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 has issued AD CF-2008-11R1 affecting Bombardier DHC-8 aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/137, Amendment 1, which will become effective on 31 July 2008. This AD cancels and replaces the previous issue.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to ensure the safety of air navigation, empowers the Governor-General to make regulations that serve the interests of aviation safety. Within this legislative framework, the Civil Aviation Safety Regulations 1998 were established, granting the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives are essential for maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. Given that ADs are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, CASA, as Australia’s national airworthiness authority, has the responsibility to assess and, where necessary, issue ADs that align with international standards and obligations. The issuance of ADs typically does not require public consultation, as they are responses to directives issued by the State of Design, and are not subject to a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. These directives, which are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, are essential for maintaining the continuing airworthiness of aircraft in line with international standards set by the Convention on International Civil Aviation. The State of Registry, in this case CASA as Australia’s national airworthiness authority, has the responsibility to ensure the continuing airworthiness of aircraft on the Australian Register by assessing and issuing Australian ADs in response to directives from the State of Design. For example, CASA issued AD/DHC-8/137, Amendment 1, to address an AD raised by Transport Canada for Bombardier DHC-8 aircraft, reflecting Australia’s adherence to international civil aviation obligations. Due to the nature of these directives and their basis in international convention, no public consultation is required, and the Office of Best Practice Regulation has determined that a Regulatory Impact Statement is unnecessary.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations that serve the Act’s purpose and the interests of air navigation safety. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, allows 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 under section 6 of the Legislative Instruments Act 2003.
Under these regulations, the State of Design, which is the country where the aircraft is designed, holds the responsibility for ensuring the ongoing airworthiness of an aircraft type. This obligation includes providing necessary information to the State of Registry—the country where the aircraft is registered—to maintain airworthiness. When a State of Design issues an AD, the State of Registry must evaluate this information and, if necessary, issue its own AD to enforce the State of Design’s requirements. In Australia, CASA, as the national airworthiness authority, performs this role. For example, CASA issued AD/DHC-8/137, Amendment 1, in response to Transport Canada’s AD CF-2008-11R1 affecting Bombardier DHC-8 aircraft, effective from 31 July 2008.
The obligations imposed by these regulations are significant. CASA must carefully assess any ADs issued by the State of Design and determine their applicability to aircraft registered in Australia. If an AD is deemed necessary, CASA must issue an Australian AD to ensure compliance. This process ensures that aircraft continue to meet safety standards, aligning with Australia’s obligations under the Convention on International Civil Aviation. Additionally, these ADs do not require public consultation or a Regulatory Impact Statement, as they are issued in response to international obligations and directly related to maintaining airworthiness.
The implications of non-compliance with these regulations can be severe. Failure to adhere to an AD can result in civil or criminal penalties. The Civil Aviation Safety Regulations 1998 outline potential penalties for breaches, which can include substantial fines and, in more serious cases, imprisonment. Specifically, the maximum penalties can vary depending on the severity and intent of the breach but are designed to enforce compliance and ensure the safety of air navigation. CASA has the authority to take enforcement actions against entities that fail to comply with ADs, highlighting the importance of adhering to these regulatory requirements.
