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 2006-10-16 affecting Boeing B747 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and as a result has cancelled Australian AD/B747/271. The cancellation will become effective on 6 July 2006. No replacement AD is required, as the original unsafe condition has been corrected by AD/B747/294 Amendment 1.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, and because it is cancelled in response to an AD raised by the relevant State of Design, no consultation with the Australian public has taken place on this AD cancellation. 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 legal framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the sector. This Act empowers the Governor-General to make regulations that support the Act's objectives, particularly focusing on the safety of air navigation. In line with this, the Civil Aviation Safety Regulations 1998 were established to provide detailed rules and standards for civil aviation safety, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs serve as legislative instruments to mandate specific safety measures and are crucial for maintaining the continuing airworthiness of aircraft. The ADs align with international standards, particularly under Annex 8 of the Convention on International Civil Aviation, which places responsibility for the continuing airworthiness of aircraft types on the State of Design and requires States of Registry to implement the necessary measures to ensure safety. This legislation aims to harmonise Australia's aviation safety practices with international standards, ensuring that the Australian public is protected while maintaining robust and efficient aviation safety protocols.
Scope and Application
The Civil Aviation Safety Regulations 1998, made under the Civil Aviation Act 1988, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These directives are legislative instruments that apply to aircraft registered in Australia, ensuring compliance with international standards for continuing airworthiness as mandated by the Convention on International Civil Aviation. ADs are critical in maintaining the safety of aircraft and are issued by the State of Design, with the State of Registry responsible for implementing these directives. In the case of the Boeing B747 model, CASA has cancelled an existing AD in response to an updated directive from the US Federal Aviation Administration, the State of Design, thereby aligning with international obligations and ensuring that Australian aviation standards remain consistent with global practices. This regulatory action does not require public consultation or a Regulatory Impact Statement, as it pertains to the specific obligations under the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations necessary for the safety of air navigation. Regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. The Convention on International Civil Aviation, particularly Annex 8, places the responsibility of ensuring an aircraft type's continuing airworthiness on the State of Design, which must provide necessary information to the State of Registry. Consequently, CASA, as Australia’s national airworthiness authority, must assess and issue corresponding ADs if necessary, to comply with international standards and ensure the safety of aircraft registered in Australia.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on the parties involved are significant. The State of Design, which in the case of Boeing B747 model aircraft is the United States, must issue ADs to address safety issues. CASA, representing the State of Registry, is obligated to review these ADs and determine their applicability to aircraft registered in Australia. If an AD is deemed necessary, CASA must issue a corresponding Australian AD to mandate the required safety measures. This ensures that Australian aircraft meet international safety standards and comply with domestic regulations. Additionally, the State of Registry, which in this case is Australia, must develop or adopt requirements that ensure the continuing airworthiness of all aircraft registered within its jurisdiction.
Failure to comply with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in serious consequences. The Act outlines various offences and penalties for non-compliance, which can include both civil and criminal liabilities. For instance, if an aircraft operator fails to adhere to an AD, CASA may take enforcement action, which could range from fines to the suspension or revocation of the operator’s licence. The severity of the penalties can vary depending on the nature and extent of the non-compliance, but they are designed to ensure that all parties maintain the highest standards of airworthiness and safety. In the event of a serious breach, individuals or corporations may face criminal charges, which could lead to imprisonment.
The Civil Aviation Safety Regulations 1998 also detail the process for issuing and cancelling ADs. For example, in the case of AD 2006-10-16 affecting Boeing B747 model aircraft, the US Federal Aviation Administration (FAA) issued an AD that CASA subsequently assessed. Based on this assessment, CASA decided to cancel Australian AD/B747/271, effective 6 July 2006, as the unsafe condition had been addressed by another AD. This action was taken in accordance with Australia’s obligations under the Convention on International Civil Aviation and without the need for public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The cancellation was executed by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, under subsection 84A(2) of the Act. This process ensures that Australian aviation regulations remain aligned with international standards and that any safety concerns are promptly addressed.
