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.
CASA issued AD/NAV/3, affecting Navion model aircraft in 1972. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, provides the framework for the regulation of civil aviation within Australia, with an overarching objective of ensuring the safety of air navigation. One of the significant provisions of this Act is section 98, which empowers the Governor-General to make regulations for the purposes of the Act, thereby allowing for the creation of detailed safety standards. The Civil Aviation Safety Regulations 1998, made under this Act, further detail the requirements for maintaining the airworthiness of aircraft and aeronautical products. Regulation 39.001 of these Regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. ADs serve as the primary means for ensuring the continuing airworthiness of aircraft types and are mandated by international standards set out in Annex 8 to the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure safety in air navigation. These directives are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and regulated by the Legislative Instruments Act 2003. The State of Design, under Annex 8 of the Convention on International Civil Aviation, holds primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry. Australia’s State of Registry, represented by CASA, is tasked with ensuring the continuing airworthiness of aircraft registered in Australia, which includes assessing and potentially issuing Australian ADs when a State of Design issues a corresponding directive. This regulatory framework ensures that Australian aviation maintains high safety standards in alignment with international protocols.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) provide the legal basis for the issuance of airworthiness directives (ADs). According to regulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are thus legislative instruments as per section 6 of the Legislative Instruments Act 2003. ADs are a common method for ensuring the continuing airworthiness of aircraft types, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry to support this. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD for a type of aircraft on the Australian Register, the Civil Aviation Safety Authority (CASA) must assess this information and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design.
The obligations under these regulations primarily involve CASA, as Australia’s national airworthiness authority. CASA must review information provided by the State of Design and, if necessary, issue an Australian AD to ensure compliance with airworthiness standards. This process ensures that Australian aircraft meet international safety standards and are airworthy. CASA's role also includes assessing the need for ADs based on the safety risks identified by the State of Design and implementing these directives to maintain the continuing airworthiness of aircraft registered in Australia. The obligations further extend to the State of Registry, which must develop or adopt the necessary requirements to ensure the airworthiness of aircraft under its jurisdiction, in alignment with ADs issued by CASA.
In terms of penalties and consequences for non-compliance, the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences or penalties related to the issuance or enforcement of ADs. However, non-compliance with airworthiness directives can lead to severe consequences, including grounding of aircraft, which can result in significant operational disruptions and financial losses for operators. Furthermore, failure to comply with ADs can result in legal action by CASA, which may include fines or other enforcement actions. The severity of penalties for non-compliance can vary depending on the nature and impact of the non-compliance, but it is clear that adherence to ADs is critical to maintaining the safety and airworthiness of aircraft in Australia.
