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 82/4 affecting De Havilland DH 82 (Tiger Moth) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DH 82/4. 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, 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 provide a comprehensive legal framework for civil aviation in Australia, addressing issues related to the safety, efficiency, and economic development of the aviation industry. Under this Act, the Governor-General is empowered to make regulations aimed at ensuring the safety of air navigation, thereby safeguarding public safety and promoting the responsible operation of aircraft within Australian airspace. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, specifically enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs serve as legislative instruments that mandate safety measures and compliance with aviation standards. The Civil Aviation Act 1988 and its accompanying regulations are designed to align with international standards, particularly those set by the International Civil Aviation Organization (ICAO), ensuring that Australia's aviation safety regime is consistent with global best practices.
Scope and Application
The Civil Aviation Act 1988 provides the legal foundation for ensuring the safety of air navigation in Australia, empowering the Governor-General to make regulations under section 98 that contribute to this objective. Pursuant to this authority, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products as per regulation 39.001. These ADs, which are subject to disallowance under the Acts Interpretation Act 1901 and are legislative instruments according to the Legislative Instruments Act 2003, serve as essential tools for maintaining the continuing airworthiness of aircraft, in line with international standards set by Annex 8 to the Convention on International Civil Aviation. The State of Design is responsible for the airworthiness of an aircraft type, while the State of Registry must ensure the ongoing airworthiness of individual aircraft, developing or adopting the necessary requirements to achieve this. In the specific case of the cancellation of Australian AD/DH 82/4 affecting De Havilland DH 82 (Tiger Moth) model aeroplanes, CASA has determined that the unsafe condition no longer exists, thus rendering a replacement AD unnecessary. This decision has been made in accordance with Australia's international obligations, and consequently, no public consultation or Regulatory Impact Statement has been required.
Key Provisions
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation. Section 98 of the Act allows the Governor-General to make regulations for this purpose, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are legislative instruments that can be disallowed under section 46A of the Acts Interpretation Act 1901 and must comply with the requirements of the Legislative Instruments Act 2003.
These airworthiness directives serve to maintain the continuing airworthiness of aircraft in accordance with international standards. Under Annex 8 to the Convention on International Civil Aviation, the State of Design holds primary responsibility for ensuring the airworthiness of an aircraft type, and must provide necessary information to States of Registry. The State of Registry, in turn, must develop or adopt requirements to maintain airworthiness, as exemplified by CASA's issuance of AD/DH 82/4 for De Havilland DH 82 (Tiger Moth) aeroplanes. This directive has since been cancelled, effective from 23 October 2008, because the unsafe condition it addressed no longer exists. The cancellation was made in compliance with Australia’s obligations under the Convention and did not require public consultation or a Regulatory Impact Statement.
The obligations imposed by the Act and Regulations on parties and entities include ensuring the ongoing safety and airworthiness of aircraft. CASA, as the regulator, must issue ADs where necessary to address safety issues. Aircraft owners and operators must comply with ADs relevant to their aircraft, ensuring that any required modifications or inspections are carried out in a timely manner. The State of Registry must also ensure that the continuing airworthiness of aircraft is maintained, which involves monitoring compliance with ADs and other regulatory requirements.
Failure to comply with an airworthiness directive can result in significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can be considered an offence, potentially leading to criminal charges. The maximum penalties for such offences can include substantial fines and imprisonment, depending on the severity of the breach and its impact on safety. Additionally, non-compliance can result in civil penalties, such as fines or the grounding of an aircraft, further underscoring the importance of adhering to ADs to maintain the highest safety standards in aviation.
