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-2006-10 affecting Bombardier DHC-8 model aircraft. Canada is the state of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/124, which will become effective on 3 August 2006.
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, is fundamental in governing the aviation industry in Australia, with the objective of ensuring safety and efficiency in air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were established, allowing the issuance of airworthiness directives (ADs) to ensure the continuing airworthiness of aircraft. ADs, as legislative instruments, mandate specific actions to be taken regarding the maintenance, inspection, or repair of aircraft to ensure safety. This legislative framework responds to the international obligations under the Convention on International Civil Aviation, particularly the requirement for States of Design and Registry to ensure the continuing airworthiness of aircraft types. The Civil Aviation Safety Authority (CASA) plays a pivotal role in this process, assessing international ADs and issuing corresponding Australian ADs as necessary, as demonstrated by the recent Australian AD/DHC-8/124 issued in response to a Canadian AD affecting Bombardier DHC-8 model aircraft. This process underscores the collaborative nature of international aviation safety standards and the critical role of CASA in implementing these standards within Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulation serves to uphold the safety standards required by the Civil Aviation Act 1988. These ADs are legally binding and must be adhered to by all relevant parties, ensuring compliance with national and international aviation safety standards. Geographically, the application of these regulations and the subsequent ADs is confined to Australian territory, with CASA as the national airworthiness authority responsible for enforcing these directives. Exemptions and exclusions are not explicitly detailed in the given excerpt, but the nature of ADs typically does not provide for exclusions, as they are designed to maintain the highest safety standards across the industry. Additionally, the ADs can extend their reach through subordinate instruments as necessary, reflecting the dynamic and evolving nature of aviation safety regulations.
Key Provisions
The Civil Aviation Act 1988, particularly under section 98, empowers the Governor-General to enact regulations for the safety of air navigation, which includes the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further specifies that CASA is authorised to issue ADs for certain types of aircraft or aeronautical products. Section 39.001(5) of these regulations classifies an AD as a disallowable instrument, and consequently, a legislative instrument under section 6 of the Legislative Instruments Act 2003. This means that ADs are formally recognised as binding legal instruments within the Australian legislative framework.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on the entities they govern are primarily centred on the maintenance of aircraft safety and airworthiness. The State of Design, in this case, Canada, holds the responsibility for the continuing airworthiness of the aircraft type in question and must provide necessary information to ensure this. The State of Registry, which is Australia in this scenario, must adopt or develop requirements to ensure the continuing airworthiness of the aircraft registered within its jurisdiction. CASA, as the national airworthiness authority, is tasked with assessing information from the State of Design and, when necessary, issuing an Australian AD to enforce the requirements of the State of Design.
Under the Convention on International Civil Aviation, the State of Registry, in this case, Australia, must respond to ADs issued by the State of Design to ensure that aircraft within its registry maintain their airworthiness. Failure to comply with an AD can result in severe consequences, including potential grounding of the aircraft, which can disrupt operations and lead to significant financial and safety risks. CASA has issued AD/DHC-8/124 as a response to AD CF-2006-10 by Transport Canada, which affects Bombardier DHC-8 model aircraft. This AD will become effective on 3 August 2006, and it is imperative that all relevant parties comply with the mandated requirements to ensure the safety and airworthiness of these aircraft.
There are no public consultations or regulatory impact statements required for the issuance of ADs such as AD/DHC-8/124, as these are issued in accordance with Australia’s international obligations under the Convention on International Civil Aviation. The Manager, Airframes in the Manufacturing, Certification and New Technologies Office, has made this AD on behalf of CASA, in line with subsection 84A(2) of the Act. Non-compliance with ADs can lead to severe penalties, including criminal charges and substantial fines, as well as potential civil liabilities for any accidents or incidents arising from non-compliance. The maximum penalties for breaches of ADs may vary, but they are designed to ensure strict adherence to the safety standards mandated by CASA.
