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.
The Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 180/4 Amdt 1 affecting Cessna 180 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 180/4 Amdt 1. The cancellation will become effective on 25 September 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, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation and operations. In this context, the Civil Aviation Safety Regulations 1998 were introduced to provide detailed provisions for maintaining safety standards within the industry. The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs serve as a key mechanism for ensuring the continuing airworthiness of aircraft, in line with the obligations under Annex 8 to the Convention on International Civil Aviation. The ADs are considered legislative instruments, as they are disallowable instruments under section 46A of the Acts Interpretation Act 1901. The Manager, Airframe and Structures, in the Airworthiness Engineering Group, issued a specific AD concerning Cessna 180 model aeroplanes, which has since been cancelled due to the resolution of the unsafe condition it was intended to address. This cancellation, reflecting Australia's commitment to international civil aviation standards, has been made by CASA in accordance with the Civil Aviation Act 1988, without the need for a Regulatory Impact Statement or public consultation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the regulation of airworthiness directives (ADs) in Australia, with the overarching aim of ensuring 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 specific types of aircraft or aeronautical products, establishing them as legislative instruments under the Legislative Instruments Act 2003. This regulatory mechanism is crucial for maintaining the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design is responsible for providing necessary information to ensure the continuing airworthiness of an aircraft type, while the State of Registry must adopt or develop requirements to ensure the airworthiness of individual aircraft within its jurisdiction. The cancellation of an AD, such as the AD/CESSNA 180/4 Amdt 1 affecting Cessna 180 model aeroplanes, is a decision made by CASA in accordance with the Act and reflects Australia's compliance with international obligations. Notably, the cancellation of an AD does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 (section 98) allows the Governor-General to create regulations that ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 provides the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments under the Acts Interpretation Act 1901 and are subject to disallowance. Subregulation 39.001(5) further clarifies that ADs fall under the legislative instruments category, and they are subject to the rules outlined in the Legislative Instruments Act 2003.
The State of Design, as per Annex 8 of the Convention on International Civil Aviation, bears the primary responsibility for the continuing airworthiness of aircraft types. This includes providing necessary information to the States of Registry to ensure the ongoing airworthiness of those aircraft types. The State of Registry, in turn, is responsible for ensuring the continuing airworthiness of individual aircraft within its jurisdiction. They must develop or adopt appropriate requirements to maintain airworthiness. This international framework is reflected in the Australian context through the issuance of ADs by CASA, as demonstrated in the case of AD/CESSNA 180/4 Amdt 1 affecting Cessna 180 model aeroplanes.
The AD/CESSNA 180/4 Amdt 1, issued by CASA, has been assessed and subsequently cancelled. The cancellation is effective from 25 September 2008, and no replacement AD is required as the unsafe condition addressed by the directive no longer exists. This cancellation aligns with Australia's obligations under the Convention on International Civil Aviation, hence there was no need for public consultation or a Regulatory Impact Statement by the Office of Best Practice Regulation. The AD was issued by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988.
The cancellation of AD/CESSNA 180/4 Amdt 1 underscores the rigorous processes in place to ensure the safety and airworthiness of aircraft. CASA's decision to cancel the directive reflects its commitment to maintaining high safety standards in accordance with international obligations. The legislative and regulatory framework ensures that all parties involved in aircraft operations are aware of their responsibilities and the consequences of non-compliance. Failure to adhere to ADs and other safety regulations can result in serious civil or criminal consequences, including fines and imprisonment, depending on the severity of the breach.
