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 2007-11-05 affecting Sikorsky S-76 model helicopters. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/S-76/75, which will become effective on 15 June 2007.
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 establish a comprehensive legal framework governing all aspects of civil aviation in Australia, ensuring safety and efficiency in the industry. This Act empowers the Governor-General to make regulations aimed at enhancing the safety of air navigation, a critical aspect of public safety and economic activity. One such regulation, the Civil Aviation Safety Regulations 1998, includes the ability for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the continuing airworthiness of aircraft and aeronautical products. These directives are a legislative instrument under the Acts Interpretation Act 1901, reflecting their importance and the need for oversight in their creation. The policy objective underpinning these regulations is to maintain and improve the safety standards of Australian civil aviation in alignment with international obligations, specifically under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, through its regulation 39.001, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, thereby establishing safety standards and procedures that are integral to the aviation industry. These ADs are legislative instruments under the Legislative Instruments Act 2003, and they must align with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The ADs apply to aircraft registered in Australia, imposing responsibilities on the State of Registry to ensure compliance with continuing airworthiness requirements. This legislative framework ensures that CASA, as Australia's national airworthiness authority, can effectively manage the safety of aircraft operating within Australian jurisdiction, in line with international obligations. Notably, the issuance of ADs such as the one for the Sikorsky S-76 model helicopters, following assessment of a corresponding directive from the US Federal Aviation Administration (FAA), does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the procedures and requirements for issuing airworthiness directives (ADs) for aircraft and aeronautical products. Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Regulations enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. The ADs are essential for ensuring the continuing airworthiness of aircraft, aligning with the State of Design's responsibility under Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these provisions primarily focus on CASA's role in ensuring that the airworthiness directives issued are consistent with international standards and are implemented effectively within Australia. CASA must assess information from the State of Design and, if necessary, issue corresponding Australian ADs to mandate the required safety measures. This process is crucial for maintaining the safety and airworthiness of aircraft registered in Australia, ensuring that they meet the safety standards set by the International Civil Aviation Organization (ICAO). The State of Registry also has the responsibility to develop or adopt requirements to ensure the continuing airworthiness of aircraft within their jurisdiction.
Failure to comply with an airworthiness directive can result in significant consequences, both civil and criminal. Civil penalties can include fines and enforcement actions taken by CASA to ensure compliance. In more severe cases, non-compliance may lead to criminal charges, particularly if the non-compliance results in a safety incident or accident. The maximum penalties for such offences can vary, but they may include substantial fines and imprisonment, reflecting the serious nature of ensuring air safety and compliance with airworthiness directives. These measures are in place to ensure that all stakeholders, including aircraft operators and manufacturers, adhere to the safety regulations set forth by CASA and the Civil Aviation Safety Regulations 1998.
