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 104/9 affecting De Havilland DH 104 (Dove) model aeroplanes not modified to Mod. 841, 842 and 843. CASA has assessed this AD and as a result has cancelled Australian AD/DHC 104/9. The cancellation will become effective on 20 November 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, enacted to provide a legal framework for the regulation of civil aviation in Australia, was introduced to ensure the safety of air navigation and the airworthiness of aircraft within Australia. This legislation allows the Governor-General to make regulations for these purposes, with the overarching goal of maintaining high safety standards in the aviation sector. The Civil Aviation Safety Regulations 1998 further detail these provisions, particularly under regulation 39.001 which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments, designed to address identified safety issues and ensure the continued airworthiness of aircraft. The Act, administered by CASA, aligns with international standards, particularly those set by the International Civil Aviation Organization (ICAO), to harmonise aviation safety practices globally. The legislative process, as outlined, does not require public consultation for AD cancellations due to international obligations, and such directives are deemed to not necessitate a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legal framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, which are designed to address safety issues and ensure the continuing airworthiness of aircraft. The ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and must comply with the Legislative Instruments Act 2003. This regulatory mechanism extends to all aircraft and aeronautical products within Australia, ensuring that the safety standards set forth are uniformly applied across the country. Notably, the ADs must align with the obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design provides essential information for continuing airworthiness to the States of Registry. Given the international nature of aviation, these directives are critical for harmonising safety standards across different jurisdictions.
Key Provisions
The Civil Aviation Act 1988 and its associated regulations provide the framework for ensuring the safety of air navigation in Australia. Section 98 of the Act allows the Governor-General to create regulations that serve the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are integral to maintaining the continuing airworthiness of aircraft and are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. Notably, the ADs are aligned with Annex 8 of the Convention on International Civil Aviation, which outlines the responsibilities of the State of Design and the State of Registry regarding the airworthiness of aircraft types.
Under these regulations, CASA has the authority to issue ADs that mandate specific actions to be taken by aircraft operators or owners to ensure that their aircraft meet the necessary safety standards. For example, AD/DH 104/9 was issued concerning De Havilland DH 104 (Dove) model aeroplanes that had not been modified to Mod. 841, 842, and 843. However, following a reassessment, CASA has decided to cancel this particular AD, effective from 20 November 2008, due to the resolution of the unsafe condition that initially prompted its issuance. Importantly, this cancellation aligns with Australia’s obligations under the Convention on International Civil Aviation and does not require consultation with the Australian public or a Regulatory Impact Statement.
The obligations imposed by these regulations extend to aircraft operators and owners, who must comply with the ADs issued by CASA. These directives often include mandatory inspections, repairs, or modifications to ensure that the aircraft continue to meet airworthiness standards. Failure to comply with an AD can lead to severe consequences, as these directives are legally binding. Under the Civil Aviation Act 1988, breaches of airworthiness directives can result in civil penalties, including fines and potential prosecution, as well as criminal penalties in cases of serious non-compliance. The specific maximum penalties for these offences are detailed in the Act and can include substantial fines and imprisonment, reflecting the critical nature of air safety regulations.
