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 United States FAA has issued AD 2005-16-14 affecting Gulfstream Aerospace Corporation G-IV, GIV-X, GV and GV-SP model aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/G1159/44, which will become effective on 2 September 2005.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, 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, addresses the overarching legal framework for civil aviation in the country, ensuring safety and regulatory compliance within the aviation industry. As part of this framework, the Civil Aviation Safety Regulations 1998 provide specific regulatory measures to maintain airworthiness standards. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. This legislative instrument is intended to ensure that aircraft remain in a condition that allows for safe operation, fulfilling Australia's obligations under the Convention on International Civil Aviation. The ADs serve as a mechanism for CASA to mandate requirements based on assessments of directives issued by the State of Design, thereby maintaining the continuing airworthiness of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, mandates that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products. These ADs apply to specific kinds of aircraft or aeronautical products, and in the case of aircraft registered in Australia, they must comply with the directives issued by CASA. The ADs are legislative instruments and are required by Australia’s obligations under the Convention on International Civil Aviation. The State of Registry, in this case CASA, is responsible for the continuing airworthiness of aircraft on the Australian Register, and must adopt or develop requirements to ensure compliance with these ADs. Exemptions or exclusions from ADs are not typically applicable, as they are designed to maintain the highest safety standards. Subordinate instruments may extend or further detail the application of these ADs, but the primary focus remains on ensuring the safety of air navigation.
Key Provisions
The Civil Aviation Act 1988, as supported by the Civil Aviation Safety Regulations 1998, lays out the framework for the issuance of airworthiness directives (ADs) under section 98 and regulation 39.001. An AD is a legislative instrument that the Civil Aviation Safety Authority (CASA) can issue for specific kinds of aircraft or aeronautical products to ensure safety in air navigation. These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and they adhere to the requirements set out in the Legislative Instruments Act 2003. The State of Design, which is the country where the aircraft type is designed, holds the primary responsibility for the continuing airworthiness of the aircraft type and must provide necessary information to the State of Registry, which is the country where the aircraft is registered. CASA, acting as Australia’s national airworthiness authority, evaluates the ADs issued by the State of Design and may issue corresponding Australian ADs to enforce the same requirements.
Obligations imposed by these regulations include ensuring that the State of Design provides all necessary information for the continuing airworthiness of aircraft types. The State of Registry must establish or adopt the requisite requirements to ensure the aircraft’s continuing airworthiness. CASA is obligated to review any ADs issued by the State of Design and to issue Australian ADs as necessary, ensuring that the aircraft registered in Australia meet the required safety standards. Additionally, the State of Registry must take steps to ensure compliance with these ADs by the aircraft operators within its jurisdiction.
Failure to comply with the requirements set forth in an AD can lead to significant legal consequences. Under the Civil Aviation Act 1988, any person who contravenes an AD commits an offence. The penalties for such offences can include substantial fines and, in severe cases, imprisonment. The exact penalties are determined by the severity of the breach and the specific provisions of the AD in question. Additionally, non-compliance can result in the grounding of aircraft, which can have severe operational and financial repercussions for the operators. It is crucial for all parties involved to adhere to the ADs to maintain the safety standards required by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998.
