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.
Transport Canada have issued AD CF-49-05 affecting Canadian DHC-1 aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-1/44 which will become effective on 12 August 2011.
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 A/Manager, Continuing Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate the aviation industry in Australia, focusing on the safety and efficiency of air navigation. This legislation empowers the Governor-General to make regulations for the Act's purposes, as seen in the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments designed to ensure the continuing airworthiness of aircraft types and aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Authority (CASA) issues these directives to comply with Australia's obligations under the Convention on International Civil Aviation, ensuring that national airworthiness requirements are met without the need for public consultation or a Regulatory Impact Statement. This legislative framework underscores Australia's commitment to maintaining high safety standards in aviation, reflecting both national and international regulatory expectations.
Scope and Application
The Civil Aviation Safety Regulations 1998, as amended, apply to all aircraft registered in Australia and any aeronautical products used within Australia, ensuring compliance with international standards set by the Convention on International Civil Aviation. These regulations are designed to maintain the safety of air navigation and allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. Airworthiness directives are legislative instruments that mandate specific actions to ensure the continuing airworthiness of aircraft, and they fall under the purview of the State of Registry, which in Australia's case is CASA. The ADs are issued in response to international obligations and the requirements of the aircraft's State of Design, with CASA ensuring that any directives issued by other states are appropriately adopted and enforced in Australia. While these directives are necessary to uphold safety standards and are informed by international agreements, they do not require public consultation or a Regulatory Impact Statement, as they are a direct response to international obligations and are assessed by CASA as part of their regulatory function.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to establish regulations for the Act's purposes and to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further mandates the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments as they are disallowable under section 46A of the Acts Interpretation Act 1901 and are subject to the Legislative Instruments Act 2003.
Obligations and requirements under these regulations include that the State of Design, which is the country where the aircraft type is designed, must ensure the continuing airworthiness of the aircraft type and provide necessary information to the States of Registry, which are responsible for the individual aircraft's airworthiness. When the State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must assess this information and, if deemed necessary, issue an Australian AD. For instance, Transport Canada issued AD CF-49-05 for Canadian DHC-1 aircraft, leading CASA to issue Australian AD/DHC-1/44, which became effective on 12 August 2011.
There are specific procedures and processes governing the issuance and implementation of ADs. Since ADs are issued under Australia’s obligations under the Convention on International Civil Aviation and in response to an AD from the State of Design, they do not require public consultation. Additionally, the Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement. The AD in question was made by the A/Manager, Continuing Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94(1) of the Act.
Offences and penalties for non-compliance with ADs can be severe. Under the Civil Aviation Act 1988, failure to comply with an AD can result in both civil and criminal penalties. Civil penalties may include fines, while criminal penalties can include imprisonment. The maximum penalties are detailed within the Act, reflecting the critical importance of adhering to airworthiness directives to maintain the safety standards of air navigation.
