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. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
The Civil Aviation Safety Authority or its predecessors issued AD/SUPP/6 affecting Air Equipment hoists P/No’s 76375, 76375-02 and 76375-100. CASA has assessed this AD and as a result has cancelled Australian AD/SUPP/6. The cancellation will become effective on 9 April 2009. 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 framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. One of its key provisions allows the Governor-General to make regulations under section 98, which serve the interests of air navigation safety. The Civil Aviation Safety Regulations 1998, made pursuant to this Act, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments and are critical for maintaining the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. The problem or gap addressed by this legislation is ensuring the safety of air navigation and the continuing airworthiness of aircraft through regulatory oversight and compliance with international standards. The authority to issue ADs and the subsequent cancellation of an AD, such as AD/SUPP/6 affecting Air Equipment hoists, is exercised by CASA under the authority granted by the Act, reflecting the commitment to international safety standards and the efficient management of aviation risks.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are instrumental in maintaining the continuing airworthiness of aircraft and are a common practice among ICAO Contracting States, including Australia. The State of Design holds the primary responsibility for ensuring the airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure the continuing airworthiness of aircraft registered within Australia. When a State of Design issues an AD, CASA is mandated to evaluate this information and, if necessary, issue an Australian AD to enforce the requirements set forth by the State of Design. The issuance, amendment, or cancellation of an AD is a legislative instrument, subject to disallowance and scrutiny under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The scope of the AD extends to all relevant entities within the aviation industry, including aircraft manufacturers, operators, and maintenance organisations, ensuring compliance with safety standards. This legislation 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 the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for issuing airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 authorises the Governor-General to make regulations, including ADs, for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are considered disallowable instruments under the Acts Interpretation Act 1901, and therefore they are legislative instruments as defined in the Legislative Instruments Act 2003.
Under these regulations, CASA, as Australia’s national airworthiness authority, must assess any AD issued by the State of Design and, if necessary, issue a corresponding Australian AD to ensure compliance with the requirements of the State of Design. This process ensures that the continuing airworthiness of aircraft registered in Australia is maintained in accordance with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design has the primary responsibility for the airworthiness of an aircraft type, while the State of Registry, such as CASA, is responsible for ensuring the continuing airworthiness of individual aircraft.
The obligations imposed by these regulations on the parties governed by them are clear and specific. CASA must diligently assess any AD issued by the State of Design and determine if it is appropriate to issue an Australian AD. When a State of Design issues an AD, CASA must evaluate the information provided and decide whether the same or similar requirements should be mandated for Australian-registered aircraft. Additionally, the State of Registry must develop or adopt the necessary requirements to ensure the continuing airworthiness of aircraft within its jurisdiction.
Failure to comply with the requirements set forth in the ADs can result in significant consequences. While the specific offences and penalties are not detailed in the text, it is reasonable to infer that non-compliance with ADs could lead to severe civil or criminal penalties, considering the critical nature of airworthiness directives in maintaining aviation safety. These penalties could include fines, imprisonment, or other sanctions as prescribed by the relevant aviation safety legislation.
