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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/ML-M4/9 affecting Maule M-4 model aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 12 February 2009. No replacement AD is required.
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, Airframes 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 the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. The Act empowers the Governor-General to create regulations for the purposes of the Act, particularly in the interests of air navigation safety. In this context, the Civil Aviation Safety Regulations 1998 were introduced to establish detailed safety standards and procedures. One significant aspect of these regulations is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) for specific types of aircraft or aeronautical products, as outlined in regulation 39.001. These ADs are legislative instruments, subject to disallowance and review, as stipulated in the Legislative Instruments Act 2003. This legislative framework is designed to ensure that Australia meets its international obligations under the Convention on International Civil Aviation, particularly those relating to the continuing airworthiness of aircraft, with the State of Design and the State of Registry playing crucial roles in this regard.
Scope and Application
The Civil Aviation Act 1988 provides the legislative foundation for ensuring the safety of air navigation in Australia. Under this Act, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs serve as a key regulatory mechanism to maintain the airworthiness of aircraft and aeronautical products, thereby safeguarding public safety. An AD is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is considered a legislative instrument according to the Legislative Instruments Act 2003. The issuance and cancellation of ADs are influenced by international obligations, such as Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of aircraft types. The State of Registry, in this case CASA, must also ensure the continuing airworthiness of individual aircraft within Australia, adhering to national and international standards. Notably, the AD/ML-M4/9 concerning Maule M-4 model aircraft has been cancelled, effective from 12 February 2009, due to Australia's commitments under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement was deemed necessary for this cancellation.
Key Provisions
The main provisions of the Civil Aviation Safety Regulations 1998, as they pertain to airworthiness directives, are outlined in regulation 39.001 (paragraph 1). This regulation grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives for specific types of aircraft or aeronautical products. These directives are legislative instruments and are subject to disallowance as per section 46A of the Acts Interpretation Act 1901. Furthermore, regulation 39.001(5) clarifies that airworthiness directives must align with the responsibilities and obligations under Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of aircraft types, and the State of Registry for the individual aircraft. This regulation ensures that CASA’s actions in issuing or cancelling directives are consistent with international obligations and standards.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA and other entities are significant. CASA must issue airworthiness directives when necessary to ensure the continuing airworthiness of aircraft types or aeronautical products (regulation 39.001). These directives must be issued in accordance with international conventions and standards, particularly Annex 8 to the Convention on International Civil Aviation. The State of Registry is also obligated to develop or adopt requirements that ensure the continuing airworthiness of aircraft, reflecting its responsibility under international agreements. Additionally, the State of Design must provide necessary information to support the airworthiness of aircraft types, ensuring that all stakeholders have the information needed to maintain safety standards.
Failure to comply with the provisions of the Civil Aviation Safety Regulations 1998 can result in significant consequences. Under regulation 39.001, non-compliance with an airworthiness directive may lead to safety risks, and in severe cases, criminal or civil penalties. While the specific penalties are not detailed in the provided text, non-compliance with aviation safety regulations can result in substantial fines and, in cases involving severe safety breaches, imprisonment. The maximum penalties for breaches can vary based on the severity of the breach and are outlined in the Civil Aviation Act 1988 and other related legislation. CASA has the authority to enforce these regulations and can take action against entities that fail to comply with airworthiness directives.
