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-2007-14 affecting Bell 407 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 407/31, which will become effective on 03 October 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 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 was enacted to provide a comprehensive legal framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation and aircraft operations. One significant aspect of this legislation is its delegation to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. This authority is exercised in accordance with section 98 of the Act and serves the overarching policy objective of maintaining and enhancing the safety of air navigation. ADs are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These directives are crucial for the continuing airworthiness of aircraft types and are issued in response to international obligations under the Convention on International Civil Aviation, particularly Annex 8. In the case of Transport Canada issuing AD CF-2007-14 affecting Bell 407 model helicopters, CASA has assessed the directive and issued Australian AD/BELL 407/31, effective from 03 October 2007, to align with international standards and ensure the safety of aircraft registered in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products to ensure the safety of air navigation, as mandated by the Civil Aviation Act 1988. These ADs are legislative instruments that have the capacity to be disallowed under section 46A of the Acts Interpretation Act 1901, and they are subject to the oversight provisions of the Legislative Instruments Act 2003. ADs serve as the primary means of communicating continuing airworthiness information and are issued by most states that are party to the Convention on International Civil Aviation. The State of Registry, in this case CASA for Australia, has the responsibility of ensuring the continuing airworthiness of individual aircraft and must implement any necessary ADs issued by the State of Design, such as Transport Canada in the case of the Bell 407 model helicopter, to comply with international obligations. This process often does not require public consultation or a Regulatory Impact Statement, as ADs are based on international standards and directives.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, allows the Governor-General to establish regulations aimed at ensuring the safety of air navigation. In accordance with regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. This framework allows CASA to mandate specific requirements to maintain the airworthiness of aircraft registered in Australia.
Under these regulations, CASA must act on any ADs issued by the State of Design, which is the country responsible for the aircraft type's design. This obligation is in line with Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type. The State of Registry, which in Australia is CASA, must then develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. For instance, when Transport Canada issued AD CF-2007-14 for Bell 407 model helicopters, CASA assessed this directive and issued its own Australian AD/BELL 407/31, which became effective on 3 October 2007.
The obligations imposed on CASA and other relevant authorities include the assessment and implementation of ADs from the State of Design, ensuring that Australian registered aircraft comply with these requirements. This process is streamlined due to Australia's obligations under the Convention on International Civil Aviation, and no public consultation is required for such ADs as they are considered necessary for international compliance. The Office of Best Practice Regulation has also determined that ADs do not necessitate a Regulatory Impact Statement. CASA issues these directives under the authority granted by subsection 84A(2) of the Act, ensuring that the legislative requirements are met.
In terms of consequences for non-compliance, breaches of the Civil Aviation Act 1988 and associated regulations can lead to both civil and criminal penalties. The specific penalties are not detailed in the provided text, but generally, violations of airworthiness directives can result in fines, suspension or revocation of airworthiness certificates, and potentially criminal charges for individuals found guilty of serious violations. The severity of the penalties often depends on the nature and extent of the breach, with more severe infractions resulting in harsher penalties.
