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 US FAA has issued AD 2006-16-10 affecting Boeing B747 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/351, which will become effective on 28 September 2006.
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, Airframes 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 comprehensive framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation and operations. Under this Act, the Civil Aviation Safety Regulations 1998 were introduced to further detail the requirements for airworthiness and safety standards. Specifically, the Act authorises the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). These directives are critical for maintaining the safety and reliability of aircraft operating within Australian airspace and are based on obligations under the Convention on International Civil Aviation. The issuing of ADs is carried out in accordance with section 98 of the Act, with CASA acting on behalf of the Australian government to enforce these directives, ensuring they meet the policy objective of maintaining the highest safety standards in civil aviation.
Scope and Application
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, provides a legal framework for ensuring the safety of air navigation in Australia. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs are legislative instruments that mandate specific safety requirements to ensure the continuing airworthiness of aircraft, thereby aligning with international standards set by the Convention on International Civil Aviation, particularly Annex 8. The ADs are issued in response to directives from the State of Design, which is the state responsible for the design of the aircraft type, and must be assessed and, if necessary, adopted by CASA, Australia’s national airworthiness authority. The ADs are applicable to all entities and individuals involved in the operation of the affected aircraft types within Australia, ensuring compliance with both national and international safety standards. The ADs are not subject to public consultation or regulatory impact statements, reflecting their alignment with international obligations and the urgent nature of airworthiness issues.
Key Provisions
The key provisions of the Civil Aviation Safety Regulations 1998, particularly under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This is done under the authority granted by section 98 of the Civil Aviation Act 1988, which empowers the Governor-General to make regulations in the interests of air navigation safety. The ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments in accordance with the Legislative Instruments Act 2003.
These ADs impose certain obligations on CASA, the State of Design, and the State of Registry. The State of Design, in this case the USA for Boeing B747 model aircraft, has the responsibility to provide information necessary for the continuing airworthiness of the aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, acting as Australia’s national airworthiness authority, must assess the ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to ensure compliance with the safety requirements. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft within its jurisdiction.
Failure to comply with the requirements set forth in an AD can lead to significant consequences. Non-compliance can result in safety issues that may be considered an offence under the Civil Aviation Act 1988. The specific penalties for breaches of ADs are not detailed in the text, but generally, offences under the Act can lead to substantial fines or imprisonment, depending on the severity of the breach. CASA has the authority to enforce compliance through various measures, including grounding of non-compliant aircraft and other regulatory actions. These provisions and consequences underscore the importance of adhering to ADs to maintain the high safety standards expected in civil aviation.
