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 French DGAC has issued Emergency AD UF-2005-120 affecting Airbus A320 aircraft. France is the State of Design for Airbus A320 aircraft. CASA has assessed this AD and has issued Australian AD/A320/179 original issue, which will become effective on 12 July 2005.
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, New Technologies and Systems, 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 comprehensive framework for civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. The Act grants the Governor-General the authority to create regulations that support the Act’s objectives, particularly focusing on the safety of air navigation. One significant regulation under this Act is the Civil Aviation Safety Regulations 1998, which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are essential tools for maintaining the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, evaluates ADs issued by the State of Design and, if necessary, issues corresponding Australian ADs to comply with international obligations and ensure safety. The issuance of these ADs is carried out in accordance with the legislative framework provided by the Civil Aviation Act 1988, reflecting the commitment to harmonising national regulations with international standards.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that apply to specified kinds of aircraft or aeronautical products. This regulatory framework is designed to ensure the safety of air navigation and the continuing airworthiness of aircraft. ADs, which are legislative instruments under section 6 of the Legislative Instruments Act 2003, are typically issued in response to identified safety issues and are aligned with the requirements of the International Civil Aviation Organization (ICAO) as detailed in Annex 8 to the Convention on International Civil Aviation. The State of Design holds responsibility for the initial airworthiness of an aircraft type, while the State of Registry is tasked with ensuring the continuing airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, must evaluate ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to mandate compliance. In the case of the French DGAC's Emergency AD UF-2005-120 affecting Airbus A320 aircraft, CASA assessed the directive and issued Australian AD/A320/179, effective from 12 July 2005. This process adheres to Australia's obligations under the Convention on International Civil Aviation, and the nature of ADs does not necessitate public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the framework for issuing airworthiness directives (ADs) under section 98 and regulation 39.001 respectively. ADs are regulatory instruments issued by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft. These directives are considered legislative instruments under the Legislative Instruments Act 2003 and are issued to comply with international obligations under the Convention on International Civil Aviation.
The obligations imposed by these provisions require the State of Design to provide necessary information to ensure the continuing airworthiness of aircraft types. The State of Registry must then develop or adopt requirements to maintain the airworthiness of individual aircraft registered within their jurisdiction. In Australia, CASA is responsible for assessing foreign ADs issued by the State of Design and issuing corresponding Australian ADs when necessary. This ensures that Australian aircraft meet the same safety standards as those set by the State of Design. The process does not involve public consultation or a Regulatory Impact Statement, as these ADs are issued in response to international obligations and assessments by CASA.
The Act and Regulations establish clear roles and responsibilities for both the State of Design and the State of Registry, ensuring that all parties involved in aircraft airworthiness adhere to internationally recognised safety standards. CASA's role is pivotal in assessing foreign ADs and issuing Australian ADs to mandate necessary safety measures. This systematic approach ensures that Australian aircraft remain compliant with global safety standards and that any identified safety issues are promptly addressed.
Breaching the requirements set out in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in significant penalties. The Act does not specify particular offences or penalties for non-compliance with ADs, but non-compliance with airworthiness requirements can lead to severe consequences, including the potential grounding of aircraft and enforcement actions by CASA. The consequences of failing to comply with ADs can also include civil or criminal liability, depending on the severity of the breach and its impact on aviation safety. The exact penalties for non-compliance may vary but can include fines and imprisonment, reflecting the serious nature of aviation safety violations.
