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 Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 185/15 affecting Cessna 185 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 185/15. The cancellation will become effective on 14 February 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the safety and efficiency of civil aviation in Australia, addressing the need for comprehensive regulation of air navigation and aircraft operations to ensure public safety and national security. Under this Act, the Governor-General is empowered to make regulations aimed at maintaining the safety of air navigation, with the Civil Aviation Safety Regulations 1998 further detailing these requirements. Notably, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows 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 under the Legislative Instruments Act 2003, serve as crucial tools for maintaining the continuing airworthiness of aircraft, in line with international standards set by the International Civil Aviation Organization (ICAO). CASA, acting as Australia’s national airworthiness authority, is responsible for assessing and, if necessary, issuing Australian ADs when corresponding directives are issued by the aircraft’s State of Design.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, establishes the framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Under this legislative arrangement, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products, aligning with the broader international obligations set out in Annex 8 to the Convention on International Civil Aviation. These directives are instrumental in maintaining the continuing airworthiness of aircraft and are issued by most International Civil Aviation Organization (ICAO) Contracting States. The ADs are legislative instruments, subject to disallowance and oversight as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The State of Registry, which in the case of Australia is CASA, is responsible for ensuring that ADs issued by the State of Design are appropriately assessed and implemented to safeguard the airworthiness of aircraft registered in Australia. The issuance, assessment, and potential cancellation of ADs are carried out by CASA, reflecting its role as the national airworthiness authority and its commitment to international aviation safety standards.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations that promote the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specified types of aircraft or aeronautical products. These directives are legislative instruments, as stipulated by subregulation 39.001(5) and the Acts Interpretation Act 1901, which are subject to disallowance. The legislative instruments are also governed by the provisions of the Legislative Instruments Act 2003.
Compliance with these regulations entails obligations for both the State of Design and the State of Registry. The State of Design, which is the country responsible for designing a specific type of aircraft, must ensure the continuing airworthiness of that aircraft type and provide necessary information to the State of Registry. The State of Registry, in this case, CASA as Australia’s national airworthiness authority, must evaluate this information and, if necessary, issue an Australian AD to enforce the requirements set forth by the State of Design. The State of Registry is also responsible for developing or adopting its own requirements to maintain the continuing airworthiness of aircraft registered within its jurisdiction.
In cases where an AD is issued by the State of Design, CASA must assess the information and, if appropriate, issue an Australian AD. This process was followed with AD/CESSNA 185/15, which affected Cessna 185 aircraft. CASA subsequently assessed the AD and decided to cancel Australian AD/CESSNA 185/15, effective from 14 February 2008. The cancellation was due to the unsafe condition addressed by the AD no longer existing, thus no replacement AD was required. Given the international obligations under the Convention on International Civil Aviation, no public consultation was undertaken regarding this AD cancellation. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement.
For any breach of the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, the Act provides for both civil and criminal consequences. Offences under the Act can result in penalties, with the maximum penalties varying depending on the severity of the breach. Civil penalties can include fines, while criminal penalties can include imprisonment. The exact penalties are detailed in the Act and would depend on the specific nature and circumstances of the offence. It is imperative for parties governed by these regulations to adhere strictly to the mandates to avoid facing such consequences.
