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/BEECH 76/17, affecting Beech 76 model aircraft in 1985. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as all affected aircraft would have been inspected, and, if necessary, modified long ago.
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 Commonwealth Parliament, serves to regulate civil aviation activities within Australia, with a primary focus on ensuring the safety of air navigation. In this context, the Civil Aviation Safety Regulations 1998 have been established to provide detailed rules and standards governing various aspects of civil aviation, including the issuance of airworthiness directives (ADs) under regulation 39.001. These ADs are critical legislative instruments designed to maintain the airworthiness of aircraft and aeronautical products, ensuring that they meet safety standards. The Civil Aviation Act 1988 and its associated regulations are instrumental in aligning Australia's civil aviation practices with international standards, particularly as outlined in Annex 8 to the Convention on International Civil Aviation. This legislative framework empowers the Civil Aviation Safety Authority (CASA) to mandate safety requirements, reflecting the overarching policy objective of safeguarding the public by maintaining high standards of airworthiness.
Scope and Application
The Civil Aviation Act 1988, as amended 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. These directives, which are legislative instruments, are issued to ensure the safety of air navigation in line with international standards set by the Convention on International Civil Aviation. The State of Design is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry, which then ensure the ongoing airworthiness of individual aircraft. CASA, as Australia’s national airworthiness authority, is mandated to assess information from the State of Design and issue Australian ADs as necessary. For example, CASA issued AD/BEECH 76/17 for Beech 76 model aircraft in 1985, but has since decided to cancel this directive as it no longer applies to aircraft on the Australian Register. This cancellation, which reduces the regulatory burden, does not require consultation with the Australian public or a Regulatory Impact Statement. The AD cancellation is made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the legislative framework established under the Civil Aviation Act.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to make regulations for the safety of air navigation. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs, as detailed in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments under section 6 of the Legislative Instruments Act 2003. This regulatory framework is intended to ensure the ongoing safety and airworthiness of aircraft operating in Australia.
The obligations placed on the parties by this legislation are significant. The State of Design, responsible for the aircraft type, must provide necessary information to ensure continuing airworthiness, as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the aircraft’s airworthiness. CASA, as Australia’s national airworthiness authority, has the duty to assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs. This ensures that all aircraft registered in Australia meet the required safety standards.
Failure to comply with the ADs can lead to serious consequences. Section 98 of the Civil Aviation Act 1988 allows for enforcement actions against any non-compliance with the regulations, including potential civil or criminal penalties. While the specific penalties are not detailed in the provided text, non-compliance with airworthiness directives can typically result in severe civil penalties, including fines, and in more severe cases, criminal charges. Such enforcement actions underscore the importance of adhering to the ADs to maintain the safety and airworthiness of aircraft.
