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/DH 104/11 affecting De Havilland DH 104 (Dove) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DH 104/11. 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 was enacted to provide a framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. It empowers the Governor-General to make regulations, including the issuance of airworthiness directives (ADs), to maintain safety standards. The Civil Aviation Safety Regulations 1998 further elaborate on these regulations, specifying that the Civil Aviation Safety Authority (CASA) can issue ADs for certain aircraft or aeronautical products. The Act and Regulations aim to uphold international safety standards as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design and the State of Registry are assigned specific responsibilities for the continuing airworthiness of aircraft. The Civil Aviation Safety Authority has exercised its powers to cancel an existing AD for De Havilland DH 104 (Dove) model aeroplanes, effective from 23 October 2008, as the unsafe condition identified no longer exists. This cancellation was made in accordance with Australia's obligations under the Convention on International Civil Aviation, and no public consultation was deemed necessary as ADs do not require a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, ensuring compliance with the Civil Aviation Act 1988. These directives serve as critical instruments for maintaining the safety and airworthiness of aircraft within Australia, aligning with the regulatory frameworks established under Annex 8 of the Convention on International Civil Aviation. The ADs are legislative instruments under section 46A of the Acts Interpretation Act 1901 and are subject to disallowance under the Legislative Instruments Act 2003. The State of Registry holds primary responsibility for the continuing airworthiness of individual aircraft, ensuring adherence to the safety standards set forth by international and domestic regulations. CASA’s issuance and subsequent cancellation of ADs, such as AD/DH 104/11 for De Havilland DH 104 (Dove) model aeroplanes, reflect the dynamic nature of aviation safety standards and the importance of international cooperation in maintaining airworthiness.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, particularly section 98, empower the Governor-General to make regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory mechanism is integral to maintaining the safety standards of aviation. Subregulation 39.001(5) further clarifies that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, therefore, are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and the accompanying regulations include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design must provide all necessary information to the States of Registry to maintain airworthiness. The State of Registry, in turn, is tasked with developing or adopting specific requirements to ensure the continuing airworthiness of individual aircraft, aligning with Annex 8. CASA’s role includes issuing ADs and ensuring that any ADs, such as the previously issued AD/DH 104/11 for De Havilland DH 104 (Dove) model aeroplanes, are assessed and, if necessary, cancelled once the unsafe condition no longer exists.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose several specific requirements on the parties they govern. These include the need for the State of Design to continuously provide necessary information to States of Registry, and for the States of Registry to implement and enforce airworthiness standards for individual aircraft. CASA is mandated to issue ADs, assess their continued necessity, and cancel them if the unsafe conditions no longer exist. For instance, the previously issued AD/DH 104/11 was cancelled by CASA on 23 October 2008 because the unsafe condition no longer existed.
In terms of offences, penalties, or consequences for breaches, the Act does not explicitly outline specific penalties for non-compliance with ADs within the provided text. However, the issuance and enforcement of ADs are critical to ensuring compliance with airworthiness standards. Failure to comply with ADs could potentially result in civil or criminal consequences, including fines or imprisonment, depending on the severity of the non-compliance and the resultant safety risks. The maximum penalties are not detailed in the provided text but are likely to be stipulated in other parts of the Civil Aviation Act 1988 or associated regulations.
