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 issued AD 2007-07-07, affecting General Electric CF 34 series engines. The United States is the State of Design for this engine series. CASA has amended the equivalent Australian AD to AD/CF34/5 Amendment 2. The amended AD will become effective on 7 June 2007. This AD cancels and replaces the previous issue.
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 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 was enacted to provide a legal framework for the regulation of civil aviation in Australia, with a strong emphasis on safety. This Act empowers the Governor-General to make regulations that ensure the safety of air navigation, which is critical in maintaining the high standards of air travel and aviation activities within the country. Complementing this legislation, the Civil Aviation Safety Regulations 1998 further elaborate on specific regulatory requirements, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These directives are legislative instruments made under the authority of the Civil Aviation Act and are essential for maintaining the continuing airworthiness of aircraft and aeronautical products as stipulated by international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, plays a crucial role in ensuring that aircraft meet safety standards by issuing these directives, which are often in response to actions taken by the aircraft’s State of Design. This legislative framework ensures that Australia adheres to international obligations and maintains a robust and consistent approach to aviation safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs are legislative instruments as defined under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The ADs serve to ensure the continuing airworthiness of aircraft types, aligning with the responsibilities of the State of Design and the State of Registry as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is tasked with assessing and, when necessary, issuing Australian ADs to comply with the requirements set forth by the State of Design. In the case of General Electric CF 34 series engines, following the issuance of AD 2007-07-07 by the United States Federal Aviation Administration, CASA has updated its AD to AD/CF34/5 Amendment 2, effective from 7 June 2007. This AD replaces the previous issue and was made without public consultation due to Australia’s obligations under the Convention on International Civil Aviation and in response to the State of Design’s AD.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, provides the foundation for the issuance of regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This regulatory mechanism is vital for maintaining the safety and airworthiness of aircraft operating in Australia. Section 39.001(5) further clarifies that ADs are disallowable instruments, and thus, legislative instruments in accordance with the Legislative Instruments Act 2003.
These airworthiness directives serve as crucial tools in ensuring the continuing airworthiness of aircraft. Under the Convention on International Civil Aviation, specifically Annex 8, the State of Design, which is responsible for the design of an aircraft, holds the primary responsibility for maintaining the continuing airworthiness of the aircraft type. This responsibility includes providing necessary information to the States of Registry, which are responsible for individual aircraft. When the State of Design issues an AD, the State of Registry, in this case CASA as Australia's national airworthiness authority, must assess this information and, if necessary, issue an equivalent Australian AD to ensure compliance with the safety standards.
The obligations placed on parties and entities governed by this legislation are clear and significant. CASA, as the national airworthiness authority, must rigorously assess any ADs issued by the State of Design and, if deemed necessary, issue corresponding ADs in Australia. This ensures that all aircraft registered in Australia meet the necessary safety standards. Additionally, aircraft operators and owners must comply with the requirements set out in these ADs, which may include mandatory inspections, repairs, and modifications. Failure to comply with these directives can result in severe consequences, including the grounding of aircraft and potential legal penalties.
The legislation also delineates the consequences for non-compliance with airworthiness directives. Breach of an AD can lead to serious civil and criminal penalties. For instance, if an aircraft operator fails to comply with an AD, CASA can take enforcement actions, which may include fines, suspension of the aircraft’s certificate of airworthiness, or even criminal charges against the operator. The severity of the penalties reflects the critical nature of airworthiness directives in maintaining the safety of air navigation. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 thus provide a robust framework for ensuring that all stakeholders adhere to the highest safety standards, thereby protecting the public and maintaining the integrity of the aviation industry.
