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/DHC-1/14 affecting De Havilland DHC-1 (Chipmunk) model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHC-1/14. 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 ensure the safety of air navigation in Australia, providing a legal framework for the regulation of civil aviation activities. This legislation allows for the creation of regulations that are essential for the safety of air navigation, as outlined in section 98 of the Act. The Civil Aviation Safety Regulations 1998 were introduced to further this goal by detailing specific requirements for airworthiness and operational safety, including the ability to issue airworthiness directives as per regulation 39.001. These directives, which are legislative instruments under the Legislative Instruments Act 2003, are crucial for maintaining the continuing airworthiness of aircraft and aeronautical products. The Civil Aviation Safety Authority (CASA) has the authority to issue such directives, which align with international standards set by the International Civil Aviation Organization (ICAO) under Annex 8 of the Convention on International Civil Aviation. This legislative framework ensures that Australia's aviation safety regulations are consistent with global standards, promoting a safe and reliable aviation system both domestically and internationally.
Scope and Application
The Civil Aviation Act 1988, alongside the Civil Aviation Safety Regulations 1998, governs the safety of air navigation in Australia and allows the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft and aeronautical products. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables CASA to issue ADs for specific kinds of aircraft or aeronautical products, which are considered legislative instruments under the Legislative Instruments Act 2003. The ADs serve as a means of compliance with the Convention on International Civil Aviation, specifically Annex 8, which mandates the State of Design to provide necessary information to ensure airworthiness. In Australia, CASA, acting as the State of Registry, has the responsibility to ensure the continuing airworthiness of aircraft. This includes the authority to cancel an AD, such as AD/DHC-1/14 affecting De Havilland DHC-1 model aeroplanes, if the unsafe condition addressed by the AD no longer exists. The cancellation of such ADs is made in accordance with the Act and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The main operative sections of this legislation pertain to the issuing of airworthiness directives (ADs) as outlined in section 98 of the Civil Aviation Act 1988, and regulation 39.001 of the Civil Aviation Safety Regulations 1998. Section 98 allows the Governor-General to make regulations that serve the interests of air navigation safety, while regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These directives are essential for ensuring the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design has the overarching responsibility for maintaining the airworthiness of aircraft types.
The obligations imposed by the Act and the Regulations on parties such as CASA, States of Design, and States of Registry are significant. CASA, as the regulatory body, must issue ADs when necessary to address safety concerns, in line with Australia’s obligations under international conventions. The State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type, while the State of Registry is tasked with implementing the ADs to maintain the airworthiness of individual aircraft. These entities must work collaboratively to ensure that safety standards are met and maintained.
Failing to comply with the ADs can result in severe consequences. While specific offences and penalties are not detailed in this excerpt, breaches of safety regulations generally carry significant civil and criminal penalties. The seriousness of these penalties is underscored by the fact that ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. Infractions may lead to enforcement actions by CASA, potentially resulting in fines, operational restrictions, or other legal actions against the non-compliant party. The exact penalties depend on the nature and severity of the breach, but they are designed to ensure stringent adherence to safety standards to protect public safety.
