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/BELL 205/50 affecting Bell 205 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 12 March 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 acting 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, enacted by the Parliament of Australia, was introduced to regulate civil aviation in the interests of safety and national security. This Act provides the legal framework for the establishment and operation of the Civil Aviation Safety Authority (CASA), which is tasked with ensuring the safety of air navigation and the continuing airworthiness of aircraft. One of the key mechanisms CASA employs to maintain safety standards is through the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. ADs are legislative instruments designed to address safety issues with specific types of aircraft or aeronautical products, thereby ensuring compliance with international standards set forth by the Convention on International Civil Aviation. In the specific instance of AD/BELL 205/50, which affected Bell 205 aircraft, CASA reviewed and subsequently cancelled the directive due to Australia’s obligations under the Convention, rendering public consultation unnecessary. The cancellation took effect on 12 March 2009, with no replacement directive required, reflecting CASA's commitment to upholding both national and international safety standards.
Scope and Application
The Civil Aviation (Airworthiness) Amendment (Disallowance of Airworthiness Directive) Instrument 2009 pertains to the Civil Aviation Act 1988, providing a legal framework for the regulation of civil aviation in Australia. It applies to the Civil Aviation Safety Authority (CASA) and specifically relates to the issuance of airworthiness directives (ADs) concerning aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. The authority to issue ADs is exercised by CASA to ensure the safety of air navigation and the continuing airworthiness of aircraft, as required by Annex 8 to the Convention on International Civil Aviation. The scope of this Act extends to all aircraft registered in Australia, thereby affecting the State of Registry, which holds the responsibility for the continuing airworthiness of each aircraft. This Act has a national reach within Australia and is influenced by international obligations under the Convention on International Civil Aviation, particularly the role of the State of Design. Notably, the Act does not require public consultation for the issuance or cancellation of ADs, and no Regulatory Impact Statement is mandated as determined by the Office of Best Practice Regulation. The legislative instrument was made by the acting Manager, Airframes in the Airworthiness Engineering Group on behalf of CASA, following the appropriate legal procedures outlined in the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the process and authority for issuing airworthiness directives (ADs) in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the power to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003.
These airworthiness directives are essential for maintaining the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design holds the primary responsibility for ensuring the airworthiness of an aircraft type and must provide necessary information to the States of Registry. The State of Registry, in this case CASA, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. This regulatory framework ensures that aircraft meet safety standards and are maintained in a safe condition for operation.
The obligations imposed by these regulations on CASA and the State of Registry include the continuous monitoring and assessment of aircraft types and their components to ensure compliance with airworthiness standards. CASA, as the regulatory authority, must review existing ADs and make decisions based on international obligations, safety considerations, and operational requirements. For instance, CASA has issued, reviewed, and subsequently cancelled AD/BELL 205/50, which affected Bell 205 aircraft, effective from 12 March 2009, due to Australia’s obligations under the Convention on International Civil Aviation.
The cancellation of an AD, such as AD/BELL 205/50, is made without public consultation as it is determined that ADs do not require a Regulatory Impact Statement. The decision to cancel the AD was made by the acting Manager, Airframes in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act. While the cancellation of ADs may have significant implications for aircraft operators and maintenance providers, the regulations provide a clear process for such actions to ensure compliance with international safety standards.
Failure to comply with airworthiness directives can result in significant legal consequences. The Civil Aviation Safety Regulations 1998 include provisions for offences related to non-compliance with ADs. Penalties can include fines and imprisonment, with the exact penalties depending on the severity of the breach and the specific regulatory provisions breached. Additionally, operators and maintenance providers may face civil consequences, such as the grounding of aircraft, until compliance is achieved, which can have substantial financial and operational impacts.
