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 206/28 affecting Cessna U206 model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 23 October 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 Manager, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, establishes the framework for civil aviation in Australia, aiming to ensure safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations that promote the safety of air navigation, which includes the issuance of airworthiness directives (ADs) to address safety concerns regarding aircraft types and aeronautical products. The Civil Aviation Safety Regulations 1998 further specify the authority of the Civil Aviation Safety Authority (CASA) to issue ADs, which are considered legislative instruments subject to disallowance. The objective of these ADs is to ensure the continuing airworthiness of aircraft in accordance with international standards, particularly those set by the International Civil Aviation Organization (ICAO). In line with these regulations and obligations, CASA has the authority to issue, amend, or cancel ADs based on the assessment of safety risks and the need to comply with international agreements.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia. This legislation empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that pertain to specific types of aircraft or aeronautical products. These ADs are legislative instruments that mandate the continuing airworthiness of aircraft registered in Australia, reflecting the obligations of the State of Registry under Annex 8 to the Convention on International Civil Aviation. The issuance of ADs is a critical measure to ensure that all aircraft maintain their airworthiness throughout their operational life. The authority to issue these directives is vested in CASA, the national airworthiness authority, which assesses any international airworthiness directives issued by the State of Design and determines if corresponding Australian ADs are necessary. For instance, CASA has assessed and subsequently cancelled an Australian AD for Cessna U206 model aircraft, effective from 23 October 2008, as the unsafe condition no longer exists. This process underscores CASA's commitment to safety and compliance with international standards, while also highlighting the specific roles of both the State of Design and the State of Registry in maintaining aircraft airworthiness.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations that ensure the safety of air navigation. These regulations can be implemented to protect the public and maintain the safety standards of aviation operations. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further delineates that the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and therefore, they are classified as legislative instruments as per section 6 of the Legislative Instruments Act 2003. This means that ADs have the force of law and are subject to parliamentary scrutiny.
The obligations imposed by these regulations include ensuring that the State of Design maintains the continuing airworthiness of an aircraft type and provides necessary information to the States of Registry. This is in accordance with Annex 8 to the Convention on International Civil Aviation. The State of Registry, in turn, has the responsibility of developing or adopting requirements to ensure the continuing airworthiness of aircraft registered within their jurisdiction. When an AD is issued by the State of Design for a type of aircraft on the Australian Register, CASA must review the information and, if deemed necessary, issue an Australian AD to enforce the State of Design’s requirements.
Failure to comply with ADs can result in serious consequences. Under the Civil Aviation Act 1988, it is an offence to operate an aircraft that does not meet the requirements set forth in an AD. This can lead to significant civil or criminal penalties. For instance, under section 67 of the Act, the maximum penalty for contravening an AD can be substantial, reflecting the seriousness of compromising air safety. It is crucial for aircraft operators and other stakeholders to adhere to ADs to prevent potential safety hazards and legal repercussions.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for ensuring the safety and airworthiness of aircraft through the issuance of ADs. These regulations impose specific obligations on States of Design and Registry to maintain airworthiness standards, with CASA playing a pivotal role in enforcing these standards in Australia. Non-compliance with ADs can lead to significant legal consequences, highlighting the importance of adhering to these directives to safeguard public safety.
