority, assesses and, if necessary, issues corresponding Australian ADs. These directives apply to all relevant aircraft registered in Australia and are designed to harmonise with international safety requirements.
Key Provisions
The key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for ensuring the safety of air navigation, particularly in relation to airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations that are in the interests of air navigation safety. Specifically, 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. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, as they are disallowable instruments as per section 46A of the Acts Interpretation Act 1901.
The obligations imposed by the Act and Regulations are significant for both the State of Design and the State of Registry. The State of Design has the overarching responsibility for the continuing airworthiness of a particular aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. This responsibility includes providing necessary information to ensure the aircraft's continuing airworthiness to the appropriate States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the airworthiness of individual aircraft registered within its jurisdiction. In the context of Australia, CASA, as the national airworthiness authority, must evaluate ADs issued by the State of Design and, where necessary, issue corresponding Australian ADs to enforce the required safety measures.
The regulations also outline the consequences of non-compliance with ADs. The Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 do not specify particular offences or penalties for breaching ADs within their text, but non-compliance could result in significant civil or criminal penalties under broader aviation safety laws. The failure to comply with an AD could lead to serious safety incidents, and CASA has the authority to take enforcement actions, which might include grounding aircraft, imposing fines, or taking other regulatory measures against the operators or manufacturers who fail to comply with ADs.
Given the international nature of aviation, the Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 also reflect Australia's obligations under the Convention on International Civil Aviation. This includes the requirement to align with ADs issued by other Contracting States, such as the United States Federal Aviation Administration (FAA), as seen with AD 2008-11-03 for Boeing B737 model aircraft. CASA's assessment and issuance of Australian AD/B737/333, effective from 31 July 2008, underscore the need to harmonise international safety standards with domestic regulations. The process for issuing such ADs does not require public consultation, as determined by the Office of Best Practice Regulation, which has also found that ADs do not necessitate a Regulatory Impact Statement. This streamlined process ensures that safety directives are implemented promptly, without undue administrative delays.
