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/CESSNA 180/73 affecting Cessna 180 series aircraft in 1991. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition has long ceased to exist.
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 was enacted to provide a legislative framework for civil aviation in Australia, ensuring the safety, efficiency, and orderly development of air transport services. One of its key provisions allows the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under this authority, the Civil Aviation Safety Regulations 1998 were created, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are instrumental in maintaining the continuing airworthiness of aircraft and are a crucial tool in ensuring compliance with international safety standards as outlined in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Act 1988, through CASA's regulatory mechanisms, thus plays a vital role in safeguarding the aviation sector in Australia by mandating safety protocols and ensuring adherence to established aviation standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are integral to ensuring the safety of air navigation and are applicable to entities involved in the operation, maintenance, and design of aircraft within Australia. ADs serve as a means of continuing airworthiness information, mandated by Annex 8 to the Convention on International Civil Aviation, where the State of Design is responsible for providing necessary information to ensure the airworthiness of an aircraft type, and the State of Registry must ensure the continuing airworthiness of individual aircraft. The issuance of ADs is a legislative instrument as per section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. CASA’s role includes assessing ADs issued by other states and, if deemed appropriate, issuing Australian ADs to enforce the required safety measures. The cancellation of an existing AD, such as AD/CESSNA 180/73, is conducted by CASA when the unsafe condition it was addressing no longer exists, without necessitating a replacement AD or public consultation, as it reduces regulatory burden.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 provide a framework for the issuance of airworthiness directives (ADs). Under section 98 of the Act (1), the Governor-General has the authority to make regulations to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 (2) specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. Subregulation 39.001(5) (3) clarifies that ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 (4). Annex 8 to the Convention on International Civil Aviation (5) outlines the responsibilities of the State of Design and State of Registry in maintaining the continuing airworthiness of aircraft, with ADs serving as a key mechanism for disseminating necessary information.
The Act and Regulations impose several obligations on CASA and other parties involved in airworthiness. CASA, as Australia's national airworthiness authority, must assess information from the State of Design and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design (6). This ensures that Australian aircraft meet the necessary safety standards. The State of Registry is also responsible for ensuring the continuing airworthiness of aircraft on the Australian Register (7), developing or adopting appropriate requirements to meet this obligation. The State of Design, on the other hand, must provide necessary information to ensure the continuing airworthiness of an aircraft type (8).
Failure to comply with the provisions of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 can result in various consequences. While specific offences and penalties are not detailed in the text, the issuance of ADs is a regulatory mechanism to ensure compliance with airworthiness standards. Non-compliance with ADs could potentially lead to enforcement actions by CASA, including fines, suspension, or revocation of airworthiness certificates. The seriousness of the consequences would depend on the specific circumstances of non-compliance and the impact on aviation safety. However, the maximum penalties for such breaches are not outlined in the provided text.
