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 Transport Canada has issued AD CF-2005-22 affecting Bell 206 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 206/159, which will become effective on 1 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 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, enacted by the Australian Parliament, was introduced to regulate civil aviation within Australia, with a primary focus on ensuring the safety of air navigation. The Act provides the legislative framework under which the Civil Aviation Safety Regulations 1998 were established, with regulation 39.001 specifically empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for aircraft and aeronautical products. These ADs serve as crucial tools for maintaining the continuing airworthiness of aircraft types as mandated by international standards, particularly under Annex 8 to the Convention on International Civil Aviation. The recent issuance of Australian AD/BELL 206/159 by CASA in response to an AD from Canada exemplifies the practical application of these regulations. This particular AD, which became effective on 1 September 2005, was issued due to Australia's obligations under international civil aviation conventions and was developed without public consultation as it pertains to fulfilling international regulatory requirements. The AD was issued by the Manager, Airframes in CASA’s Manufacturing, Certification and New Technologies Office, in accordance with the Act’s provisions.
Scope and Application
The Civil Aviation Safety Regulations 1998 apply to all individuals, businesses, and entities involved in the design, manufacture, maintenance, and operation of aircraft within Australia, including domestic and foreign-registered aircraft. The regulations govern the continuing airworthiness of aircraft, which is a key safety consideration under the Civil Aviation Act 1988. Airworthiness directives, which are issued under regulation 39.001, serve as legally binding mandates for the compliance with specific safety requirements for particular types of aircraft or aeronautical products. These directives are subject to disallowance under section 46A of the Acts Interpretation Act 1901 and are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. While the ADs are issued in response to international obligations and the directives of the State of Design, they do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The Australian airworthiness directives are issued by the Civil Aviation Safety Authority (CASA) and apply to aircraft registered in Australia, ensuring that they meet the required safety standards and continuing airworthiness criteria.
Key Provisions
The Civil Aviation Act 1988 (sections 98 and 84A) empowers the Governor-General to make regulations to ensure the safety of air navigation, while section 84A(2) specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain aircraft types or aeronautical products. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further specifies that CASA can issue such directives, which are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. These ADs are essential tools for maintaining the continuing airworthiness of aircraft types, as mandated by Annex 8 of the Convention on International Civil Aviation.
The obligations under these provisions require CASA to assess and, if necessary, issue Australian ADs that reflect the requirements of ADs issued by the State of Design. In this context, the State of Design has the primary responsibility for ensuring the continuing airworthiness of aircraft types and must provide any necessary information to relevant States of Registry. The State of Registry, in this case CASA, must then develop or adopt requirements to ensure the continuing airworthiness of aircraft registered in Australia. When a State of Design issues an AD, such as AD CF-2005-22 from Transport Canada affecting Bell 206 model helicopters, CASA must evaluate this information and issue a corresponding Australian AD, as demonstrated by AD/BELL 206/159, which was issued to address the safety concerns identified by the State of Design.
Failure to comply with the requirements set out in an AD may result in significant consequences. Under the Civil Aviation Act 1988, non-compliance can lead to the grounding of aircraft or the prohibition of flight operations until the specified safety measures are implemented. This ensures that all aircraft registered in Australia meet the necessary safety standards. Additionally, there are potential civil and criminal penalties for breaches of ADs, which can include substantial fines and imprisonment, depending on the severity of the violation. The maximum penalties for contravening airworthiness directives can be significant, reflecting the importance of adhering to these safety requirements.
