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 United States FAA has issued AD 2005-11-05 affecting Precise Flight Standby Vacuum Systems fitted to many aircraft by STC or local fitment. The United States is the State of Design for this equipment. CASA has assessed this AD and has issued Australian AD/INST/52, which will become effective on 27 October 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 provide a legal framework for the regulation of civil aviation in Australia, with a particular focus on ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations for the purposes of the Act, particularly those that safeguard air navigation safety, as stipulated in section 98. One significant aspect of the Act is the authority it grants to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives, which are legislative instruments, are essential for maintaining the continuing airworthiness of aircraft and aeronautical products in line with international standards set by the International Civil Aviation Organization (ICAO). The policy objective is to ensure that Australia adheres to its international obligations and maintains high safety standards in civil aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs, which are legislative instruments, are mandated to ensure the safety of air navigation and are in line with international standards set by the Convention on International Civil Aviation. Specifically, ADs are a common mechanism used by states to communicate necessary information for maintaining the continuing airworthiness of aircraft. The State of Design, which is responsible for the design of an aircraft type, must provide relevant information to States of Registry, which in turn must ensure the airworthiness of individual aircraft registered within their jurisdiction. For instance, CASA, as Australia’s national airworthiness authority, must assess information from the State of Design and issue corresponding ADs when necessary. This process was exemplified by CASA's issuance of AD/INST/52 in response to an AD issued by the United States Federal Aviation Administration for Precise Flight Standby Vacuum Systems. This AD, which became effective on 27 October 2005, was issued without public consultation and did not require a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to make regulations that are essential for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. Section 39.001(5) further specifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore, an AD qualifies as a legislative instrument according to section 6 of the Legislative Instruments Act 2003. This regulatory framework ensures that airworthiness directives are formal and enforceable instruments within the civil aviation regulatory system.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to take specific actions when an airworthiness directive is issued by a State of Design. The State of Design, as per Annex 8 to the Convention on International Civil Aviation, has the responsibility to ensure the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry. CASA, as Australia’s national airworthiness authority, must assess this information and, if deemed appropriate, issue an Australian AD to enforce the requirements of the State of Design. This process ensures that the safety standards set by the State of Design are implemented in Australia, thereby maintaining the airworthiness of aircraft registered within the country.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences, penalties, or consequences for breaches related to airworthiness directives. However, the issuance and enforcement of ADs are critical for maintaining the safety of air navigation. Failure to comply with an AD could potentially lead to civil or criminal liabilities under broader aviation safety laws. For example, non-compliance with airworthiness requirements could result in penalties under section 84 of the Civil Aviation Act 1988, which can include substantial fines and imprisonment, reflecting the severity of compromising aviation safety.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for issuing and enforcing airworthiness directives, ensuring that all relevant authorities, including CASA, can mandate safety requirements based on assessments by the State of Design. These regulations, while not specifying detailed penalties for non-compliance with ADs, are integral to the broader legal obligations that maintain the safety and airworthiness of aircraft within Australia.
