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 2007-03-07 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/B737/201, Amendment 1, which will become effective on 12 April 2007. 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 provide a framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. Pursuant to section 98 of this Act, the Governor-General is empowered to make regulations for the purposes of the Act, ensuring that the overarching goal of maintaining aviation safety is upheld. Complementing this, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified kinds of aircraft or aeronautical products, as per regulation 39.001. These ADs are legislative instruments under the Legislative Instruments Act 2003 and are critical in communicating necessary information to maintain the continuing airworthiness of aircraft, aligning with Australia's commitments under the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, plays a pivotal role in ensuring that Australian aircraft meet international safety standards, particularly when issuing ADs in response to directives from the relevant State of Design, such as the United States for Boeing B737 models.
Scope and Application
The Civil Aviation Safety Regulations 1998 under the Civil Aviation Act 1988 apply to all aircraft and aeronautical products within Australia's jurisdiction, with the aim of ensuring the safety of air navigation. Regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. This regulatory framework is designed to ensure that the continuing airworthiness of aircraft is maintained in accordance with international standards set out in Annex 8 to the Convention on International Civil Aviation. The State of Design, which in this case is the United States for Boeing B737 model aircraft, is responsible for issuing ADs, while the State of Registry, represented by CASA in Australia, is tasked with assessing and implementing these directives to ensure compliance within its jurisdiction. The ADs are legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. Notably, these directives do not require public consultation or a Regulatory Impact Statement, as they are issued in response to international obligations and directives from the State of Design.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations that serve the Act's purpose and the safety of air navigation. According to regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) concerning certain aircraft or aeronautical products. These ADs are legislative instruments, as specified by subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003. This regulatory framework is established to ensure that aircraft maintain their airworthiness and meet safety standards.
Under the Convention on International Civil Aviation, particularly Annex 8, the State of Design has the primary responsibility for ensuring the ongoing airworthiness of an aircraft type, which involves providing necessary information to States of Registry. The State of Registry, in turn, is responsible for implementing requirements that ensure the airworthiness of individual aircraft. Consequently, when a State of Design issues an AD, the State of Registry must review the directive and, if necessary, issue a corresponding AD. For Australia, CASA performs this role and, upon assessment, has issued AD/B737/201, Amendment 1, effective from 12 April 2007, in response to the US Federal Aviation Administration's AD 2007-03-07.
Entities governed by these regulations face specific obligations and requirements. CASA, as the national airworthiness authority, must evaluate any ADs issued by the State of Design and decide whether to issue a corresponding AD for Australian aircraft. For the State of Registry, this means ensuring that all aircraft on the Australian Register comply with the mandated requirements. Operators of affected aircraft must adhere to the ADs, which may include conducting specific maintenance, inspections, or repairs to maintain airworthiness.
Failure to comply with ADs can lead to significant legal consequences. Under the Civil Aviation Act 1988, non-compliance can result in civil penalties, such as fines, or criminal charges for more severe breaches. The maximum penalties for breaches can vary, but they often include substantial fines for corporations and potential imprisonment for individuals, depending on the severity of the violation and the impact on aviation safety. These measures are in place to ensure that all stakeholders uphold the highest standards of airworthiness and safety in aviation.
