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 Malaysian DCA has issued AD CAM AD 001-01-2004 R1 affecting Eagle X-TS model aircraft. Malaysia is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/X-TS/5, Amendment 2, which will become effective on 11 May 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, Airframes 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 was enacted to establish a legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation, as outlined in section 98. In accordance with regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. These directives are legislative instruments under the Legislative Instruments Act 2003 and serve as crucial tools for maintaining the continuing airworthiness of aircraft, a responsibility primarily held by the State of Design, as stipulated in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is tasked with assessing such directives and issuing corresponding Australian ADs as necessary.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes the framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Under this legislation, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products, in accordance with regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs, which are legislative instruments as per the Legislative Instruments Act 2003, are crucial for maintaining the continuing airworthiness of aircraft and are issued in response to requirements set by the State of Design or Registry. For instance, when Malaysia, as the State of Design, issues an AD affecting the Eagle X-TS model aircraft, CASA, as Australia’s national airworthiness authority, evaluates this directive and issues its own corresponding AD to enforce the necessary requirements on aircraft registered in Australia. Notably, the issuance of these ADs is governed by international obligations under the Convention on International Civil Aviation and does not necessitate public consultation or a Regulatory Impact Statement. This AD, issued under the authority of the Act, aims to uphold safety standards consistent with international obligations and the safety of air navigation within Australia.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Specifically, section 98 of the Act allows the Governor-General to create regulations for air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables CASA to issue these directives. These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are therefore legislative instruments as per section 6 of the Legislative Instruments Act 2003. This regulatory framework ensures that all parties involved in civil aviation adhere to safety standards that are internationally recognised.
In line with Annex 8 of the Convention on International Civil Aviation, the State of Design has the overarching responsibility for ensuring the continuing airworthiness of an aircraft type. This includes providing any necessary information to the States of Registry to maintain the safety of aircraft in operation. The State of Registry, in turn, must develop or adopt 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 must assess this information and, if necessary, issue an Australian AD to enforce the requirements set by the State of Design. For example, the Malaysian Department of Civil Aviation (DCA) issued AD CAM AD 001-01-2004 R1 for the Eagle X-TS model aircraft, leading CASA to issue Australian AD/X-TS/5, Amendment 2, effective from 11 May 2006.
The obligations under these regulations are clear. CASA must promptly assess any ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs to ensure compliance with international safety standards. This process ensures that aircraft registered in Australia meet the necessary safety requirements. Additionally, the State of Registry must ensure that individual aircraft are maintained in a safe and airworthy condition in accordance with the requirements set by CASA. These obligations are integral to maintaining the safety and reliability of the civil aviation system in Australia.
Failure to comply with ADs can lead to serious consequences. Non-compliance with ADs can result in enforcement actions against the aircraft operator, including fines and potential grounding of the aircraft. Under the Civil Aviation Act 1988, the maximum penalty for non-compliance can include substantial fines and, in severe cases, imprisonment. Additionally, the safety and operational integrity of the aircraft can be compromised, leading to increased risk of accidents. Therefore, adherence to ADs is crucial to maintaining the highest safety standards in civil aviation.
