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 185/27 affecting Cessna 185 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 3 July 2008. No replacement AD is required.
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 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, enacted by the Australian Parliament, serves to regulate civil aviation activities within Australia, ensuring that these activities are conducted safely and efficiently. One significant aspect of this Act is its provision for the creation of regulations to maintain the safety of air navigation. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft and aeronautical products, as outlined in the Civil Aviation Safety Regulations 1998. These directives are critical for ensuring the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. The process of issuing and cancelling ADs, as demonstrated in the case of AD/CESSNA 185/27 affecting Cessna 185 aircraft, is integral to maintaining safety standards and adhering to Australia's obligations under international agreements. The cancellation of such directives, which in this case has been carried out due to Australia's obligations under the Convention, underscores the importance of continuous assessment and compliance with international airworthiness standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations allow CASA to mandate requirements for ensuring the continuing airworthiness of aircraft types registered in Australia. The authority to issue ADs stems from section 98 of the Civil Aviation Act 1988 and is further detailed in regulation 39.001 of the Civil Aviation Safety Regulations 1998. Notably, ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments under the Legislative Instruments Act 2003. These directives align with Annex 8 of the Convention on International Civil Aviation, which places the responsibility of continuing airworthiness on the State of Design, with the State of Registry ensuring compliance on an individual aircraft basis. CASA's role as Australia’s national airworthiness authority involves assessing information from the State of Design and issuing Australian ADs as necessary. The issuance and cancellation of such directives are integral to maintaining safety standards and ensuring compliance with international aviation regulations.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, allows for the creation and enforcement of airworthiness directives (ADs) to ensure the safety of air navigation (sections 98 and 39.001). These ADs serve as a legislative instrument under the Legislative Instruments Act 2003 (section 6) and are essential for maintaining the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, typically the country where the aircraft is designed, bears the primary responsibility for providing necessary information to ensure the continuing airworthiness of an aircraft type, which is then adopted by the State of Registry, where the aircraft is registered, as mandated by Annex 8. In Australia, the Civil Aviation Safety Authority (CASA) is the national airworthiness authority responsible for assessing information provided by the State of Design and issuing Australian ADs to enforce those requirements.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA and other entities include ensuring that any AD issued mandates the necessary requirements for maintaining the airworthiness of the affected aircraft. CASA must review and assess the information provided by the State of Design and, if appropriate, issue an Australian AD. This process ensures that all aircraft registered in Australia meet the necessary safety standards. The State of Registry is also required to develop or adopt requirements to ensure the continuing airworthiness of aircraft, ensuring that each aircraft remains in a safe condition for operation. These obligations ensure that both the State of Design and the State of Registry collaborate to maintain the highest safety standards for aircraft in operation.
Failure to comply with an airworthiness directive or any regulations set forth by CASA can result in significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to civil penalties, including fines. The exact penalties can vary depending on the severity of the non-compliance and are determined by the court. Additionally, in cases of serious non-compliance, CASA may take enforcement actions, including grounding of aircraft, which can have severe operational and financial repercussions for the aircraft owner or operator. The Civil Aviation Safety Regulations 1998 further delineate the enforcement mechanisms and provide for the imposition of penalties for breaches, thereby ensuring that safety standards are upheld and that any violations are appropriately sanctioned.
